IMOS Mooring Facility QA, QC & Product Summit June 5-9, 2017


This annual Australian National Mooring Network (ANMN) meeting is one of a series seeking to improve and where possible standardise QA and QC across the Moorings sub-facilities through common techniques, procedures and tools. It allows expert scientific, technical and operational staff – that is those actively involved in collecting and quality controlling the data – to get together to discuss the issues, swap methods and experiences to produce better data. 

The first two days a very much hands on training and inter-calibrating of techniques by the biogeochemical field samplers and laboratory processors. Wednesday and Thursday will focus on the time series data streams from the instrumented moorings. Experts have been invited to present on subjects relevant to the facility. Example troublesome data sets will be worked through – with a goal of producing a practical toolbox use protocol.  

An additional focus each afternoon will include a review of how best we can implement the production of growing long term time series products that will better service the research and wider user community. Approaches will vary for the very different data types: from monthly water samples and CTD profiles to scalar, vector and profiling moored sensor time series. There will be an assessment of what tools already exist and then a discussion to work out what developments are then needed to be worked on in collaboration with the AODN to produce a common tool.

We are excited to have speakers and attendees from the various operators across Australia, including CSIRO, the Australian Institute of Marine Science (AIMS), the University of Tasmania, the University of NSW, Sydney Institute of Marine Science, the University of Western Australia and of course the hosts South Australian Research and Development Institute (SARDI).

This meeting has broader application to facilities beyond ANMN and our Deep Water Moorings cousins to others. Attendance is welcome form across IMOS as we want to draw on wider expertise. This particular summit is perhaps more inward looking than in the past in response to the challenge of producing more readily useable time series products to further promote and ease uptake by users.

Inputs & Outputs

There is flexibility in the program to allow participants to provide examples of troublesome or interesting data sets so that the wider group can learn from or help address issues raised. So if you have something you’d like to present please let Craig Steinberg and Guillaume Galibert know. Please continue to use the toolbox and moorings GitHub as they provide a way to share information, raise issues and seek help from facility members.

Through the meeting we expect to refine our methods that will update our user guides and also develop QC protocols. Recommendations will be made as to how best to provide the research community with improved access to quality data including the development of long time series products now we have a decade of observations.

Discussion on the merits of forming a separate Biogeochemical Steering Committee to the Moorings Steering Committee and Task Teams to look at Toolbox and data product developments.
