Abstract
Coastal vegetated ecosystems are recognized for their role in cycling and storing carbon in the world’s oceans (i.e., blue carbon); however, high uncertainty in carbon sequestration rates are driven in part by an absence of studies directly estimating carbon export to the deep sea. We modeled export from nearshore kelp forests and seagrass beds, showing that export varies by orders of magnitude across spatial scales (5 – 100s km), kelp and seagrass species, seasons, and forms of carbon, raising caution in using generalized export rates in blue carbon accounting. Our results are also the first to show rapid (within 20-30 days) and extensive export of neutrally buoyant dissolved organic carbon to the shelf break (up to 44% within 90 days), contrasting sinking particulate organic carbon particles that remained within 100 m water depth in the near shore. These results improve estimates of carbon sequestration by nearshore vegetated ecosystems and reveal contrasting patterns of export relative to other regions of the globe.

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 it
