Plant Geography And Water Quality Data For Chesapeake Bay Waters Of Virginia's Eastern Shore, John C. Munday Jr., Paul L. Zubkoff, J. Ernest Warinner Iii, Elvira Ferrez-Reyes, Hayden H. Gordon, Kenneth A. Moore Sep 1978

Plant Geography And Water Quality Data For Chesapeake Bay Waters Of Virginia's Eastern Shore, John C. Munday Jr., Paul L. Zubkoff, J. Ernest Warinner Iii, Elvira Ferrez-Reyes, Hayden H. Gordon, Kenneth A. Moore

Reports

Plant geography and water quality data were collected in shallow water near Cape Charles and Occohannock Creek, Virginia on two occasions. Data from April, 1978 included hydrography, distribution and abundance of -submerged aquatic vegetation, phytoplankton census, and water clarity data. Data from May, 1978 included hydrography, phytoplankton census, water clarity, and primary productivity data. The May data collection was coincident with an overflight of the NASA JSC C-130 aircraft (6600 m) acquiring color infrared photography and multispectral scanner data; cell concentrations reached 105/ml, chlorophyll~ 72 pg/1, and suspended sediment 94 mg/1. i

Zooplankton Distribution, Biomass, Biochemical Composition And Seasonal Community Structure In Lower Chesapeake Bay, Fred Jacobs Jan 1978

Zooplankton Distribution, Biomass, Biochemical Composition And Seasonal Community Structure In Lower Chesapeake Bay, Fred Jacobs

Dissertations, Theses, and Masters Projects

Zooplankton composition, distribution, biomass and biochemical constituents were determined monthly in the lower Chesapeake Bay for two years beginning in August 1971. Settled volume, dry weight, and ash-free dry weight estimates of total biomass were generally consistent in showing summer and late winter peaks. A mean dry weight peak of 258 mg/m3 in August 1971 decreased precipitously to a December low of 9 mg/m3, then increased to a March 1972 peak of 199 mg/m3. The second year mirrored this pattern, except that the passage of Tropical Storm Agnes in June 1972 lowered the summer peak values for July and August …
