The most recent data from
ice mass balance buoys in Storfjroden, Svalbard and on iceberg - fast ice in Fram Strait show that the melt season has started.
Nicolas Bergeot from the Royal Observatory of Belgium talks about the interesting research
on ice mass balance and Earth's geomagnetic field he and his colleagues are carrying out at the Princess Elisabeth Antarctica research station.

The most recent ice data, 10 June 2013, from a
SAMS ice mass balance buoy installed in the fast ice in Inglefieldbukta (N 77 ° 54», E 18 ° 17») reported an ice thickness of about 88 cm and snow depth 20 cm.
The responses of ice concentration, ocean temperature and salinity, and
associated ice mass balance before, during, and after cyclones at a variety of intensities will be documented.
The most recent calculations
of ice mass balance in the antarctic also do indicate loss of ice, though nothing close to the changes seen in the arctic sea ice and Greenland ice sheet.
Geophysicist Nicolas Bergeot talks about the research
on ice mass balance he and his colleagues at the observatory have been conducting in Antarctica, as well as the observations of solar activity they carry out at the observatory.
Shepherd, for example, is currently working on a review that will reconcile roughly 50 findings from the many techniques that have measured
the ice mass balance, and will hopefully settle on an accurate average.

# 46, in the interior of polar continents and very large islands (Antarctica, Greenland), increased precipitation as snow resulting from the increase in warmer air's capacity to hold moisture, results in an increase in
ice mass balance.
The model was then able to simulate surface temperatures to within 2 to 4ºC of observations and to provide a good simulation of
the ice mass balance (snow accumulation), with both aspects being better than at standard resolution.
This is corroborated by ice ablation data from
an ice mass balance buoy (Figure 2) that was deployed in April near Barrow and has moved through the Chukchi Sea.
Similarly, data transmitted from
an ice mass balance buoy located well outside of the ice edge in the western Chukchi Sea, suggest that while not of climatological importance, pans and cakes of ice may still be relevant as potential ice habitat or navigational hazard.
Secondary objectives: Four secondary objectives have been defined: - To assess the effect of a more accurate simulation of sea ice drift and deformation on the Arctic sea
ice mass balance and distribution properties of sea ice age.
Sea ice deformations also impact melting and freezing in leads, ridging and sea ice circulation, which are key players in determining sea
ice mass balance and age, and freshwater mass distribution in the Arctic Ocean.
Only a detailed analysis of buoy data and field observations will help resolve this question, but
an ice mass balance buoy placed on 1.4 meter thick first - year ice north of Barrow in April has managed to survive into the late melt season, drifting 1,000 kilometers to the North over the course of the summer.
According to Farjana Sikandar Birajdar, lead author of the study, the melting of glaciers would reduce
the ice mass balance even as it resulted in formation of new lakes with loose moraine.
