This dataset was collected under a Joint Learning Opportunity (JLO) funded by Carbon to Sea and COVE. The sensor was deployed to provide direct, in-situ measurements of particles and particle properties (e.g., size, concentration) to (1) address open questions related to alkaline feedstock transport and fate, as well as environmental impacts from alkalinity dosing (e.g., secondary precipitation), and (2) support the refinement and validation of models used to predict alkaline feedstock transport and dissolution kinetics. The LISST-200X was profiled at different locations and times throughout the Bedford Basin and surrounding waters from September 2024 to March 2025, both in and out of the mixing zone where alkalinity was being dosed. Profiling was performed during the approximately biweekly boat surveys conducted throughout the trial. The sensor measured particle size distribution, mean particle diameter, volume concentration, beam attenuation, and other variables. Additional information about the sensor deployment, profile locations, measurement parameters, data format, and processing can be found in the included supplemental document. This dataset is available to the public for a wide variety of uses including scientific research and analysis.
