As part of OSMOSIS, multiple ocean glider deployments are planned in the vicinity of the Porcupine Abyssal Plain (PAP) Observatory. The overall objective is to acquire a continuous year-long data set utilising Seaglider technology. This data set will be of significant value to the consortium.

BODC are committed to the provision of robust data management support for all UK ocean glider activities. To achieve this we are working closely with glider teams in the UK, as well as with end users of glider data, such as the UK Met Office. 

Ongoing collaboration with the international community, through the Everyone's Gliding Observatories (EGO) initiative and associated projects, is enabling us to develop and maintain a glider data management model in synergy with the wider community.

Key elements of the proposed glider data management model include

  • Near real-time ingestion of glider data to BODC for secure archiving.
  • Near real-time quality control and reformatting to EGO specifications. Delivery to stakeholders, including the Global Telecommunication System (GTS) and the EGO-established Global Data Assembly Centre (GDAC) for glider observations, Coriolis.
  • Assimilation of a ‘definitive’ calibrated time series from each glider deployment into the National Oceanographic Database (NODB) and delivery to the GDAC.

Details of specific glider deployments conducted as part of OSMOSIS can be found under the OSMOSIS data inventory.
