The central Arctic Ocean was the focus of the interdisciplinary ASCOS expedition aboard the icebreaker Oden from August 1 to September 9, 2008. This dataset provides mean temperatures, salinities, horizontal current velocities, and turbulent fluxes of heat and salt in the upper ocean mixed layer. The data was collected by the SCIOPS organization using a turbulence instrument cluster deployed through the ice.
Use Cases
- Analyzing turbulent heat flux and salt flux to quantify energy transfer between the ocean and sea ice.
- Modeling upper ocean mixed layer dynamics using concurrent measurements of temperature, salinity, and horizontal current velocities.
- Studying the relationship between ocean turbulence and atmospheric conditions during the Arctic summer melt season.
Strengths
- Data originates from a dedicated, interdisciplinary Arctic expedition with precise temporal bounds.
- Includes directly measured turbulent fluxes, which are rare for the central Arctic region.
Limitations
- The dataset is limited to a single location and a short time period of approximately 40 days.
- Sample size and specific row/column counts are unknown, limiting statistical assessment.
