JGP95E classifies the global terrain into six different types (1: dry land below mean sea level (MSL), 2: lakes, 3: oceanic ice shelves, 4: oceans, 5: glacier ice, 6: dry land above MSL).
The polar bear travels long distances over vast desolate expanses, generally on drifting oceanic ice floes, searching for seals, its primary prey.

The model is initialised with atmospheric, oceanic, and sea-ice observational data and current anthropogenic and natural forcings, so that the simulations are representative of current real world climate.
This oceanic warming is melting ice on land and at sea, most notably with the dramatic summer declines in Arctic sea ice.
They start with fundamental principles we can all agree on and express these relationships in terms of atmospheric, land, ice and oceanic quantities.
Previous research has shown that in Antarctic coastal "polynyas" — open water areas ringed with sea ice — more oceanic life blooms in areas where melting glaciers are pouring more fresh water, and iron, into the sea.
Developping new observational tools and integrating new understanding into predictive models, Pierre continues his work to shed light on the processes controlling the oceanic melting of glacial ice and its implications for the climate system.
His research includes Cenozoic and Mesozoic geomagnetic polarity time scales; paleoclimatology, paleogeography and tectonics of the Pangea supercontinent; paleofield intensity variations; and magnetic properties of sediments, oceanic basalts and polar ice.
Current interests include Cenozoic and Mesozoic geomagnetic polarity time scales; carbon cycle and paleoclimatology, paleogeography and tectonics of the Pangea supercontinent; paleofield intensity variations; and magnetic properties of sediments, oceanic basalts, and polar ice.
