Arctic deep waters

Vetenskapsrådet grant 2018-03859, 2019-2022
= My current main research;
= PhD student Salar Karam (I am the main supervisor), 2019-2023.

The return of the Weddell Polynya

Rymdstyrelsen grant 164/18, 2019-2021
= My other main research;
= Postdoc (recruitment ongoing)
+ UGOT’s internal funds, 2018-2022
= PhD student Martin Mohrmann, co-supervised with S. Swart and H. Ploug.

  • Martin has been deploying autonomous profilers in 2019 and 2020;
  • Determined that the upcoming opening could have been detected 5 days ahead via infrared satellite remote sensing [13]; now the Rymdstyrelsen project will extend this early warning to several weeks/months;
  • Wrote more on how exceptional this event has been [14][17].

Greenland melting and North Atlantic circulation

VINNMER-Marie Curie Cofund, dnr 2015-01487, 2015-2018
= My postdoc at Göteborgs Universitet with Anna Wåhlin:

  • Collected hydrographic data and produced the first map the  path of meltwaters from Petermann Glacier out of its fjord into Nares Strait [8];
  • Modelled the oceanic circulation of Nares Strait and determined its sensitivity to initial conditions (Master’s student’s work) (15);
  • Quantified biases in full depth water properties and deep water formation processes in the North Atlantic in CMIP5 models [10];
  • Determination of ocean currents from infrared remote sensing – collaboration with Chalmers University of Technology to try and increase the North Atlantic data coverage [6][9][11].

Deep Southern Ocean in climate models

NERC Open CASE, award number 1093171, 2011-2015
= My PhD at UEA (UK) with Karen Heywood, David Stevens, and Jeff Ridley at the UK MetOffice:

  • Quantified biases in Antarctic Bottom Water temperature and salinity in CMIP5 models [1][2];
  • Determined the causes for these biases: impossibility to export shelf water due to the mixing scheme, and open ocean deep convection in the Weddell Polynya[1][PhD thesis];
  • Quantified the consequence of these biases on climate change projections [3];
  • Found a numerical solution to suppress the unrealistic formation process [4].
