Coastal Ocean CTD Data from Gulf of Maine Aquaculture Project

CTD (conductivity, temperature, depth) data collected for the Open Ocean Aquaculture Demonstration Project in coastal New Hampshire waters near the Isles of Shoals. Measurements include pressure, temperature, salinity, and dissolved oxygen, gathered from the R/V Gulf Challenger between March and May 1999. The dataset was released by the University of New Hampshire and is hosted by NOAA NCEI.

Use Cases

• Analyzing water column stratification using temperature and salinity profiles.
• Assessing dissolved oxygen levels for aquaculture site suitability studies.
• Calibrating regional oceanographic models with in-situ pressure and temperature data.
• Monitoring seasonal changes in coastal hydrography during spring.

Strengths

• Data originates from a specific research project (Open Ocean Aquaculture Demonstration) with a clear purpose.
• Measurements were taken using a standardized SeaBird SBE29 CTD system, ensuring instrument consistency.
• The dataset has a precisely defined collection period from March 20 to May 21, 1999.

Limitations

• Column names and the exact row count are not provided by any source, limiting detailed analysis.
• Sources conflict on the last updated date: one platform shows 2026-03-05 (likely a metadata refresh), while another shows 1999-05-21 (the collection end date).
