. Post, P.; Milne, A.; Li Bingjian 1995-09-11 Many oil exploration companies view China as a country of moderate upside potential with little opportunity for new giant discoveries. This view may be pessimistic given the structural complexity of some areas within certain basins in western, southern, and southwestern China and the lack of drilling in some peripheral basins onshore China. China`s tremendous economic modernization drive necessitates that companies be cognizant of its domestic exploration and production opportunities (the greatest of all dragons must be fed). This article reviews recent foreign involvement in onshore exploration and is a response to the June 1995 announcement by Chinese National Petroleum Corp. (CNPC) of the third onshore licensing round.

Mink, R.M.; Bearden, B.L.; Mancini, E.A. 1989-01-01 To date, numerous Jurassic hydrocarbon fields and pools have been discovered in the Cotton Valley Group, Haynesville Formation, Smackover Formation and Norphlet Formation in the tri-state area of Mississippi, Alabama and Florida, and in Alabama State coastal waters and adjacent Federal waters area.
Petroleum traps are basement highs, salt anticlines, faulted salt anticlines and extensional faults associated with salt movement. Reservoirs include continental and marine sandstones, limestones and dolostones. Hydrocarbon types are oil, condensate and natural gas. The onshore stratigraphic and structural information can be used to establish a regional geologic framework for the Jurassic for the State coastal waters and adjacent Federal waters areas.
Evaluation of the geologic information along with the hydrocarbon data from the tri-state area indicates that at least three Jurassic hydrocarbon trends (oil, oil and gas condensate, and deep natural gas) can be identified onshore. These onshore hydrocarbon trends can be projected into the Mobile area in the Central Gulf of Mexico and into the Pensacola, Destin Dome and Apalachicola areas in the Eastern Gulf of Mexico. Substantial reserves of natural gas are expected to be present in Alabama State waters and the northern portion of the Mobile area.
Significant accumulations of oil and gas condensate may be encountered in the Pensacola, Destin Dome, and Apalachicola areas.??. Kilsgaard, Thor H.; Tuchek, Ernest T. 1984-01-01 On the basis of a mineral survey of the Eagle Cap Wilderness and adjacent areas a probable mineral-resources potential was identified in five areas in the eastern part of the wilderness. Mineral resources are most likely to occur in tactite deposits in sedimentary rocks at or near contacts with intrusive granitic rocks that could contain copper and small amounts of other metals; however, there is little promise for the occurrence of energy resources.

Dartnell, Pete; Conrad, James E.; Stanley, Richard G.; Guy R. Cochrane, Guy R. 2011-01-01 Geologic maps that span the shoreline and include both onshore and offshore areas are potentially valuable tools that can lead to a more in depth understanding of coastal environments. Such maps can contribute to the understanding of shoreline change, geologic hazards, both offshore and along-shore sediment and pollutant transport. They are also useful in assessing geologic and biologic resources.
Several intermediate-scale (1:100,000) geologic maps that include both onshore and offshore areas (herein called onshore-offshore geologic maps) have been produced of areas along the California coast (see Saucedo and others, 2003; Kennedy and others, 2007; Kennedy and Tan, 2008), but few large-scale (1:24,000) maps have been produced that can address local coastal issues. A cooperative project between Federal and State agencies and universities has produced an onshore-offshore geologic map at 1:24,000 scale of the Coal Oil Point area and part of the Santa Barbara Channel, southern California (fig. As part of the project, the U.S. Geological Survey (USGS) and the California Geological Survey (CGS) hosted a workshop (May 2nd and 3rd, 2007) for producers and users of coastal map products (see list of participants) to develop a consensus on the content and format of onshore-offshore geologic maps (and accompanying GIS files) so that they have relevance for coastal-zone management. The USGS and CGS are working to develop coastal maps that combine geospatial information from offshore and onshore and serve as an important tool for addressing a broad range of coastal-zone management issues.
The workshop was divided into sessions for presentations and discussion of bathymetry and topography, geology, and habitat products and needs of end users. During the workshop, participants reviewed existing maps and discussed their merits and shortcomings. This report addresses a number of items discussed in the workshop and details the onshore and offshore geologic map of the Coal Oil. Kiilsgaard, Thor H.; Patten, Lowell L. 1984-01-01 The results of a mineral survey of the Cloud Peak Primitive Area and adjacent areas in Wyoming indicated little promise for the occurrence of mineral resources.
There are some prospect workings, particularly in the northern part of the area, but in none of them were there indications that ore had been mined. Samples from the workings, from nearby rocks and sediments from streams that drain the area did not yield any metal values of significance. The crystalline rocks that underlie the area do not contain oil and gas or coal, products that are extracted from the younger rocks that underlie basins on both sides of the study area.
Keith, T.E.C.; Causey, J.D. 1984-01-01 A mineral survey of the Mount Hood Wilderness, Oregon, was conducted in 1980. Geochemical data indicate two areas of substantiated mineral-resource potential containing weak epithermal mineralization: an area on the north side of Zigzag Mountain, where vein-type lead-zinc-silver deposits occur and an area on the south side of Zigzag Mountain, where the upper part of a quartz diorite pluton has propylitic alteration associated with mineralization of copper, gold, silver, lead, and zinc in discontinuous veins. Geothermal-resource potential for low- to intermediate-temperature (less than 248/sup 0/F) hot-water systems in the wilderness is probable in three areas. Part of the wilderness is classified as a Known Geothermal Resource Area (KGRA), which is considered to have probable geothermal-resource potential, and two parts of the wilderness have been included in geothermal lease areas.

1984-01-01 The Goat Rocks Wilderness and adjacent roadless areas are a rugged, highly forested, scenic area located on the crest of the Cascade Range in south-central Washington. Several mineral claims have been staked in the area. Mineral surveys were conducted. Geochemical, geophysical, and geologic investigations indicate that three areas have probable mineral-resource potential for base metals in porphyry-type deposits. Available data are not adequate to permit definition of the potential for oil and gas. There is little likelihood for the occurrence of other kinds of energy resources in the area. Evaluation of resource potential in the three areas identified as having probable mineral-resource potential could be improved by more detailed geochemical studies and geologic mapping.
Xia, S.; Qiu, X.; Wan, K. 2015-12-01 We used active source wide-angle seismic data to determine a crustal structure beneath the onshore-offshore area of Hong Kong at the southern end of a broad belt dominated by Late Mesozoic intrusive and extrusive rocks in the coastal region of Southeast China. High-resolution tomographic images provide direct seismic evidence for the magmatic plumbing system of Late Mesozoic calderas. A localized high-velocity anomaly is revealed in the lower crust offshore between Hong Kong and Dangan Island, which may reflect basaltic underplating that induced voluminous silicic eruptions and granitoid plutons in the onshore-offshore area of Hong Kong.
Tilted high-velocity zones are revealed in the entire crust beneath Dangan Island and the Late Mesozoic calderas of Hong Kong, which may reflect ascending magma chambers. We propose a paleo-Pacific plate subduction model to interpret our tomographic results and the generation of strong granitic magmatism in the Hong Kong area. Combining the tomographic image beneath the Lianhuashan Fault Zone with the distribution of Late Mesozoic calderas, we infer that the Lianhuashan Fault Zone might be the dominant magmatic conduit for mantle-derived magmas ascending to the upper crust.
In addition, intersecting faults with different orientations could control the distribution and geometry of the vents, calderas, dykes and plutons and play an important role in forming magma conduits for individual volcanoes.

Cheng, Shengyao The Pn tomography method utilizes seismic waves that refract along the Moho interface to perform inversion in order to investigate velocity anomalies and seismic anisotropy in the uppermost mantle. Results from Pn tomography can provide important information about the composition, temperature, and tectonic processes beneath the study area. Over the past decades, numerous seismic and geologic studies have been conducted in the Colorado Plateau and its adjacent areas to reveal crustal and mantle structures and processes responsible for the diverse surface geological features and tectonic events that have occurred in this area. To investigate lateral variations in the uppermost mantle in terms of temperature, composition and orientation of anisotropic fabrics beneath Colorado Plateau and adjacent areas, the Pn tomography method was applied.
The current research uses data from 468 local earthquakes recorded by 186 stations from the Incorporated Research Institutions for Seismology Data Management Center. A total of 2548 seismograms were used to invert the velocity and anisotropic structures. Resulting low velocity anomalies beneath the westernmost part of the CP suggest a high-temperature top mantle, probably as a result of active mantle upwelling and hot asthenosphere replacement of cold lithosphere. In contrast, the high velocity anomaly represents cool and stable uppermost mantle. In comparison with the shear wave splitting and shear stress results, the fast orientation of Pn wave anisotropy may reflect the extension direction of Basin and Range and Rio Grand Rift studies. Janutyte, Ilma; Kozlovskaya, Elena; Motuza, Gediminas 2013-05-01 The territory of Lithuania and adjacent areas of the East European Craton have always been considered a region of low seismicity.
Two recent earthquakes with magnitudes of more than 5 in the Kaliningrad District (Russian Federation) on 21 September 2004 motivated re-evaluation of the seismic hazard in Lithuania and adjacent territories. A new opportunity to study seismicity in the region is provided by the PASSEQ (Pasive Seismic Experiment) project that aimed to study the lithosphere-asthenosphere structure around the Trans-European Suture Zone. Twenty-six seismic stations of the PASSEQ temporary seismic array were installed in the territory of Lithuania.
The stations recorded a number of local and regional seismic events originating from Lithuania and adjacent areas. This data can be used to answer the question of whether there exist seismically active tectonic zones in Lithuania that could be potentially hazardous for critical industrial facilities. Therefore, the aim of this paper is to find any natural tectonic seismic events in Lithuania and to obtain more general view of seismicity in the region. In order to do this, we make a manual review of the continuous data recorded by the PASSEQ seismic stations in Lithuania. From the good quality data, we select and relocate 45 local seismic events using the well-known LocSAT and VELEST location algortithms. In order to discriminate between possible natural events, underwater explosions and on-shore blasts, we analyse spatial distribution of epicenters and temporal distribution of origin times and perform both visual analysis of waveforms and spectral analysis of recordings.
We show that the relocated seismic events can be grouped into five clusters (groups) according to their epicenter coordinates and origin and that several seismic events might be of tectonic origin. We also show that several events from the off-shore region in the Baltic Sea (at the coasts of the Kaliningrad District of the Russian Federation) are. Mohamed, R.

A.; Lajis, A.; Kassim, A. 2016-07-01 Air quality in the residential areas adjacent to the industrial regions is of great concern due to the association with human health risks. In this work, the concentrations of particulate matter (PM10) in the ambient air of UTHM campus was investigated tostudy the air qualityand their compliance to the Malaysian Ambient Air Quality Guidelines (AAQG).
The PM10 samples were taken over 24 hours from the most significant area at UTHM including Stadium, KolejKediamanTunDr. Ismail (KKTDI) and MakmalBahan. The meteorological parameters; temperature, relative humidity, wind speed and wind direction as well as particulate matterwere estimated by using E-Sampler Particulate Matter (PM10) Collector. The highest concentrations of PM10 (55.56 µg/m3) was recorded at MakmalBahan during the working and weekend days. However, these concentrations are less than 150 pg/m3. It can be concluded that although UTHM is surrounded by the industrial area, the air quality in the campus still within the standards limits.
Missallati, A.A. Ltd., Tripoli ) 1988-08-01 According to the age of major reservoirs, hydrocarbon occurrences in Libya and adjacent areas can be grouped into six major systems which, according to their geographic locations, can be classified into two major hydrocarbon provinces: (1) Sirte-Pelagian basins province, with major reservoirs ranging from middle-late Mesozoic to early Tertiary, and (2) Murzog-Ghadames basins province, with major reservoirs ranging from early Paleozoic to early Mesozoic. In the Sirte-Pelagian basins province, hydrocarbons have been trapped in structural highs or in stratigraphic wedge-out against structural highs and in carbonate buildups. Here, hydrocarbon generation is characterized by the combined effect of abundant structural relief and reservoir development in the same hydrocarbon systems of the same age, providing an excellent example of hydrocarbon traps in sedimentary basins that have undergone extensive tensional fracturing in a shallow marine environment.
In the Murzog-Ghadames basins province, hydrocarbons have been trapped mainly in structural highs controlled by paleostructural trends as basement arches which acted as focal points for oil migration and accumulation. Willingham, C. Richard; Rietman, Jan D.; Heck, Ronald G.; Lettis, William R. 2013-01-01 The Hosgri Fault Zone trends subparallel to the south-central California coast for 110 km from north of Point Estero to south of Purisima Point and forms the eastern margin of the present offshore Santa Maria Basin. Knowledge of the attributes of the Hosgri Fault Zone is important for petroleum development, seismic engineering, and environmental planning in the region. Because it lies offshore along its entire reach, our characterizations of the Hosgri Fault Zone and adjacent structures are primarily based on the analysis of over 10,000 km of common-depth-point marine seismic reflection data collected from a 5,000-km2 area of the central and eastern parts of the offshore Santa Maria Basin.
We describe and illustrate the along-strike and downdip geometry of the Hosgri Fault Zone over its entire length and provide examples of interpreted seismic reflection records and a map of the structural trends of the fault zone and adjacent structures in the eastern offshore Santa Maria Basin. The seismic data are integrated with offshore well and seafloor geologic data to describe the age and seismic appearance of offshore geologic units and marker horizons. We develop a basin-wide seismic velocity model for depth conversions and map three major unconformities along the eastern offshore Santa Maria Basin. Accompanying plates include maps that are also presented as figures in the report. Appendix A provides microfossil data from selected wells and appendix B includes uninterpreted copies of the annotated seismic record sections illustrated in the chapter.
Features of the Hosgri Fault Zone documented in this investigation are suggestive of both lateral and reverse slip. Characteristics indicative of lateral slip include (1) the linear to curvilinear character of the mapped trace of the fault zone, (2) changes in structural trend along and across the fault zone that diminish in magnitude toward the ends of the fault zone, (3) localized compressional and extensional structures. 2011-10-01., and other production or development purposes, or for repressuring or recycling in accordance with a.

Unitized Federal land as provided in Section 12 at the rates specified in the respective Federal leases. Gao, Y.; Chen, L. 2016-12-01 Based on GPS results, it's been proposed that the continental collision between the Indian and Eurasian plates and the obstruction of the rigid Sichuan Basin jointly contributed to the steep rise of Longmen Shan (LMS). However, GPS results are insufficient to constrain the feature of the upper mantle deformation and to determine whether it contributes to the topographic relief across the LMS fault belt.
To investigate the roles played by the upper mantle in the uplift and expansion processes of the tibetan Plateau and the interactions of the plateau with surrounding blocks, we studied the seismic anisotropy structure of the upper mantle in LMS and adjacent areas by teleseismic shear wave splitting analyses. We obtained the splitting parameters for seismic stations forming two nearly perpendicular linear arrays that cross the eastern margin of the Tibetan Plateau and the Sichuan Basin. We carefully analyzed the features of shear wave splitting and its spatial variations in this region and then delineate the pattern of upper mantle deformation by comparing our results with GPS results, the direction of absolute plate motion (APM), surface structures and crustal anisotropy.
Our results show that the fast direction of shear waves in the LMS fault belt is subparallel to the fault strike, consistent with the stress distribution. Near tectonic boundaries, such as the Kunlun fault, and in the Yun-Gui Plateau, the fast directions are also subparallel to the fault strikes and agree with GPS observations. This suggests that in these areas tectonism may have ererted important impacts on the upper mantle deformation and the crust and upper mantle probably deformed in a vertically coherent way. In contrast, double-layer anisotropy was observed in the Qilian orogenic belt, which corroborates previous studies and indicates tectonic decoupling of the crust-mantle system.
The fast direction in the Sichuan Basin is dominantly NW, close to the direction of APM. One possibility for.
Scott, J.; Dolan, P.; Lunn, G. ) 1988-08-01 Post-Hercynian deposits in the eastern Adriatic and the adjacent external zones of the Dinarides and Albanian Hellenides may be subdivided into four facies groups. (1) Permian-Lower Triassic clastics and carbonates with some evaporites, (2) Middle Triassic-lower Tertiary carbonate platform facies with associated continental margin deeper marine sequences, (3) Upper Cretaceous-lower Tertiary flysch, and (4) middle Tertiary molasse and postorogenic Neogene sediments. The Permian to lower Tertiary section was deposited during the complex Alpine cycle, while the upper Tertiary section is the product of post-Alpine deposition. This depositional history during markedly different tectonic regimes creates two groups of petroleum plays in the eastern Adriatic: (1) Alpine cycle plays in the Permian to lower Tertiary in the thrust-faulted and folded foreland of Adria and (2) post-Alpine plays in upper Tertiary postorogenic or late synorogenic basins.
Around the Adriatic, the post-Alpine plays have so far proved the most successful. Major production occurs in the onshore Po basin and its extension beneath the Adriatic. Some of this production is from deep Alpine-cycle reservoirs, but the bulk is from the upper Tertiary-Quaternary. Similar horizons produce onshore and offshore the central-southern Adriatic coast of Italy.
Major Tertiary production also occurs to the northeast in the Pannonian basin of Yugoslavia and Hungary from Miocene and younger sequences. Onshore Albania produces significant quantities of hydrocarbons; although data are scarce, much of this production is presumably from upper Tertiary molasse or lower Tertiary flysch. 2014-07-01. 33 Navigation and Navigable Waters 2 2014-07-01 false Lake Tahoe, Nev.; restricted area adjacent to Nevada Beach. 162.215 Section 162.215 Navigation and Navigable Waters COAST GUARD, DEPARTMENT.

Trapp, Henry; Pascale, C.A.; Foster, J.B. 1977-01-01 Okaloosa County, in the northwest Florida panhandle, uses the Floridan aquifer for water supply, although it also has abundant surface water and ground water in the surficial sand-and-gravel aquifer. Water levels have declined locally more than 90 feet in the upper limestone of the Floridan aquifer. The Floridan aquifer is overlain by the Pensacola clay confining bed, and the Bucatunna Clay subdivides it into two limestone units. Water in the upper limestone is generally of good quality. The lower limestone probably contains saline water.
Average daily stream discharge is about 2,500 million gallons. Stream discharge does not diminish excessively during droughts, owing to high base runoff. Water levels in the Floridan aquifer will decline as long as pumping increases in the present areas of withdrawal. The decline could be alleviated by redistribution of pumping, artificial recharge, and the use of the sand-and-gravel aquifer or streams. (Woodard-USGS).

) 1990-05-01 Analysis of 38 contiguous Landsat Multispectral Scanner scenes acquired over Myanmar (Burma) reveals numerous large-scale features associated with margins of the Burman plate, previously unidentified northeast-southwest-trending discontinuities, important extensions of previously mapped fault trends, and numerous structural features that appear favorable for petroleum exploration. A mosaic of these scenes at 1:1,000,000 scale shows a large number of tectonic elements and their spatial relationships. Within the area of investigation are portions of the Indian, Burman, Lhasa, and Shan-Thai plates, and perhaps other, smaller plates. The Himalayan front and Indo-Burman Ranges manifest effects of current and recently past plate movement. The complexity of the kinematic history accounts for the diversity of structural features in the area. The last major event in this long and violent saga, which began in middle Miocene (approximately 11 Ma) time and continues to the present, is the recent change from a collisional to a right-lateral strike-slip transform margin between the Indian and Burman plates.
The complexity of the structures visible is the product of multiple plate collisions, rotation of the Indian plate and parts of the Asian plate, and long-continued convergence that changed velocity and direction tbrough time. The most obvious evidence of this complexity, which is immediately apparent on geologic maps or the Landsat mosaic of the region, is the almost right-angle relationship of the folds of the Indo-Burman Ranges and the frontal thrusts and suture zones of the Himalaya. These two sets of compressive features imply maximum compressive stress axes that lie at right angles to each other. The implications are either that the orientation of the stress field changes rapidly over a short distance or that the stress field has changed through time. Both occurrences seem to be true.
Thomas 2005-01-01 The study area comprises the Humboldt River Basin and adjacent areas, with emphasis on mining areas relatively close to the Humboldt River. The basin comprises about 16,840 mi2 or 10,800,000 acres. The mineral resources of the Humboldt Basin have been investigated by many scientists over the past 100 years, but only recently has our knowledge of regional geology and mine geology been applied to the understanding and evaluation of mining effects on water and environmental quality. The investigations reported here apply some of the techniques and perspectives developed in the Abandoned Mine Lands Initiative (AMLI) of the U.S. Geological Survey (USGS), a program of integrated geological-hydrological-biological-chemical studies underway in the Upper Animas River watershed in Colorado and the Boulder River watershed in, Montana. The goal of my studies of sites and districts is to determine the character of mining-related contamination that is actively or potentially a threat to water quality and to estimate the potential for natural attenuation of that contamination.
These geology-based studies and recommendations differ in matters of emphasis and data collection from the biology-based assessments that are the cornerstone of environmental regulations. 2010-07-01.

Chaffee, M.A.; Hill, R.H.; Sutley, S.J. 1984-01-01 The Hoover Wilderness and the adjacent Hoover Extension (East), Hoover Extension (West), and Cherry Creek A Roadless Areas (the adjacent study area) encompass approximately 153,900 acres (241 mi2; 623 km2) in the Inyo, Stanislaus, and Toiyabe Naitonal Forests, Mono and Tuolumne Counties, Calif.
These two areas lie along and mostly east of the crest of the Sierra Nevada, along the north and east sides of Yosemite National Park. Elevations vary from a high of 12,446 ft (3,793 m) on the crest of the Sierra Nevada to a low of about 6,500 ft (1,981 m) near the Bridgeport Ranger Station.
Access to the Hoover Wilderness and adjacent study area is by U.S. Highway 395, California State Highways 108 (Sonora Pass) and 120 (Tioga Pass), and by other paved and graded roads that lead off of these U.S. And State highways. 2010-07-01. 33 Navigation and Navigable Waters 3 2010-07-01 false San Diego Harbor, Calif.; naval.880 San Diego Harbor, Calif.; naval restricted area adjacent to Point Loma.

Prokof'eva, T. V.; Rozanova, M. S.; Poputnikov, V. 2013-03-01 The humus-accumulative horizons of soils from two natural-historical parks of Moscow and the adjacent residential areas were studied. An increase in the concentration of organic matter was observed in the soils of the residential areas. A tendency toward the formation of fulvate humus typical for southern taiga soils persisted in the low-carbonate nongleyed humus-accumulative horizons.
At the same time, the transformation rate, character, and content of organic matter in the urban soils were strongly affected by the contamination, calcareous invasion, and remediation of the soils and sediments. Earhart, Robert L.; Marks, Lawrence Y. 1984-01-01 Hydrocarbon and non-fuels mineral surveys indicate that parts of the Bob Marshall and Great Bear Wildernesses and several of the adjacent study areas have probable and substantiated mineral-resource potential for hydrocarbon accumulations, especially natural gas; the Scapegoat and Great Bear Wildernesses have a substantiated resource potential for copper and silver.

The Bob Marshall Wilderness has a substantiated potential for barite and a probable potential for copper and silver. Lead, zinc, coal, and limestone occur locally within the study areas but such occurrences are small and low grade and no resource potential is identified. Taylor, G.F.; Snell, L.J. 1978-01-01 This map report was prepared in cooperation with the Southwest Florida Water Management District which, with the Waccasassa River Basin Board, had jurisdiction over waters within the Waccasassa River basin, the coastal areas adjacent to the basin, and other adjacent areas outside the basin. New water management district boundaries, effective January 1977, place most of the Waccasassa River basin in the Suwannee River Water Management District.
The purpose of the report is to provide water information for consideration in land-use and water development which is accelerating, especially in the northeastern part of the study area. It is based largely on existing data in the relatively undeveloped area.
Of the total area included in the topographic drainage basin for the Waccasassa River about 72 percent is in Levy County, 18 percent in Alachua County, 9 percent in Gilchrist County, and 1 percent in Marion County. The elongated north-south drainage basin is approximately 50 mi in length, averages 13 mi in width, and lies between the Suwannee River, the St. Johns River, and the Withlacoochee River basins.

Walters, W.H.; Dirkes, R.L.; Napier, B.A. 1992-04-01 As part of the Hanford Environmental Dose Reconstruction Project, Pacific Northwest Laboratory reviewed literature and data on radionuclide concentrations and distribution in the water, sediment, and biota of the Columbia River and adjacent coastal areas. Over 600 documents were reviewed including Hanford reports, reports by offsite agencies, journal articles, and graduate theses. Certain radionuclide concentration data were used in preliminary estimates of individual dose for the 1964-1966 time period.
This report summarizes the literature and database review and the results of the preliminary dose estimates. Walters, W.H.; Dirkes, R.L.; Napier, B.A.

Kelly, T.E. 1973-01-01 Geohydrologic data have been obtained from more than 100 wells and test holes that have been drilled in the Post Headquarters and adjacent areas of White Sands Missile Range. Observation-well data show that, in general, a continuous decline of the water table has occurred in the vicinity of the well field since production began in 1949. Approximately 40,000 acre-feet of water has been produced from the aquifer to date (1972). A series of maps are presented which show the changes that have occurred in the well field as the result of development.

Human intervention resulted in water conditions ranging from complete anoxia in the polluted inner bay area to the adjacent, relatively pristine, open coastal area. In the present work the goals were to estimate nutrients and carbon fluxes between the bay and the adjacent coastal waters and to characterize by using stable isotopes, hydrocarbons and sterols the provenance of the exported/imported organic matter. Water samples were collected from three different depths over 25 hours cycles in the wet and dry seasons at a single station strategically positioned in the bay.
Measurements included CTD, nutrients, chlorophylls, DOC, POC, PN, δ13C and δ15N, hydrocarbons and sterols in SPM. Most substances showed higher concentrations in ebb tide events and through statistical tools a significant difference between the campaigns was proved. The fluxes estimated on annual basis revealed the expressive exportation to the inner continental shelf of 1.27x104 Kmol DIN yr-1, 9.52x102 Kmol DIP yr-1, 2.65x104 tons DOC yr-1, 1.96x104 tons COP yr-1, 2.96x104 tons NP yr-1.
