|---|---|
| Short name | JR20131112 (JR291) |
| Objectives and Narrative |
Cruise to the South Georgia region nested inside a combined logistic and science leg during voyage 23 of the RRS James Clark Ross. As part of the logistics element the ship undertook base reliefs at Bird Island and King Edward Point (South Georgia), and Signy (South Orkney Islands). During the science part of the cruise we undertook the Western Core Box survey to determine the distribution and biomass of krill northwest of South Georgia, refurbished the biological moorings in the South Georgia region.
The main deliverable of the WCB is a consistent unique time series of mesoscale distribution and abundance of Antarctic krill and an understanding of the physical environment they are within at South Georgia, South Atlantic (1996 - current). These data are required to understand the long term variability in krill biomass at South Georgia and the influences from climate variability, fishing pressure and predation. Standard data sets include 1) Underway calibrated scientific biological echosounder acoustic transects 2) Vertical CTD profiles and continuous underway data 3) Stratified RMT8 hauls macrozooplankton/micronekton hauls 4) Targetted RMT8 hauls macrozooplankton/micronekton hauls Four moorings are recovered and redeployed for sustained observations of zooplankton density and carbon export. Two shallow moorings, one near Signy and one on the South Georgia shelf, and two deep moorings located north-west and south-west of South Georgia. Measurements were made at these moorings sites (as well as two other additional sites) for carbon export (thorium, polonium isotope work and snowcatcher observations with collaborators from NOC, Southampton) and for zooplankton behaviour and effects of ocean acidification. |
