Abstract

This dataset presents fisheries acoustic data in international HAC format recorded onboard R/V Thalassa on 28/04/2013 between 14:56 and 15:16 GMT near the continental shelf edge in Southern Bay of Biscay. Data include typical small pelagic fish schools composed of anchovy and sardine encountered in springtime in this area. HAC files can be displayed and processed using e.g. the MOVIES3D freeware provided by Ifremer at: http://flotte.ifremer.fr/fleet/Presentation-of-the-fleet/Logiciels-embarques/MOVIES

Sensor metadata

Data were collected during the PELGAS2013 survey using: i) a Simrad EK60 echosounder equiped with 6 vertically oriented transducers operating at the 18, 38, 70, 120, 200 and 333 kHz frequencies, ii) a Simrad EK60 echosounder equiped with 1 horizontally oriented transducer (to starboard side) operating at the 120 kHz frequency, and iii) a Simrad ME70 multibeam echosounder. Echosounders were pinging every 0.6 s operated using a 1 ms pulse length. Other operating parameters can be obtained by selecting a channel and clicking on "View sounder parameter" in the "Affichage" menu of the MOVIES3D software. Minimum recording threshols was set at -100 dB.
