Abstract:

This dataset contains surface water quality data obtained from Mississippi Sound from 2021-06-02 to 2021-09-29. Surface water quality data including chlorophyll a, phycocyanin, phycoerythrin, colored dissolved organic matter (CDOM), turbidity at 595 nm, turbidity at 700 nm, salinity, temperature, pH, dissolved oxygen, partial pressure of carbon dioxide, backscattering at 470 nm, backscattering at 532 nm, and backscattering at 650 nm was measured by an autonomous surface vessel (SP-48 from Seatrac systems Inc.).

Purpose:

To characterize water quality and develop remote sensing algorithms.

Data Parameters and Units:

The headers are No., Sample Site, Site Names, Latitude (decimal degrees), Longitude (decimal degrees), Date (mm/dd/yyyy), Chl-a (µg/L), PC (ppb), PE (ppb), CDOM (ppb), Turbidity_595nm (NTU), Turbidity_700nm (NTU), Salinity (PSU), Temperature (°C), pH, DO (mg/L), pCO2 (ppm), bb_470nm (m-1sr-1), bb_532nm (m-1sr-1), and bb_650nm (m-1sr-1). bb measurements are backscattering measurements that are used in remote sensing algorithm development.

Methods:

Surface water quality data was collected by the autonomous surface vessel.
