Upcoming Workshop: the Global Biogeochemical Argo Fleet: Knowledge to Action

The Global Biogeochemical Argo Fleet: Knowledge to Action ( workshop will be held virtually over a series of Tuesdays in May (4, 11, 18, 25) and June (1). The workshop will explore the applications of a global data-stream from the Biogeochemical-Argo array in fisheries, carbon budget verification, and environmental forecasting, and will consider needs and perspectives of policy makers, and discussions regarding future support for the array.

Launching of the Southern Ocean United Nations Decade website!

In the context of the UN Decade of Ocean Science for Sustainable Development, the initiative is dedicated to setting up a framework that builds on understanding how human interactions with the Southern Ocean can benefit society in ways that will also protect and conserve the unique characteristics of this region. The framework of a Southern Ocean Action plan will be developed by the Southern Ocean Task Force under the coordination of the Scientific Committee on Antarctic Research (SCAR), with the collaboration of the Southern Ocean Observing System (SOOS), the Scientific Committee on Oceanic Research (SCOR) the International Oceanographic Data and Information Exchange (IODE), among several others.

This framework will allow the Southern Ocean community to inform the UN Decade of Ocean Science on priorities and activities in parallel with the Ocean Decade.

Reports on national activities were delivered by chairs or representatives of IIOE-2 National Committees. Subsequent progress reports of WG 1 (Science and Research), WG2 (Data and Information Management) and WG3 (Operational Coordination) highlighted important achievements made on publications, data and information management as well as communication.

Vladimir Ryabinin then provided an update on the UN Decade of Ocean Science for Sustainable development and feedbacks on IIOE-2 endorsement request.

During Day 2 and 3 of the meeting, progress reports of the science themes were delivered by the chairs. This was followed by presentations from invited projects, the Early Career Scientists Network, and results of GEOTRACES in the Indian Ocean.

An open Science Symposium was held on Day 4, with six long (15 minute) talks and seven flash (5 minute) talks on a diversity of topics including features of the Southern Bay of Bengal, Indian Ocean fisheries and variability, biological oceanography in upwelling regions, ocean circulation, climate change and extreme events in the Indian Ocean, among others.

Launch of the Second World Ocean Assessment (WOA II)

The Second World Ocean Assessment (WOA II), the major output of the second cycle of the Regular Process for Global Reporting and Assessment of the States of the Marine Environment, including Socioeconomic Aspects, will be launched on 21 April 2021, in connection with Earth Day 2021 which will be observed on 22 April. It is the newest outcome of the only integrated assessment of the world’s ocean at the global level covering all three pillars of sustainable development. 

The first World Ocean Assessment (WOA I), which was released at the end of 2015, established a baseline for measuring the state of marine environment, including socioeconomic aspects. WOA II focuses on trends observed since the publication of WOA I and current gaps in knowledge and capacity.  

The launch event will be streaming on 21 April 2021 at 10 a.m., EDT at the following webpage:
