A large-scale field experiment took place in the marginal ice zone in the Barents Sea in May 2009. Fresh oil (7000L) was released uncontained between the ice floes to study oil weathering and spreading in ice and surface water. A detailed monitoring of oil-in-water and ice interactions was performed throughout the six-day experiment. In addition, meteorological and oceanographic data were recorded for monitoring of the wind speed and direction, air temperature, currents and ice floe movements. The monitoring showed low concentrations of dissolved hydrocarbons and the predicted acute toxicity indicated that the acute toxicity was low. The ice field drifted nearly 80km during the experimental period, and although the oil drifted with the ice, it remained contained between the ice floes.
