<div><p>One mooring was deployed to the eastern (AMLR2) and western (AMLR1) sides of Palmer Deep Canyon to 400 and 345 m, respectively. AMLR1 was deployed at -64.2119, -64.8124 (longitude/latitude) and AMLR2 was deployed at -64.0376, -64.864.</p>
<p>Both moorings were deployed on 6 January 2020. The western mooring was recovered on 3 February and the eastern mooring was recovered on 7 March 2020. The upward facing echosounders pinged at 6 s intervals and had 1168 vertical bins representing 0.375 m in range. These datasets include the 120 kHz returns.</p></div>
SWARM AMLR moorings - acoustic data
<div><p>Each mooring has three data files associated with it:<br />
1) an "_Sv" file containing the processed acoustic return from the mooring in volume backscattering strength in decibels (dB) from the 120 kHz narrowband echosounder in a matrix where rows represent single pings and columns indicate depth bins;<br />
2) a "_dp" file representing the depth (in meters) of the depth bins for each return with the same dimensions as the "_Sv" file; and<br />
3) a "_tm" file containing a vector of timestamps corresponding to each ping in seconds since Jan 1 1970 (POSIX), where the length of the vector is equivalent to the number of rows in each matrix.</p>
<p>These files are all available in the attached "all_moorings_files.tar.gz" file.</p></div>
SWARM AMLR moorings - acoustic data
<div><p><strong>Data Processing:</strong><br />
Raw data were processed using the methods outlined in Cutter et al., 2022. Individual .mat files that resulted from processing procedures were concatenated in R by row using rbind to produce single acoustic return (Sv), time, and depth files for each mooring. Time was transformed from Julian day to POSIX time in R. Data processing methods can be found in Cutter, et al. (2022).</p>
<p><strong>BCO-DMO Processing:</strong><br />
- saved the csv files in a single .tar.gz file</p></div>
