This project aims to integrate nature conservation into maritime spatial planning. In order fully understand the spatial claims of all three marine mammal species inhabiting German waters, a method of assessment will be developed.(more information)

In this project the findings regarding grey seal predation, which were obtained in an earlier pilot study, shall be applied and extended. (more information)

Habitat models (e.g. GAMs) were created for whale species which react sensitively to underwater noise, based on compiled sighting and environmental data. (more information)

Little is known about the influence of anthropogenic stressors on the health status of marine mammals. (more information)

It was hypothesized that the hydrodynamic design of a tag could
provide stable attachment to the dorsal fin of dolphins. (more info) 

This project aims to develop models for the minimization of sound radiation under water. (more info)

In order to assess and monitor the positive status of Baltic marine mammals, indicators for the determination of the good environmental status (GES) shall be developed further in the framework of HELCOM. (more information)

Rescued harbor seals were examined to determine health status, emphasizing acquisition of zoonosis and infectious agent data. (Further information)

The Doggerbank, the largest sandbank of the central North Sea, is an important habitat of the minke whale (Balaenoptera acutorostrata), which is the most frequently occurring baleen whale species in the entire North Sea.(more information)

Investigations of the acoustic organs of Baltic harbour porpoises shall be conducted during this study and be included in a health assessment of these animals.(more information)

The permanent changes in the immediate environment of mammals by so-called “environmental stress” have become an important part in veterinary research.(more information)

Study of the potential drag-reducing properties of dolphin skin (more information) 

The general objective of MINOS plus was to gain basic knowledge with regard to possible impacts that the construction of offshore windmill-parks could have on the marine environment. (more information)

Aim of the project is monitoring and status assessments of marine vertebrates.. (more information)

In this project aerial and ship surveys are conducted to estimate the German harbour porpoise population size and to investigate the relationship between occurrence of pelagic fish and porpoises. (more info)

In this pilot study the newly recognised predation behaviour of grey seals will be examined and evaluated. (more information)

The ITAW assumes the acoustic examination of harbour porpoises in the context of a conjoint marine mammal monitoring during this project (more information).

(more information)

Cetaceans are found regularly near South African coasts and are bycaught in anti shark nets in KwaZulu-Natal frequently. The aim of the project is to develop a necropsy protocol in order to record and document the animals´ health status. (more information)

The anatomy and pathology of ears of harbour porpoises (Phocoena phocoena) coming from German and Danish waters of the North and Baltic Seas are being comprehensively investigated in this study (more information)

The aim of this subproject within the DEPONS project (Disturbance Effects on the Harbour Porpoise Population in the North Sea; www.depons.au.dk), was to identify areas in the North Sea with high porpoise densities (more information)

Wild animal welfare, their diseases and zoonotic potential have become an increasingly important issue among wildlife populations, health investigators and authorities of the German coastal environment. (more information)

Harbour porpoises (Phocoena phocoena) occupy a top position in the marine food web. Therefore, they accumulate high levels of harmful chemicals such as organochlorides or heavy metals. (more info)

The SCANS projects aim to acquire the abundance and distribution of small cetaceans in the North Sea and adjacent waters coordinately in regular intervals.  (more information)

The grey seal population and its distribution in the Lower Saxonian Wadden Sea was registered during the breeding season (more info)

The project aims to count the grey seals and harbour seals occurring in the whole wadden sea of Lower Saxony and Hamburg in spring (April).   (more info)

Morbillivirus infections are found consistently in marine mammals.(more info) 

Construction of offshore wind turbine generators (WTGs) in the German North and Baltic Seas is accompanied by extensive noise input to the marine environment.In the aim of this project  a threshold value for the auditory tolerance of harbour porpoise should be astablished.(further information)

In this project harbour porpoises were to be recorded visually during the noise intensive construction phase of the future offshore wind farm "Butendiek". (more information)
