Weekly surface water quality measurements in Narragansett Bay from 1959-2019

Abstract

The Narragansett Bay Long-Term Plankton Time Series is one of the world's longest-running plankton surveys. Beginning in 1959, weekly samples have been collected to assess phytoplankton biomass with chlorophyll a and to characterize the chemical and physical parameters of Narragansett Bay (i.e., water temperature, salinity, chlorophyll a, silicate, phosphate, ammonium, nitrate/nitrite, water clarity, and light). Samples are collected once per week - regardless of tidal stage - for temperature, salinity, turbidity, chlorophyll a, and nutrients. This dataset provides weekly discrete surface concentrations for all parameters from 1959-2019 with support from the University of Rhode Island by the U.S. Department of Fish and Wildlife.
