Editor’s note: This is the fifth dispatch from Jeremy Mathis, director of NOAA’s Arctic Research Program, who is leading a team of NOAA scientists on a research cruise in the Arctic aboard the USGCGS Healy.
Oceanic and Atmospheric Research (OAR) - or "NOAA Research" - provides the research foundation for understanding the complex systems that support our planet. Working in partnership with other organizational units of the NOAA, a bureau of the Department of Commerce, NOAA Research enables better forecasts, earlier warnings for natural disasters, and a greater understanding of the Earth. Our role is to provide unbiased science to better manage the environment, nationally, and globally.
