WHOI ITP #4: Arctic Ocean Temperature and Salinity Profiles, 2006-2007

WHOI Ice Tethered Profiler #4 collected 698 profiles of ocean salinity and temperature over 349 days. Deployed on September 3, 2006, it was the first ITP configured for a standard schedule of two daily profiles between 7 and 760 meters depth. The instrument, operated by SCIOPS, transmitted daily status data and was recovered for direct data retrieval.

Use Cases

• Analyzing vertical temperature structure in the Arctic Ocean based on daily profile data
• Studying salinity gradients and freshwater content from the 7-760 meter depth profiles
• Modeling seasonal changes in ocean properties over the 349-day deployment period
• Calibrating satellite or model-derived ocean data with in-situ temperature and salinity measurements

Strengths

• Contains 698 individual profiles, providing high temporal resolution for the deployment period
• Operated on a standardized schedule of two profiles per day, ensuring consistent sampling
• Collected data over a 349-day period, capturing seasonal variability

Limitations

• Last updated 2007-08-18 23:59:59.999000; freshness should be verified
• Column-level documentation is absent; field semantics must be inferred after download
• Row count is unknown, which may limit suitability assessment
