Every month, OR&R’s Emergency Response Division provides scientific expertise and services to the U.S. Coast Guard on everything from running oil spill trajectories to model where the spill may spread, to identifying possible effects on wildlife and fisheries and estimates on how long the oil may stay in the environment. We also get requests to track and model other floating objects.

In February 2023, ERD responded to 13 new incidents in nine different states, one territory (Guam) and one of the United States Minor Outlying Islands (Johnston Atoll, located 750 nautical miles (1,390 km; 860 mi) southwest of the island of Hawaiʻi).
