Hydrographic Data from the Gulf of California, April-May 2013

From April 19 to May 2, 2013, hydrographic data were collected in the Pescadero Basin and along the West Coast of Baja and California aboard the R/V Point Sur. The dataset, provided by NOAA NCEI, includes profiles of conductivity, temperature, dissolved oxygen, nutrients, and ocean currents from fixed stations, as well as underway observations of sea surface and atmospheric properties. The collection aimed to measure water exchange between the Pacific Ocean and Gulf of California and study the California Undercurrent.

Use Cases

• Modeling water exchange between the Pacific Ocean and Gulf of California based on hydrographic profiles.
• Analyzing the flow patterns of the California Undercurrent based on ocean current observations.
• Studying variations in water properties like temperature and salinity along the 1000 m isobath.
• Investigating anticyclonic flow patterns in the Pescadero Basin based on the reported observations.

Strengths

• Data collection includes multiple variables: conductivity, temperature, dissolved oxygen, nutrients, and ocean currents.
• Observations were made from both fixed stations and underway, providing spatial context.
• The temporal coverage is precisely defined from 2013-04-19 to 2013-05-02.

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
