Current Cast

The following people say they are currently involved with the Marine Sediments Lab in research, graduate studies, undergraduate studies or something that gets them a check!

Manuel Bringué

Manuel is a postdoctoral fellow with a foot in the MSRL and the other at the U. of Victoria (BC, Canada) where he obtained his PhD in 2015. Trained as a micropaleontologist, Manuel currently focusses on dinoflagellates and their cysts in the Cariaco Basin, using one of the longest sediment trap time series in the world! The general idea is to better understand the ecology of dinoflagellates in the coastal ocean, in terms of environmental preferences and interactions with other major planktonic groups. In turn, this will allow for more detailed dinoflagellate cyst-based paleoenvironmental reconstructions from sedimentary records. 

Kate Davis

Kate joined the MSRL as a postdoc after receiving her PhD from the University of California, Davis. She is broadly interested in the use of biogenic carbonates to reconstruct high-frequency events and abrupt climate change in the ocean. For her project in the MSRL, Kate will be looking at how the geochemistry of individual foraminifera records seasonal oceanography in the Cariaco Basin.

Kelly Gibson

Kelly is joining the MSRL as a postdoc, fresh from getting her PhD from RSMAS in scuyoga, the art of underwater meditation. Just kidding. For her dissertation research, Kelly used foram and sediment geochemistry to generate high-resolution paleoclimate reconstructions from the Cariaco Basin, VZ. Her first project with the MRSL will explore nitrogen isotope dynamics during Marine Isotope Stage 3, using Cariaco sediment cores.

Jorge Ontiveros

Jorge joined the MSRL as a postdoctoral fellow in the spring of 2016. Currently, his research centers in the used of redox-sensitive trace elements (e.g. Mo, U) and nitrogen isotopes to reconstruct shifts in the position and intensity of the oxygen minimum zone (OMZ) in the Eastern Tropical North Pacific (ETNP) from the last glacial period to the Holocene by using sedimentary records.

Eric Tappa

Eric has been attempting to keep things in order for the past 34 (yes, really) years.

Natalie Umling

Natalie received her B.S. in Geology and Oceanography at the University of North Carolina at Wilmington and is currently a PhD student in Geological Sciences. Her current research focuses on the release of carbon stored in intermediate waters as a source of CO2 during deglacial episodes of rapid atmospheric CO2 rise. She is developing a record of benthic and planktonic foraminiferal radiocarbon along with benthic B/Ca to examine changes in ocean ventilation and the biological pump as methods for glacial carbon storage. She is conducting this research using core material from Eastern Equatorial Pacific cores collected from the Panama Basin.
