Sampling Program

Trawling surveys:
Water quality and fish are sampled in each site once each month.

In the Neuse River a random subsample of 40 stations are chosen in each of the lower and upper river sites

Upper Neuse River Stations:
    Upper Neuse River Stations

Lower Neuse River Stations:
    Lower Neuse River Stations

Sampling consists of vertical profiles of environmental conditions in the water column at each station and a short trawl to quantify fish distribution and assemblages. We also have been collecting zooplankton samples at select stations to compare with historical data sets.

In the Pamlico Sound, sampling consists of vertical profiles of environmental conditions in the water column at 70 fixed stations

Pamlico stations

Water is collected (at the surface and bottom) at 14 stations, filtered, and measured for chla concentration. At 26 of the stations short trawls are used to collect fish. (Latest Results = Pamlico maps)

River-wide Hydrolab surveys:
Each month we map 17 lateral transects across the Neuse River estuary

Whole river survey

    Vertical profiles of environmental variables (temperature, salinity, dissolved oxygen) are recorded using a HydroLab DataSonde. Bottom measurements are then interpolated in ArcView Spatial Analyst using the inverse distance weighting subroutine. (Latest Results = Neuse maps).
