2018-OctoberAustralian Coastal and Oceans Modelling and Observations (ACOMO) workshopConstable et al.The role of models in facilitating the first marine ecosystem assessment for the Southern Ocean (MEASO)A first Marine Ecosystem Assessment for the Southern Ocean (MEASO) is under development. It will facilitate contributions from the broader Antarctic and Southern Ocean marine science community to the 6th Assessment Review (AR6) of the Intergovernmental Panel on Climate Change (IPCC), the IPCC Special Report on the Ocean and Cryosphere in a Changing Climate (SROCC), and to the Commission for the Conservation of Antarctic Marine Living Resources, amongst other bodies. MEASO intends to provide a forward-looking assessment of what trends in Southern Ocean ecosystems are happening now and into the future, and what may need to be planned for, in terms of research and management. The aim is to have a quantitative assessment that enables managers to achieve consensus in adapting their management strategies to ecosystem change. MEASO began at an international conference held in Hobart in early April 2018 and is supported by IMBeR ICED and CLIOTOP, SOOS, SCAR, and the Australian Antarctic Program. The conference provided an opportunity to share relevant science, enhance community input into the design and planning of the MEASO, and to develop a work plan. Ecosystem modelling is central to achieving these assessments. This presentation will summarise the draft framework for MEASO-1, and the roles that models are playing to integrate disparate data sets into an ecosystem assessment. The first MEASO is expected to be published in the first quarter of 2019, for use in the IPCC AR6. Then work will commence toward subsequent MEASO iterations on a cycle that aligns with IPCC reporting.

Marine Ecosystem Assessment for the Southern Ocean (MEASO)

A first Marine Ecosystem Assessment for the Southern Ocean (MEASO) is under development. MEASO aims to provide a forward-looking assessment of what trends in Southern Ocean ecosystems are happening now and into the future, and what may need to be planned for, in terms of research and management. The aim is to have a quantitative assessment that enables managers to achieve consensus in adapting their management strategies to ecosystem change.  MEASO officially began at an international conference held in Hobart in early April 2018 (http://www.measo2018.aq/). The conference provided an opportunity to share relevant science, enhance community input into the design and planning of the MEASO, and to develop a work plan.  Since the conference, summaries of information available for a MEASO have been compiled in order to determine what can be used to assess status and trends within the Southern Ocean on regional and circumpolar scales. This review includes a record of field programmes and ecological surveys, current Southern Ocean syntheses, model coverage and assessments. The types of biological data collected from the field programmes are also being summarised, based on an open, international survey of researchers.  For this survey, an indication of where and when national research programmes have conducted field work were requested, particularly for measures of density (abundance) for different taxonomic and functional groups within the benthos, pelagos and plankton as well as birds and marine mammals. To date 12 countries have contributed to the data survey, coverage of which can be viewed on the Southern Ocean Knowledge and Information wiki: http://soki.aq/display/MEASO/MEASO+Data+Availability.  The work program for the first assessment is detailed in the paper.

2018-JuneSCAR Open Science ConferenceConstable, A.J. et al.Marine Ecosystem Assessment of the Southern Ocean: Outcomes of MEASO2018Status and trends of Southern Ocean ecosystems are being assessed to update the SCAR Antarctic Climate Change and Environment Report and to provide inputs to the Sixth Assessment Review of the IPCC. These assessments are also intended to provide scientific inputs on marine ecosystems important to the Committee on Environmental Protection under the Antarctic Treaty and to the Commission for the Conservation of Antarctic Marine Living Resources. Interpretable measures of change in habitats, species and food webs are being synthesised for four sectors of the Southern Ocean (East and West Pacific, Atlantic and Indian), and divided into assessments for coastal/sub-polar and subantarctic areas. Results from the recent Marine Ecosystem Assessment for the Southern Ocean (MEASO) conference in Hobart in April 2018 will be presented on behalf of many scientists from ICED, SCAR Life Sciences, AnT-ERA, AntEco and SOOS. We summarise the conclusions and gaps in the assessments for each sector and highlight directions for the next MEASO.
2018-JuneSCAR Open Science ConferenceTreblico, R. et al.Models and Methods to Support Marine Ecosystem Assessments for Polar OceansA fundamental challenge for marine ecosystem ecology and management is that the properties that determine how ecosystems function are extremely hard to observe and measure - a challenge that is made even more difficult by the remote and challenging environment of the Southern Ocean. Furthermore, because of the scale and complexity of Southern Ocean ecosystems, it is hard to know how to robustly measure and summarize their overall status, and track how status is changing (i.e. to measure trends). In response to these challenges, there is growing international coordination to develop complementary suites of observation and models to enable quantification of ecosystem status and trends at circumpolar scales. At the recent Marine Ecosystem Assessment for the Southern Ocean (MEASO) conference in Hobart in April 2018, we sought to identify and synthesise current capabilities and to identify key future priorities for models and methods to support ecosystem assessment in the Southern Ocean. In this presentation, we summarise the outcomes of these discussions. We also consider similarities and differences between Antarctic and Arctic ecosystems that may help develop synergies in approaches to undertaking polar marine ecosystem assessments generally.
2018-JuneSCAR Open Science ConferenceConstable, A.J. et al. Benchmarking Southern Ocean Ecosystems in 2022-2023: A Proposal from MEASO2018Circumpolar assessments of change in the Southern Ocean ecosystem have been advancing over the last two decades. The Census of Antarctic Marine Life during the International Polar Year (leading to the SCAR Biogeographic Atlas of the Southern Ocean) and Southern Ocean GLOBEC made substantial progress in unifying approaches to characterising these ecosystems. The Fifth Assessment Review by Working Group II of the IPCC highlighted that long term observations to measure ecosystem change are a priority. To date, long-term whole-of-system biological observations in the Southern Ocean have been mostly concentrated in the Antarctic Peninsula and Scotia Arc. The scientific communities of IMBER's ICED program, the Southern Ocean Observing System and SCAR Life Sciences have been designing a program of work to advance these earlier programs to have sustained circumpolar measurements of the Southern Ocean ecosystem for assessing change. A program of co-ordinated circumpolar measurements of the ecological state of the ecosystem in 2022-2023 is to be considered at the MEASO2018 conference in April 2018. The plans arising from these discussions will be summarised in this presentation on behalf of contributors so far, with invitations to participate in further co-ordination and implementation of the program along with synthesis of results.
