Hydrographic Profile Data from SEWARD JOHNSON Cruise SJ0609

Hydrographic profile data containing chemical, physical, and optical measurements from cruise SJ0609 in the tropical North Atlantic and Caribbean Sea. The dataset was collected by the National Oceanic and Atmospheric Administration aboard the SEWARD JOHNSON, covering 22 hydrographic stations across three cruise legs from June 22 to July 24, 2006. It is hosted on multiple government data platforms, indicating its established use.

Use Cases

• Analyzing vertical water column profiles for chemical and physical properties at 22 distinct stations.
• Studying temporal and spatial variability of oceanographic conditions during a summer 2006 cruise.
• Investigating repeated sampling events at specific stations, identifiable by sequence numbers (e.g., 022.01, 022.03).
• Mapping the cruise track and data coverage from Florida to Barbados to Cape Verde and the equator.

Strengths

• Data covers a specific, well-documented research cruise with three legs and 22 hydrographic stations.
• Includes repeated casts at single stations, allowing for analysis of temporal variability at fixed locations.
• Dataset is maintained on multiple authoritative platforms (Data.gov and NASA Earthdata), supporting reliability and access.

Limitations

• Specific column names, row counts, and file sizes are not provided by any source, limiting detailed assessment.
• Conflicting last update dates exist between platforms (2006-07-24 on NASA vs. 2026 03-05 on Data.gov), creating uncertainty about metadata freshness.
