Abstract Die vertikale und horizontale Verteilung des Planktons im Meer hängt von zahlreichen Faktoren ab und ist in der Regel sehr inhomogen. Die lokale Zusammensetzung variiert zudem mit dem Tagesverlauf. Einige Formen erscheinen nur bei Tag, andere nur bei Nacht. Die meisten Planktonorganismen reagieren sehr empfindlich auf Temperaturschwankungen und Sauerstoffmangel. Die Untersuchung lebender Organismen muß daher zügig erfolgen. Die Untersuchung lebenden Planktons muß sofort nach dem Fang erfolgen, da Temperaturveränderungen, Sauerstoffmangel und erhöhte Lichtintensität schnell zum Absterben vieler Planktonorganismen führen.

The vertical and horizontal distribution of plankton in the sea depends on several parameters resulting in a certain degree of patchiness. The local composition also varies according to the time of the day. Some species emerge only during the day, others only at night. Most of the plankton organisms are very sensitive to changes of temperature and oxygen. Therefore, live organisms have to be studied immediately after sampling. Studies of live plankton should take place immediately after sampling since changes in temperature, oxygen deficiency and increased light intensity cause a rapid mortality of sensitive plankton organisms.
