Q&A: What do Arctic ice and Atlantic hurricanes have in common?

New research examines the North Atlantic Oscillation and its influence on global weather

The journal Nature Geoscience published a paper by Tom Delworth and his colleagues examining how a natural atmospheric force--the North Atlantic Oscillation--may be changing ocean currents in the North Atlantic. Among other impacts, the stronger ocean currents increase the amount of heat flowing toward polar areas, which could speed up Arctic ice melt and affect how hurricanes form. We asked Delworth a few questions about his study:

Scientists deploy autonomous sailing vessels to study whales, fish and seals

Unmanned technologies open new frontier in ocean science

NOAA Research and NOAA Fisheries have teamed up with academic and private sector partners to test innovative technologies that, if successful, will enable researchers to gather information on ocean conditions and marine species in remote areas of the ocean that are costly to reach and difficult to study.

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.
