1569 ocean profiles were collected from August 2007 to October 2009 by an Ice Tethered Profiler operated by SCIOPS. The instrument performed two daily profiles between 7 and 760 meters depth, recording temperature and location data while drifting with the Beaufort Gyre. Data transmission was reliable for the first 707 profiles, with additional data recovered upon instrument retrieval.
Use Cases
- Analyzing vertical temperature structure in the Arctic Ocean based on daily profiles to 760m depth.
- Tracking the drift path and movement of sea ice based on hourly GPS location data.
- Studying water column characteristics along the Beaufort Sea slope and Chukchi shelf region based on the described drift path.
- Investigating instrument performance and data recovery in remote, ice-covered environments based on the described modem failure and subsequent data retrieval.
Strengths
- 1569 profiles collected over a two-year period from 2007 to 2009.
- Standardized sampling schedule of two daily profiles between 7 and 760 meters depth.
- Hourly GPS location recordings provide detailed drift trajectory.
- Data recovered from 862 additional profiles upon instrument retrieval.
Limitations
- Last updated 2009-03-10 23:59:59.999000; freshness should be verified.
- Column-level documentation is absent; field semantics must be inferred after download.
- An inductive modem failure prevented real-time transmission of full data for part of the deployment.
