Description
February 14 to March 21, 1965, this dataset contains mechanical bathythermograph (MBT) observations from the NORWALK cruise in the North Atlantic Ocean. It provides temperature-depth profile pairs recorded at uniform 5-meter intervals, processed by the National Oceanographic Data Center (NODC) into its standard C128 format. The data is published by the National Oceanic and Atmospheric Administration.
Use Cases
Analyzing the vertical temperature structure of the upper 285 meters of the ocean during a specific 1965 cruise.
Studying temporal changes in sea surface temperature and near-surface thermal gradients over the five-week observation period.
Validating or providing historical context for models of upper ocean heat content and mixed layer dynamics.
Correlating cruise-reported position and time data with temperature observations for spatial analysis of thermal features.
Strengths
Data is processed to a documented standard format (NODC C128), ensuring a consistent structure for analysis.
Provides a focused temporal snapshot with a clear time range from 1965-02-14 to 1965-03-21.
Temperature measurements are recorded at a consistent, high-resolution vertical interval of 5 meters.
Cross-platform presence on government data portals indicates formal curation and archival importance.
Limitations
The dataset is limited to the upper ocean, with a maximum instrument depth of approximately 285 meters.
Key metadata such as exact row count, file size, and specific column names are not provided in the available descriptions.
The dataset is historical, with the last observation date in 1965, limiting analysis to past conditions.
