Gulf of Maine Water Column Carbonate Chemistry Profiles, 2013-2015

From May 2013 to July 2015, eleven short cruises on the R/V Tioga collected discrete profile measurements of dissolved inorganic carbon, total alkalinity, dissolved oxygen, temperature, and salinity. The data were gathered at a series of six stations in Wilkinson Basin, with a focus on capturing seasonal variation and studying the spring-summer transition. This dataset was produced by the National Oceanic and Atmospheric Administration, Department of Commerce.

Use Cases

• Modeling seasonal variation in carbonate chemistry based on repeated station sampling.
• Analyzing water column stratification based on profile measurements of temperature and salinity.
• Studying coastal ocean acidification dynamics based on dissolved inorganic carbon and total alkalinity data.
• Comparing deep-basin and shallow-flank station chemistry based on the described station network.

Strengths

• Data collection spanned over two years from 2013 to 2015, capturing seasonal cycles.
• Sampling focused on a specific deep-basin station (Station 2, depth >250m) that was occupied during every cruise.
• The dataset includes five core oceanographic parameters: DIC, total alkalinity, oxygen, temperature, and salinity.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for large-scale modeling.
• Data may reflect geographic bias inherent to the Wilkinson Basin study area.
