ship groundings

So far this year, OR&R has provided support for 141 incidents. During October 2023, OR&R provided response support for 23 incidents, including 16 new incidents in six different states and two in the U.S. Virgin Islands.

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 possible effects on wildlife and fisheries and estimates on how long the oil may stay in the environment. This month OR&R responded to 13 incidents in March, including oil discharges, grounded vessels, and other pollution-related incidents. 

As the Earth’s atmosphere and ocean continue to warm under the global threat of climate change, the future of coral reefs looks bleaker than ever before. With rising temperatures comes an increase in mass coral bleaching events, infectious disease outbreaks, and the process known as ocean acidification. Climate change not only affects the overall health of corals, it also impacts their resiliency. Changes to the frequency and intensity of tropical storms — another side effect of climate change — lead to storm seasons that do a massive amount of damage to coral reefs.

Every month our 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 possible effects on wildlife and fisheries, and estimates on how long the oil may stay in the environment.

This month OR&R responded to eight incidents, including oil discharges, sunken vessels, and hazardous material releases.

The waters surrounding the Puerto Rico archipelago are known for the diversity and beauty of the coral reefs. Those reefs are also under great pressure from population density, land uses, and shipping traffic.

U.S. coral reefs are impacted by 3 ­- 4 large groundings a year.  On Dec. 15, 2009 the danger became reality near Guayanilla Bay, Puerto Rico when the liquid natural gas carrier Matthew grounded on the coral reef there causing substantial harm. It wasn’t just the grounding that injured the coral. During attempts to free the tanker the bow of the ship was moved from side to side causing further injury to the reef structure.

The winter of 1976-77 was a bad time for oil spills in the United States. I was still in middle school, but I remember doing a science report on oil spills. In a short time period there were multiple major oil spills, including these:

World Hydrography Day is celebrated each year on June 21. But before we start thanking hydrographers, we first should explain: What is a hydrographer?

Basically, a hydrographer measures and documents the shape and features of the ocean floor and coasts. These scientists then create charts showing the ocean’s varying depths and the location of underwater obstructions, such as rocky outcroppings or shipwrecks. As our fellow NOAA colleagues at the Office of Coast Survey (an office full of hydrographers) further elaborate, “hydrographic surveying ‘looks’ into the ocean to see what the sea floor looks like,” with most of the work “primarily concerned with water depth.”
