    "descript": "Stable oxygen and carbon isotope composition (\u03b418O and \u03b413C) and magnesium-to-calcium (Mg\/Ca) ratios were measured in the tests of planktic foraminiferal species, Globigerinoides ruber (white variety), in a northwestern Gulf of Mexico (GoM) sediment core 2010-GB2-GC1 collected from the Garrison Basin (26.67\u00b0N, 93.92\u00b0W) at a water depth of 1776 meters (m), aboard the R\/V Cape Hatteras in April 2010.  These measurements are used to generate sub-centennial-scale reconstructions of sea surface temperature (SST) and the stable oxygen isotope composition of seawater (\u03b418Osw; a proxy for changes in salinity) over the past 11,700 years. For further information regarding data collection and\/or processing methods, refer to the associated journal article (Thirumalai and others, 2021).",
