Summary of Field Work: |
We will ask two highly integrated questions: 1) How do the widespread losses of kelp forests impact benthic primary production across the Aleutian Archipelago? 2) How do the widespread losses of kelp forests impact both onshore and offshore benthic biodiversity and community structure? Following this, we will estimate changes to NEP at ten islands where we have historic data on seaweed community composition and estimates of kelp canopy cover. To examine these questions, in situ and shipboard incubations will be conducted in both kelp forests and urchin barrens over a two-year period to look at both whole-community and individual-species rates of photosynthesis and respiration. This will involve SCUBA diving from small inflatable boats. Shipboard experiments for each species will be scaled by their biomass in the ecosystem and combined with in situ benthic chamber experiments of whole communities to estimate NEP. Benthic biodiversity and community structure within and offshore of each of these habitats will be assessed using diver surveys and shipboard benthic trawls. For this we will need a small benthic trawl. |
|
Summary of Facility Requirements: |
We will nee four small inflatable boats for diving, a CTD for water sampling, a small benthic trawl for biodiversity sampling, and laboratory space for processing samples and for conduction incubation experiments. |

|
Justification/Explanation for ship choice, dates,
conflicts, number of days & multi-ship operations: |
We have selected the Pt. Sur because it is the proper size and has all the needed equipment. We have used this ship before twice and found it to be ideal for the work we plan. The number of days is what is required to complete the work we plan. |

Explanation of Science Party Requirements and Technician Requirements |
We will have 2 PIs (Edwards and Konar), 8 divers and one non-diver scientist. The technician will be needed to operate the benthic trawl and CTD. |

Explain Instrumentation or Capability
requirements that could affect choice
of ship in scheduling. |
We need diving to do most of the work. The dredging will be used to sample diversity at 40 and 70 m depth using a small benthic trawl..
