Your input needed: biology’s role in ocean carbon storage

Posted by mmaheigan 
· Monday, November 7th, 2022 

You are invited to take part in a community-wide survey to identify knowledge gaps in understanding biology’s role in ocean carbon storage.
The survey forms part of the BRICS project which aims to identify the gaps in our understanding, and highlight model limitations, which result in uncertainty in contemporary and future ocean carbon storage.
The survey results will be used to inform later fieldwork campaigns and model development as part of a larger programme (BIO-Carbon) funded by the UK’s Natural Environment Research Council.
The survey will take about 15 minutes to complete and all responses are anonymous.  The survey will remain open until 5th December.
Thank you for your participation.  The survey can be found here: https://plymouth.onlinesurveys.ac.uk/brics-final
Please feel free to pass the survey link on to anyone in your network.

The Carbon Dioxide Removal (CDR) Academy

Posted by mmaheigan 
· Friday, October 28th, 2022 

Carbon Dioxide Removal (CDR) is a hot topic right now – there have been a flurry of various activities recently1. As a community of practice focusing on carbon cycle science in North America and adjacent oceans, NACP is poised to make significant contributions in this arena as new programs are initiated and existing CDR activities expand and grow. Perhaps the most relevant area for NACP engagement is the development and implementation of robust measuring, monitoring, and verification (MMRV) for CDR activities, and we are planning an in-depth workshop on this topic in early 2023.

However, we recognize that CDR as a conceptual framework and practice may be relatively novel for many in the NACP community. Thus we are offering a “CDR Academy” that will offer introductory material on the basics of CDR in different Earth systems, including:

A curated list of introductory resources (reports, videos, articles, etc.) on CDR

A series of 1-hour webinars on CDR in different ecosystems/contexts, such as oceans and coasts, geological reservoirs, natural and working lands, and the atmosphere. These webinars will be recorded for future viewing and reference.

A panel discussion with webinar presenters discussing cross-cutting themes, research needs, and potential opportunities for collaboration.

Building a Cost-effective Coastal Biogeochemical Observing Network in Collaboration with the Commercial Fishing Community

Posted by mmaheigan 
· Friday, September 23rd, 2022 

OCB Scoping Workshop:
Jan 18-20, 2023 (Woods Hole, MA)

This 3-day scoping workshop will initiate a dialog among key stakeholders and collaborators across the commercial fishing community, federal and state governments, technology companies, and academia to focus on building a cost-effective, coastal biogeochemical (BGC) observing network. Existing data coverage often lacks the spatial and temporal resolution to characterize key processes in dynamic coastal systems. What is needed is a more sustainable model for collecting high-resolution data, including BGC data, at a significantly lower cost that can provide improved spatial and temporal coverage. Fishing activities are uniquely well suited for such a sustainable model. A fishery-based BGC coastal observing network will provide data products that directly benefit fishing operations, marine resource management, coastal research, climate change mitigation, the Blue Economy and beyond. Building on decades of collaboration with the commercial fishing industry, this workshop will provide a platform to share diverse stakeholder perspectives and end goals, learn about new and emerging observing capabilities and technologies, and discuss viable approaches to establish a fishery-based BGC observing network. If you are interested in remaining informed about this workshop (e.g., receiving notification when registration opens), please fill out the brief expression of interest form (this doesn’t commit you to attend). If you have questions about the scope of the workshop, please contact lead organizer Z. Aleck Wang.

The workshop will provide 15 honorary stipends of $500 to fishing community participants.

The first webinar of this series was held on March 30th, 10-11 am Pacific/1-2 pm Eastern. It will covered the current status of BGC floats worldwide, projected float deployment locations, and tools that we have developed to streamline data access, followed by community discussion and Q&A.

  • Introduction to the GO-BGC webinar series (Yui Takeshita, MBARI)
  • Introduction to BGC-Argo and GO-BGC (Alison Gray, University of Washington)
  • Upcoming float deployment plans (Yui Takeshita, MBARI)
  • How to use BGC-Argo data? (Jonathan Sharp and Hartmut Frenzel, NOAA PMEL)
  • What is the quality of BGC-Argo data? (Yui Takeshita, MBARI)
  • Discussion and community Q&A

GO-BGC Webinar Series Overview
Hundreds of Biogeochemical (BGC) profiling floats have been deployed worldwide, and the number of floats is expected to continue to increase in the coming years. Specifically, the Global Ocean Biogeochemistry Array (GO-BGC) is a NSF Mid-Scale Research Infrastructure project that is funded to deploy 500 BGC floats globally over the next 5 years. We expect additional significant contributions from other US and international institutions, which will build towards a sustained global array of BGC-Argo floats.

The quality-controlled, freely available data from these floats are transforming our capacity to observe, quantify, and understand ocean biogeochemical processes and how they are responding to anthropogenic pressures (e.g., acidification and deoxygenation). With improved constraints on the biological carbon pump and air-sea CO2 exchange, these data sets will also inform marine ecosystem management and decision making.

This webinar series, hosted by GO-BGC and the OCB Project Office, aims to build and support a growing community of biogeochemical float data users. As the BGC-Argo array matures and expands its global coverage, so will the potential for scientific discovery. We hope that the applications and research findings highlighted in this webinar series will demonstrate the potential for these globally distributed datasets and inspire the community to explore novel applications, scientific questions, and new collaborations in the use of BGC-Argo data.

Webinars will be hosted roughly quarterly. Subsequent webinars will focus on scientific or geographic themes. We will highlight emerging research results based on BGC-Argo data, and aim to promote early career researchers. All webinars will be recorded and made available through the OCB and GO-BGC websites.
