Barometric Pressure and CTD Data from 1992 Arctic Ocean Cruises

CTD and barometric pressure data were collected during three research cruises (HX 163, HX 165, HX 167) of the ship ALPHA HELIX. The dataset covers the Gulf of Alaska, Chukchi Sea, and the northwest Pacific Ocean from July 24 to October 27, 1992. Data was submitted by Dr. Thomas C. Royer of the University of Alaska's Institute of Marine Science.

Use Cases

• Analyze vertical profiles of conductivity, temperature, and depth (CTD) to study water column structure in the Chukchi Sea.
• Correlate barometric pressure readings with oceanographic conditions across the Gulf of Alaska and northwest Pacific.
• Use cruise-track data (HX 163, HX 165, HX 167) to map spatial variations in sea surface properties.
• Investigate temporal changes in ocean parameters from July to October 1992 for seasonal transition studies.

Strengths

• Data collected over a 3-month period from July to October 1992.
• Covers three distinct oceanographic regions: Gulf of Alaska, Chukchi Sea, and NW Pacific.

Limitations

• Data is over 30 years old, limiting its use for contemporary climate analysis.
• Specific row count, column details, and file formats are unknown.
• Geographic coverage is limited to specific cruise tracks, not a continuous survey.
