AUGUSTA, Maine (AP) — A mapping expert with the Maine Department of Environmental Protection is using her expertise to help track and contain the massive oil spill in the Gulf of Mexico.

Ginger McMullin left Tuesday for Louisiana, where she will be working with the National Oceanic and Atmospheric Administration.

McMullin is an oil spill modeling expert and a geographic information system planner for the DEP. In her position, she is in charge of mapping sensitive marine areas for oil spill response planning purposes and for developing strategies on how best to use oil booms in case of a spill.

Officials say she will be in the Gulf region for about three weeks.
