Description
423 days of oceanographic observations from a mooring deployed in the Beaufort Gyre from 2008 to 2009. The dataset includes 40,604 samples of pressure, temperature, and salinity from a bottom recorder and 377 profiles of pressure, temperature, salinity, and horizontal velocity from a moored profiler. Data was collected by the SCIOPS organization as part of the Beaufort Gyre Exploration Project.
Use Cases
Analyze temporal trends in bottom pressure, temperature, and salinity from 40,604 samples to study seasonal water mass changes.
Use 377 profiles of horizontal velocity and salinity to calculate geostrophic currents and freshwater transport in the Beaufort Gyre.
Correlate temperature and salinity profiles from the moored profiler to identify layers of Arctic water masses.
Combine pressure recorder time-series with profiler data to assess the vertical structure and stability of the water column over the deployment period.
Strengths
423-day continuous deployment provides a full annual cycle of observations.
40,604 high-frequency samples from the bottom pressure recorder offer detailed temporal resolution.
377 vertical profiles from the moored profiler capture the water column's physical properties.
Limitations
Sample size for profiler data (377 profiles) is limited compared to the bottom recorder's 40,604 samples.
Data from the upward-looking sonar is noted as still being processed and is unavailable.
The dataset's temporal coverage is limited to a single year, restricting long-term trend analysis.
Provenance
Source
Beaufort Gyre Exploration Project, SCIOPS organization, via NASA Earthdata.
Collection Method
In-situ measurements from a moored oceanographic platform equipped with a bottom pressure recorder, a McLane Moored Profiler, and an upward-looking sonar.
Time Range
2008-2009 (423-day deployment).
Freshness
Data collection ended in 2009; the dataset is not updated.
Geography
Beaufort Gyre region of the Arctic Ocean (specific mooring location D).
Upward-looking sonar data is noted as still being processed and is not included in the described dataset. The specific file formats and data access methods are not provided in the input.
