Jessica Jacobs

Jessica uses subfossil coral skeleton to study changes in sea-surface temperature over the Holocene. Her research aims to better constrain natural climate variability to help predict what future climate may look like in the tropics and subtropics.

During my time with the USGS I have focused on ecosystem change in coastal environments. I have experience with benthic foraminifera indentification, geochemical analyses using ICP-OES and a Picarro water isotope analyzer, and microsampling of modern and subfossil coral cores. Prior to the USGS, I conducted environmental monitoring in southeast Florida with a focus on surface and groundwater.

Science and Products

Identifying and constraining marsh-type transitions in response to increasing erosion over the past century

Marsh environments, characterized by their flora and fauna, change laterally in response to shoreline erosion, water levels and inundation, and anthropogenic activities. The Grand Bay coastal system (USA) has undergone multiple large-scale geomorphic and hydrologic changes resulting in altered sediment supply, depositional patterns, and degraded barrier islands, leaving wetland salt marshes vulner

Sediment Core Microfossil Data Collected from the Coastal Marsh of Grand Bay National Estuarine Research Reserve, Mississippi, USA

To aid in geologic studies of sediment transport and environmental change of a coastal marsh, 1-centimeter (cm) foraminiferal subsamples were taken from seven sediment push cores collected in the Grand Bay National Estuarine Research Reserve (GNDNERR), Mississippi (MS), in October 2016. The push cores were collected along two, shore-perpendicular transects at 5, 15, 25, and 50 meters (m) from the
