Seminar: Modelling Earth's ice sheets stability diagrams

Tidspunkt

01. desember 2025, 10:00-11:00

Sted

BCCR seminar room (4th floor of the West wing)

Dear all,

 

The next BCCR Monday Seminar will be given by Jorge Alvarez-Solas from the Institute of Geosciences in Spain. He will present his work on "Modelling Earth's ice sheets stability diagrams". The seminar will take place in the usual BCCR seminar room (4th floor of the West wing) at 11:00.

We hope to see you there!

 Best regards,

Julia and Robin

 
Abstract

Previous work has shown that both the Antarctic Ice Sheet (AIS) and the Greenland Ice Sheet (GrIS) display hysteresis behavior, which means that if ice is lost due to an increase of temperature, a comparatively larger decrease is needed to recover the original state. This implies that the ice-sheet volume is multistable with respect to temperature and that the ice loss could be largely irreversible. I will show quasi-equilibrium simulations of these ice sheets together with the Laurentide and Eurasian paleo-ice sheets ran with the 3D thermomechanical ice-sheet model Yelmo. Then by finding the adequate mathematical shape of the stability diagrams I will focus on how an emulator can be built for the transient modelling of these ice sheets throughout the Quaternary

 Speaker information

I did my PhD in the LSCE (Laboratoire des Sciences du Climat et de l'Environnement) in France, focusing on the millennial abrupt climate change of the last glacial period. I continued with several post-docs in the faculty of physics of the Complutense University of Madrid, where I became Assistant Professor in 2019. Then, in 2023, I moved to the Spanish Research Council at the Geoscience Institute, also in Madrid. My research interests include ice-sheet and climate modelling for Heinrich and Dansgaard-Oeschger events, but also the glacial cycles and the future of the climate-cryosphere interactions

Stormtracks group meeting

Hi everyone, We’ll have our last Stormtracks group meeting of the semester this Wednesday (10.12) from 13:00 to 14:00 in U105. This week Ozan will give a talk on Results from Impetus4Change and EuroCordex simulations of regional climate with WRF. We’ll also have our holiday social with sweets! The meeting will be hybrid and you can join remotely via Zoom: https://uib.zoom.us/j/62886269543?pwd=ajWbi97zr0hbniaoQdZkUtD2EUSSri.1 Meeting ID: 628 8626 9543 | Password: qSKTfKU3 The meeting schedule for this semester is in the following google doc and we’ll have new schedule for next semester soon. https://docs.google.com/document/d/1yjicxkFp_8Y17LVftgksb1SnqSUSUXogg0pOFZfbK0g/edit?usp=sharing See you all there! :) Cheers, ~Hari and Yangfan

BCCR Monday Seminar: "Vertical carbon export during an under-ice phytoplankton bloom in the Chukchi Sea".

The last BCCR Monday Seminar of the year will be given next Monday (December 15th) by Robert Pickart from the Woods Hole Oceanographic Institution. He will present his work on "Vertical carbon export during an under-ice phytoplankton bloom in the Chukchi Sea". Abstract In order to quantify pelagic-benthic coupling on high-latitude shelves it is imperative to identify the different physical mechanisms by which phytoplankton are exported to the sediments. In June-July 2023, a field program documented the evolution of an under-ice phytoplankton bloom on the northeast Chukchi shelf. Here we use in-situ data from the cruise, a simple numerical model, historical water column data, and ocean reanalysis fields to characterize the physical setting and describe the dynamically-driven vertical export of chlorophyll associated with the bloom.
