Facts you can trace.
Download the same normalized records shown on the site, with units, source links, and original timestamps.
What the export contains
Destination identifiers and coordinates, measurements and units, source status, report or observation time, collection time, source links, forecast and tide context in JSON, and known collection limitations. The CSV is a flat table of primary measurements with their provenance.
Historical records
Each published source bulletin includes a snapshot download. Historical figures retain their dates; an old snapshot must not be presented as current conditions.
Attribution and reuse
Cite the original provider for its measurements and Shredminder for this compilation, normalization, or original comparison. Include the source date and the destination or bulletin URL. Upstream provider terms continue to apply; this page does not grant a blanket license over third-party material. Contact the publisher about bulk reuse or syndication.
