To estimate the CO2 flux for Galveston Bay, a subtropical estuary located in the northwestern Gulf of Mexico proximal to the Houston-Galveston metroplex, monthly cruises were conducted along a transect extending from the Houston ship channel to the mouth of Galveston Bay and Gulf of Mexico from October 2017 to September 2018. Surface samples were collected at each of five stations in the Bay and analyzed for chlorophyll-a. Chlorophyll-a concentrations varied spatially and temporally throughout the study period and were highest in the inner Bay in late winter (February) and at all stations in mid-spring (April), following the freshwater inflow event. Stations 4 and 5 (inner Bay, closest to the San Jacinto River mouth) had early peak chlorophyll-a concentrations in February of 2018 (39.9 and 63.3 µg L-1, respectively), whereas mid- and outermost sampling locations 1, 2, and 3 peaked in mid-April (28.2, 44.2, and 35.8 µg L-1, respectively). Slight increases in chlorophyll-a were observed at stations 4 and 5 in July and September of 2018. When compared with carbonate chemistry data, it appears that large freshwater inflows in late winter and early spring stimulated photosynthesis in the Bay, leading to an influx of atmospheric CO2.
