Video of the month

This month we publish a video provided by S. Brenner @ Brown University, USA.

In a new paper in Geophysical Research Letters, S. Brenner and members of the SASIP team investigate floe-scale effects on ice-ocean boundary layer turbulence. These numerical simulations of the marginal ice zone, produced with the “FloeDyn” sea ice discrete element model, show sea ice motion together with the underying ocean current field (white/blue colourmap and vector arrows shows), followed by the associated turbulence generation under the ice (cyan/red colourmap). Three different floe size distributions are investigated. Despite maintaing the same bulk sea ice concentration (50%) and ocean forcing for each of the cases shown, distinct turbulence patterns emerge for the three floe size distributions.
