PACIFICA P02W: CTD and Bottle Oceanographic Profiles from the North Pacific, 1994

From November 1 to 14, 1994, the R/V SHOYO collected discrete sample and profile data in the North Pacific Ocean and Philippine Sea during cruise PACIFICA_492S19941101, which was also part of the World Ocean Circulation Experiment (WOCE) P02W line. The dataset includes measurements of dissolved oxygen, hydrostatic pressure, potential temperature (theta), salinity, and water temperature, gathered using CTD and bottle instruments. This data was synthesized as part of the international PACIFICA project, focused on ocean interior carbon and related parameters in the Pacific Ocean.

Use Cases

• Analyzing vertical ocean structure based on CTD profiles of temperature, salinity, and pressure.
• Studying dissolved oxygen distribution for biogeochemical and climate models.
• Calibrating satellite-derived sea surface salinity with in-situ bottle sample data.
• Investigating water mass formation and circulation along the WOCE P02W transect.

Strengths

• Data is associated with a major international oceanographic program (WOCE) and a collaborative carbon synthesis project (PACIFICA).
• Provides a focused, two-week temporal snapshot from a specific research cruise, allowing for detailed process studies.
• Includes complementary data types from two instrument sources (CTD profiles and discrete bottle samples).

Limitations

• Critical metadata is missing: row count, file size, column names, and specific license are not provided by any source.
• There is a conflict in the reported 'last updated' date between platforms (2026-03-05 vs. 1994-11-14), casting doubt on maintenance.
• The dataset's scope is limited to a single, short cruise, restricting broad spatial or temporal analysis.
