Abstract

The Ecosystem Science and Modeling lab has been collecting water samples from five stations in the Mission-Aransas Estuary (MAE, Northwest Gulf of Mexico, Texas coast) for carbonate system characterization on a monthly to twice monthly basis since May 2014. This dataset includes temperature, salinity, dissolved inorganic carbon (DIC), total alkalinity (TA), calcium, and pH measurements from surface and bottom water samples in MAE from May 2014 – Feb 2017 and Dec 2018 – Feb 2020. Additional data ...

Samples were collected every two weeks (March-October) or monthly (November-February) using Mission-Aransas National Estuarine Research Reserve Small Boat.  Water samples from both the surface (~0.5 meters) and the bottom of the water column (within 0.5 m from the sediment-water interface) were obtained using a Van Dorn water sampler.
