November 19, 2006 The Antarctic Sun • 3 Sea ice strong-arms USAP into backup plan Fleet operations grooms new route to Marble Point for fuel, supply deliveries By Steven Profaizer Sun staff The iron grip of the sea ice has pre- vented the annual fuel tanker from reach- ing Marble Point Refueling Station since January 2004. No one yet knows if the sea ice will clear out this summer. But Marble Point is a crucial fuel stop for access to the McMurdo Dry Valleys, and fleet opera- tions isn’t taking any chances on it running dry. The department groomed a new snow route this season to facilitate the transport of regular supplies and about 350,000 liters of fuel to Marble Point’s thirsty tanks. Fleet operations will divide the fuel into four different trips down the nine-hour route to Marble Point. It will also make Photos by Gregory Murphy / Special to The Antarctic Sun two regularly scheduled supply trips along Above, heavy equipment operator Richard the new path.
