Abstract
Our original plan was a highly ambitious one. Thinner than expected ice allowed relatively rapid transit, which, when coupled with extremely efficient deck deployments, led to a fulfilment of nearly all our over-the-side operations, both from the GEOTRACES and Repeat Hydrography perspectives. Ironically those same ice conditions which facilitated smooth station progress hindered the ability to perform all the ice stations we had hoped for, although we did attain 60% of our most optimistic expectation in that regard. Deteriorating weather conditions near the expedition’s end cost us only a small fraction of our intended goals. In the end we occupied 66 combined GEOTRACES, Repeat Hydrography, and ice stations. Given the highly complex nature of this expedition, which included the harsh environment, uncertainties of weather and ice, diversity of scientific operations, and working within an unfamiliar military framework, this expedition was an enormous success which all participants can be proud of.
