Wideband acoustic transceiver data from probe attached to rosette on PolarFront 2022-05 cruise

<p><strong>PolarFront 2022-05&nbsp;WBAT/Rosette</strong></p> <p>Proprietary echosounder files and mission plan from Kongsberg Maritime WBT tranceiver EKA, serial number 253119.</p> <p>Time coverage: 2022-05-20T04:32:12Z/2022-05-25-T12:30:06Z</p> <p>Size: 2.8GiB</p> <blockquote> <p><strong>Acoustic probe (WBAT)</strong><br> At some stations&nbsp;we deployed an acoustic probe composed of a Wideband Acoustic<br> Transceiver (WBAT; Kongsberg Maritime AS) mounted on the LOPC rosette frame and connected to<br> a sideward-looking 38 kHz split beam transducer (Model ES38-18DK; 36-45 kHz) and a sideward-<br> looking 333 kHz single beam transducer (Model ES333-7CDK-single; 280-380 kHz), both operated in<br> broadband mode split-beam wideband (Figure 1c). The ping rate was set to 1 second, the range to 50<br> m, the pulse length to 2,048 &micro;s, and power to 225 W at 38kHz and 38 W at 333 kHz. The WBAT was<br> calibrated in January 2022. The time of the WBAT was synchronized with the LOPC-CTD to extract<br> the exact depth at each ping.</p> </blockquote> <p>For a list of probe stations, see M Daase (ed., 2022, table 4.1, p. 32).</p> <p><strong>References</strong></p> <p>Malin Daase (ed.)
