The Patuxent River estuary was investigated over a 25-hour tidal cycle
from October 17-18, 1972, during the Patuxent River Cooperative Study
(conducted by the University of Maryland). These data were collected as
part of a joint investigation by the University of Maryland's Center for
Environmental and Estuarine Studies (Chesapeake Biological Lab) and the
Institute for Fluid Dynamics and Applied Mathematics (College Park,
Maryland). The resulting chemical, physical, and biological data were
assembled into a format that could be utilized by investigators,
collectively titled the Patuxent River Data Bank.
The Patuxent River Data Bank was submitted to NODC on a 9-track, 1600
BPI tape in EBCDIC and contains headers and one data file.
Heat concentration (in kilocalories/liter) and instantaneous flux
magnitude (in megacalories/square meter/second) were recorded over the
tidal cycle. Other data associated with this study are filed under NODC
Reference #'s L01574 and L01576; all data are in the Level-A directory
under L01574.001.
Data associated with marine chemistry include: Dissolved organic carbon
(milligrams/liter), Particulate carbon (milligrams/liter), salts
(grams/liter), Dissolved oxygen (milligrams/liter), and total
particulates (milligrams/liter). Instantaneous flux magnitudes for
carbon were measured in grams/liter; for salts, in kilograms/liter; for
oxygen, in milligrams/liter; and for total particulates,
milligrams/liter.
Parameters associated with primary productivity (L505) include: Nitrate
+Nitrite conc., Ammonia Nitrogen conc., Total Kjeldahl Nitrogen, Organic
Phosphate conc., Total Hydrolyzable Phosphate, Active Chlorophyll-a, and
Total Chlorophyll. Nutrients were measured in milligrams/liter;
chlorophyll concentrations were measured in micrograms/liter.
Instantaneous flux magnitudes were measured in milligrams/square
meter/second.
Additional data collected during this investigation are filed under NODC
Reference #'s L01575 and one tape of Patuxent River Estuary Hydro data
