The project is organized along three main activities:

Strengthen the existing infrastructure, community and tools

Work packages related to capacity building have transverse activities with the organisation of dedicated workshops and participations to conferences, the implementation of a Central Information System demonstrator and preparation of a roadmap designing the needs for the implementation of a global coupled acoustic-based observation-modelling system, inventorying what has already been done (existing cooperation patterns).

Improve the data, quality-control & standardize

Work packages related to data need to establish reference datasets for micronekton in several study areas (ecosystems) that will be used to check the data acquisition and quality approaches and formats used by different partners and how they fit with the data needs of models. Where there are data gaps for development and validation of micronekton models, innovative approaches will be identified to promote future collection of key missing data. This will take the form of a prototype information system for delivering micronekton density distribution of several functional groups in the Southern Ocean simulated over historical periods covering the satellite ocean color era (ie since the launching of SeaWiFS in Sep. 1997), with validation based on study areas of several systems in the Southern Ocean. Data will be distributed through the Central Information Service (this website, “data” section) by the end of 2017.

Design use cases

Work packages related to Uses cases will evaluate how existing model of micronekton biomass can use observation for a better design and validation. Additional acoustic observation models need to be developed to link predicted biomass of micronekton functional groups to acoustic signal from one to multiple frequencies.

End-users of the proposed acoustic-based observation-modelling system will demonstrate and quantify the role of micronekton in term of trophic link and Carbon flux between primary/secondary production of the Southern Ocean and the tremendous biomass of top predators.
