This bi-weekly seminar, organized jointly by the University of Oslo, the Meteorological Institute, CICERO and NILU, invites renowned international experts to contribute to an informal series of lectures, meant to create interaction with the Oslo atmospheric and climate science community on recent highlights and analysis in the field. All seminars will be held on Thursdays.

Title: Seasonal and decadal changes to Arctic Ocean stratification in climate models and observations
Speaker: Erica Rosenblum
Abstract:
Climate models, which have been analyzed extensively to assess and predict current and future climate change and to inform policy, struggle to accurately simulate the rapid decline in Arctic sea ice. One possible source of this bias could be related to the vertical distribution of salt in the ocean, which controls the exchange of heat between the surface and deeper ocean. We compare simulations from two climate models to ocean observations collected below sea ice in the Canada Basin. In 1975, observations were collected by scientists living in ice camps, and in 2006–2012, they were obtained by automated instruments attached to sea ice. The observations indicate as much as six times greater surface freshening than the models between 1975 and 2006–2012. We show that the salt bias can be partly attributed to the models’ tendency to mix fresh water from the surface deeper than in observations, resulting in a saltier ocean surface. The results may provide insight for climate model improvement that could have wide-reaching implications because the vertical distribution of salt in the ocean directly impacts the vertical transport of heat and nutrients.
The Speaker:
I am a physical oceanographer and climate scientist. My research is focused on ice-ocean interactions, upper-ocean dynamics, and sea ice evolution using a range of tools including state-of-the-art climate models, hydrographic and satellite observations, idealized models, and lab experiments. Much of my work is aimed at investigating how seasonal ice-ocean processes have changed over the past few decades in response to global warming, and how accurately these changes are simulated in climate models. I completed my PhD at Scripps Institution of Oceanography in California, I am currently a postdoc at the University of Manitoba and a soon-to-be Assistant Professor at the University of Toronto.

BCCR Monday seminar is a weekly forum for the presentation of research connected to the Bjerknes Centre for Climate Research. Some of the talks are given by international visitors but the majority are presented by internal researchers. If you are interested to receive the seminar information and the zoom link regularly, you can send an email to Laura Dietrich <Laura.Dietrich@uib.no> and subscribe to the mailing list.
