This deposit contains the full reproducibility package for the preprint reporting a statistically anomalous, multi-variable oceanographic and atmospheric signal in the southeastern Indian Ocean (37°S–39°S, 89°E–94°E) on the 7th Arc — the satellite-derived boundary along which Malaysia Airlines Flight MH370 is believed to have exhausted its fuel on March 8, 2014. Unlike previous MH370 search efforts that modeled flight paths, debris drift, or acoustic signals, this analysis asks a different question: did the ocean itself record something anomalous at the time and place of the disappearance? Treating the water column as a passive recorder of perturbation, the study applies the domain-agnostic Cross-System Signal Recognition / Dynamic Adaptive Staging (CSSR/DAS) architecture (U.S. patent application filed April 28, 2026, BG4K LLC) to twelve independent variables from five NASA platforms using publicly available Giovanni data. The analysis identified a convergent anomaly characterized by elevated dissolved organic matter (CDOM +6.13%), diffuse light attenuation (Kd490 +4.45%), chlorophyll-a (+4.41%), and particulate organic carbon (+2.77%), accompanied by a spectrally coherent blue-band suppression and green/red-band elevation in the visible reflectance record. Leave-one-out Z-score analysis across the full 21-year MODIS-Aqua record confirmed 2014 as a clear outlier at this location (chlorophyll-a Z = +4.32, rank #1 of 21; POC Z = +3.48, rank #1; Kd490 Z = +3.36, rank #1). A 30-year sea-level anomaly climatology showed March 2014 was unremarkable (Z = +0.72, rank 9/30), ruling out anomalous eddy activity as the primary driver. This deposit includes the complete preprint, verified Table 2, step-by-step Giovanni reproducibility appendix, click-ready URLs, and all supporting plots. The author (a systems researcher, not an oceanographer) presents these findings strictly as an anomaly for independent expert review, replication, and potential falsification — not as a conclusion or confirmed aircraft location. All data are publicly available via NASA Giovanni (giovanni.gsfc.nasa.gov). Expert critique and replication attempts are actively welcomed.
