OVER THE SIDE AND UNDER THE ICE A big red flotation sphere the top part of a mooring 180 meters (590 feet) long?is deployed into Hudson Strait. Over a year, the experimental mooring collected the first detailed measurements of water flowing out of icy Hudson Strait and into the North Atlantic. Changes in the outflow can have impacts on the climate in the North Atlantic region. (Photo by Fiamma Straneo, Woods Hole Oceanographic Institution)

TESTING AN EXPERIMENTAL DEVICE WHOI oceanographer Fiamma Straneo deployed an experimental mooring in the ice-covered Hudson Strait in 2004 to measure the flow of water through this climatically significant gateway to the Atlantic Ocean. She had to wait a year to retrieve the mooring to see how it worked. (Photo courtesy of Fiamma Straneo, WHOI)

GATEWAYS TO THE ATLANTIC The Arctic region contains a large reservoir of relatively fresh water. The fresh water is funneled out of the eastern end of the Arctic region through several small straits. Changes upstream of the gateways may be affecting the freshwater discharge to the Atlantic, which can cause changes in ocean circulation and climate.

RESCUED Just before WHOI oceanographer Fiamma Straneo was ready to deploy her mooring, the ship's captain was notified that 40 Inuits were stranded on an island 200 miles away. Luckily for Straneo, the captain ascertained that the Inuits were in no immediate danger, so Straneo did not have to scrap her only chance for the year to deploy her mooring. The mooring deployment proceeded, and then the ship picked up the stranded Inuits. (Photo by Fiamma Straneo, WHOI)
