DOOS aims at supporting the Global Ocean Observing System (GOOS) in shaping current Biogeochemical Essential Ocean Variables (BGC-EOVs) to reflect specificities of deep ocean observing. This shall safeguard that deep ocean needs in terms of observing requirements and capacities are fully embraced by the Global Ocean Observing System. The DOOS Biogeochemisty Task Team invites experts in deep ocean biogeochemistry observation to join a community revision of biogeochemical variables and how and why to observe them. The review results will be transferred to the GOOS Biogeochemistry Expert panel for consideration in the next general update of BGC-EOV specifications, anticipated by the end of 2020. Learn more about the initiative and the people behind it below.

Connection to the Global Ocean Observing System (GOOS)

The initiative adheres to EOVs identified by the GOOS Biogeochemistry Expert Panel where possible. It is fully committed to the approach laid out in the Framework for Ocean Observing (FOO) that works from societal and scientific needs (‘requirements’) towards observations and products appropriate to address those needs. We also stick to the GOOS approach to select for EOVs that are most feasible and most relevant, i.e., have the highest impact towards the requirements.

Deep-Ocean Biogeochemical Observations

A series of DOOS workshops and publications identified a large match between BGC EOVs selected by GOOS and those considered most relevant by deep ocean observers. In excess of the current set of EOVs, three additional variables focusing on the deep seafloor have been identified for potential suggestion to the GOOS BGC Expert Panel as candidate EOVs: Seafloor labile Organic Matter, Seafloor Oxygen Uptake, and Seafloor fluid and gas effluxes (focus on methane).

For any questions on the BGC EOV community revision please contact the DOOS Biogeochemistry Task Team leader Felix Janssen.

Team of Guiding Experts

The questionnaires have been prepared by a group of deep-ocean observers. These ‘guiding experts’ will turn your feedback into suggestions for submission to the GOOS Expert Panel as input to their set of BGC-EOVs and specifications.

EOVs of Other Disciplines

Following a different approach, the DOOS Physics and Biology / Ecosystem Task task teams are also working to help developing EOVs that account for deep ocean specificities. To get involved please feel free to contact Bruce Howe (Physics EOV Task Team lead) and Henry Ruhl (Biology/Ecosystem Task Team leader).
