Water temperature measurements were collected under an ice floe in the Arctic Ocean during the Second Chinese Arctic Research Expedition. Data originates from 8 measuring units arranged in a line with specific intervals, each containing 8 probes at depths from 0 to 20 meters, recorded at 1-minute intervals. The data was collected by the SCIOPS organization from August 25 to September 4, 2003, and has undergone quality control.
Use Cases
- Analyzing temporal variation in water temperature at specific depths (0m, 0.5m, 1m, 1.5m, 2m, 5m, 15m, 20m) under sea ice.
- Modeling vertical temperature gradients and thermal structure in the upper ocean adjacent to an ice floe.
- Investigating spatial temperature differences using data from units placed at intervals of 20m, 50m, 100m, 150m, 200m, and 250m from a central point.
- Studying near-edge ice-ocean interactions by comparing data from units 5m and 150m from the floe edge.
Strengths
- High temporal resolution with measurements recorded every 1 minute.
- Detailed vertical profiling with 8 probes per unit covering depths from 0 to 20 meters.
- Explicit spatial arrangement of 8 units along a transect with defined intervals.
- Data has undergone stated quality control procedures.
Limitations
- Very limited temporal coverage, spanning only 11 days in 2003.
- Spatial coverage is restricted to a single ice floe (CNIS7) and transect line.
- Unknown sample size and data volume as row count and file size are not provided.
