R/V Oceanus, Voyage #442 (OC442) 5 November 2007 – 19 November 2007 Woods Hole, MA – Woods Hole, MA The main scientific research objective is to study the dynamics of the formation of the subtropical mode water of the North Atlantic. This water mass, with a temperature of close to 18°C, is formed just south and east of the Gulf Stream where there is energetic air-sea interaction and mixing as well as stirring. Different components of CLIMODE seek to quantify the magnitude of different processes at work in forming 18°C water. The planned activities include mooring recoveries, CTD casts and drifter deployments. The operations area will be the Northwest Atlantic Ocean east to 55°W, south to 36°N.
