How Will First Responders Deal With Oil Trapped Under Ice?
As sea ice continues to melt in the Arctic and oil exploration expands in the region, the possibility of an oil spill occurring under the ice is higher than ever, says the Woods Hole Oceanographic Institution (WHOI). But how first responders will deal with oil trapped under ice in such an extreme and remote environment is a huge, unresolved question. “With the opening of the Northwest Passage a few years ago and more commercial ships routinely travelling through the area, there have been concerns among various government agencies that there’s no real infrastructure in place to respond to an oil spill below the ice,” said WHOI-engineer Amy Kukulya. “From a logistics standpoint, it’s very challenging to get resources to the Arctic.”
Critical Need for Autonomous Underwater Vehicles
Kukulya is leading multi-agency collaboration aimed at developing cutting-edge sensors and autonomous robot capabilities that will help improve oil spill responders’ situational awareness and decision-making during an emergency. “As oceanographers, we see a critical need for autonomous underwater vehicles (AUVs) that can survey spills under ice over long distances,” she said.
As part of the effort, she and her colleagues deployed a series of AUVs in late August off the coast of Santa Barbara, California (USA) to test the vehicles’ oil spill detection capabilities for rapid response during a real-world maritime oil spill. Collaborators on the project include the Department of Homeland Security (DHS), the US Coast Guard (USCG), the US Environmental Protection Agency (EPA), the National Oceanic and Atmospheric Administration (NOAA), the Bureau of Safety and Environmental Enforcement (BSEE), Monterey Bay Aquarium Research Institute (MBARI) and the Arctic Domain Awareness Center (ADAC).
Long-Range Autonomous Underwater Vehicle
The field programme featured two complementary AUVs, a REMUS-600 outfitted with custom oil sniffing and sampling capabilities, and a Long-Range Autonomous Underwater Vehicle (LRAUV), a new class of Arctic AUVs funded by DHS to provide a fast and persistent oil spill response for ice-covered oceans.

WHOI’s strength in marine operations and logistics, combined with the vehicle’s small form factor and easy-to-handle design, will enable quick mobilization in the event of an oil spill incident.
