Autor: H. Herr, L. Hickmott, S. Viquerat, S. Panigada

Publikováno v: Royal Society Open Science, Vol 9, Iss 9 (2022)

This study presents the first long-distance tracks of fin whales (Balaenoptera physalus) equipped with satellite transmitters off the Antarctic Peninsula. Southern Hemisphere fin whales were severely depleted by twentieth century industrial whaling,

Opportunistically collected data from aerial surveys reveal spatio-temporal distribution patterns of marine debris in German waters

Autor: Anita Gilles, Patricia Burkhardt-Holm, S. Viquerat, Bianca Unger, Helena Herr, Ursula Siebert

Publikováno v: Environmental Science and Pollution Research International

Marine debris is known for its ubiquitousness and harmful effects on marine life. This study is the first analysis to provide information on the distribution of floating marine debris in German waters using aerial survey data collected between 2002 a

Mid-summer abundance estimates of fin whales Balaenoptera physalus around the South Orkney Islands and Elephant Island

Autor: Helena Herr, S. Viquerat

Publikováno v: Endangered Species Research, Vol 32, Pp 515-524 (2017)

A line-transect distance sampling survey for fin whales Balaenoptera physalus was conducted around Elephant Island and the South Orkney Islands on board a CCAMLR fishing survey for fin fish in January and February 2016. Collected data were used for m
