Water-quality measurements were made at six sites in or near North Carolina?s Pamlico River estuary and at five sites in or near the Neuse River estuary. Measurements taken at 15-minute intervals included near-surface and near-bottom specific conductance; near-surface water temperature; and near-surface, mid-depth, and near-bottom dissolved-oxygen concentrations.
In the Pamlico River estuary, salinities generally ranged from less than 0.1 to 20 parts per thousand during the period October 1991 through September 1992. Recorded water temperatures in the Pamlico River were between 3.5 and 33 degrees Celsius during the measurement period. Dissolved-oxygen concentrations ranged from less than 1 to 23 milligrams per liter.
In the Neuse River estuary, salinities ranged from 0.3 to 27 parts per thousand between October 1991 and September 1992. During the same period, recorded water temperatures in this estuary were between 4 and 34 degrees Celsius. Dissolved-oxygen concentrations ranged from less than 1 to greater than 22 milligrams per liter.
Daily mean values of salinity; water temperature; dissolved-oxygen concentrations; and dissolved oxygen, percent saturation, are presented in tables and graphs. Five-day mean values of water temperature and dissolved-oxygen concentrations for day and night conditions also are presented in tables. Data are presented illustrating the vertical distribution of selected constituents at each site for selected dates.
