Ocean circulation and carbon cycle dynamics in the Pacific Southern Ocean during Late Pleistocene interglacials
The Southern Ocean is a key component of the global ocean overturning circulation, enabling water mass exchange between ocean basins, driving Antarctic Bottom Water and Antarctic Intermediate Water formation and providing the major return path of Circumpolar Deep Water (CDW) to the ocean surface. …

On the meridional heat transport and its partition between the atmosphere and oceans
… and its partition between the atmosphere and oceans using models and data. I focus on three primary questions: (1) What is the total heat transport and its partition between the two fluids? (2) What sets the magnitude of the total heat transport and to what extent is it sensitive to the …

Where the Ice Ends: Calving and Ice-Ocean Interactions at Helheim Glacier and Beyond
Continued mass loss of the Greenland Ice Sheet has contributed to sea level rise at a rate of 0.8 mm year$^{-1}$ since 2002, with ice dynamics accounting for $66 \pm 8$\% of the mass loss signal. One of the main components of this dynamic mass loss signal is iceberg calving, the detachment of ice …

Modeling Circulation Dynamics and Submarine Melt in Greenland Fjords
Meltwater accumulated on the Greenland Ice Sheet drains to glacier beds, discharging into fjords hundreds of meters below sea level. The injection of meltwater at depth generates an upwelling plume that entrains warm ocean water as it rises along the terminus, increasing submarine melt and driving …

Observation and inversion of seismo-acoustic waves in a complex Artic ice environment
… frequency seismo-acoustic waves in the Arctic Ocean ice canopy is examined through the analysis of hydrophone and geophone data sets collected in 1987 at an ice camp designated PRUDEX in the Beaufort Sea. Study of the geophone time series generated by under-ice explosive detonations reveals not …

Patterns and drivers of seasonal land-ice-flow around Antarctica
… the multi-annual acceleration of the Antarctic Ice Sheet, and the associated increase in its contribution to global sea level. Unlike the Greenland Ice Sheet, where ice velocity signals are well resolved over both inter- and intra-annual timescales, observations of seasonal signals are limited …

Coastal climate change and variability in the Benguela current system
… and Northern Benguela coast. To do so, the Ocean General Circulation Model NEMO (OGCM NEMO) is used. The model produces an unrealistic cooling trend in the Northern Benguela due to a positive trend in upwelling-favourable wind model forcing. The modelled warming trend in Southern Angola is …
