Summary of Field Work: |
Long-term feeding experiments to assess the affect of diet on juvenile Antarctic krill physiology and condition.
We will primarily be transiting to Palmer Station where we will carry out this research project. The present ship time request is for 2 days on the south bound voyage to Palmer Station to collect Antarctic krill. We would like to target our efforts in the Bransfield Strait and then also in the Gerlache Strait if we do not collect enough krill in the Bransfield. Net tows should be done at night as from prior experience, we collect far more krill during night time tows. Since krill are patchy, it would be advantageous to use the ship's Biosonics DT-X echo sounder in order to first find aggregations of krill and then target them with the net.
Nets will be supplied by our research team - we will either use an IKMT (Isaacs Kidd Midwater Trawl) or a Tucker Trawl.
Once we have collected krill, we will place them in holding tanks that will need to be filled from the seawater supply. The tanks will either be placed in the aquarium room or on deck so that ambient temperatures can be maintained.
Once at Palmer Station, we will need to have the holding tanks hoisted over by crane to the Palmer Station pier, where they will be transported to the aquarium facilities on station. |
|
Summary of Facility Requirements: |
We will need the Biosonics DT-X echo sounder, or an equivalent echo sounder if this has been replaced.
We will need space in the aquarium room on board the LMG.
We will need access to the seawater supply system (unfiltered seawater). |

Dates to Avoid: |
I need to be at Palmer Station by the beginning of April. My proposed research will focus on autumn and winter Antarctic krill physiology and condition and therefore it is essential that I am there at that time of year. |

Justification/Explanation for ship choice, dates,
conflicts, number of days & multi-ship operations: |
My research will be conducted at Palmer Station from autumn to winter. I have requested 2 days of ship time on the LM Gould since I know that this is the vessel that is used for Palmer Station re-supply and turnover. The 2 days requested are for collecting Antarctic krill in the Bransfield Strait and Gerlache Strait. If I can collect enough krill in the Bransfield Strait, then I won't need to collect in the Gerlache. |

Explanation/justification for requested
ports and dates of intermediate stops
or to list additional port stops |
I know that the LM Gould always departs and returns to Rada Punta Arenas for voyages to Palmer Station. Therefore, this is what I have requested. |

Explanation of Science Party Requirements and Technician Requirements |
I will have two graduate students traveling with me to Palmer Station, they will assist me with the net tows and sorting the krill. I am requesting 1 marine technician to assist in the net deployments and, if necessary, the deployment and operation of the Biosonics echo sounder. |

Explain Instrumentation or Capability
requirements that could affect choice
of ship in scheduling. |
We will need to use the Biosonics DT-X echo sounder that the LM Gould has so that we can target aggregations of krill for our net tows. We will bring our own plankton nets.
