Summary geochemistry and radiotracer rates for 30 marine sediment cores covering eight sites and four geochemical regimes

<p>This dataset contains porewater geochemistry and rate data obtained from Gulf of Mexico sediments collected using both push core and multiple core technology. Sediment push cores were collected across multiple dives of HOV Alvin, during cruises AT18-02 (2010) and AT26-13 (2014) aboard the R/V Atlantis. Multiple cores were collected during cruises EN527, EN528, EN529, and EN586 aboard the R/V Endeavor. Procedures for sample processing were identical for both types of cores.</p>
