Ocean Dumping Site Characterization with High-Resolution CTD Profiles

Profiles of oceanographic parameters collected during a 1976 NOAA cruise to characterize Dumpsite 106 in the Northwest Atlantic. Data was gathered by the NOAA Ship Oregon II and processed into the NODC's high-resolution F022 format, containing nearly continuous measurements at depth intervals as fine as 1 meter. The dataset includes temperature, salinity, density, and potentially dissolved oxygen or transmissivity readings.

Use Cases

• Analyzing vertical water column structure using temperature, salinity, and density (sigma-t) profiles.
• Investigating potential pollutant dispersion patterns at a designated ocean dumping site.
• Establishing historical baselines for oceanographic conditions in the Northwest Atlantic.
• Correlating subsurface measurements with surface meteorological conditions reported for each station.

Strengths

• Data is in a standardized, high-resolution format (NODC F022) with profiles at intervals as fine as 1 meter.
• Includes precise station metadata such as position, date, time, and sampling interval for each cast.
• Collected by a NOAA research vessel (Oregon II) for a specific environmental characterization mission.

Limitations

• Specific row counts, column names, and file sizes are not provided by any source.
• Sources conflict on the last updated date, with one showing a future date (2026-03-05) and another showing the collection date (1976-02 25).
• The presence of other parameters like dissolved oxygen or transmissivity is noted as 'possibly' included, not guaranteed.
