Dedicated field studies
Over the years we also conducted some dedicated field studies, limited in scope and duration, to address specific questions like ....
2019 eDNA-PAM pilot Port Elizabeth, ZA
Pilot study by HIFMB-AWI off Port Elizabeth (South Africa) during which passive acoustic records and water samples for eDNA were simultaneously collected, this approach will allow direct comparison of species detections between both methods.
2016 - 2019 North Sea Pilot
Pilot study in collaboration with BioConsult Holstein. Deployment of an IcLIsten Recorder in the German North Sea, southwest of the Doggerbank from October 2016 - March 2019.
2015 & 2016 SAMBAY: San Antonio Model BAY for passive acoustic density estimation, ARG
As a a collaborative project between the OZA and the MaryBio Research Foundation in Patagonia, Argentina, SAMBAY analysed southern right whale behavior and acoustic propagation properties to estimate animal density from passive acoustic monitoring.
2014/15 Acoustic mensuration of RV Polarstern during expedition PS89 https://doi.org/10.2312/BzPM_0689_2015
To capture the sound field of RV Polarstern as experienced by a marine mammal close to the sea surface we recorded the ship's passage on two occasions with hydrophones dipped to 10m depth from a free drifting zodiac while RV Polarstern passed by at 10kns (Closest Point of Approach, CPA ca. 180m)
2013 Acoustic mensuration of cargo ship Nadezhda
To capture the sound emission of a fully powered POD drive, we conducted an acoustic mensuration of cargo ship Nadezhda while steaming. Recordings were taken using a bottom mounted icListen hydrophone and Reson TC4032 lowered from pilot vessel Döse.
2012/13 PASATA (PASsive Acoustic Tracking of Antarctic marine mammals)
The aim of the PASATA project was to use time-synchronized passive acoustic recorders to localize vocalizing marine mammals in the Atka Bay area. Alongside the passive acoustic recordings, on-ice and underwater camera systems were deployed near Weddell seal breathing holes as a pilot project to obtain additional visual information on this species' behavioural activity.

2009 Polarstern expedition ANT-XXV/2 https://doi.org/10.2312/BzPM_0595_2009
Deployment of 6 GPS tracked PALAOA-S recorders near Maud Rise. RESON TC4032 hydrophone connected to an M-Audio recorder. with solar panel.
2008 Polarstern expedition ANT-XXIV/3 https://doi.org/10.2312/BzPM_0606_2010
Deployment of 2 PALAOA-S recorders in Atka Bay. RESON TC4032 hydrophone connected to an M-Audio recorder in Zarges box.
2006 Polarstern expedition ANT-XXIII/6 doi:10.2312/BzPM_0580_2008
Test of a passive acoustic streamer towed behind Polarstern, sea ice based PAM for leopard seals for diver safety in the vicinity of Polarstern, and PAM recordings at a separate site 60nm from Polarstern for 12h at 192 kHz.
2005 Polarstern expedition ANT-XXII/3 https://doi.org/10.2312/BzPM_0533_2006
Test of a passive acoustic streamer towed behind Polarstern, deployment of 10 sonobuoys, deployment of 3 PODs in the Weddell Sea.
2003 Polarstern expedition ARK XIX/4 https://doi.org/10.2312/BzPM_0475_2004
Stationary acoustic mensuration of RV Polarstern and its hydroacoustic equipment at the Heggerness acoustic range in the Herdle Fjord, Norway. Acoustic measurements were conducted by the Wehrtechnische Dienststelle WTD71, who operated the range together with its European partners.
2002/3 Polarstern expedition ANT-XX/2
First trials of underwater recordings in Atka Bay.
PALAOA Satellite Recorders (to be completed)
