Changing atmospheric acidity as a modulator of nutrient deposition and ocean biogeochemistry

A contribution from the SOLAS project and GESAMP Working Group 38, this paper by Alex Baker et al. in Science Advances, shows how anthropogenic emissions to the atmosphere have caused changes affecting the magnitude, distribution and deposition of nutrients supplied to the ocean, as well as the extent to which nutrient deposition interacts with the sea surface microlayer during its passage into bulk seawater, and the relative abundances of soluble nutrients in atmospheric deposition.

Farewell to Liz Gross

After 41 years of service to the oceanographic community, Liz Gross is retiring from SCOR.  Liz was the SCOR Executive Director from 1980 to 2000 when she passed the baton to Ed Urban, and since 2000, has been the SCOR Grant Officer.

A brief summary of some of Liz’s major contributions can be found at: https://conta.cc/2Uc2dhT

As Grant Officer, Liz is to acknowledge, among many things, for the timely reimbursements to the SCOR scientific community as they attended their working group, project, and capacity development activities and for keeping track of the SCOR grants and memberships. As she prepares to leave SCOR and retire in Canada close to her family, once again Liz passes the baton to Ed Urban, who will continue to support SCOR as a Financial Consultant.

Thank you Liz!
We wish you Fair Winds and Following Seas in your retirement. You will be missed!

SCOR projects and Working Groups endorsed by the UN Decade of Ocean Science for Sustainable Development

SCOR Working Group OASIS and research project GEOTRACES have been endorsed as programmes to support transformative Decade Actions. OASIS is aimed at developing an Observing Air-Sea Interactions Strategy. GEOTRACES is an international program designed to improve the understanding of marine biogeochemical cycles and distribution of trace elements and their isotopes. The SCOR Working Group DeepSeaDecade aimed at developing a global plan for survey/sampling deep-sea ecosystems to underpin deep-sea research, was also a key contributor to the endorsed programme Challenger 150 – A Decade to Study Deep-Sea Life and the International Ocean Carbon Coordination Project (IOCCP) will contribute to other five endorsed programmes related to ocean observations, oxygen and acidification.

How Climate Change And Security In The Indian Ocean Region May Impact On Australia

Nick D’Adamo, from the International Indian Ocean Expedition 2 (IIOE-2) Joint Project Office (JPO) and collaborators, make a case of the critical need to adequately monitor, understand and predict the relationships between the environmental, social, economic and geo-political elements of a changing Indian Ocean. This new understanding of the Indian Ocean will be fundamental to policymakers for the development of management strategies and also for the ecologies and human societies of island and Indian Ocean region communities.

Announcing the 7th edition of the Ramon Margalef Colloquia: “A cross-system view of the biological carbon cycle in the anthropocene”

The 7th edition of the Ramon Margalef Colloquia: “A cross-system view of the biological carbon cycle in the anthropocene” will be held online from the 5th to the 8th of October 2021. The Colloquium is addressed to recent PhDs and advanced graduate students and it will be an excellent opportunity to foster collective learning through discussions on the analogies and disparities concerning the ecology and biogeochemical functioning of aquatic and terrestrial ecosystems.

Now available at the Ocean Best Practices platform (https://repository.oceanbestpractices.org/handle/11329/1585), this document produced by SCOR Working Group 156, ‘Active Chlorophyll Fluorescence for Autonomous Measurements of Global Marine Primary Productivity’ is focused on single turnover methods, which are most commonly used in phytoplankton research, while recognizing that other approaches, including Pulse Amplitude Modulation (PAM) fluorescence techniques, are also employed with macro-algae, corals and terrestrial plants.

The group was established in 2019, bringing together researchers and instrument manufacturers from 10 countries and 5 continents, with the goal of developing standards of best practice for the application of single turnover active chlorophyll fluorescence (ST-ChlF) to examine phytoplankton productivity.
