R/V /Oceanus, Voyage #466 (OC466)
11 July 2010 – 21 July 2010

 
The research objectives are to test several hypotheses related to the  production of methylmercury in the marine environment (especially  sediments) through field collections (air, water, sediments and biota),  shipboard experiments, and laboratory tests. 

 Planned scientific activities on this cruise will focus on 12-14 coring  stations that span a range of sediment texture and biogeochemistry on  the continental shelf and slope. Box-coring will be conducted at each  station. Trace-metal-clean rosette collections of water and open-closing 
 
Planned scientific activities on this cruise will focus on 12-14 coring  stations that span a range of sediment texture and biogeochemistry on  the continental shelf and slope. Box-coring will be conducted at each  station. Trace-metal-clean rosette collections of water and open-closing  net sampling for zooplankton are also planned for each coring station.  High-resolution water-column profiles will be made at seven or more of  the sampling locations. Underway mercury sampling of air and water will  be conducted throughout the cruise. Many mercury related on-board  experiments will be carried out and numerous samples will be preserved  for later laboratory analyses and experiments. 

 The operations area will be the North West Atlantic Ocean Continental  Margin south of Nova Scotia to about the latitude of Delaware Bay  Lat/Lon: 42$B!k(B 15.0$B!l(B N / 66$B!k(B 20.0$B!l(B at a depth  range: 100-150 / 3000 meters.
