McMurdo Station provides logistical support for operations across the continent. The food, fuel, and humans at the South Pole arrive via LC-130 cargo planes and traverse tractors from McMurdo. Numerous small field camps are staged from McMurdo and reached via helicopter, LC-130, or ski-equipped
Twin Otters. The Italian and New Zealand Antarctic programs also depend on fuel and military transport from McMurdo. All this in addition to supporting a year-round population of 200, and as many as 1000 inhabitants in the peak summer.
This requires a lot of fuel and supplies. Although summertime cargo planes bring down scientific equipment and fresh vegetables, much of the resupply is accomplished during the annual visit of a fuel tanker and a container ship. Winter Quarters Bay is a well-protected deep water harbor that attracted Robert Falcon Scott to the site in 1901, and which played an important later role in establishing McMurdo Station on this site. With the heavy American Navy icebreakers undergoing major overhaul or permanently decommissioned, the National Science Foundation contracted with a Russian icebreaker to open a passage to Winter Quarters Bay.
