Mid-Atlantic Bight Water Chemistry CTD Profiles 2017

Water temperature, salinity, oxygen, dissolved inorganic carbon, pH, and methane data were collected from 293 discrete water samples during a 2017 research cruise. Measurements were taken using CTD casts and Niskin bottles along five transects in the Mid-Atlantic Bight, from near-surface to near-seafloor depths. The dataset was produced by the National Oceanic and Atmospheric Administration.

Use Cases

• Analyzing dissolved inorganic carbon (DIC) and pH to study ocean acidification dynamics.
• Correlating water temperature, salinity, and oxygen profiles to identify distinct water masses.
• Mapping methane concentration anomalies across the shelf break transects.
• Investigating the relationship between natural radiocarbon in DIC and water column processes.
• Modeling the vertical distribution of chemical parameters from surface to near-seafloor depths.

Strengths

• Contains 293 discrete water samples from a systematic grid of 25 stations.
• Includes multiple chemical parameters (DIC, pH, methane, radiocarbon) measured from the same Niskin bottles.
• Samples cover a depth range from approximately 2 meters to within 5 meters of the seafloor.

Limitations

• Exact column names and data structure are not provided by any source.
• Sources conflict on the 'last updated' date, with one listing 2026-03 05 and another 2017-09-03.
• License information is not specified.
