LISST Measurements from Ocean Alkalinity Enhancement (OAE) Joint Learning Opportunity (JLO) in Halifax

The two datasets below were collected during our participation in the OAE JLO in Halifax, Nova Scotia, Canada from September 2024 to March 2025 where our sensors were deployed throughout an OAE field trial being led by Planetary Technologies and Dalhousie University. For more information about our work under the JLO, see our dedicated project page here: Ocean Alkalinity Enhancement Joint Learning Opportunity in Halifax.
