OCB will support participation in Cornell Summer Satellite Remote Sensing Workshop

Posted by mmaheigan 
· Wednesday, March 25th, 2026 

OCB will support participation in Cornell Summer Satellite Remote Sensing Workshop
June 1 – June 12, 2026, Cornell University, Ithaca New York

The Cornell Summer Satellite Remote Sensing Workshop is being offered once again this year. The workshop is highly methods-oriented and intended to give participants the practical skills needed to work independently to acquire, analyze and visualize large data sets derived from a wide range of ocean satellite sensors.

Strong emphasis is given to ocean color remote sensing and the use of NASA’s SeaDAS software to derive mapped imagery of geophysical parameters using satellite data derived from the most popular ocean color sensors.  Pre-written python scripts will be used in conjunction with SeaDAS to enable processing large quantities of ocean color data from Level-1 to Level-3.  In addition, the workshop will address the acquisition and use of Level-3 satellite data products for sea surface temperature, ocean wind speed and sea surface height.

A central goal of the course is to develop good python programming skills that are needed to make effective use of satellite data to routinely monitor ocean conditions, gain new insights into ocean dynamics, and to rigorously test new hypotheses.  Participants will work with both Jupyter Notebooks and executing python scripts from the Unix Terminal.

For more information about the training workshop content and enrollment process:
Visit: http://oceanography.eas.cornell.edu/satellite
Email: Bruce Monger

OCB will provide tuition, housing, and a travel stipend for up to 4 US-based participants in this training course. Please send the following materials in a single formatted PDF file to hbenway@whoi.edu by April 13:

1) Abbreviated (2 pages max) CV 
2) 1-page statement of interest about how this course would benefit your education, research, and/or professional goals. 

Applications will be reviewed the week of April 13, and applicants will be notified the week of April 20.

New unified interface for existing ocean carbonate chemistry data products

Posted by mmaheigan 
· Tuesday, March 24th, 2026 

The paper provides a comprehensive synthesis of 68 existing ocean carbonate chemistry data products and data product sets, including cruise-based compilations, time-series datasets, gap-filled observational products, and model-based reconstructions. The authors highlight the diversity of available products, noting differences in spatial coverage, temporal resolution, methodologies, and intended scientific applications. By systematically cataloguing and comparing these datasets, the study helps researchers identify which products are most suitable for specific scientific questions related to ocean carbon cycling and ocean acidification.

EXTENDED Nominations for new OCB Subcommittee Ocean Carbonate System Intercomparison Forum (OCSIF)

Posted by mmaheigan 
· Thursday, March 12th, 2026 

We are currently seeking nominations for members of a newly established OCSIF topical subcommittee of the OCB SSC – the Ocean Carbonate System Intercomparison Forum (OCSIF). This subcommittee has its origins in the OCB OCSIF working group focused on identifying and addressing uncertainties in the seawater carbonate system and increasing measurement inter-comparability, with goals of advocating for and sparking collaborations to address these issues and providing guidance for data reporting and documentation while fostering engagement across career stages and global participation. We aim to include a range of expertise and career stages, including very early career scientists (0-4 years since PhD). Non-US applicants are encouraged to apply, as we will aim to include at least 1-2 non-US members on the subcommittee at all times. The subcommittee will include up to 15 members. We are seeking a range of expertise pertaining to the ocean carbonate system, including:

  • Ocean carbonate system measurements (pH, total alkalinity, dissolved inorganic carbon, and pCO2)
  • Carbonate system reference material/metrology
  • Ocean carbonate system calculations, software, and modeling
  • Ocean carbonate system autonomous sensors
  • Data product development
  • Organic acids and organic alkalinity
  • Ocean acidification
  • Inorganic carbon cycling
  • Marine carbon dioxide removal
  • Marine physical chemistry
  • Coastal and estuarine carbonate cycling

Nominations to the OCB Project Office by March 27, 2026 (closed). Self-nominations welcome and encouraged!

OCB subcommittee membership terms are typically ~2-4 years, but a detailed charge and terms of reference for this new subcommittee will be established by its inaugural members. The inaugural co-chairs of this subcommittee will be Ryan Woosley (MIT) and Katelyn Schockman (U Miami/NOAA). The OCB Project Office will oversee the nomination and election process. Discussion of nominees and scoring via electronic ballot will be carried out by a small committee of subject matter experts, including Ryan and Katelyn.
