Whale sightings during POLARSTERN cruise PS125

Data on whale distribution and abundance in the polar oceans is rather sparse, as implementing the standard surveying method, line-transect surveys, is challenging and costly. To overcome this problem, we initiated a program to electronically log all opportunistic cetacean sightings during all Polarstern expeditions through the nautical officer on watch. Opportunistic (visual) sightings by naked eye were logged during Polarstern Cruise PS125 (Port Stanley – Bremerhaven) by the nautical officer on duty using a customized Software package (WALOG, WhAleLOGger) installed on a touch screen laptop located on the ship's bridge. Species were identified by naked eye or handheld binoculars (7x50) to the lowest possible taxonomical level and assigned a "certainty" level of identification. The number of animals were counted if possible or estimated for larger groups. Whenever identification to species level was not possible, the next identifiable taxonomical category was assigned. Information on sighting position, date and time are automatically transferred from the ship's DAVIS-Ship System (https://dship.awi.de/) to the WALOG software at the time of logging. Photographs were taken, if possible, for retrospective analysis. All data of acquired sightings were retrospectively validated by a marine biologist and converted to a standard format. To this end, plausibility of sighting time, location, standardization of species names, eventual comments added at the time of sighting, as well as additional information such as photographs (if available) were checked either to verify or improve species identification. Datasets are used in species distribution modelling and to inform interested parties about occurrences.

Whale sightings during POLARSTERN cruise PS145/1

Data on whale distribution and abundance in the polar oceans is rather sparse, as implementing the standard surveying method, line-transect surveys, is challenging and costly. To overcome this problem, we initiated a program to electronically log all opportunistic cetacean sightings during all Polarstern expeditions through the nautical officer on watch. Opportunistic (visual) sightings by naked eye were logged during Polarstern Cruise PS145/1 (Bremerhaven – Las Palmas) by the nautical officer on duty using a customized Software package (WALOG, WhAleLOGger) installed on a touch screen laptop located on the ship's bridge. Species were identified by naked eye or handheld binoculars (7x50) to the lowest possible taxonomical level and assigned a "certainty" level of identification.

Counts of seabirds, marine mammals and other megafauna during POLARSTERN cruise PS83 (ANT-XXIX/10)

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). Due to the width of the bridge, observations were limited to a 90° angle from the bow to one side, as it was impractical for one observer to simultaneously cover both sides. Species were initially identified with the naked eye and confirmed using binoculars (8 – 10 times magnification). Photos were used in retrospect to help identify rare or hard to classify specimens. Individuals following or circling around the ship were only counted once in a 30 min interval (i.e. during one 'transect count'). Water temperature and salinity were continuously and automatically recorded by a thermo-salinometer installed at the keel of the Polarstern (approximately 10 meters below sea level). Depth data were obtained either from the vessel's echosounder or hydrosweep. Data extraction was carried out from the DShip data system on board.

Counts of seabirds, marine mammals and other megafauna during POLARSTERN cruise ANT-XXVIII/1

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 ANT-XXVIII/1 passing the east Atlantic from Bremerhaven to Cape Town in fall 2011. 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). Due to the width of the bridge, observations were limited to a 90° angle from the bow to one side, as it was impractical for one observer to simultaneously cover both sides.

Marine top predators (seabirds, marine mammals and other megafauna) were counted during POLARSTERN cruise ANT-XXIX/1 passing the east Atlantic from Bremerhaven to Cape Town in fall 2012. 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).

Analyse der Mikroplastikbelastung von Meeressäugetieren aus der Arktis

Das stetig steigende globale Mikroplastik-Vorkommen bezieht auch das empfindliche Ökosystem der Arktis mit ein. Die AMAP-Arbeitsgruppe des Arktischen Rates zielt deshalb darauf ab, ein reguläres Monitoring zu etablieren, welches sowohl die Entwicklung der Mikroplastikbelastung erfasst als auch die Auswirkungen auf das Ökosystem überwacht. Für diesen Zweck ist es erforderlich grundlegende Informationen zu sammeln und ein standardisiertes Monitoring zu entwickeln, um durch eine längerfristige Datenerhebung Entwicklungen zu erfassen und negative Veränderungen mit effektiven Maßnahmen entgegenzuwirken. Monitoring an Tierpopulationen erfolgt derzeit an Seevögeln und Fischen. Marine Großsäuger und insbesondere Top-Prädatoren (die der indigenen Bevölkerung teilweise auch noch als Nahrungsgrundlage dienen) wurden bisher weniger stark berücksichtigt, sind jedoch auch für die AMAP-AG von Interesse und Bedeutung. Innerhalb des Projektes werden repräsentative Arten der Arktis untersucht: Wale, Robben, Eisbären und Otter. Die Probennahme geschieht in Kooperation mit arktischen Partnern und zielt darauf ab Daten zur Mikroplastikbelastung der Tiere zu generieren.
