Caption from Oceanus magazine, Vol. 53, No. 2, pg. 33:
Scientists deploy a RAFOS (Sound Fixing and Ranging) float during a research cruise. These instruments can passively follow ocean currents across different depths for up to two years.
Image Of the Day caption:
Scientists deploy a RAFOS float during a research cruise in the Denmark Strait to track the sources of sinking waters of the Atlantic Meridional Overturning Circulationa key component of the Great Ocean Conveyor that influences climate in the North Atlantic region. These instruments passively monitor deep ocean currents for up to two years. Their positions are tracked by underwater sound sources. The floats resurface at the end of their missions and transmit their data via satellite. WHOI physical oceanographer Amy Bower has used RAFOS floats to explore hidden deep-sea currents in the North Atlantic and the Gulf of Mexico.
Caption from Oceanus online:
Scientists deploy a RAFOS (Sound Fixing and Ranging) float during a research cruise in the Denmark Strait to track the sinking waters of the Atlantic Meridional Overturning Circulation (AMOC). These instruments can passively follow ocean currents across different depths for up to two years. Their positions are triangulated by underwater sound sources. After deployment, scientists are unable to communicate with a RAFOS float until the end of the mission, when it returns to the surface and transmits its data via satellite.
