Woods Hole Oceanographic Institution collected electric field, temperature, and conductivity data from the ATLANTIS II research vessel from November 14 to 21, 1971. Electric field was recorded every half-second, while temperature and conductivity were recorded every second using a freely-falling and rising rotating vehicle in the deep ocean. The data were processed using QDEM and PROFEQ computer programs to derive east and north components of water velocity and create an equally spaced pressure series.
Use Cases
- Analyze temporal patterns in electric field measurements recorded every half-second to study ocean current dynamics.
- Correlate temperature and conductivity data, recorded every second, to characterize water mass properties and salinity.
- Derive east and north components of water velocity from demodulated electric field data for current vector analysis.
- Study the vertical structure of the ocean using the pressure series created by the PROFEQ interpolation program.
- Validate sensor performance and data processing algorithms for freely-falling oceanographic instruments.
Strengths
- High-resolution time-series data with electric field recorded every 0.5 seconds.
- Specific collection period documented from 1971-11-14 to 1971-11-21.
- Data processed with defined computational methods (QDEM for demodulation, PROFEQ for interpolation).
- Vertical filtering applied with a specific 90-decibar triangular filter.
Limitations
- Dataset is over 50 years old, limiting its relevance for studying contemporary ocean conditions.
- Unknown sample size and spatial extent of the data collection.
- Lack of column metadata prevents detailed analysis of individual data fields.
