Mission report for the Maritimes Region Atlantic zone monitoring program 2025 Spring Survey (EN728)
Bibliographic record
Abstract
Fisheries and Oceans Canada’s (DFO) Maritimes Region Atlantic Zone Monitoring Program 2025 spring survey was conducted on the Research Vessel Endeavor from March 29 to April 18, 2025. A total of 13 scientific staff participated in the mission and led the deployment of various oceanographic equipment across a network of fixed monitoring stations, including CTD-Rosette deployments for the collection of vertical profiles of e.g., temperature and salinity, and water samples from pre-determined depths, vertical ring net tows for zooplankton sample collection, and Argo float deployments in support of the International Argo program. Additionally, a single passive acoustic monitoring mooring was deployed in Roseway Basin, Scotian Shelf, and a series of acoustic receiver moorings were recovered in the Gully Marine Protected Area (MPA) in support of a DFO-Ocean Tracking Network collaboration to study the movement of tagged species in and around the MPA. In collaboration with the Woods Hole Oceanographic Institution, an Imaging Flow Cytobot was used to collect high-resolution images of phytoplankton from surface waters sampled while underway. This report provides an overview of the mission’s objectives, achievements, gear operations and operational issues. A summary of the seabird and marine mammal observations collected during the mission is presented, as is the vertical structure in temperature, salinity, and dissolved oxygen for each station occupied.
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
