Radiocarbon Dates and Foraminiferal Geochemistry Data for Sediment Core Collected from Garrison Basin, Gulf of Mexico
August 25, 2021
Stable oxygen and carbon isotope composition (delta18O and delta13C) 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 sediment core 2010-GB2-GC1 collected from the Garrison Basin (26.67 degrees N, 93.92 degrees W) 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 (delta18Osw; 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).

Holocene evolution of sea-surface temperature and salinity in the Gulf of Mexico
Flows into and out of the Gulf of Mexico (GoM) are integral to North Atlantic ocean circulation, and help facilitate poleward heat transport in the Western Hemisphere. The GoM also serves as a key source of moisture for much of North America. Modern patterns of sea-surface temperature (SST) and salinity in the GoM are influenced by the Loop Current, its eddy-shedding dynamics, and the...
