2024 MATE World Championship
2024-06-20 - 2024-06-22 | Kingsport, TN
The MATE ROV Competition is an annual underwater robotics (aka remotely operated vehicle or ROV) challenge that engages a global community of learners. From expanding the Global Ocean Observing System to protecting and restoring ecosystems and biodiversity, and unlocking ocean-based solutions to climate change, the 2024 competition mission tasks focus on solutions that include ocean observing assets for data collection, reimagining the utility of telecommunications cables, administering probiotics for diseased coral, identifying healthy habitats for lake sturgeon, and deploying GO-BGC floats to monitor ocean health.
For 2024, the MATE ROV World Championship event (June 20-22, 2024), will be one of the largest and most internationally diverse yet! 82 teams from 17 different countries will be converging in Kingsport, Tennessee to put their underwater robotics skills to the test. Teams will be traveling from near and far to compete, including the United States, Canada, Scotland, Mexico, United Arab Emirates, Italy, Poland, Germany, Turkey, Macau, Hong Kong, China, Egypt, Saudi Arabia, and Singapore.

2024 EARTH Workshop
2024-06-24 - 2024-06-28 | University of Washington, Seattle, WA, United States
The 2024 EARTH workshop will be held June 24-28 in Seattle, WA, and is being co-hosted by the Global Ocean Biogeochemistry Array (GO-BGC), a project funded by the US National Science Foundation to build and deploy a global network of chemical and biological sensors that will monitor ocean health. This new network of floats will collect data on the chemistry and the biology of the ocean from the surface to a depth of 2,000 meters, and will allow scientists to pursue fundamental questions concerning ocean ecosystems, observe ocean health and productivity, and monitor the elemental cycles of carbon, oxygen, and nitrogen in the ocean through all seasons of the year.
During this workshop, educators work with active researchers to explore current science and/or engineering research, data, and conclusions. The educators are given time to develop their own curricula using the knowledge from these explorations and their own experiences to create classroom lessons tied to the abilities of their own students as well as current education standards and pedagogy. The teachers also develop connections with each other and with the researchers that assist them in expanding their classroom reach across the country.
Teachers involved in this EARTH workshop will:

Cultivate relationships with local researchers and like-minded educators that can lead to future collaborations

Explore available resources from supporting organizations and programs, such as GO-BGC and MBARI, and develop institutional connections that can aid in future lessons

Receive a Certificate of Participation that provides evidence of 40 hours of professional development that can be used toward continuing education or certificate renewal

Develop new curriculum resources that use real science and authentic data to teach science content and process and address their needs and the needs of their students

BGC Argo Webinar #8: Comparing BGC-Argo observations with models
2024-10-16 11:00 - 12:00
Register for October 16 Webinar

Please join us for the quarterly GO-BGC webinar, hosted by the US Ocean Carbon and Biogeochemistry Project Office. This webinar will be focused on comparisons between BGC-Argo observations and ocean model simulations focusing on bbp and particulate forms of carbon. The webinar will begin with an update on the status of the GO-BGC float array, followed by two short presentations. We’ll then close with a community discussion and Q&A session. Recordings will be available on the OCB and GO-BGC websites.
1) Yui Takeshita (Monterey Bay Aquarium Research Institute, USA, yui@mbari.org): An update on the GO-BGC program
2) Camila Serra-Pompei (Technical University of Denmark): Assessing the potential of backscattering as a proxy for phytoplankton carbon biomass
The particulate backscattering coefficient (bbp) has often been used as an optical proxy to estimate phytoplankton carbon biomass (Cphy). However, total observed bbp is impacted by phytoplankton size, cell composition, and non-algal particles. The scarcity of phytoplankton carbon field data has prevented the quantification of uncertainties driven by these factors. Here, we first review and discuss existing bbp algorithms by applying them to bbp data from the BGC-Argo array in surface waters (<10m) and show that errors can be large when the bbp signal is low. Next, we use a global ocean circulation model (the MITgcm Biogeochemical and Optical model) that simulates plankton dynamics and associated inherent optical properties to quantify and understand uncertainties from bbp-based algorithms in surface waters. In an ideal world where field data has no methodological uncertainties, the model shows that bbp algorithms could estimate phytoplankton carbon biomass with an absolute error close to 20% in most regions.
3) Martí Galí Tàpias (Institute of Marine Sciences [ICM-CSIC], Spain): Constraining stocks and fluxes of Particulate Organic Carbon (POC) through the comparison between particulate backscattering measurements and the PISCESv2 model
BGC-Argo data offers a great opportunity for model evaluation, optimization, and the development of improved parameterizations, ultimately furthering our mechanistic understanding. However, comparison between BGC-Argo observations and models requires careful consideration of the spatiotemporal scales that each of them can resolve. When using particulate backscattering (bbp) as a proxy for particulate organic carbon (POC), additional attention must be paid to the variability in the POC/bbp ratio, its uncertainty, and its underpinning biogeochemical drivers. In this talk I will present comparisons between bbp from BGC-Argo and simulated POC based on both 3D (Eulerian) and 1D (pseudo-Lagrangian) frameworks. I will discuss the potential and limitations of model parameter optimization using BGC-Argo bbp as the observational reference. Finally, I will explore the impacts of optimized model parameters on mesopelagic POC budgets and vertical fluxes in the PISCESv2 model.

PICES 2024 Annual Meeting
2024-10-26 - 2024-11-01
The Future of PICES: Science for Sustainability in 2030, Honolulu, Hawaii, USA
PICES has provided leadership in developing a more thorough understanding of the structure, function, and changes of North Pacific marine ecosystems with the support of its flagship scientific programs. We now embark on the “FUTURE” of PICES that will lead to better observations, improved awareness of mechanisms of change, and ultimately science for sustainability by 2030. Through our science PICES will continue to provide leadership to the United Nations Decade of Ocean Science for Sustainable Development and the mission of developing “the science we need for the ocean we want”. We welcome submissions associated with the “FUTURE” of PICES, to explore progress already made and to steer our science towards identifying gaps and setting priorities.
