Please note: Abstract created by PANGAEA data editor using Jungblut et al. (2017). Marine top predators (seabirds, marine mammals and other megafauna) were counted during POLARSTERN cruise PS83 (ANT-XXIX/10) passing the east Atlantic from Cape Town to Bremerhaven in spring 2014. Continuous half-hour transect counts were conducted by two observers from the bridge, situated approximately 18 meters above sea level, throughout daylight hours and while the vessel maintained its traveling speed (see Joiris & Falck 2011).
