  Variability in sea ice conditions, combined with strong couplings to the
atmosphere and the ocean, lead to a broad range of complex sea ice dynamics.
More in-situ measurements are needed to better identify the phenomena and
mechanisms that govern sea ice growth, drift, and breakup. To this end, we have
gathered a dataset of in-situ observations of sea ice drift and waves in ice. A
total of 15 deployments were performed over a period of 5 years in both the
Arctic and Antarctic, involving 72 instruments. These provide both GPS drift
tracks, and measurements of waves in ice. The data can, in turn, be used for
tuning sea ice drift models, investigating waves damping by sea ice, and
helping calibrate other sea ice measurement techniques, such as satellite based
observations.
