Bioacoustics

    At the German Oceanographic Museum acoustic monitoring of echolocation clicks is used to gather more information on the distribution of Baltic harbour porpoises. Large monitoring areas and long term data acquisition allow for determining the seasonal distribution of porpoises in the German Baltic Sea using presence/absence data. To determine the abundance, however, additional information is critically needed. For instance detection functions of the used data loggers (C-PODs) are determined to allow for calculating the monitored area.

Different data loggers are available nowadays. They all vary with regard to handling, performance and technical details.  Comprehensive testing is needed to determine acoustic properties of these devices. This is necessary to be able to choose the adequate logger for future Monitoring schemes, as well as to ensure comparability of data which was collected with different loggers.

Stabile Isotopes

    With the help of this relative young method (Fry 1980) it is possible to determine, among other things, food chains, food preferences and migration patterns. Carbon, nitrogen and sulfur are the three main elements, whose stable isotopes show patterns in the marine ecosystem. However these patterns can be masked by different factors. The combination of the results of the isotopic analysis with other methods such as stomach content analysis, acoustic and visual detections or behavioral observations can be used to analyse the underlying patterns.
