What is a MEASO?
A Marine Ecosystem Assessment for the Southern Ocean (MEASO) is a quantitative assessment of the status and trends of habitats, species and food webs in different regions. It aims to provide a common foundation for all end-users on which science can be developed, and policies and decisions can be made. It is intended to enable managers to achieve consensus in adapting their management strategies to ecosystem change, in order to continue to achieve their objectives for ecosystems.
A recent analysis by the Antarctic Climate and Ecosystems Cooperative Research Centre (illustrated to the right) explains the importance of a MEASO (Constable et al, 2017; http://acecrc.org.au/publication/southern-ocean-ecosystems/)
Four themes of a MEASO were considered over 4 days: (1) assessments, (2) responses of biota to change, (3) modelling and analytical methods, and (4) observations for underpinning assessments. A one-day policy forum considered the delivery of science into policy.
173 people attended from 23 countries. (75 women, 98 men). Early careers researchers (APECS) were well represented (57) and contributed greatly.
MEASO-I and its four pillars
A first MEASO is to proceed in 2018. It will build on existing reviews (e.g. Constable et al 2014; Gutt et al 2015), SCAR’s Antarctic Climate Change and Environment report (Turner et al 2009) and the SCAR Biogeographic Atlas of the Southern Ocean (de Broyer et al 2014). It will collate knowledge and assessments ready to hand, particularly to assist the Commission for the Conservation of Antarctic Marine Living Resources and to provide community input to the Intergovernmental Panel on Climate Change.
The process will then be reviewed to enable improvements in a second cycle over 5-7 years.
The four pillars to deliver a MEASO are: (i) methods for facilitating delivery of the information to non-scientific end-users, (ii) ecologies of key taxa in the ecosystem and their responses to changing habitats, (iii) field observations of status and, where possible, trends in biota, and (iv) methods for analysing distribution, status and trends as well as for modelling the past, present and future.

All Antarctic and Southern biological/ecological researchers are encouraged to be involved in MEASO. The MEASO report will be developed in a part of the Southern Ocean Knowledge and Information (SOKI) wiki (www.soki.aq). Parts of the MEASO pages are in the public domain:
