Abstract

This dataset includes nutrient data from R/V Hugh R. Sharp cruise HRS2110 in the Chesapeake Bay during August 2021.

Cite Dataset

Water samples were collected using a 12 x 10-liter Niskin bottle rosette sampler equipped with a conductivity, temperature, and pressure instrument package (SBE9, Sea-Bird Electronics, Bellevue, Washington, U.S.A.), a sensor for dissolved oxygen (SBE43, Sea-Bird), and a sensor for chlorophyll fluorescence (FluoroWetlabECO, AFL FL Sensor). NH4, NO2, and urea were measured on board immediately after sample collection. NO3 was assayed in the home laboratory on samples stored frozen at the time of collection.
