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 …

Composition Of Arkansas Grapes During Maturation, Cameron Jones, Dominic T.C. Yang, Thomas O. Whitley Jan 1976

Composition Of Arkansas Grapes During Maturation, Cameron Jones, Dominic T.C. Yang, Thomas O. Whitley

Journal of the Arkansas Academy of Science

Changes in organic acid and glucose content during maturation and ripening of grapes grown in Arkansas in 1973 are shown for four French hybrid varieties, S5279, S10878, SV23- 657, and S13053, and for four rotundifolia varieties, Scuppernong, Tarheel, Fry, and Magoon. In all varieties the concentrations of malates and tartrates were highest in the early stages of berry growth after veraison. During ripening the titratable acidity decreased and Balling and pH measurements increased. Although varieties reached maturity on different dates, changes in parameters followed similar curves typical for grapes of the species but occurring over a short period (Johnson and …


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.

Oyster Spatfall On Shellstrings In Virginia Rivers: 1975 Annual Summary, Dexter S. Haven, Paul C. Kendall Jan 1976

Oyster Spatfall On Shellstrings In Virginia Rivers: 1975 Annual Summary, Dexter S. Haven, Paul C. Kendall

Reports

The Virginia Institute of Marine Science (VIMS) conducts weekly surveys from June through early October to obtain oyster spatfall information. Spat counts are made from oyster shells strung on wire and · suspended from stakes on public and private beds. The number of spat on shells are counted each week of the spawning season to determine the potential of a particular area for receiving a strike and to predict the most likely period the strikes will occur. Shells .planted just before the period of maximum set have the best chance of getting a good strike.

Comparison Of Economic Returns From Grain Crops, H M. Fisher Jan 1976

Comparison Of Economic Returns From Grain Crops, H M. Fisher

Journal of the Department of Agriculture, Western Australia, Series 4

While wheat is still generally the most profitable crop in Western Australia the relative profitability of barley and linseed has risen in the last few years; in southern areas they are likely to be at least as profitable as wheat.

Oats has fallen in profitability relative to wheat, and grain legumes have suffered a marked fall. Yields of these grains have increased with the introduction of new varieties but their price increases have not kept pace with those of wheat and barley. The present relationship of yields and costs indicates that substantial price changes will be needed to change the …


A Comparison Of Hay Conservation Systems, E E. Rowley Jan 1976

A Comparison Of Hay Conservation Systems, E E. Rowley

Journal of the Department of Agriculture, Western Australia, Series 4

The high cost an dshortage of farm labour in the Esperance District is posing serious problems for farmers using traditional hay conservation systems. Author Ted Rowley, then an advisor with the Esperance District office of the Department of Agriculture surveyed a number of farms to study the economics of varoius alternatives. This article is a summary of his report presented to a 1976 Fodder Conservation Workshop.
