Monitoring Change in the Arctic Monitoring Change in the Arctic Expedition to the U.S. Arctic keeps in place some vital research While NOAA has had to cancel many of its planned research surveys in Alaska, it has been able to conduct a number of scaled-back research surveys in 2020. One such survey that will be finishing up this week is in the Arctic and was conducted on board NOAA Ship Oscar Dyson to collect critical data supporting a long time series involving many scientific partners.

Unprecedented 2018 Bering Sea ice loss repeated in 2019 Unprecedented 2018 Bering Sea ice loss repeated in 2019 During winter 2018 the sea ice in the Bering Sea reached record-low levels thanks to persistent warm southerly winds. These conditions caused the ice to retreat to the northern reaches of the 800,000 square mile body of water. Read more
Study: Reducing human-caused air pollution in North America & Europe brings surprise result: more hurricanes 11May2022 Read more A new NOAA study published today in the journal Science Advances about four decades of tropical cyclones reveals the surprising result that reducing particulate air pollution in Europe and North America has contributed to an increase in the number of tropical cyclones in the North Atlantic basin and a decrease in the number of these storms in the Southern Hemisphere. The study also found that the growth of particulate pollution in Asia has contributed to fewer tropical cyclones in the western North Pacific basin. Read more
