Summary of Field Work: |
I will provide the first glider-based acoustic assessment of simultaneous distributions of phytoplankton, multiple zooplankton taxa, and silverfish in the Ross Sea, to elucidate trophic interactions and relationships with their environment. This study will focus in the Terra Nova Bay polynya and surrounding shelf waters in order to evaluate the progression of 1) phytoplankton, zooplankton, and silverfish distributions; 2) relationships of these distributions to sea ice and physical features; and 3) phytoplankton-zooplankton-silverfish interactions during the critical spring-summer transition.
I propose to: 1) Conduct acoustic surveys during one, 4-week deployment of a Slocum glider AUV with integrated multi-frequency Acoustic Zooplankton and Fish Profiler (AZFP) to map distribution and abundance of multiple zooplankton taxa and silverfish during spring-summer transition along Terra Nova Bay (TNB) polynya ice shelf and in continental shelf waters adjacent to TNB; 2) When possible while the ship is transiting during the collaborative research cruise, the USAP 38 and 120 kHz HTI acoustic system will be towed from the ship to complement glider-based acoustic measurements; and 3) Validate glider- and ship-based acoustic data of taxa composition and size during the glider deployment via ship-based sampling of zooplankton and silverfish using net tows and mid-water trawls (a minimum of ten times). |
|
Summary of Facility Requirements: |
This project requires: 1) a CTD/rosette (for cross-calibrations with the glider CTD at deployment and recovery); 2) a 1 m2 square frame Metro net (100 µm mesh); 3) a 10 m2 LED strobe-light-equipped MOCNESS (3000 µm mesh); 4) an Isaacs-Kidd Midwater Trawl (505 µm mesh; 1.8-10m2 frame); 5) 0.322 EM wire for towing; 6) 38 and 120 kHz HTI acoustic system or equivalent (Biosonics DT-X Echo Sounder) for towing (to complement glider acoustic data); 7) a zodiac for glider deployments/recoveries; and 8) laboratory space for tow/trawl sample processing. |

Optimum Start Date:

Dates to Avoid: |
A late spring start time (Nov-Dec, depending on ice and ship availability) is preferred. In order to capture associations between taxa and sea ice/circulation features and interactions between trophic levels, it is necessary to begin autonomous glider sampling during the onset of biological activity in the spring as the Terra Nova Bay (TNB) polynya extends/sea ice recedes and continue monitoring these relationships throughout the spring-summer season in TNB and the surrounding shelf waters. This is a crucial time period for the development of favorable conditions for phytoplankton productivity, crystal krill spawning and early development, and Antarctic silverfish. |

Explanation/justification for requested
ports and dates of intermediate stops
or to list additional port stops |
I request to deploy out of Punta Arenas, Chile. I am requesting collaborative ship use for this project, and during this time of year this is usually the port the Palmer departs from for field work in the Ross Sea and returns to prior to heading to McMurdo after a January cruise. I am flexible, however, with different start/end ports however, depending on the needs of the other science parties. |

Explanation of Science Party Requirements and Technician Requirements |
The Saba lab will require 2 personnel on board: 1 glider technician to lead glider deployment & recovery and adaptive glider sampling strategies during deployment, and 1 personnel to lead zooplankton/fish collection and sample processing. I am unsure if I need an "operator provided technician", but my team will need assistance with net tows/trawls and glider deployment/recoveries from a zodiac. |
