RR1214 Expedition: Calibrated CTD Salinity Data for NE Pacific Moorings

NE Pacific data from November 2012 consists of processed Conductivity-Temperature-Depth (CTD) casts and water samples collected during research vessel Roger Revelle's transit. The dataset was created to calibrate and validate moored instruments from the Consortium on the Ocean's Role in Climate (CORC) project. It represents a small, quality-controlled scientific program focused on sensor validation.

Use Cases

• Calibrating long-term mooring salinity records using discrete water sample data.
• Validating sensor performance for the CORC project's oceanographic instruments.
• Analyzing water column properties from two specific CTD cast locations in the NE Pacific.

Strengths

• Data has been quality-controlled and adjusted using physical water samples, suggesting a high level of accuracy for salinity.
• Cross-platform presence on datagov and NASA Earthdata indicates recognized importance and curation.
• Associated with a specific, documented research expedition (RR1214) and a known NCEI raw data accession (0129852).

Limitations

• Extremely limited spatial and temporal scale, with only two CTD casts and a small number of water samples from a single month.
• Critical metadata such as column names, row counts, file formats, and license are completely absent from all sources.
• Sources conflict on the 'last updated' date, with one showing 2012 and others showing 2026, creating uncertainty about data currency.
