Description
High-resolution conductivity-temperature-depth (CTD) and salinity-temperature-depth (STD) cast profiles were collected in the Pacific Ocean from January 30 to February 14, 1974. The dataset, part of the International Decade of Ocean Exploration North Pacific Experiment (IDOE/NORPAX), contains nearly continuous vertical profiles of temperature, salinity, and computed density (sigma-t). Data were processed by the National Oceanographic Data Center (NODC) into the standard F022 format and may include station metadata, environmental conditions, and parameters like dissolved oxygen.
Use Cases
Analyzing vertical ocean structure based on high-resolution temperature and salinity profiles.
Studying historical water mass properties in the Pacific Ocean during the NORPAX experiment.
Calibrating or validating ocean models using in-situ CTD data from a defined time period.
Investigating short-term oceanographic variability from continuous profile data reported at fine depth intervals.
Strengths
Data has a precisely defined collection period from January 30 to February 14, 1974.
Profiles are high-resolution, with data potentially reported at depth intervals as fine as 1 meter.
Data is structured according to a documented NODC standard format (F022), which includes station metadata and environmental conditions.
Limitations
Key metadata such as row count, column names, file size, and license are unknown across all sources.
Sources conflict on the 'last updated' date, with one listing 2026-03-05 and another 1974-02-14, creating uncertainty about metadata maintenance.
The specific platforms used besides FLIP are not detailed, and the exact spatial coordinates within the Pacific Ocean are not provided.
