Polar Poppers
These torpedo-shaped instruments, called polar profiling floats, drift nose-up at various depths through the Arctic Ocean while measuring water temperature and salinity. The floats are programmed to rise to the…
Read MoreDown We Go
A hole cut into the Arctic ice allows researchers to deploy an instrument into the ocean underneath for climate studies. If the hole closes and ice cuts the wire, the…
Read MoreOver the Side and Under the Ice
A big red flotation sphere is deployed into Hudson Strait to collect the first detailed measurements of water flowing out of icy Hudson Strait into the North Atlantic. Changes in…
Read MoreGateways to the Atlantic
A large reservoir of relatively fresh water in the Arctic region enters the North Atlantic through several small straits. Changes upstream of the gateways may be affecting the freshwater discharge…

The Autonomous Underwater Vehicle Sentry
WHOI’s free-swimming robot Sentry completed its 500th dive on October 16, 2018. The autonomous underwater vehicle has used its sonar systems to help scientists map the seafloor, track the Deepwater…
Read MoreThe Ocean Conveyor
A global system of currents, often called the Ocean Conveyor, carries warm surface waters from the tropics northward. At high latitudes, the waters cool, releasing heat to the atmosphere and…
