Confirmation of green turtle (Chelonia mydas) foraging grounds in northern New Zealand
Bibliographic record
Abstract
The green turtle (Chelonia mydas) is the only sea turtle species to reside year-round in New Zealand waters, with juveniles using shallow coastal habitats as foraging grounds before dispersing throughout the Pacific. Rangaunu Harbour in northern New Zealand was surveyed in the austral summer to assess the feasibility of aerial drones for monitoring green turtles. Across 163 km of drone transects, 27 turtle sightings representing potentially 18 unique individuals were recorded, predominantly in shallow seagrass (Zostera muelleri novozelandica) habitats during high tides. Five green turtles were observed actively foraging on floating seagrass and among the subtidal seagrass beds. These sightings provide visual confirmation that the harbour is a temperate neritic foraging ground for green turtles in New Zealand. The survey also documented diverse marine fauna, including eagle rays (Myliobatis tenuicaudatus), stingrays (Bathytoshia spp.), and several teleost species, confirming the feasibility of drones as a monitoring tool for turtles and other marine megafauna. Anthropogenic pressure to estuaries and coastal New Zealand ecosystems, including Rangaunu Harbour, highlight the need to identify and protect critical green turtle habitat in New Zealand waters as soon as possible. Further drone surveys in nearby harbours are feasible and recommended to locate additional foraging areas for green turtles across northern New Zealand.

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.
