Abstract: A stamucha (grounded pressure ridge) was found in 'Van Mijenfjorden', Spitsbergen during February of 1997. The surface and keel geometry of the stamucha was surveyed between March and June, 1997. Temperature distribution was continuously monitored by thermistor strings, and drillings were made to estimate ridge porosity and composition. The stamucha measured 10x10m at the water line and the maximum thickness was 4.4 m, with an average thickness of about 3.0 m. The estimated porosity ranged from 10 to 25%. The paper presents the physical characteristics of the stamucha and relates the temperature data to consolidation and meteorological data from the area.
