Earth Surface Dynamics (ESD) online seminar "Impact of low oxygen on coastal sediment biogeochemistry: the Baltic Sea as an example" by Pr. Caroline Slomp (University of Utrecht, The Netherlands)


Date: Wednesday, 12th May 2021 at 12:00 pm

Venue: Online via Zoom. Details below. 

Host: Dr. Cécile L. Blanchet (GFZ)

Dear colleagues,

We are pleased to announce the next Earth Surface Dynamics (ESD) online seminar on "Impact of low oxygen on coastal sediment biogeochemistry: the Baltic Sea as an example" by Pr. Caroline Slomp (University of Utrecht, The Netherlands), on Tuesday, 12th of May 2021, at 12:00. Please see details given below and in the attached poster.

We are also looking for presenters and participants for a small workshop that will take place in the afternoon (between 14 and ca. 16:30), with Caroline Slomp, to showcase some of our research on oxygenation dynamics at various time-scales and in different environments. The format will be informal 5-min talks followed by discussions. The workshop will be confirmed if we gather a sufficient amount of interest.

Best regards on behalf of the ESD organizing committee, Cecile Blanchet



Coastal waters throughout the world are rapidly losing oxygen due to human-induced eutrophication and global warming. This deoxygenation is dramatically altering biogeochemical processes in coastal systems, with major consequences for marine life. The Baltic Sea forms a prominent example of such an anthropogenic coastal “dead zone”. In this talk, I will discuss how low bottom-water oxygen is impacting key biogeochemical cycles in the Baltic Sea, and how the low oxygen state is recorded in the sediments. I will also discuss how this knowledge can be used to reconstruct past anoxia in the Baltic Sea and the relevance of these findings to other coastal systems.

Caroline Slomp is a professor of Marine Biogeochemistry at Utrecht University, The Netherlands. Her research focusses on marine nutrient, carbon and trace metal cycling and the response to environmental perturbation. The research is broad in scope and includes seagoing fieldwork, experimental research in the laboratory and modelling. Low oxygen marine environments (e.g. Baltic Sea, Black Sea, Gulf of Mexico) are currently a key focus.

The Earth Surface Dynamics seminar series aims to bring together the broad range of researchers on Telegrafenberg looking at Earth surface processes, e.g., hydrology, earth surface geochemistry, geobiology, geochemical/carbon cycling, geomorphology, etc. roughly once a month. The goal for these talks is to be broad and accessible and deal with big, global topics, so that non-experts and specialists alike can find them enlightening. If you would like to take part in the organizing of this seminar or would like to suggest speakers, please get in touch.
