CalCOFI Line 67 Hydrographic Profiles from March 2012 PaCOOS Cruise

Hydrographic data from the California Current system were collected during a Pacific Coast Ocean Observing System (PaCOOS) cruise aboard the R/V Point Sur from March 27-30, 2012. The cruise sampled along CalCOFI line 67 from Moss Landing, California, to station 90, performing 19 standard CTD casts and inserting 8 additional casts for higher resolution. Data collection involved multiple institutions including the Naval Postgraduate School, Monterey Bay Aquarium Research Institute, UC Santa Cruz, and Moss Landing Marine Laboratories.

Use Cases

• Analyzing vertical profiles of temperature and salinity (CTD data) for water mass characterization.
• Studying nutrient concentrations and their spatial distribution along a coastal transect.
• Investigating primary productivity and zooplankton dynamics in relation to physical oceanographic conditions.
• Calibrating and validating regional oceanographic models for the California Current system.

Strengths

• Data collection follows the established CalCOFI grid and methodology, ensuring comparability with a long-term time series.
• High spatial resolution was achieved with 27 CTD casts along a single transect, exceeding the standard CalCOFI station sampling.
• Analysis was conducted by multiple specialized research institutions (Naval Postgraduate School, MBARI, UCSC, MLML).

Limitations

• Specific column names, row counts, and dataset size are not provided by any source, limiting detailed assessment of structure and volume.
• Sources conflict on the 'last updated' date, with one listing 2012-03-30 and others listing 2026-03-05, creating uncertainty about metadata maintenance.
