Sonobuoy deployment log of the 2013 Antarctic Blue Whale Voyage to the Southern Ocean

The sonobuoy deployment log is a csv file that contains metadata on the deployment of sonobuoys deployed during the 2013 Antarctic Blue Whale Voyage. The first row contains column headers, while each subsequent row contains deployment information for a single sonobuoy.

Data that were recorded during each sonobuoy deployment are:

buoyID: Buoy ID number is the sequential number of the buoy starting at 1 for the first buoy of the trip.

startDate: Date (UTC) at the start of the sonobuoy deployment (YYYY-MM-DD)

startTime: Time (UTC) at the start of the sonobuoy deployment (HH:MM:SS) 2 digit hour with 24 hour clock and leading zero.

stopDate: Date (UTC) at the end of the sonobuoy deployment (YYYY-MM-DD). While the recording is in progress this should be 1,2 4 or 8 hours after the startTime based on sonobuoy setting.

stopTime: Time (UTC) at the end of the sonobuoy deployment (HH:MM:SS). While the recording is in progress this should be 1,2 4 or 8 hours after the startTime based on the sonobuoy setting.

lat: Latitude of deployment in decimal degrees. Southern hemisphere latitudes should be negative.

long: Longitude of deployment in decimal degrees. Western hemisphere longitudes should be negative.

alt: Depth of the sonobuoy deployment in metres. For DIFAR sonobuoys either 30, 120 or 300.

recordingChannel: This is the channel number within the recorded wav-file that contains audio from this buoy as would be reported by Matlab. Channel numbers start at 1 (1-indexed) so usually this will be 1, 2 or 3.

magVariation: The magnetic variation in degrees. Positive declination is East, negative is West. At the start of a recording this will be entered from a chart. As the recording progresses, this should be updated by measuring the bearing to the vessel.

sonobuoyType: The an/ssq designation for the sonobuoy. Usually 53B, 53D, 53F, HIDAR, 57A/B, or 36Q.

receiver: The type and serial number of the calibrated radio receiver (WinRadio) used to receive the VHF signal. (wr15725, wr17274, wr15274, or wr15273)

preamp: The (unitless) gain in dB of any preamplifier (including the instrument preamp from the Fireface UFX). Usually 10 or 20 dB.

adc: The analog-to-digital converter (adc) used to digitize the audio. This is the sound card name and gain. All data were recorded on an RME Fireface UFX, so Ufx10 would be the RME Fireface UFX with a gain of 10 dB.

vhfFreq: The VHF channel number used to receive the sonobuoys. Sonobuoys have 99 pre-set VHF channels between

Purpose: This dataset contains the location, time, and details of sonobuoys deployed during the 2013 Antarctic Blue Whale Voyage. It also contains information about the acoustic recording chain that are essential for obtaining calibrated sound level measurements and calibrated acoustic bearings to the sound source.
