"One of the pioneering aspects of this project is observing the changes in the ocean and observing the changes in the atmosphere at the same time," says Ian Renfrew, a meteorologist at the University of East Anglia in the U.K. who coordinated the work of the plane with that of the ship.view more

One of the most dramatic features of recent climate change is the decline of summer Arctic sea ice. The impacts of this summer ice loss on northern society, on Arctic ecosystems, and the climate both locally and further afield, are already being felt.view more
But without the storms, the rest of the world could face weather disruption. They are vital to the global thermohaline circulation in the ocean, which underpins ocean currents and weather systems, say Alan Condron at the University of Massachusetts, Amherst, and Ian Renfrew at the University of East Anglia in Norwich, UK.view more
Recent ice shelf retreat on the east coast of the Antarctic Peninsula has been principally attributed to atmospherically driven melt. However, previous studies on the largest of these ice shelves – Larsen C – have struggled to reconcile atmospheric forcing with observed melt.
The Nordic Seas have a significant impact on global climate due to their role in providing dense overflows to the North Atlantic Ocean. However, the dramatic loss of sea ice in recent decades is creating a new atmosphere-ice-ocean environment where large swathes of the ocean that were previously ice-covered are now exposed to the atmosphere.
Surface melting on Antarctic Peninsula ice shelves can influence ice shelf mass balance, and consequently sea level rise. We show that summertime cloud phase on the Larsen C ice shelf on the Antarctic Peninsula strongly influences the amount of radiation received at the surface and can determine whether or not melting occurs.
The gyres of the Iceland and Greenland Seas are regions of deep-water formation, driven by large ocean-to-atmosphere heat fluxes that have local maxima adjacent to the sea-ice edge. Recently these regions have experienced a dramatic loss of sea ice, including in winter, which begs the question have surface heat fluxes in the adjacent ocean gyres been affected?
The impact of a physically based parametrization of atmospheric drag over the marginal ice zone (MIZ) is evaluated through a series of regional and global atmospheric model simulations. The sea‐ice drag parametrization has recently been validated and tuned based on a large set of observations of surface momentum flux from the Barents Sea and Fram Strait.
