<div><p>Data were collected on three cruises on the Brazos River Plume in the Northern Gulf of Mexico. Cores were collected from: 11 stations on September 10, 2017; 23 stations on October 29, 2017; and 26 stations on July 12, 2018. The September 2017 cruise was conducted on R/V Pelican (PE18-09); the two subsequent cruises were conducted on R/V Trident.</p>
<p>On each cruise, a series of box cores were collected in a grid pattern. From those box cores, a series of sub-cores were collected. Those included: x-radiograph trays, a 3-inch aluminum and/or polycarbonate core, and a 6-inch core. They were stored in a refrigerator at 2 °C and later split into 1 cm sections, x-rayed, and stored in bags until further analysis.</p>
<p>To collect water content, a basic oven was used at 60 °C. They were dried in pre-weighed aluminum tins, and then the water content was calculated after weighing the dry weight.</p>
<p>The grain size was processed in a Malvern Mastersizer 2000 that uses laser diffraction to analyze the grains.</p>
<p>The Mercury content was analyzed in a Milestone DMA-80 that combusts the sample to get a total mercury content.</p></div>
Brazos Plume Core Data
<div><p>This dataset contains core data collected in the Brazos River Plume, TX during three cruises conducted in 2017 and 2018. Cores were analyzed for grain size and mercury content. The sample collection that took place on September 10, 2017 was supported by NSF award OCE-1635893. Award OCE-1829221 supported the rest of the data collection.</p></div>
Brazos Plume Core Data
<div><p>Data Processing: Most of the data were processed in Excel, Matlab R2020a, or ArcPro 2.6.3. The data were stored in Excel sheets, then graphs and maps were created using Matlab or ArcPro.</p>
<p>BCO-DMO Processing:<br />
- concatenated three separate data files into one dataset;<br />
- added Date column;<br />
- re-named fields to conform with BCO-DMO naming conventions (replaced spaces with underscores);<br />
- rounded Hg_Content and Water_Content columns.</p></div>
