The Ross Sea WG will assist delivery of coordinated and, where possible, standardised observations of essential physical, chemical and biological variables in the West Antarctic Peninsula in the Southern Ocean in support of SOOS objectives.
The Ross Sea is one of the most active sectors for Southern Ocean and Antarctic research, and forms a natural region for a working group. A previous SOOS Ross Sea Task Team developed a summary of observational efforts in the region, and this has served as a basis for the development of the regional working group. The recent announcement of the Ross Sea Marine Protected Area (MPA) is providing impetus to develop this working group, as the research needs of the MPA have strong synergies with those SOOS. This group is co-chaired by SOOS SSC member Dr Mike Williams (National Institute of Water and Atmospheric Research, NZ) and Dr Walker Smith (Virginia Institute for Maine Science, USA), and is open to all researchers from nations with active research programs in the Ross Sea.
The Ross Sea Working Group met for the first time 11-13 September 2017 in Shanghai, China, to develop an observation system for the Ross Sea region. The WG identified three key questions that motivate the need for an observing system in the Ross Sea. These are:
It was recognized there were different levels of existing knowledge underpinning each question. To balance these needs discipline based hypotheses were developed to motivate funding applications for the different observing system components. These are still being finalized, but broadly reflect the needs of the physical, biogeochemistry, and carbon compoents of the observing system, and many of the tropic levels in the benthic and pelagic ecosystems.
Complete design of the observing system will need a robust Observing System Simulation Exercise (OSSE) to assess where physical and biogeochemical observations are most effective. This will need to be coupled with analysis that incorporates understanding of life history, foraging and other geographic constraints on biological systems. However, several areas were identified as focus areas for observations because of either their dominant role, or the basic need for observations in poorly observed areas. These focus areas are:
Existing observation programmes such as the Italian Marine Observatory in the Ross Sea (MORSea) were recognized as being important due to the historical perspective they are able to provide, and their potential to serve as an ongoing backbone. However, in the case of MORSea, the need for international support while Italy is without a research vessel was identified as a significant risk for the observing system.
The SOOS objective of open data provision was endorsed by the meeting and participants encouraged to continue initiatives to achieve this across all disciplines.
The successful workshop was sponsored by the Institute of Oceanography, Shanghai Jiao Tong University, Shanghai, China; Ocean Carbon and Biogeochemistry Office, Woods Hole, MA, USA; Southern Ocean Observing System Office, Hobart, AUS; Second Institute of Oceanography, Hangzhou, China; and the National Laboratory for Marine Science and Technology, Qingdao, China.
