RISE Project: Coastal CTD Profiles from Undulating Tow

July 2004 to June 2006 data were collected on the continental shelf off Oregon and Washington via a towed, undulating CTD platform. Transects range from a few kilometers to over 60km, with profiles from the surface to depths of 40-60 meters. The dataset likely contains physical oceanographic measurements such as conductivity, temperature, depth, and dissolved oxygen.

Use Cases

• Analyzing cross-shelf gradients in water properties based on transect data.
• Studying temporal variability of coastal hydrography over three summer field seasons.
• Calibrating satellite-derived ocean color data with in-situ profile measurements.
• Modeling river plume dispersion and mixing on the continental shelf.

Strengths

• Provides multi-year temporal coverage across three distinct field campaigns (2004-2006).
• Offers high spatial resolution via continuous, undulating towed transects up to 60km long.
• Cross-platform presence on datagov and nasa_earthdata signals established curation and importance.

Limitations

• Key metadata conflicts: last_updated dates differ significantly between platforms (2006 vs 2026).
• Metadata completeness is low: row counts, file size, license, and author are not provided.
• Column details are sparse; the full variable list and data quality flags are not described.
