Abstract
Abstract Ice accretion has detrimental effects on a wide range of sensitive engineering structures, especially those adjacent to or within the ocean. Here the effect of salinity on the adhesion of ice to different surfaces is investigated over a range of sub‐zero temperatures. The saline ice adhesion strength is found to decrease with the increasing salinity on all surfaces tested. The presence of thermodynamically stable brine at temperatures above −21.2 °C is found to drastically lower the saline ice adhesion strength of essentially all surfaces through a lubrication effect. At −25 °C, below the eutectic temperature between H 2 O ice and hydrohalite (NaCl 2H 2 O), high adhesion is observed. For smooth surfaces, hydrophobicity is effective at lowering the saline ice adhesion strength, and a hydrophobic silicon wafer exhibited a saline ice adhesion strength of 2.4 ± 1.8 kPa at −10 °C with 1 wt% NaCl. The adhesion of real frozen seawater differed from the NaCl solutions, where an adhesion strength ≈12 kPa is observed even at −25 °C. Given the strong adhesion of ice to marine infrastructure, the results here demonstrate how temperature, salinity, and surface characteristics must be considered when designing materials that can mitigate the icing of marine infrastructure and vessels.

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
