Abstract

fetched live from OpenAlex

If large liquid or solid water bodies existed in the past in Martian basins such as Argyre, Hellas, and the northern lowland plains, they would have represented massive surficial loads. Earth analogs suggest that the magnitudes of crustal displacements related to water loading and unloading would have varied spatially within and around affected basins. It is likely that the effects of bathymetric irregularities on lithospheric flexure would have caused shoreline areas proximal to deep regions to be depressed (and, subsequently, to rebound) to a greater extent than shoreline areas located near shallow regions. Crustal and mantle inhomogeneities would have likely further contributed to spatial variation in water‐related subsidence and rebound. Simple two‐dimensional elastic flexure models suggest that Martian shoreline features of common age and formed in association with a large ancient water body could vary in elevation today by hundreds of meters as a result of these differential effects. Examples of similar shoreline offsets on Earth suggest that sets of Martian strandline features will reflect the changing nature of loading through time.

Not 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.
