Summary of Field Work: |
Summary: The project will characterize physiological and molecular responses of copepods to variable feeding conditions and will assess the metabolic state of copepods within natural populations.
Copepods will be sampled from zooplankton net tows (part of routine LTER sampling). For shipboard feeding experiments water (up to 80 gallons, generally less) will be pumped from the subsurface chlorophyll maximum daily for 9-12 days. Copepods will be live-sorted using microscopes. A subset of copepods will be incubated at in situ temperatures within 2-gallon buckets (up to 56 buckets, which may be stacked). |
|
Summary of Facility Requirements: |
The activities described above require use of a ship. While either the Laurence M. Gould or the Nathaniel B. Palmer would be appropriate for the proposed studies, it would be efficient and highly desirable to consolidate these proposed activities with the scheduled LTER cruise in January (Nov-Feb) 2019.
On the ship, proposed activities require use of a cold room during the 9-day incubation experiments or some alternative solution to keep up to 56 2-gallon buckets (10 in. diameter) at a constant low temperature (they may be stacked). Space is required for one stereo microscope for isolating and photographing copepods. Activities on deck will include vertical or oblique tows to 300 m (necessary samples can likely be obtained from tows that are conducted as part of routine LTER sampling and associated process studies) and collection of seawater from the subsurface chlorophyll maximum using a pump. Specimens will need to be stored at -20° and -80°C.
We require access to shipboard meterological data and request access to CTD data collected in association with routine LTER sampling. |

Optimum Start Date:

Dates to Avoid: |
Need to collect C5 stage copepods of Calanoides acutus, Calanus propinquus and Rhincalanus gigas through surface tows.
I propose to participate in the LTER cruise, which is typically scheduled in January. |

Other Ship(s): |
Could use either the Gould or the Palmer, but would have great synergy with LTER cruise. Also possible to delay activity by one year if berth space is not available in January 2019.
Total days are minimum days to accomplish proposed research. If allocated a berth, I would take full advantage of all available science days on a longer cruise. (This would enable sampling a broader geographic region etc.) |

Description of Repeating cruise requirements: |
Not applicable. |
Justification/Explanation for ship choice, dates,
conflicts, number of days & multi-ship operations: |
I have requested a berth on the January 2019 LTER cruise, but in case this is not available and there is potential for participation on some other cruise, I have provided scheduling information.
Transit from Chile or nearest port, my understanding is that the trip typically requires 4 days in each direction. Mob and Demob is very limited...we have no heavy equipment. Science days largely driven by need for 9 days of shipboard incubation following sampling. If incubations begin early in the cruise, cruise could be shortened. |

Explanation/justification for requested
ports and dates of intermediate stops
or to list additional port stops |
I believe this is the traditional port from which the ship leaves. I have no real preference regarding start port. |

Explanation of Science Party Requirements and Technician Requirements |
Technician requirements would include assistance with zooplankton net tows (mostly as part of routine LTER sampling) and pumping of subsurface seawater. If possible, assistance or advice would be helpful in securing culture experiment within the cold room. |
