Western Great Lakes Section of the St. Lawrence Seaway
Bibliographic record
Abstract
The St. Lawrence Seaway connects Lake Superior, Lake Huron, Lake Michigan, Lake Erie and Lake Ontario to the Atlantic Ocean. The lakes and connecting rivers, St. Mary’s, St. Claire, Detroit, Niagara and St. Lawrence, have been a major artery for transportation, migration and trade. The Great Lakes have been sailed for trading and commercial purposes since at least the 17th century. Approximately 6000 ships have sunk, killing more than 30,000 sailors and passengers. The linkage of Lake Michigan to the Mississippi River has allowed Chicago’s wastewater to be disposed of into the tributaries of the Illinois River and Mississippi River to avoid contaminating Lake Michigan, the source of Chicago’s drinking water. An unintended consequence of linking the Western Great Lakes basin with the Mississippi River basin was the creation of the wet pathway (Chicago Sanitary and Ship Canal) through which the flying Asian carp is trying to use to get into the Great Lakes. An electric fish barrier was constructed on the Chicago Sanitary and Ship Canal to prevent the carp from migrating into Lake Michigan, the Great Lakes basin and the St. Lawrence Seaway. The primary objective of this paper is to document the environmental threats to the Western Great Lakes basin, which has only one natural outlet, the Detroit River, which flows naturally into Lake Erie. These environmental challenges which are starting to requiring mitigation including the impact millions of people living in the Western Great Lakes basin, navigation on the St. Lawrence Seaway, thousands of shipwrecks at the bottoms of Lake Huron, Lake Superior and Lake Michigan, disposal of treated and untreated industrial and urban waste into the lakes, pollution of the sources of drinking water, land use change, shoreline erosion, building structures on the shoreline banks, underwater oil and gas pipelines, invasive species including Asian carp, and record high Western Great Lake water levels. The Western Great Lakes shorelines are actively eroding partly because of the high surface water levels. The high-risk erosion areas have been retreating at an average rate of 30 cm per year for the last 15 years.

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.
