The Sea Ice Physics and Ecosystem experiment (SIPEX) was conducted in the East Antarctic pack ice zone between 115-130°E from 9 September - 11 October, 2007. In situ measurements of sea-ice and snow properties were conducted at 15 ice stations, together with ship-based ASPeCt observations. The ice and snow thickness varied considerably in different regions of the pack ice, with particularly thick ice associated with deformation and a strong slope jet in the southwest of the study region. The mean ice thickness was 0.99 m (1.57 m excluding the northern marginal ice zones), but varied from 0.61 m along the southern leg to 1.80 m along the western leg, with pockets of considerably thicker ice in some regions. Swell was observed on two occasions penetrating more than 330 km south of the ice edge into regions with 80-100% ice concentration. Ice thicknesses calculated from near coincident ICESat laser altimetry (1.74 m) are similar to the in-situ observations in the central pack (1.57 m).
