2. Long-term forecast of the conditions of krill (Euphausia superba Dana) fisheries in the Antarctic part of the Atlantic Ocean

   . Mechanism of links can be explained as follows. It was stated that anomaly of the solar activity index is ... inversely linked with recurrence of zonal atmospheric transfers. The latter is directly associated with the ... index of krill abundance in the first of the abovementioned areas and inversely linked with one in the ...

3. Performance of an acoustic sonde design

   macrozooplankton and micronekton. It was concluded that in order to survey animals in the size range 0.5-5 cm, it ... would be expedient to use at least three and perhaps as many as 8-10 frequencies in the range 38-420 kHz ... frequencies are chosen. Each frequency represents the resonant condition of a circular piston transducer with ... single targets, assuming transmission near the cavitation limit but consistent with dynamic strength and ...

5. An alternative method for estimating the level of illegal fishing using simulated scaling methods on detected effort

   uncertainty increases as the evasion rate increases. This research suggests that it would be possible to ...
