Summary of Field Work: |
Characterization of genetic diversity along a transect running across the Drake Passage, crossing the Palmer LTER grid, the Amundsen Sea and the Roos Sea Gyre and ending on the Ross Sea Continental Shelf.
Along the transect we will be collecting surface and near-surface (<100m) waters using CTD casts at about 12-24 hr intervals. The timing of the cruise would ideally be timed with the austral spring bloom (January) |
|
Summary of Facility Requirements: |
We need a CTD rosette, equipped with fluorometer, light sensor and potentially backscatter, and sufficient lab space for filtering water and conducting microscopy and single cell isolation. |

Optimum Start Date:
|
1/5/2017 |
Dates to Avoid: |
Since our goal is to isolate and analyze diatoms from the water column we are keen to sample during the austral spring and summer, when they are most abundant. |

|
Are you or any member in your science party bringing in any science equipment items which are regulated for export by the International Traffic in Arms Regulations (ITAR) and/or the Export Administration Regulations (EAR)?
|
No |
If yes, have you applied for the necessary permits through your export control office?
|
No |

McMurdo Station, Ross Island, Antarctica |
Explanation/justification for requested
ports and dates of intermediate stops
or to list additional port stops |
These two ports are the start and end points of our request cruise track. For this project, we are particularly interested in the intervening waters b/t Punta Arenas and McMurdo. |

Explain Instrumentation or Capability
requirements that could affect choice
of ship in scheduling. |
Our instrumentation requirements are fairly simple for this project. We just need an outfitted CTD rosette.
