Power Washing (IMAGE) Woods Hole Oceanographic Institution Caption Mooring technician Andy Davies power-washes a seafloor tripod to remove growth that had accumulated over the past two years. The tripod holds instruments safely away from icebergs that are a common hazard southwest of Greenland, where OSNAP is monitoring physical, chemical, and biological conditions in the ocean as part of an international, multi-year effort to study a critical link in Earth's global ocean circulation and climate systems.
