Highlights
Following a series of publications reporting on successful long-term deployments of profiling floats with various biogeochemical sensors (e.g. Boss et al 2008; Johnson, Riser, and Karl 2010; Körtzinger et al 2004) and years of international coordination, the BGC-Argo program was officially launched in October 2016, as an extension of the Argo Program (Biogeochemical-Argo Planning Group 2016; Johnson and Claustre 2016)
The global network is progressively maturing through a cluster of national projects, e.g. the French SOCLIM project, United States’ SOCCOM project, South Africa’s SOCCO BIO-ARGO project, and Chinese ReMOCA project in the Southern Ocean; the European REMOCEAN project and Japanese INBOX project in the subtropical gyres; the United States’ NAAMES project and UK-BIO-ARGO project in the subpolar gyres; as well as the French NAOS project in the Mediterranean Sea and Polar Area
Discussion took place on how to improve real-time quality-control procedures for chlorophyll fluorometry and delayed mode quality-control procedures of dissolved oxygen. This was important in light of the Argo Data Management Team (ADMT) meeting that followed a month later and where these issues were discussed at length
Summary
The Biogeochemical-Argo (BGC-Argo) Program aims at operating a network of profiling floats equipped with sensors of key biogeochemical variables for supporting research activities that address impacts of climate change on oceanic biogeochemical cycles and ecosystems (Claustre et al 2010; IOCCG 2011; Johnson et al 2009). Similar to Argo, this is a coordinated, voluntary, distributed, and multinational network of profiling floats, but with a significant addition of sensors. The global network is progressively maturing through a cluster of national projects, e.g. the French SOCLIM project (http://soclim.com), United States’ SOCCOM project (http://soccom.princeton.edu), South Africa’s SOCCO BIO-ARGO project Org.za/research/#Bio-optics), and Chinese ReMOCA project in the Southern Ocean; the European REMOCEAN project (http://remocean.eu) and Japanese INBOX project (http://www.jamstec.go.jp/ARGO/inbox) in the subtropical gyres; the United States’ NAAMES project More than 15 participants were invited, which included members of the international BGC-Argo steering committee (from Australia, Europe, France, the UK, US, and China), national Argo project representatives from China, manufacturers of floats, sensors, and batteries, as well as other oceanographers and remote-sensing scientists who are interested in Biogeochemical-Argo float data
