Albemarle-Pamlico Sounds
Water-Quality Trends and Basin Activities and Characteristics for the Albemarle-Pamlico
Estuarine System, North Carolina and Virginia
Type: Condition
of habitat and sources affecting habitat (i.e., the condition or functionality
of the habitat).
Category: Submerged and Intertidal
Cost: Information not provided.
Description: The project summarizes land-use/land-cover data, geographic
descriptions, flow characteristics and water quality data. Non-parametric trend
analyses were performed on water quality data using the Seasonal Kendall test.
Correlation analyses were performed on many water quality parameters including
DO, pH, suspended solids, salinity, ammonia, nitrogen, phosphorous, soluble
nutrients and chlorophyll a, as well as on more than 50 basin characteristics
and activities.
Outcome: Several general, system-wide correlations were determined; (1)
dissolved oxygen generally increased; (2) pH generally increased; (3) suspended
solids, in general, decreased; and (4) chlorophyll a increased. Trends in concentrations
of nutrients were very site-specific.
