Why should past ocean salinities matter?

The latest IPCC reports identified the global ocean circulation as a critical component in the Earth’s climate system, also building on evidence from the geological past as analogs for future climate change. Ocean circulation is driven by two basic essentials: temperature and salinity. Among the two, salinity is largely understudied. This talk aims to generate a synergy across disciplines to explore the ocean circulation that impacts climates with a special focus on its salinity component.

Short Bio

I am a foraminiferal micropaleontologist using modern analytical methods on marine microfossils to study past ocean circulation and climate dynamics within a land-ocean-climate nexus. Previously, as a Max Planck and Marie Skłodowska-Curie Postdoctoral Fellow, I honed skills in advanced paleoclimate techniques and proxy development. Currently, my research focuses on seaways and straits where low or high salinity-driven water exchange alters ocean circulation, contributing to significant climate shifts.


What is an AIAS Seminar?

The AIAS Seminar Series is a session of seminars held by the AIAS fellows, AIAS Visiting or Tandem Fellows or by other speakers proposed by the fellows. In each seminar, a fellow will present and discuss her/his current research and work-in-progress to an interdisciplinary audience for 30 minutes, closing off with 30 minutes for questions, comments and discussion.

All seminars are in-person and held in English. To attend online, please contact Cecilie Horshauge at cecilie@aias.au.dk by 9:00am on the day of the semimar as the latest to request a link.
