WHOI Ice Tethered Profiler #7: Arctic Ocean Temperature and Salinity Profiles

746 profiles of temperature, salinity, and pressure collected over 186 days by an Ice Tethered Profiler (ITP). The instrument operated on a fast sampling schedule of 4 one-way profiles between 7 and 760 meters depth each day. It was deployed on a 2.5 m thick ice floe in the Transpolar Drift as part of the North Pole Environmental Observatory (NPEO).

Use Cases

• Modeling Arctic Ocean water column structure based on temperature and salinity profiles.
• Analyzing daily and seasonal variability in the upper ocean based on the 4-profile-per-day sampling schedule.
• Studying the physical properties of the Transpolar Drift region based on the deployment location.
• Calibrating remote sensing or other observational data with in-situ profile measurements.

Strengths

• 746 individual profiles provide a substantial time-series record.
• Data collection occurred over a continuous 186-day period.
• Profiles cover a defined depth range from 7 to 760 meters.
• Instrument was deployed on a specific, thick (2.5 m) ice floe in a known region.

Limitations

• Last updated 2008-02-08 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.
