To study the air-sea interactions that relate to climate variability, you need something -- like a buoy -- to hang out in the middle of the ocean to take consistent readings. In this photo, staff from Papahānaumokuākea Marine National Monument support the NOAA Ship Hi’ialakai on a buoy recovery and deployment at a site located some 60 nautical miles north of Oahu, part of a project called the Woods Hole Oceanographic Institution Hawaii Ocean Timeseries Site (WHOTS). With data from the project, researchers can help track climate changes, a subject of particular relevance to the health and future of the Monument.
