Technical Bulletins

This is a descriptive and comparative study of 17 lakes in Maine. The major objectives of this study are (1) to characterize the pelagial zone of the lakes physically, chemically, and biologically, (2) to assess bacterial pollution, (3) to compare the lakes to each other and classify them trophically, and (4) to compare the lakes to others in different geographic regions.


Modeling Sediment Movement In The Turbidity Maximum Of An Estuary, Allbert Kuo, Maynard M. Nichols, James Lewis Jan 1978

Modeling Sediment Movement In The Turbidity Maximum Of An Estuary, Allbert Kuo, Maynard M. Nichols, James Lewis

Books

This research developed a two-dimensional, time-dependent numerical model to simulate the movement of water and suspended sediment in the turbidity maximum of an estuary. This model is a systematic sequence of mathematical procedures derived from the mass-balance equation and the equation of motion. Lateral integration is used to obtain two-dimensional equations; these equations are integrated with depth over the height of successive layers. Finite difference equations then are written for each layer and solved numerically using prescribed boundary conditions.


Depuration Of Kepone By Atlantic Croaker In A Laboratory Study, Robert T. Doyle, J. V. Merriner, M. E. Bender Jan 1978

Depuration Of Kepone By Atlantic Croaker In A Laboratory Study, Robert T. Doyle, J. V. Merriner, M. E. Bender

VIMS Books and Book Chapters

Contamination of the James River in Virginia by the organochlorine pesticide Kepone R prompted depuration studies of commercially important species. Approximately 400 croaker (Micropogonias undulatus) were taken from the James River and placed in Kepone-free York River water. Groups of 20 fish, maintained at ambient temperature, were sampled over time to determine depuration rate. Results suggest that there is no substantial depuration of Kepone by croaker until water temperature exceeds 15 C.

Response And Recovery To Sediment Influx In The Rappahannock Estuary: A Summary, Maynard M. Nichols, Galen Thompson, Bruce Nelson Jan 1976

Response And Recovery To Sediment Influx In The Rappahannock Estuary: A Summary, Maynard M. Nichols, Galen Thompson, Bruce Nelson

VIMS Books and Book Chapters

Flooding from Tropical Stonn Agnes produced unique hydrographic conditions for transport and dispersal of sediment in the Rappahannock and .James estuaries. Analyses indicate two cycles of response and recovery to the shock of extreme freshwater and sediment influx; one cycle in response to Rappahannock inflow; the other to intense mixing within the estuary. Important stages in the sequence consist of: (1) an initial response and seaward surge of river water and sediment; (2) shock with downstream translation of the salt intrusion head with a near-bottom salinity front and high turbidity in surface and in bottom water; (3) rebound with intense …


The Effect Of Tropical Storm Agnes On Heavy Metal And Pesticide Residues In The Eastern Oyster From Southern Chesapeake Bay, M. E. Bender, R. J. Huggett Jan 1976

The Effect Of Tropical Storm Agnes On Heavy Metal And Pesticide Residues In The Eastern Oyster From Southern Chesapeake Bay, M. E. Bender, R. J. Huggett

VIMS Books and Book Chapters

The concentrations of cadmium, copper, and zinc in the eastern oyster, Crassostrea virginica, are compared for samples collected before and after Tropical Storm Agnes. The "before" samples consisted of 475 animals from 95 stations collected in January 1971 and the "after" samples of 285 animals from 57 stations collected in January 1973. Shifts in the areal concentrations distributions were observed, apparently due to Agnes. Analyses of hard clams, blue crabs and oysters for chlorinated hydrocarbon pesticides showed influx of these compounds to be minimal as reflected by the residue levels observed. Comparison of residue levels in oysters to pre-Agnes conditions …


Changes In Salinity Structure Of The James, York And Rappahannock Estuaries Resulting From The Effects Of Tropical Storm Agnes, Paul V. Hyer, Evon P. Ruzecki Jan 1976

Changes In Salinity Structure Of The James, York And Rappahannock Estuaries Resulting From The Effects Of Tropical Storm Agnes, Paul V. Hyer, Evon P. Ruzecki

VIMS Books and Book Chapters

The peak effect of the flood waters produced by Tropical Storm Agnes was seen on June 25 in the James, June 26 in the Rappahannock, and June 30 in the York. Recovery toward normal salinity conditions after the high runoffs proceeded discontinuously, with alternating periods of vertical stratification and destratification. During strongly stratified stages, saline water advanced upstream along the bottom. In the York and James Rivers, the most dramatic stratification occurred about July 20- 25. This event resulted in bottom salinity values exceeding normal ambient values and, at the river mouths, reaching values hitherto unobserved. This event was apparently …


The Effects Of The Agnes Flood On The Salinity Structure Of The Lower Chesapeake Bay And Contiguous Waters, A. Y. Kuo, E. P. Ruzecki, C. S. Fang Jan 1976

The Effects Of The Agnes Flood On The Salinity Structure Of The Lower Chesapeake Bay And Contiguous Waters, A. Y. Kuo, E. P. Ruzecki, C. S. Fang

VIMS Books and Book Chapters

The transient response of salinity distribution in lower Chesapeake Bay to flood waters from Tropical Storm Agnes is studied in terms of a two-layered, partially mixed estuary. Prior to 30 June 1972, surface salinities were well depressed throughout the Bay while those at the bottom near the Bay mouth were not depressed by 5 July. This resulted in a highly stratified situation normally found in the spring of the year. Stratification decreased when bottom waters were flushed down-bay by the flood (on 5 to 10 July for the region south of New Point Comfort). The "rebound" of salinity structure started …


The Effects Of Tropical Storm Agnes On The Copper And Zinc Budgets Of The Rappahannock River, Robert J. Huggett, Michael E. Bender Jan 1976

The Effects Of Tropical Storm Agnes On The Copper And Zinc Budgets Of The Rappahannock River, Robert J. Huggett, Michael E. Bender

VIMS Books and Book Chapters

The metals copper and zinc were analyzed in bottom sediments (top 1 cm) from the Rappahannock River before and after Tropical Storm Agnes. By extracting the sediments with various techniques (HN03, HCl) the nature of the metal speciation can be estimated. Data show that the inorganic copper was increased by a factor of 2 to 3 in the normally saline portion of the river as a result of Agnes but returned to before-Agnes levels within one year. Metal analyses of suspended sediments collected during the Agnes flooding allows an estimate of sedimentation indicating at least 7.5 mm of new sediments …


Flood Wave-Tide Wave Interaction On The James River During The Agnes Flood, John P. Jacobson, C. S. Fang Jan 1976

Flood Wave-Tide Wave Interaction On The James River During The Agnes Flood, John P. Jacobson, C. S. Fang

VIMS Books and Book Chapters

During the Agnes flood hourly tidal height data were collected at seven locations along the tidal James River and currents were measured at two transects in the lower James. A comparison between actual tides and currents and the predicted tidal features as given by the tide and tidal current tables of NOAA was made. Results of this comparison show that Agnes did significantly affect water levels in the upper portion of the tidal James, especially near Richmond. However in the lower portion of the James no discernible rise was evident due to the passage of the flood crest. A small …


Effects Of Tropical Storm Agnes On Nutrient Flux And Distribution In Lower Chesapeake Bay, C. L. Smith, W. G. Macintyre, C. A. Lake, J. G. Windsor Jr. Jan 1976

Effects Of Tropical Storm Agnes On Nutrient Flux And Distribution In Lower Chesapeake Bay, C. L. Smith, W. G. Macintyre, C. A. Lake, J. G. Windsor Jr.

VIMS Books and Book Chapters

Nutrient concentrations measured in lower Chesapeake Bay in the summer of 1972 immediately following the flooding associated with Tropical Storm Agnes are compared with those in the summer of 1973, a season of more normal rainfall. The large amount of land runoff produced unseasonably high concentrations of dissolved inorganic nitrogen in the Bay near the mouth of the Potomac River. Phosphate concentrations were essentially unaffected by the flooding. Fluxes of total nitrogen and total phosphorus nutrients through the mouth of Chesapeake Bay were calculated for both summers. The calculated net export of nutrients from the Bay in both August 1972, …


Observations On Dissolved Oxygen Conditions In Three Virginia Estuaries After Tropical Storm Agnes (Summer 1972), R.A. Jordan Jan 1976

Observations On Dissolved Oxygen Conditions In Three Virginia Estuaries After Tropical Storm Agnes (Summer 1972), R.A. Jordan

VIMS Books and Book Chapters

Dissolved oxygen (DO) and salinity levels in the James, York, and Rappahannock estuaries were monitored for approximately two months (June 24-August 31, 1972) following Tropical Storm Agnes. DO depressions developed more rapidly and were more severe in the deep waters of the York and Rappahannock than in the James. Depressions that developed immediately after the storm were followed by recoveries and subsequent, more severe depressions. In late July, bottom water DO concentrations below 1 mg/1 were found at stations covering 15 miles of the York and 25 miles of the Rappahannock. Comparison of river data with Chesapeake Bay data suggests …


The Effect Of Tropical Storm Agnes As Reflected In Chlorophyll A And Heterotrophic Potential Of The Lower Chesapeake Bay, Paul L. Zubkoff, J. Ernest Warriner Iii Jan 1976

The Effect Of Tropical Storm Agnes As Reflected In Chlorophyll A And Heterotrophic Potential Of The Lower Chesapeake Bay, Paul L. Zubkoff, J. Ernest Warriner Iii

VIMS Books and Book Chapters

A hydrographic station (Station Y) at the mouth of the York River (37°14.6'N, 76°23.4'W) was under biological surveillance for one year prior to the arrival of Tropical Storm Agnes. For one full year following this storm, these measurements were continued. In addition, the chlorophyll a and heterotrophic potential measurements were incorporated into an ongoing zooplankton sampling program of the lower Chesapeake Bay below 37°40'N latitude.


Public Health Aspects Of Tropical Storm Agnes In Virginia's Portion Of Chesapeake Bay And Its Tributaries, M. P. Lynch, J. Claiborne Jones Jan 1976

Public Health Aspects Of Tropical Storm Agnes In Virginia's Portion Of Chesapeake Bay And Its Tributaries, M. P. Lynch, J. Claiborne Jones

VIMS Books and Book Chapters

All Virginia waters within Chesapeake Bay were closed for the taking of shellfish for direct consumption on 23 June 1972. This initial closing was in anticipation of high microorganism levels accompanying flood waters moving downstream. Various areas beginning with the lower portion of Chesapeake Bay were reopened beginning )n 20 July 1972. By 5 October 1972 all areas closed as a result )f Tropical Storm Agnes were reopened. No increased incidents of infectious diseases caused by waterborne microorganisms were noted in Virginia which could be attributed to Tropical Storm Agnes.


Methods For Measuring Ecosystem Stress, R. J. Huggett, M. E. Bender Jan 1976

Methods For Measuring Ecosystem Stress, R. J. Huggett, M. E. Bender

VIMS Books and Book Chapters

If one looks back over the past twenty-five years, at the pollution crises which have made the headlines and influenced our decision making policies on both local and national levels, one may note a very interesting aspect. That is, the crises are often associated with the development of new and more sensitive types of analytical instrumentation. Several examples of this readily come to mind: for example, it wasn't until the development of electron capture detection for gas chromatography that DDT really became a crisis. The reason is quite simple: the concentrations which were being accumulated by the organisms were below …
