Estimating suspended sediment concentrations in turbid coastal waters of the Santa Barbara Channel with SeaWiFS
J.A. Warrick, L.A.K. Mertes, D.A. Siegel, C. Mackenzie
2004, International Journal of Remote Sensing (25) 1995-2002
A technique is presented for estimating suspended sediment concentrations of turbid coastal waters with remotely sensed multi-spectral data. The method improves upon many standard techniques, since it incorporates analyses of multiple wavelength bands (four for Sea-viewing Wide Field of view Sensor (SeaWiFS)) and a nonlinear calibration, which produce highly accurate...

The Chesapeake Bay Crater: Geology and geophysics of a Late Eocene submarine impact structure
C. Wylie Poag, Christian Koeberl, Wolf Uwe Reimold
2004, Book
The list of impact craters documented on Earth is short. Only about 165 genuine impact structures have been identified to date (Table 1.1). Even so, the number is steadily increasing at the rate of ∼3–5 per year (Grieve et al. 1995; Earth Impact Database at http://www.unb.ca/passc/Impact/Database/). In stark contrast, most...
Enhanced submarine ground water discharge form mixing of pore water and estuarine water
Jonathan B. Martin, Jaye E. Cable, Peter W. Swarzenski, Mary K. Lindenberg
2004, Ground Water (42) 1000-1010
Submarine ground water discharge is suggested to be an important pathway for contaminants from continents to coastal zones, but its significance depends on the volume of water and concentrations of contaminants that originate in continental aquifers. Ground water discharge to the Banana River Lagoon, Florida, was estimated by analyzing the...

Fausto Marincioni, Frances L. Lightsom, Rebecca L. Riall, Guthrie A. Linck, Thomas C. Aldrich, Michael J. Caruso
2004, Journal of Digital Information Management (2) 132-141
A pilot distributed geolibrary, the Marine Realms Information Bank (MRIB), was developed by the U.S. Geological Survey Coastal and Marine Geology Program and the Woods Hole Oceanographic Institution, to classify, integrate, and facilitate access to scientific information about oceans, coasts, and lakes. The MRIB is composed of a categorization scheme,...
Studying ground water under Delmarva coastal bays using electrical resistivity
Frank T. Manheim, David E. Krantz, John F. Bratton
2004, Ground Water (42) 1052-1068
Fresh ground water is widely distributed in subsurface sediments below the coastal bays of the Delmarva Peninsula (Delaware, Maryland, and Virginia). These conditions were revealed by nearly 300 km of streamer resistivity surveys, utilizing a towed multichannel cable system. Zones of high resistivity displayed by inversion modeling were confirmed by...

Devinder Mahajan, Phillip Servio, Keith W. Jones, Huan Feng, William J. Winters
C.E. Taylor, J.T. Kwwan, editor(s)
2004, Book chapter, Advances in study of gas hydrates
We have presented a summary of measurements on the physical properties of sediments relevant to methane hydrate recovery. The data includes not only geotechnical determinations, but also the CMT data that gives porosity values and pathways through the sediment material. The results show that CMT techniques can be used to...
Economic impacts of anthropogenic activities on coastlines of the United States
Orville T. Magoon, S. Jeffress Williams, Linda K. Lent, James A. Richmond, Donald D. Treadwell, Scott L. Douglass, Billy L. Edge, Lesley C. Ewing, Anthony P. Pratt
2004, Conference Paper, Coastal engineering 2004 : Proceedings of the 29th International Conference
Anthropogenic activities primarily impact coasts by reducing sediment inputs, altering sediment transport processes, and accelerating sediment losses to the offshore. These activities include: sand and gravel extraction, navigation and shore protection works; non-structural shoreline management strategies such as beach nourishment, sand by-passing and beach scraping, dams and flood control works;...
Comparison of fluorescence microscopy and solid-phase cytometry methods for counting bacteria in water
John T. Lisle, Martin A. Hamilton, Alan R. Willse, Gordon A. McFeters
2004, Applied and Environmental Microbiology (70) 5343-5348
Total direct counts of bacterial abundance are central in assessing the biomass and bacteriological quality of water in ecological and industrial applications. Several factors have been identified that contribute to the variability in bacterial abundance counts when using fluorescent microscopy, the most significant of which is retaining an adequate number...
Analysis of coral mucus as an improved medium for detection of enteric microbes and for determining patterns of sewage contamination in reef environments
Erin K. Lipp, Dale W. Griffin
2004, EcoHealth (1) 317-323
Traditional fecal indicator bacteria are often subject to a high degree of die-off and dilution in tropical marine waters, particularly in offshore areas such as coral reefs. Furthermore, these microbes are often not associated with human waste, and their presence may not be indicative of health risk. To address the...

2004, Ground Water (42) 1035-1051
The small bays along the Atlantic coast of the Delmarva Peninsula (Delaware, Maryland, and Virginia) are a valuable natural resource, and an asset for commerce and recreation. These coastal bays also are vulnerable to eutrophication from the input of excess nutrients derived from agriculture and other human activities in...

Where in the world are my field plots? Using GPS effectively in environmental field studies
Chris E. Johnson, Christopher C. Barton
2004, Frontiers in Ecology and the Environment (2) 475-482
Global positioning system (GPS) technology is rapidly replacing tape, compass, and traditional surveying instruments as the preferred tool for estimating the positions of environmental research sites. One important problem, however, is that it can be difficult to estimate the uncertainty of GPS-derived positions. Sources of error include various satellite- and...
Assessment of estuarine water-quality indicators using MODIS medium-resolution bands: initial results from Tampa Bay, FL
Chuanmin Hu, Zhiqiang Chen, Tonya D. Clayton, Peter W. Swarzenski, John Brock, Frank E. Muller-Karger
2004, Remote Sensing of Environment (93) 423-441
Using Tampa Bay, FL as an example, we explored the potential for using MODIS medium-resolution bands (250- and 500-m data at 469-, 555-, and 645-nm) for estuarine monitoring. Field surveys during 21–22 October 2003 showed that Tampa Bay has Case-II waters, in that for the salinity range of 24–32 psu,...
Holocene reef development where wave energy reduces accommodation
Eric E. Grossman, Charles H. Fletcher
2004, Journal of Sedimentary Research (74) 49-63
Analyses of 32 drill cores obtained from the windward reef of Kailua Bay, Oahu, Hawaii, indicate that high wave energy significantly reduced accommodation space for reef development in the Holocene and produced variable architecture because of the combined influence of sea-level history and wave exposure over a complex antecedent topography....

Dust storms and their impact on ocean and human health: dust in Earth's atmosphere
Dale W. Griffin, Christina A. Kellog
2004, EcoHealth (1) 284-295
Satellite imagery has greatly influenced our understanding of dust activity on a global scale. A number of different satellites such as NASA's Earth-Probe Total Ozone Mapping Spectrometer (TOMS) and Se-viewing Field-of-view Sensor (SeaWiFS) acquire daily global-scale data used to produce imagery for monitoring dust storm formation and movement....

A bootstrap approach to computing uncertainty in inferred oil and gas reserve estimates
Emil D. Attanasi, Timothy C. Coburn
2004, Natural Resources Research (13) 45-52
This study develops confidence intervals for estimates of inferred oil and gas reserves based on bootstrap procedures. Inferred reserves are expected additions to proved reserves in previously discovered conventional oil and gas fields. Estimates of inferred reserves accounted for 65% of the total oil and 34% of the total gas...

2004, Science (305) 827-829
The magnetic properties experiments are designed to help identify the magnetic minerals in the dust and rocks on Mars—and to determine whether liquid water was involved in the formation and alteration of these magnetic minerals. Almost all of the dust particles suspended in the martian atmosphere must contain ferrimagnetic minerals...
The role of the unsaturated zone in artificial recharge at San Gorgonio Pass, California
Alan L. Flint, Kevin M. Ellett
2004, Vadose Zone Journal (3) 763-774
The hydrogeology of the unsaturated zone plays a critical role in determining the suitability of a site for artificial recharge. Optimally, a suitable site has highly permeable soils, a capacity for horizontal flow at the aquifer boundary, a lack of impeding layers, and a thick unsaturated zone. The suitability of...
