| dc.description.abstract | There is controversy as to the origin of the dome shaped hills (pingo-like-features (PLFs)) found on the Canadian Beaufort Sea continental shelf and slope. A detailed study of a PLF was undertaken to define its characteristics and to determine its origin.
Two cores were obtained, one each from the peak and moat which surrounds the feature and several acoustic survey lines were run over the PLF.
The cores were analyzed and compared for geotechnical properties, pore water cation, gas and organic carbon concentrations as well as foraminifera and palynomorph assemblages.
Core and Acoustic data strongly suggest a mud volcano type mechanism of formation of this PLF.
