Description (see definition): A submarine trough trending NE-SW with depths reaching to 1,500 m below sea level. The trough extends SW from c. 7630S, 3500W, in the Weddell Sea; underlies Filchner Ice Shelf and the S part of Ronne Ice Shelf, S of Henry Ice Rise; and continues W to c. 8300S, 8500W, near Martin Hills. The portion NE of Henry Ice Rise was discovered in 1957-58 by a U.S. traverse party from Ellsworth Station and named "Crary Trough" after Albert P. Crary, Chief Scientist, U.S. Antarctic Research Program (USARP). The SW portion was traced by U.S. seismic traverse parties, 1958-64, and the whole delineated in greater detail by the SPRI-NSF-TUD airborne radio echo sounding program, 1967-79. The name "Crary Trough" was set aside by Advisory Committee on Antarctic Names (US-ACAN) at the suggestion of Dr. Crary, who recommended that the entire trough be named after Edward C. Thiel (1928-61), chief seismologist at Ellsworth Station, 1956-58, and leader of the traverse party that discovered this feature.
