How to interpret this dataset

Query options

• frequency: Millidecade band (centre frequency)
• Timeframe: Starting and stopping date for the query.

Available columns

• frequency: Centre frequency of the millidecade band, in Hz
• upper_frequency: Upper frequency limit of the millidecade band, in Hz
• lower_frequency: Lower frequency limit of the millidecade band, in Hz
• value: Sound pressure density of the millidecade band
• datetime: ISO 8601 Date and Time in UTC, beginning of sample time bin
• Latitude: Center latitude in decimal degrees, WGS84.
• Longitude: Center longitude in decimal degrees, WGS84.
• station_name: Name or code of sampling station.
• hydrophone_depth: Depth in the water column, in (positive) meters
• etnID: Unique identifier for each deployment, linked to the metadata specified in the European Tracking Network (https://www.lifewatch.be/etn/)
