Marsh Recession and Erosion study of the Fraser Delta, B.C., Canada from Historic Satellite Imagery
Bibliographic record
Abstract
<p class="MsoNormal">The goal of the study is to map the changes of marsh extent and topography on both Sturgeon Bank and Westham Island between 1980 and now. The study will look for a correlation between the recession and the possible loss of sediment from the banks. If a sediment deficit is a (major) contributor of marsh recession within the Fraser Delta, the results of the study should reveal such a connection.</p> <p class="MsoNormal">Although there are plenty of studies suggesting changes have taken place in the marshes fronting the Fraser Delta, no study has utilized the extensive data record of satellites to study these changes for the entire Fraser Delta. Tools like the Aquamonitor can detect the changes in coastlines in the past 30 years from satellite imagery. More advanced tools are still in development like MI-SAFE, which detects inter-tidal elevations and vegetation on foreshores to estimate the potential risk reduction of flooding by coastal vegetation all across the world. Within the study the latest techniques from these tools are applied and adapted to the Fraser Delta. By using the full 30+ years of information on satellite imagery, the marsh and inter-tidal surface changes are examined from a new angle.</p>

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
