The Photoelectric Effect In External Eields, Christian Bracher, John B. Delos, Vassiliki Kanellopoulos, Manfred Kleber, Tobias Kramer

Arts & Sciences Articles

Atoms and negative ions interacting with laser photons yield a coherent source of photoelectrons. Applying external fields to photoelectrons gives rise to interesting and valuable interference phenomena. We analyze the spatial distribution of the photocurrent using elementary quantum methods. The photoelectric effect is shown to be an interesting example for the use of coherent particle sources in quantum mechanics.

Hyperpycnal Discharge Of Fluvial Sediment To The Ocean: Impact Of Super‐Typhoon Herb (1996) On Taiwanese Rivers, John D. Milliman, Shuh-Ji Kao

VIMS Articles

Hyperpycnal events (when suspended sediment concentrations exceed 40 g/L) occur in small‐ and medium‐sized rivers throughout the world but are particularly common in Taiwan; they are often related to landslides or debris flows initiated and transported by typhoon floods. Super‐Typhoon Herb, which swept across Taiwan on July 31–August 2, 1996, triggered floods and landslides throughout the southern part of the island. Sediment concentrations in at least seven rivers (Taan, Choshui, Pachang, Erhjen, Tsengwen, Kaoping, and Peinan) approached or exceeded 40 g/L. Calculated sediment discharged from nine rivers (these seven as well as the Wu and Houlung, neither of which apparently …

Estimating Relative Abundance Of Young Of Year American Eel, Anguilla Rostrata, In The Virginia Tributaries Of Chesapeake Bay (Spring 2004 Survey), Marcel M. Montane, Wendy A. Lowery, Hank Brooks, Aimee D. Halvorson

Reports

The Atlantic States Marine Fisheries Commission (ASMFC) adopted the Interstate Fishery Management Plan (hereafter referred to as FMP) for the American eel in November 4 1999. The FMP focuses on increasing coastal states’ efforts to collect American eel data through both fishery dependent and fishery independent studies. Consequently, member jurisdictions (including Virginia) agreed to implement an annual survey for young of year (YOY) American eels. The survey is intended to “…characterize trends in annual recruitment of the young of year eels over time [to produce a] qualitative appraisal of the annual recruitment of American eel to the U.S. Atlantic Coast” …

Effects Of Sunlight On Decomposition Of Estuarine Dissolved Organic C, N And P And Bacterial Metabolism, Sl Mccallister, Je Bauer, J Kelly, Hw Ducklow

VIMS Articles

The effects of natural sunlight and microbial decomposition on DOC, DON, and DOP were investigated along the salinity gradient of a temperate coastal plain estuary. The impact of sunlight-irradiated DOM on bacterial properties (bacterial abundance, production, bacterial growth efficiency [BGE]) was also followed. Surface-water light levels resulted in no detectable abiotic production of NH4+ or PO43- or loss of DOC. Bacterial decomposition of DOC was enhanced by 27 to 200 % in irradiated relative to dark treatments. There was, however, no corresponding enhancement in DON and DOP remineralization. Significant differences in bacterial decomposition of light-exposed DOC were frequently observed following …

Radionuclide And Biomarker Proxies Of Past Ocean Circulation And Productivity In The Arabian Sea, A Pourmand, F Marcantonio, Ts Bianchi, Elizabeth A. Canuel, Ej Waterson

VIMS Articles

We present new excess Pa-231/Th-230 activity ratios and lipid biomarker results from northeastern Arabian Sea sediments (core 93KL) spanning the past 50 ka in an effort to constrain further the relationship between climate at low and high latitudes. Pa-231/Th-230 activity ratios are maintained at values significantly higher than the water-column production ratio of 0.093. Average Pa-231/Th-230 activity ratios are lower during the last glacial period than during the Holocene. The lowest Pa-231/Th-230 activity ratios coincide with the timing of Heinrich Events 1-5. Profiles of lipid biomarker fluxes and Pa-231/Th-230 activity ratios from 32 to 12 ka show similar patterns, suggesting …

Chesapeake Bay Dune Systems: Monitoring, Donna A. Milligan, C. Scott Hardaway Jr., George R. Thomas, Lyle M. Varnell, Thomas A. Barnard, William G. Reay, Travis R. Comer, Christine A. Wilcox

Reports

This project is aimed at developing an understanding of detailed beach and dune change. During the course of this monitoring, Hurricane Isabel impacted the coastal plain of Virginia and significantly altered almost all Bay shorelines to one degree or another in September 2003. This is particularly true of shorelines facing north, east, and south since the winds shifted as the storm passed. This event provided an opportunity to measure the changes to natural dune systems around the Bay due to the storm as well as their recovery after the event.

Interagency Shoreline Management Consensus Document, Center For Coastal Resources Management, Virginia Institute Of Marine Science

Reports

There are concerns in the general public and regulatory and environmental advisory agencies regarding the apparent inconsistent and /or contradictory guidance offered to property owners regarding shoreline management in Virginia. There has been a growing interest among the agencies that manage, or otherwise have a role in shoreline management, to develop a Virginia perspective on the issue. This project to develop a consensus position from a VIMS perspective, with funding from the Virginia Coastal Program, may serve as the initiation of an effort to develop consensus guidance on shoreline management that integrates the issues and concerns extant in the various …

Reports

The Chesapeake Bay Breakwater Database is being developed by personnel in the Virginia Institute of Marine Science’s (VIMS) Shoreline Studies Program for the U.S. Army Corps of Engineers (COE) in order to:

1) document breakwater system performance around Chesapeake Bay relative to predictions

2) develop guidelines for breakwaters in sand limited and fetch limited systems such as estuaries, reservoirs, lakes and bays.

Monitoring Relative Abundance Of American Shad In Virginia Rivers 2004 Annual Report, John E. Olney

Reports

Concern about the decline in landings of American shad (Alosa sapidissima) along the Atlantic coast prompted the development of an interstate fisheries management plan (FMP) under the auspices of the Atlantic States Marine Fisheries Management Program (ASMFC 1999). Legislation enables imposition of federal sanctions on fishing in those states that fail to comply with the FMP. To be in compliance, coastal states are required to implement and maintain fishery-dependent and fishery-independent monitoring programs as specified by the FMP. For Virginia, these requirements include spawning stock assessments, the collection of biological data on the spawning run (e.g., age-structure, sex ratio, and …

Input Of Particulate Organic And Dissolved Inorganic Carbon From The Amazon To The Atlantic Ocean, Erm Druffel, Je Bauer, S Griffin

VIMS Articles

We report concentrations and isotope measurements (radiocarbon and stable carbon) of dissolved inorganic carbon (DIC) and suspended particulate organic carbon (POC) in waters collected from the mouth of the Amazon River and the North Brazil Current. Samples were collected in November 1991, when the Amazon hydrograph was at its annual minimum and the North Brazil Current had retroflected into the equatorial North Atlantic. The DIC D 14 C results revealed postbomb carbon in river and ocean waters, with slightly higher values at the river mouth. The low DIC delta(13)C signature of the river end-member (-11%) demonstrates that about half of …

Status Of The Major Oyster Diseases In Virginia 2004 A Summary Of The Annual Monitoring Program, Ryan Carnegie, Eugene M. Burreson

Reports

2004 was the second very wet year in a row. While rainfall and streamflows were normal in winter and early spring, and just slightly above average during the summer, the fall of 2004 was nearly as wet as the year before. Salinities were again depressed throughout the lower Bay. Water temperatures were below normal during the winter, but typical otherwise. Low salinities and, in the winter, temperatures brought continued abatement in the oyster diseases caused by Perkinsus marinus (Dermo) and Haplosporidium nelsoni (MSX). Among quarterly James River Survey sites, maximum annual P. marinus prevalences were the lowest they had been …

Convenient Synthesis Of Copper (I) Thiolates And Related Compounds, Lynda M. Nguyen, Megan E. Dellinger, Jeffrey T. Lee, Ronald A. Quinlan, Arnold L. Rheingold, Robert D. Pike

Arts & Sciences Articles

The addition of phosphine ligands to several of the products is demonstrated, and the crystal structure of [Cu2(MBT)2(DPPE)3] · Et2O (MBT = 2-mercaptobenzothiazolate, DPPE = 1,2-bis(diphenylphosphino)ethane) is reported.

An Unprecedented Scientific Community Response To An Unprecedented Event: Tropical Storm Agnes And The Chesapeake Bay, M. P. Lynch

VIMS Books and Book Chapters

In June 1972, the remnants of Hurricane Agnes brought destructive floods to the watershed of the Chesapeake Bay basin. Unlike Hurricane Isabel, Agnes did not strike Chesapeake Bay directly, but deposited a record amount of rainfall on the watershed. The evening that the Agnes rainfall began in earnest coincided with a meeting of the Citizens Program for the Chesapeake Bay. The directors of the three largest Chesapeake Bay research institutions, Drs. Donald W. Pritchard, L. Eugene Cronin, and William J. Hargis Jr., were in attendance at this meeting. The potential magnitude of the Agnes rainfall was readily apparent at the …

Isabel's Silent Partners: Seasonal And Secular Sea Level Change, J. D. Boon

VIMS Books and Book Chapters

Tidal conditions fail to explain a paradoxical similarity in water level extremes induced by Hurricane Isabel on 18 September 2003, and the 23 August 1933 storm of record at Hampton Roads, Virginia. Storm surge peaks occurred near astronomical high tide during both storms, but Isabel arrived during neap tides while tides during the 1933 storm were nearer to spring. In addition, Isabel produced a lesser storm surge, yet she yielded a storm tide, or high-water mark, roughly equal to that of the 1933 hurricane. The answer to the paradox lies in observed sea level—water level measured relative to the land—and …

What Has Been Learned About Storm Surge Dynamics From Hurricane Isabel Model Simulation?, Harry V. Wang, J. Cho, Jian Shen, Y. P. Wang

VIMS Books and Book Chapters

An unstructured grid hydrodynamic model was used to study storm surge in the Chesapeake Bay during Hurricane Isabel. The model-simulated, storm-induced water level compared reasonably well with the measured data collected around the Bay. Calibrated water level was extracted from the model to further analyze the dynamics of the surge as it formed and propagated along the mainstem Chesapeake. Based on time-series analysis, formation of the surge due to the pumping of coastal waters (hereafter called the primary surge) into the Chesapeake was first identified at the Bay mouth with a peak height of 1.5 m above mean sea level …

Predicting Future Shoreline Condition Based On Land Use Trends, Logistic Regression, And Fuzzy Logic, Lynne M. Dingerson

Dissertations, Theses, and Masters Projects

The lower Chesapeake Bay and adjacent coastal waters serve as the primary summer nursery areas for juvenile sandbar sharks (Carcharhinus plumbeus) in the Northwest Atlantic Ocean. The large population of juvenile sandbar sharks in this ecosystem benefits from increased food availability that fuels rapid growth and from limited exposure to large shark predators. Juvenile growth and survival is the most critical life history stage for sandbar sharks, and juvenile nursery grounds will continue to play an important role in the slow recovery of this stock from severe population declines due to overfishing. The goal of this study was to assess …
