Abstract: Description This replication package supports the manuscript: Dorado, J.A., Cabacas, R.A., Concepcion, M.B.S., Dayot, R.V.J.,Deocampo, N.J.E., and Sandig, S.D.E. Reconstructing observationopportunity in sparse satellite vessel-detection archives: recoveredzero-detection records, monitoring gaps and spatial prioritisation inthe Philippine exclusive economic zone. The package contains the code, derived analysis data, output tables, figure-datafiles, figures, data dictionary, source-data query specifications, downloadmanifests, and SHA-256 checksums required to reproduce the study’s results. The study reconstructs observation opportunity from Sentinel-1 acquisition metadatato distinguish cell-months with no satellite acquisition from acquisition-coveredcell-months with no returned vessel detection. It analyses SAR vessel detections andAIS-derived vessel-presence data for the Philippine exclusive economic zone from2017 to 2025. Raw Global Fishing Watch and Copernicus Sentinel-1 source records are not includedunless redistribution is permitted by the relevant provider terms. The archivecontains the exact retrieval queries, data-source documentation, manifests, andchecksums needed to re-obtain and verify source inputs. Contents code/ — analytical scripts and reusable functions derived_data/ — derived analysis-ready data, where redistribution is permitted outputs/ — output tables, figures, and figure-data files metadata/ — source queries, download manifests, checksums, and data dictionary docs/ — study documentation and reproducibility instructions README.md — package overview and step-by-step reproduction guide Reproducibility The analyses were conducted in Python 3.11 using reproducible command-line scripts.The package includes validation outputs documenting the integrity of raw-downloadmanifests, the analysis-panel structure, count reconciliation, spatial-referenceconsistency, and the separation of development and held-out validation periods. Status This is Version 1.0.0 of the replication package associated with a manuscriptsubmitted for peer review. If the manuscript is revised, an updated Zenodo versionwill be released with revised files and linked version metadata.
