The CORE Group
WHAT IS THE CORE GROUP?
A group of leaders in the field of ocean autonomy, coming from a diverse range of technical and academic backgrounds; including ocean sciences, data management, engineering or software. The group will be at the core of the community, representing people and institutions from across Europe.
The core group activity and leadership will be clearly distinct from other initiatives like the OceanGliders steering committee of the EuroGOOS glider task team and other international groups. There will be instances that some members could be part of those groups, this is normal, and to a point unavoidable, but the core group must keep a distinct activity from them while keeping engaged and coordinated.
ROLE OF THE CORE GROUP
They will be in charge of leading the network and provide the direction of travel. They will:
- Contribute to defining and periodically reviewing the strategic vision, priorities, and long-term objectives of the European Glider Community (EGC).
- Provide expert advice on scientific priorities, technological developments, and methodological standards related to glider observations.
- Act as a liaison between national glider programmes, research infrastructures, and international initiatives.
- Foster collaboration, knowledge exchange, and synergies across the EGC.
- Attend quarterly EGC meetings.
CORE GROUP RESPONSIBILITIES
- Define yearly priorities, in the form of engaging activities like technical sessions, workshops, community and networking events.
- Promote the network activity, helping new members to find the information they need and presenting the network activity in national and international forums.
- Organizing a webinar series to advance EGC knowledge exchange.
- Provide strategic input to proposals and initiatives involving the EGC.
- Find the next cohort of members for the core group.
