Teilprojekt 2: Akustik

Description: Das Projekt "Teilprojekt 2: Akustik" wird vom Umweltbundesamt gefördert und von Stiftung Alfred-Wegener-Institut für Polar- und Meeresforschung e.V. in der Helmholtz-Gemeinschaft (AWI) durchgeführt. Diel vertical migration and geographical distribution of our target organism krill (Euphausia superba, E. crystallorophias) but also other species e.g. myctophids, copepods (Calanus propinquus, Rhincalanus gigas), and other zooplankter (salps, pteropods, chaetognaths, amphipods) are detected by means of a four-split beam acoustic array (38, 72, 120, 200 kHz). Our major questions are: Do organisms migrate daily in relation to the light field, feeding conditions and/or to the predator field? Do populations of different species and/or different developmental stages of one species segregate in certain environmental conditions or different times of the year? How does the ocean current system influence the geographical distribution of zooplankton or krill populations? Is the geographical distribution of species subject to change and if so, what are the possible causes?
