CISESS at the 2026 Ocean Sciences Meeting

The AGU Ocean Sciences Meeting was held 22–27 February 2026 in Glasgow, Scotland, UK. CISESS Scientist Annika Jersild gave a talk on 27 February titled "Analyzing the Impact of Observational Sources on Air-Sea CO₂ Flux Uncertainty Using Machine Learning", highlighting the influence of data scarcity on the uncertainty in machine-learning systems. She and co-authors from NOAA AOML and Flanders Marine Institute found that variations in observational system sources can cause some regional influences but have a minimal impact on the estimates and uncertainty at global scales (especially when compared to the bias and uncertainty stemming from regions of no data). Jersild has been leading a CISESS Project to update the Carbon Budget and this work has just been released by the ICOS Carbon Portal (see Figure 1).

On 26 February, CISESS Scientist Hyelim Yoo presented a poster describing “Modernizing Access to NOAA Fleet Data: Metadata Integration, NetCDF Standardization, and Cruise Catalog Improvements.” One enhancement announced was the conversion of Scientific Computer System (SCS) data to netCDF, facilitating streamlined data accessibility for end users and integration into NCEI's suite of data products. The Data Assembly Center also completed the development of a programmatic framework for generating cruise-level metadata records, ensuring that every cruise-level record is populated with high-fidelity spatiotemporal context and standardized project identifiers to maximize data discoverability. New data streams to add to the NOAA Ship Cruise Catalog are in the works, such as Conductivity, Temperature, Depth (CTD) sensor data submitted by OMAO.

From moderating and presenting at a Town Hall with the theme of “Establishing an International Program to Deliver Sustained Open-Ocean Biological Data” to contributing to several poster and oral presentations to being recognized by The Oceanography Society (TOS), it was a busy week for CISESS Consortium Scientist Adam Martiny from University of California Irvine at this year’s Ocean Sciences Meeting. Martin and the international Bio GO-SHIP team were the recipients of the TOS Ocean Observing Team Award, in recognition of 20 years of internationally coordinated, high-quality, high-resolution repeat hydrographic measurements, documenting decadal changes in ocean circulation, heat, carbon, oxygen, and nutrients essential for understanding Earth’s climate.
