Sea ice volume, its uncertainty and changes over the last decade. Green full line indicates our best estimate and its uncertainties of about 13%. For comparison previous results are shown: Black dashed line shows ICESat results from JPL/ Kwok et al. (2008) and grey dashed line CryoSat results from UCL/ Laxon et al. (2013). Green dashed line shows results for sea ice volume when the same values for snow depth and ice density are used as for CryoSat-2 data, indicating that the decline may have been less dramatic than reported previously.
In September 2013 the Nansen Environmental and Remote Sensing Center (NERSC) coordinated and lead a scientific cruise with the Norwegian coast guard ship KV Svalbard. Seven institutions from Norway, USA, Israel and France participated in the fourteen day long cruise.
UNDER-ICE is an interdisciplinary project involving physical oceanography, ocean acoustics, sea ice research and studies of biological production (net community primary production) in Fram Strait and northwards towards the Gakkel Ridge.
The project will focus on observational and modelling studies of water masses, fluxes and physical-biological processes in ice-covered areas and the marginal ice zone (MIZ). Innovative observing systems based on ocean acoustics, hovercraft and gliders will be applied to collect ocean and sea ice data in a series of field experiments from 2013 to 2016. The new data will be combined with existing data, including satellite data and state-of-the art numerical models to study processes of importance for the Arctic climate system.
