Bigg recently received a grant to track the drifting floe, which could disrupt international shipping lanes.
Icebergs sailing into the ocean from West Antarctica may stay close to the continent's coastline, causing little hazard, or launch out into the Southern Ocean toward the Drake Passage near South America's Cape Horn.
Bigg and his colleagues plan to try to predict the iceberg's path up to a year in advance, based on ocean currents and prevailing winds. The modeling will help the shipping industry improve ice warnings, he said.
Huge icebergs such as the spawn of Pine Island Glacier often shatter into several pieces, and Bigg's team will track and model the fragments if the chunk collapses.
Already, a few small pieces have broken off the west side of the iceberg as it moved in the past few days, Bigg said. [Video: Antarctica's Pine Island Glacier Is Rifting]
"Each of the last three years has seen a giant iceberg calve, from either Greenland or Antarctica," he added. "Being able to track and forecast the tracks of these huge blocks of ice will be a major benefit to the shipping industry, particularly as more ships begin to use polar waters, as Arctic sea ice melts. This ability is what we aim to develop."
