Arctic Ocean CTD Station Data from 1995 Cruise

209 Conductivity, Temperature, and Depth (CTD) station profiles were collected in the Chukchi Sea during the HX-190 cruise of the R/V Alpha Helix. The Institute of Marine Science at the University of Alaska, Fairbanks gathered this data for an Office of Naval Research project between September 11 and October 8, 1995. Data was submitted to the National Oceanographic Data Center in the F022 format.

Use Cases

• Analyze vertical profiles of conductivity, temperature, and depth to characterize water mass structure in the Chukchi Sea.
• Correlate CTD station data with barometric pressure readings to study air-sea interaction processes.
• Map the spatial distribution of 209 CTD casts to identify regional hydrographic gradients.
• Use the time-series from September to October 1995 to examine early autumn changes in Arctic ocean conditions.

Strengths

• Data from 209 distinct CTD stations provides spatial coverage.
• Measurements span a 28-day period in 1995, capturing seasonal transition.

Limitations

• Data is from a single cruise in 1995, limiting temporal generalizability.
• Unknown sample resolution and specific column definitions for CTD profiles.
• No information on data quality control or calibration procedures applied.
