Ice Gouge 1

Location: Amundsen Sea off Marie Byrd Land, Antarctica
Latitude: 74° 10' S
Longitude: 106° W

Image Width: 30km (17 miles)
Data: Shipboard multi-beam bathymetry

Description: The plowing action of moving ice masses cuts linear depressions, or ice gouges, into the seafloor sediments and bedrock near Antarctica. Inset shows geographic location.

Ice Gouge 2

Location: Okuma Bay, eastern Ross Sea, Antarctica
Latitude: 76° 37' S
Longitude: 153° 50' W

Image Width: 25 km (15 miles)
Data: Shipboard multi-beam bathymetry

Description: The plowing action of moving ice masses cuts linear depressions, or ice gouges, into the seafloor sediments and bedrock near Antarctica. Inset shows geographic location.

Ice Gouge 3

Location: Near Cape Adare on the western side of the Ross Sea, Antarctica
Latitude: 70° 55' S
Longitude: 168° 50' E

Image Width: 33 km (20 miles)
Data: Shipboard multi-beam bathymetry

Description: Shipboard multibeam bathymetry data show ocean floor gouges caused by icebergs breaking off the Antarctic continental ice mass. Areas without multi-beam data are darkened. Inset shows geographic location.

Keel Scar 1

Location: on the continental shelf, western side of the Ross Sea, Antarctica
Latitude: 73° 40' S
Longitude: 176° 15' E

Image Width: 33 km (20 miles)
Data: Shipboard multi-beam bathymetry

Description: Shipboard multibeam bathymetry data show ocean floor gouges caused by icebergs moving away from the Antarctic continental ice mass. Areas without multi-beam data are darkened. Inset shows geographic location.

Keel Scar 2

Location: on the continental shelf, western side of the Ross Sea, Antarctica
Latitude: 72° 08' S
Longitude: 173° E

Image Width: 33 km (20 miles)
Data: Shipboard multi-beam bathymetry

Description: Shipboard multibeam bathymetry data show ocean floor gouges caused by icebergs moving away from the Antarctic continental ice mass. At this location, these icebergs have probably broken off the Ross Ice Shelf. Areas without multi-beam data are darkened.
