Snow depth and air temperature on sea ice derived from autonomous Snow Buoy measurements
2016
More observations of snow depth on sea ice are urgently
needed for various applications in polar and climate research.
Large-scale and seasonal snow depth products are
required for many in-situ, remote sensing, and numerical
modelling applications.
We developed a new buoy type to obtain time series of
snow depth and air temperature on Arctic and Antarctic
sea ice. The buoy is based on four sonic ranging sensors,
and transmits the data via Iridium satellites.
The buoy concept and design are based on low unit costs
and easy deployment. Snow buoys proved to be most valuable
when co-deployed with other buoy types.
Near real time data sharing into international networks for a
large user community: GTS, buoy programs.
