By combining detailed chemical measurements in the deep ocean, in the oil slick, and in the air, NOAA scientists and academic colleagues have independently estimated how fast gases and oil were leaking during the 2010 Deepwater Horizon oil spill in the Gulf of Mexico.

Summertime hail could all but disappear from the eastern flank of Colorado's Rocky Mountains by 2070, according to a new modeling study by scientists from NOAA and several other institutions.

NOAA scientists plumbed the deep ocean, probed the heights of the stratosphere, and surveyed some of the fiercest storm systems on Earth in meeting 2011's scientific challenges. Their discoveries are paying off in longer storm warning lead times, better understanding of our climate, and new knowledge about environmental disasters.

The amount of air pollutants in the atmospheric plume generated by the Deepwater Horizon oil spill was similar to a large city according to a new NOAA-led study published today in a special issue of Proceedings of the National Academy of Sciences.

A recent mission marked the completion of a five-year collaboration between the United States and Canada to survey the Arctic Ocean. The bilateral project collected scientific data to delineate the continental shelf beyond 200 nautical miles from the coastline, also known as the extended continental shelf (ECS).

Great Lakes perch lovers will find good news in a new NOAA study that shows yellow perch efficiently eliminate a harmful algal toxin from their tissues. The findings suggest that unless the fish are caught during a toxic algae bloom, eating them will not likely expose people to unsafe levels of the toxin known as microcystin.

NOAA's commitment to science was further solidified today with the release of a scientific integrity policy by Jane Lubchenco, Ph.D., undersecretary of commerce for oceans and atmosphere and NOAA administrator.
