Cruise Inventory Information

Long name RRS James Clark Ross (74JC) cruise JR20090310 (JR200, JR200A, JR208)
Short name JR20090310 (JR200, JR200A, JR208)
Objectives and Narrative JR200 was the third of 3 cruises to the Scotia Sea region of the Southern Ocean, providing an autumn perspective to the fieldwork campaign of the DISCOVERY 2010 programme. Previous cruises include JR161 (spring) and JR177 (summer). The three cruises were designed to follow a similar cruise track (to allow inter cruise comparisons) and to sample across the range of environments that typify the Southern Ocean: the ice edge, shelf-seas, open-ocean, HNLC conditions, iron-enriched conditions and frontal areas. Through 2 BAS core science projects and a number of collaborations, we aimed to characterise ecosystem processes, from the impact of micro- and macronutrient availability on primary productivity, through to primary (zooplankton) and secondary (nekton) consumer processes and up to higher predator studies on abundance, distribution and diet.

The FLEXICON (Flexibility and Constraints in Life Histories) project consisted largely of a depth-discrete sampling programme to consider the distribution of different life-cycle stages and body states of key zooplankton species. Acoustic data supplemented these studies as well as providing detailed information on krill and fish swarm structures.
The FOODWEBS (Scotia Sea Food-webs) project took a number of complimentary approaches to consider linkages between different trophic levels, including micro- and macronutrient availability, phytoplankton studies, gut content examinations, stable-isotope analyses, higher-predator tracking studies. In addition, sediment traps deployed near to South Georgia will also provide key insights into carbon flux to the deep ocean.

In addition to the core DISCOVERY 2010 work, supplementary projects were supported on the cruise. The Dipycnal and Isopycnal Mixing Experiment in the Scotia Sea (DIMES) programme, of the Physical Sciences Division, had a remit to obtain greater resolution in physical oceanographic parameters across the Scotia Sea. Integration of DIMES into the cruise track increased the frequency of full-depth CTDs between core-sampling stations. The Antarctic Funding Initiative, Collaborative Gearing Scheme (AFI-CGS) project "Diseases of krill in the southern ocean: effects on standing stock and implications of changing climates", took advantage of our regular catches of live krill. Preserved samples will be examined in the UK at CEFAS and a pathogen profile generated. The AFI-CGS project "Iron availability and effects on phytoplankton communities in contrasting production regimes of the Scotia Sea: a seasonal perspective" contributed directly to the aims of FOODWEBS. Measurements of iron concentration were made throughout the cruise, and bioassays carried out, to examine the controlling influence of this micro-nutrient on primary productivity. This cruise also hosted three independently funded collaborators (Jose Xavier, Yves Cherel and Anton van de Putte) to assist in the fishing work throughout the cruise and in particular at the Polar Front.
