Installation of automatic weather station (AWS) on the ice sheet above Terra Nova Bay during January 1988. The AWS measures wind speed, wind direction, temperature and pressure and transmits this information to satellites passing overhead, which relay the data to the United States for analysis.

Bases and Camps:
McMurdo Station, Antarctica - the base of United States operations. Located in the Ross Sea, this is the largest research station in Antarctica. As many as 1,200 scientists and support personnel live in McMurdo during the summer field season.
Terra Nova Bay Station, Antarctica. This is the base of Italian Operations in Antarctica, located in the Ross Sea about 200 miles NW of McMurdo.
Living and working quarters at South Camp, West Antarctica.
Scott Base, Antarctica -Also on Ross Island near McMurdo, Scott Base serves as a central for New Zealand Antarctic operations.

Twin Otter airplane used for transportation during the Nov.- Dec. 1992 field program in West Antarctica.
Wheeled C-130 Aircraft used for intercontinental flights between New Zealand and Antarctica. Ski-equipped C-130's are also used for operations within Antarctica and some intercontinental flights.
C-141 Aircraft also used for intercontinental flights between New Zealand and Antarctica. C-141's are much larger and faster than C-130's, but are not ski-equipped and therefore land only on the hard runway surfaces at Pegagus or the Ice Runway.
Helecoptor used to fly equipment and personnel to camps near McMurdo, such as the Dry Valleys.
Twin Otter landing at the Terra Nova Bay runway. This sea-ice runway allows little margin for error, as it is surrounded by mountains on 3 sides. Prevailing crosswinds also make the landing difficult.
Adelie Penguins at Terra Nova Bay.

An image of a model forecast from the Antarctic Mesoscale Prediction System, a collaboration between the National Center for Atmospheric Research and the Polar Meteorology Group is shown on the right. On the left is a satellite imager closeup of the storm, which occurred in the Ross Sea in December 2001. As can be seen by comparing the two images, the model predicted this event with high skill. Surface winds associated with this storm at times were above 100 mph. Low visibility and drifts over 10 ft hampered aircraft operations for an entire week.

Huge drifts bury a van at McMurdo station after a December 2001 storm with winds in excess of 100 mph.
A moderate snow event in McMurdo, seen in the distance is Discovery Hut on Hut Point Peninsula during 2002/2003 field season.
A moderate wind event (gusts over 40kts) picks up loose snow and obscures the horizon and low levels in McMurdo Sound during 2002/2003 field season.
Inexpressible Island and the Nansen Ice Sheet, Terra Nova Bay. Hells Gate is the area of ice between the island and the peninsula in the foreground. Scott's Northern Party wintered on this Island in 1912, experiencing some of the most persistant and intense winds in the world.

Mt. Erebus on Ross Island, at 3,800 m (12,500 ft), is the southernmost active volcano on Earth.
Another picture of Mt. Erebus taken from Pegasus Runway. In front of Mt. Erebus McMurdo, Observation Hill, and Castle Rock are all visible.
Mt. Discovery as seen from across the McMurdo Sound. Because of its location, observations at Mt. Discovery are often indicative of weather to come into McMurdo.
