Submarine Groundwater Discharge from Paleochannels?: 'Wonky Holes' on the Inner Shelf of the Great Barrier Reef, Australia
Bibliographic record
Abstract
We report on pockmark-like seafloor depressions, known to the local fishing industry in the Great Barrier Reef (GBR) region as 'Wonky Holes'. Ca. 100 Wonky Holes were identified from a side-scan survey of Halifax Bay, near Townsville on the central GBR shelf. They are depressions with a diameter of 10 to 30m and a depth of up to 4m, and occur in ca. 20m water depth. Wonky Holes resemble pockmarks, known sites of seepage of gas or water from the seafloor, in size and geometry. Seismic transects have revealed that Wonky Holes are associated with riverine/estuarine paleochannels. Preliminary results from salinity and conductivity measurements indicate that fresh groundwater flow may occur from these holes. We propose that submarine paleochannels provide a pathway for groundwater to be discharged into the near-shore zone, provided a connection to an inland hydraulic head exists.

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; both teacher heads agree on what is shown here.
