Submarine groundwater discharge readings in semi-arid estuaries across the Texas coastal bend and associated water quality parameters obtained from 2014-09-29 to 2018-02-04

Submarine groundwater discharge (SGD) estimates via stationary time series measurements of radon-222 in Corpus Christi Bay (2014), Nueces Bay (2014-2016), Aransas-Copano Bays (2015), Copano Bay (2016), Baffin Bay (2016), and six stations from Aransas Bay to Baffin Bay (2017-2018). Associated porewater quality variables (temperature, pressure, dissolved oxygen, specific conductivity, salinity, pH) and nutrients (ammonium, nitrate, nitrite, nitrate+nitrite, dissolved inorganic nitrogen, phosphate, silicate, and dissolved organic carbon) were measured during sampling events. SGD-derived nutrient flux estimates are calculated as the product of Rn-222-derived SGD estimates and the porewater nutrient concentration.
