Departure: Jul 11, 2010 | |

Arrival: Jul 21, 2010 | |
| Woods Hole | |
Operations Area | |
| NW Atlantic Ocean Continental Margin South of Nova Scotia to about the latitude of Delaware Bay | |
| Lat/Lon: 42° 15.0′ N / 66° 20.0′ W | |
| Depth Range: 100-150 / 3000 | |
| Will the vessel be operating within 200 NM of a foreign country? | No |
| Are visas or special travel documents required? | no |
Science Objectives | |
| The objectives of this cruise 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. | |
Science Activities | |
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.

We will be using Amsteel cable (3/8 inch .. ?? need to check at WHOI storage). Lenth available is about 4000m. We will use Kevlar .. also about 3/8 inch ..as a backup. About 3000 m available. Require a separate drum and winch for the trace-metal sampling with rosette. Clean zooplankton collections will also be made using the Amsteel .. exchange nets and rosette and we will work off of the same winch. Trace metal clean block needed | |||||||||||
