Dissolved inorganic carbon and total alkalinity fluxes from sediment incubation experiments during four R/V Pelican cruises to the Louisiana shelf in 2017 and 2018

Abstract

These data include the measurements of dissolved inorganic carbon (DIC) and total alkalinity (TA) fluxes from sediment incubation experiments at several sites on the Louisiana shelf. Data were collected during four cruises in 2017 and 2018. Cruises were conducted aboard the R/V Pelican in April (PE17-18), July (PE18-02), and September-October (PE18-11) of 2017 and January of 2018 (PE18-19). The study domain included the Louisiana and Texas continental shelf from the Mississippi River Bird's Foot delta to south of Galveston Bay. The objective of this work was to quantify how hurricanes and tropical storms affect metabolic rates and the concentrations of oxygen and DIC/pH. These data assess the sediment metabolism response before and after Hurricane Harvey and were collected by Dr. John Lehrter of the University of South Alabama.
