8th WMO Workshop on the Impact of Various Observing Systems on Numerical Weather Prediction and Earth System Prediction
2024-05-27 - 2024-05-30 | Norrköping, Sweden
The 8th WMO Workshop on the Impact of Various Observing Systems on Numerical Weather Prediction (NWP) and Earth System Prediction (ESP) will be organized by WMO and will be hosted by the Swedish Meteorological and Hydrological Institute (SMHI) in Sweden, at the SMHI main office in Norrköping, on 27-30 May 2024. Participation from all the major numerical weather prediction (NWP) centers and communities active in the field of impact studies about the observing systems is anticipated. The Workshop will be held in a hybrid format (in-person and remote participation will be enabled), and will be conducted in English.
WMO’s Impact Workshop series is an important quadrennial venue for providing science evidence on the impacts of surface and space-based observing systems, on short to medium and longer-range forecasting including climate monitoring. Conclusions from the Workshop provide guidance on how to optimize the use of the current global observing system as well as help guide its future evolution.
This 8th Workshop will continue to focus on assessing the impacts of various observing systems in all Earth system domains on NWP, but will extend the scope to also encompass the impact assessment of the various observing systems, to other Earth system applications. This is done in order to achieve a comprehensive understanding of the value of the observations and to support the strategic goals of WMO.
Experts who have results of impact assessment of various observing systems, especially those responding to the science questions, are invited to submit a short abstract. Contributions to the Workshop may fall within general topics that will frame the Workshop sessions (to be determined at a later stage), or they may simply address one or several of the specific studies and science questions. Note that to increase the chances of being responsive to this call, abstracts should clearly articulate what type of impact assessment(s) will be presented.
Abstract submission deadline is December 15, 2023.

GO-BGC Science Webinar: High-Latitude Biogeochemistry
2024-05-09 10:00 - 12:00 (America/Los_Angeles)
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 high-latitude ocean biogeochemistry by exploring the research of two groups that participated in the 2023 GO-BGC/BGC Argo Float Data Workshop at the University of Massachusetts Boston. 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 and A session. Recordings will be available on the OCB and GO-BGC websites.
Webinar agenda:

An update on the GO-BGC program,Yui Takeshita (Monterey Bay Aquarium Research Institute, USA).
Biogeochemical properties of the Lofoten Basin Eddy from 14 years of BGC-Argo float data, Daniel Koestner (University of Bergen, Norway). Oceanic eddies are typically short lived but are a crucial physical phenomenon supporting heat and nutrient exchanges across water bodies. The Lofoten Basin Eddy (LBE) is a seemingly permanent topographically constrained anti-cyclonic eddy situated in the northern Norwegian Sea containing relatively cool surface waters and consistently warmer subsurface waters. As such, the conditions in the LBE may drive significantly different biogeochemical processes than the surrounding waters. Here we examine the unique biogeochemical signatures of the LBE with the 14-year timeseries of BGC-Argo float observations. We describe methodology for float-eddy colocation and examine differences in key biogeochemical parameters inside and outside of the eddy, including organic carbon export.
Lessons and opportunities from the Southern Ocean Sea Ice team at the 2023 GO-BGC Float Data Workshop, Sophie Shapiro (University of California San Diego, USA). In the winter of 2023, the Southern Ocean reached a record low sea ice extent anomaly. This unprecedented low sea ice coverage coincided with the August convening of the GO-BGC float data workshop. What insights could a cohort of motivated researchers uncover with two working days and the BGC Argo dataset? In this talk, we present preliminary data from BGC floats deployed in the Southern Ocean marginal sea ice zone. We illustrate the potential of the observational network to investigate further questions about the dynamics and impacts of changing sea ice. Finally, we highlight insights and challenges from the GO-BGC workshop to demonstrate the further potential of collaborative data working groups.

EARTH uses near-real-time data from ocean observatories to design and test outreach with the Internet as an interface to scientists, teachers, students, and the public.
The 2022 workshop will be held in Seattle, WA, 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.
Because we only have a limited number of spots available in each EARTH workshop, applications are required. Applications, including all supporting materials, are due by 8:00 pm PST on February 7, 2022 for the summer workshop. The application process is outlined on the MBARI website: mbari.org/EARTH
Teachers involved in this workshop will:

Explore cutting edge marine science and technology, ocean observatories and the data that they collect
Examine current scientific studies that use oceanographic data and how that data has changed our way of thinking about the oceans
Develop new curriculum that uses real science and near-real-time data to teach science content and process and addresses their needs and the needs of their students
Be part of a program that integrates the use of near-real-time data and real science into classrooms at a national level
Experience a rich opportunity for professional collaboration and receive classroom resources, housing, and travel allowance (exact amounts will depend on the number of teachers signed up for the workshop). We ask that the participants arrange their own travel; reasonable costs will be reimbursed.
Discuss how new curriculum materials can be developed that use virtual reality, augmented reality, and/or distance education to teach science content and process and address the needs of educators and their students

AGU Fall Meeting Town Hall
2020-12-16 07:00 - 08:00 | Virtual Meeting
Current and Future Biogeochemical–Argo Programs and Planning, TH096
Wednesday, 16 December 2020, 7:00 – 8:00 AM PST (10:00 – 11:00 EST) The ocean provides critical services to life on the planet, absorbing 93% of the heat from anthropogenic warming and a quarter of human CO2 emissions each year. Yet these services come at a price: ocean temperatures rise, pH and oxygen levels fall, currents change, nutrient concentrations shift. Long-term investments of government agencies and private foundations have produced a set of key BGC sensors to track these changes and their impacts on biogeochemical cycles and carbon dioxide uptake. Argo profiling floats equipped with BGC sensors can operate for years, observing the distributions of chemical and biological properties from 2000 m depth to the surface. The NSF-funded Southern Ocean Carbon and Climate Observations and Modeling (SOCCOM) program has deployed over 180 BGC floats since 2014, has developed BGC state estimation, and has applied float results to new understanding of the Southern Ocean’s role in BGC cycles; this has been central to growing modeling and model analysis components. The success of this program, with some 100 peer-reviewed papers and multiple Ph.D. theses, demonstrates that the major operational challenges for a global, international BGC-Argo network have been overcome. Success of the SOCCOM program has led to funding of the Global Ocean Biogeochemistry (GO-BGC) Array by the US NSF. GO-BGC will deploy an additional 500 BGC profiling floats throughout the world ocean. In combination with extensive international efforts, an array of 1000 profiling floats in waters deeper than 2000 m will be established. In this Town Hall for the entire oceanographic community, we will review past efforts and future plans for the BGC-Argo program. The success of the BGC-Argo observing system development rests on strong science goals and funded science analysis – we seek community input on issues ranging from data access to mechanisms to interact with process oriented science projects.
