+1 302 645 4208

Departure: Mar 27, 2017

Puntarenas, Costa Rica

Arrival: Apr 19, 2017

Manzanillo, Mexico

Operations Area

Eastern Pacific Rise
Lat/Lon: 9° 50.105′ N / 104° 17.087′ W
Depth Range: 2400 / 2600
Will the vessel be operating within 200 NM of a foreign country? no
Are visas or special travel documents required? no

Science Objectives

1) document the extent of nanoparticulate pyrite, other metal sulfide nanoparticulate phases and other iron nanoparticulate phases emanating from hydrothermal vents and diffuse flow regimes.

2) document sulfide and iron oxidizing microbes in various parts of the ecosystem including on mats, basalts, etc.

3) dissolved manganese speciation in the water column

Science Activities

1. Sampling of hyrothermal vent fluids and plumes for chemistry and diffuse flow fluids for chemisry and for sulfide and iron oxidizing microbes
2. In situ voltammetry measurements using HOV Alvin
3. Samples will be analyzed aboard the Atlantis and processed for further analyses in the home laboratory.
4. Collection of different mat material and macrofauna; e.g., tubeworms, mussels, shrimp that may harbor sulfide and iron oxidizing microbes.
5. up to 4 CTD casts
