Images: Current Events off Antarctica

The newly discovered Antarctic Peninsula Coastal (APCC) Current hugs the west coast of the 745-mile-long peninsula. The current is reinvigorated as summer begins by fresh meltwater from the peninsula?s mountains, which also washes nutrients from land into the ocean. APCC waters may inject nutrients and juvenile krill from Marguerite Bay into the much larger Antarctic Coastal Current (ACC)to foster marine ecosystem farther away. Red, black, and red/black dots represent sites where moorings were deployed in various years to help measure currents. Solid blue arrows respresent areas where the new APCC was observed directly; dotted blue arrows represent the current's possible, still-unobserved pathways.

MIT/WHOI Joint Program graduate student Carlos Moffat used an instrument called a CTD rosette to measure temperature, salinity, and other water characteristics on a 2005 research cruise aboard R/V Revelle that started in Tahiti (16?S).

By the time the six-week cruise ended in the Southern Ocean (71?S), Moffat had put away his shorts and was seeing icebergs. (Courtesy of Carlos Moffat, Woods Hole Oceanographic Institution)
