Description
Puget Sound oceanographic data from January to February 1973, collected via CTD and STD casts from the NOAA Ship McARTHUR. The dataset provides high-resolution vertical profiles of temperature, salinity, density, and potentially dissolved oxygen or transmissivity. Data were processed to the NODC standard F022 format, which may include cruise metadata, station positions, and environmental conditions.
Use Cases
Analyzing vertical stratification of temperature and salinity in Puget Sound based on high-resolution profile data.
Studying seasonal water property variations in early 1973 using the time-series of station casts.
Calibrating regional oceanographic models with historical conductivity-temperature-depth measurements.
Investigating relationships between computed density (sigma-t) and other measured parameters.
Strengths
Data is in a standardized, high-resolution format (NODC F022) with depth intervals as fine as 1 meter.
Provides a focused temporal snapshot of Puget Sound water properties over a defined period in 1973.
Dataset is hosted on multiple authoritative platforms (NASA Earthdata, Data.gov), indicating vetting and persistence.
Limitations
Source platforms conflict on the exact collection end date (February 12 vs. February 14, 1973).
Critical metadata is missing, including specific column names, row count, file size, and license information.
Data is historical (from 1973) and the last update field appears to be a system artifact, not a content refresh.

The 'last updated' metadata on some platforms is in the future (2026), which is likely a system error and does not reflect actual data currency.
