Long considered too inaccessible to be significantly influenced by human activities, the deep ocean is now recognized to be impacted by a growing number of activities, including dumping and pollution, fishing, and oil and gas extraction. Within only a few decades of their inception, deep-ocean fisheries have depleted fish stocks worldwide and severely impacted seamount and cold-water coral habitats. There is an urgent need to properly assess the state of deep-ocean ecosystems, and establish a deep-ocean observation network to acquire proper baseline and time series data to assess natural cycles and anthropogenic change.
This DOSI working group will seek to ensure that assessment and management of the deep ocean are based on comprehensive input from the scientific community, including natural and social scientists.
Current Working Group Activities :
- Identify new leadership for working group
- Identify major ocean assessments, their scope, how the deep ocean is included and current adequacy of representation (topics and experts) and active contributors. e.g. WOA1. Members now poised to input to 2nd UN World Ocean Assessment
- Continue to increase awareness among both deep-sea scientific community and organizations developing assessments of need for input because of the varied and critical role of deep-sea
- Workshop to organize deep-ocean inputs to assessments, conduct knowledge gap analysis (linkages with all WGs e.g deoxygenation, plumes, pollution) and develop recommendations to rectify gaps. Consideration of adequacy of deep-sea representation in processes (topics and expert representation)
Recent Working Group Activities:
1) Input to the 1st United Nations World Ocean Assessment ensuring that many deep-sea scientists led and contributed to a number of chapters.
2) Produced 1st listing of international ocean assessments
3)Ensured the deep-sea is represented in the latest North Pacific Marine Science Organisation (PICES) Ecosystem Status Report.
4) Ensure deep-sea is represented in the IPBES reviews.
