ARELLANO TORRES, ELSA

My primary research interests are the documentation and study of Quaternary climate changes registered in coastal and marine sediments using planktonic and benthic foraminifera, geochemical proxies, and time-series analyses. I have worked with marine sediment-cores from the Eastern Tropical Pacific, the Gulf of Mexico, and the Caribbean Sea, to reconstruct changes in the surface ocean, marine productivity, oxygenation, subsurface denitrification, and intermediate circulation at different temporal scales: secular, millennial and glacial-interglacial. One of my project goals aims to reconstruct ocean processes and connections between terrestrial and marine inputs to the sediments. I am currently working on Holocene-Pleistocene paleoceanography in the Gulf of Mexico and collaborating with projects on sandy beaches, coastal lagoons and cores along the NW Mexican Pacific.
