Hats Off

October 29, 2017

These air-filled glass spheres encased in a protective polyethylene “hard hat,” are used to keep mooring lines upright, taut, and off the seafloor. This string of floats, was deployed recently as part of the Ocean Observaties Intiative (OOI) Irminger Sea Global Array to measure the physical, chemical, and biological conditions in the water and atmosphere at a critical location in Earth’s ocean-climate system.
