Red Light to Starboard: Recalling the <i>Exxon Valdez</i> Disaster, by Angela Day
Bibliographic record
Abstract
Second, "recalling" focuses upon combined research and storytelling that this author undertook in stages (Preface, p. ix -xii).Third, "recalling" underscores our tendency to observe certain anniversaries.Both 25th and 50th anniversaries predictably stimulate people to review what wisdom has survived, even ripened, from events or discoveries one and two human generations earlier.This book's publication coincided with the 25th anniversary of the night that the supertanker Exxon Valdez ran aground on Bligh Reef on Good Friday, 24 March 1989.An estimated 11 million gallons (42 million litres) of Arctic crude oil escaped through the gash in the tanker's hull, then spread southwestward through Prince William Sound (PWS), and on past the Kenai Peninsula toward Kodiak Island.Just three days after this 25th anniversary, many Alaska residents and geologists worldwide observed the 50th anniversary of Alaska's Good Friday Earthquake of 27 March 1964, which was triggered by rock fractures directly beneath northwestern PWS.Readers who don't already know will learn that Red Light's physical setting is as compelling as its narrative.PWS in southcentral Alaska is geologically, geographically, biologically, and culturally a special place.Perched on the Pacific "Ring of Fire," the Chesapeake Bay-dimensioned Sound has for millions of years been a focus of crustal tectonic movements, by which the dense marine Pacific Plate dives relentlessly beneath one edge of the more buoyant continental crust of the North American Plate.The Chugach Mountains are thrust upward by this crustal subduction, forming the peaks surrounding most of the Sound.Before the Last Glacial Maximum began to relax its grip on Earth some 18 000 years ago, much of PWS was covered by coalescing streams of freshwater glacial ice derived from snow falling on higher elevations in the Chugach Mountains.Now as then, PWS and the Chugach Range sharply demarcate humid northern Pacific marine climates from drier interior terrestrial climates to the north.About 13 -15 000 years ago (130 -150 centuries before present) recession of ice shelves and tidewater glaciers permitted human pioneers from Asia and Beringia to live year round in PWS from its marine and coastal resources.Upon the

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.
