whale club. She also works with whale watching companies (Arctic Whale Tours) to study the whales in Vesteralen and Tromsoe_
2016 Marine Mammal acoustic course studying the anthropocentric disturbances in Husavik, Iceland.

2015 research assistant Dolphin Communication Project studying tactile communication in Atlantic spotted dolphins and bottlenose,

dolphins in the Bahamas.She has always loved the ocean since she was a small girl growing up in southem California. She decided to pursue her passion ofmarine biology and moved to Norway in 2010 to study a Bachelor of Science Degree in Biology at the University of Nordland Shestarted working with Dr. Vester / OceanSounds in 2012 on her bachelor thesis on Killer Whale Photo-ID and completed her degreein 2012. She further pursued working with OceanSounds on her master thesis studying the vocal behavior and distribution of theAtlantic white-sided dolphins in northern Nomay. Her Master project was supported by Lofotrådet / Bo i LofotenlSince 2017 she is running Ocean Sounds Noway with her husband Bjorn in Bodo.

Bjørn Hamran

Director of Ocean Sounds Norway

2015 research assistant Dolphin Communication Project studying tactile communication in Atlantic spotted dolphins and bottlenose,

Director of Ocean Sounds Norway, Captain in the air, boat captain at sea.

When he is not flying for the airline, he can often be found out at sea driving the boat providing safe passage for the researchers, as well as taking photographs and operating the drones.


Nicola Rehn 

Biologist I Assistant Director of Ocean Sounds

Biologist — Specialized in bioacoustics and behaviour of marine mammals
Nicola is a German behavioural biologist and specialized in killer whale bioacoustics and behaviour. She started working With Heike
and Ocean Sounds in June 2016.
Nicola has a Master of Science degree from the University of Hamburg, Germany, and wrote her Master's thesis on the
vocalizations and behaviour of killer whales in the North Pacific In the year 2000 she started research on killer whales and worked
as an independent biologist on several marine mammal projects in Canada, Scotland and Germany since then.
When she heard killer whales the first time on a hydrophone, during her stay on a small uninhabited Canadian island; she

immediately wanted to know more about the communication and the behaviour of these fascinating animals. This moment wasvery special because there was absolutely no boat noise during the hydrophone recording; only the beautiful calls of killer whales.She is still fascinated every time she hears marine mammal vocalizations because we still know so very little about theircommunicationCurrently, Nicola is updating Ocean Sounds photo-ID catalogue of the Norwegian killer whale population together with MaditaZetzsche.Nicola is helping Ocean Sounds in Germany.

Madita Zetzsche 

Biologist I Assistant Director of Ocean Sounds 

German, came for the first time to Norway in 2006 for holidays and met Heike & Ocean Sounds and has been an assistant since. 
During her summer breaks from school she helped Oceans Sounds during 2007; 2008, 2009, 2011 2012 and 2014. Her work with 
Ocean Sounds inspired Madita to leam more about bio-acoustics and she volunteered at the archive for animals sounds / HU 
She is now conducting her PhD in Biology at the University of Leipzig. 
She is curating the OceanSounds Killer Whale Photo-ID project.

Felipe Matos


Biologist I Assistant of Ocean Sounds

Brazilian who moved to Nomay in 2008, got a bachelor's degree in Biology at the University of Nordland in Bodø in 2013.
2015 Master in Marine Ecology at the University of Nordland in Bodø. His project in partnership with Dr. Vester / Ocean Sounds
was to study distribution of Marine Mammals in the VestfJorden from 2006 — 2014 using data acquired by DL Vesterv and correlate
this data with sea temperature; fishing, whale hunting, sonar activity, and seismic surveys.
The goal was to monitor marine mammal abundance and see how human activity may or may not have influenced whale
distribution in the fiord, and how it changes over time.
His project was supported by Lofotrådet / Bo i Lofotenl
"Distribution of cetaceans in Vestjorden, Norway, and possible impacts of seismic surveys"
Master thesis by Felipe Matos, Faculty of Biosciences and Aquaculture, University of Nordland
May 2015
Currently Felipe helps Ocean Sounds with GIS maps and distribution studies.

Prof. Dr. Giovanna Bertella

From the beautiful Tuscany (Italy), Giovanna moved to Northern Norway in 1999 She gained a PhD at the Department of
Sociology Political Science and Community Planning at the Unversity of Tromsø in 2011. She is now employed at the School of
Business and Economics at LliT The Arctic University of Norway, Tromsc Among her research interests is the use of animals in
tourism from an experiential and ethical perspective, and the related management challenges and possibilities. She has been
studied whale watching in Northern Norway since the booming of the sector in 2011 _
Giovanna offers her expertise to support Ocean Sounds in investigating and identifying best tourism practices to design and
manage responsible encounters with marine mammals.
