Data Summaries Dissolved Oxygen Nutrients Trend analysis

Nutrient Plots

The following movies were created from plots of data of various nutrients, analyzed from water samples collected from the Neuse River. Sampling trips are conducted bi-weekly, but may be conducted more frequentlly in the event of episodic algal blooms and storm events.

Water samples are analyzed for the following parameters:

  • Total Suspended Solids
  • Total Phosphorus
  • Soluble Reactive
  • TKN- total kjeldahl nitrogen
  • NH4- ammonium
  • Nitrate
  • Urea
  • Amino Acids
  • Silica
  • Chlorophyll a
  • Phytoplankton

Various water sampling bottles used for nutrient sample collection.

Samples are held on ice to preserve them for the trip back to the lab, where they are kept in huge walk in freezers.

The following examples show the plotted portion of the Neuse River between New Bern and Cherry Point, for various nutrients.
