Temporal distributions of Antarctic krill ( Euphausia superba ) density and aggregation types were characterized and compared using Nortek Signature100 and SIMRAD Wideband Autonomous Transceiver (WBAT) upward-looking echosounders. Noise varied between the two echosounders. With the ...

The Danube Canyon, the largest submarine valley in the Black Sea, was discovered much later, in 1950, during an echo sounder cruise (Dimitrov and Solakov, 2002). It was initially named Vityaz Danube Canyon The Danube Canyon is located 100 km southeast of the Danube Delta (Fig. 8). ...
Studies using Ku-band CryoSat-2 have shown promise in distinguishing FYI and MYI based on the parametrisation of the radar echo. Here, we investigate applying the same classification algorithms that have shown success for Ku-band measurements to measurements acquired by SARAL/AltiKa at the Ka-...

Thus, to estimate the community structure of various algae assemblages, we developed a classification method using a combination of acoustic-derived physical distance and backscattering strength parameters using a scientific echosounder. The prediction accuracy for algae or barren seafloor using four ...
