Humpback Project Start / Knølhval i fokus

Right now, the fishing for herring is in full swing along the coast of Northern Norway. The herring does not, however, only attract fishermen, but also humpback whales and orcas who turn up to feast on the fish.

As a marine biologist, I started up a project in 2010/2011 to collect photos for photo-identification of humpback whales in Norway - a project that has grown enormously since the start and with interesting results starting to emerge about the ecology and migration patterns of humpbacks in Norwegian waters.


The last Sun of the year? The Polar Darkness period starts 21 November here in Tromsø

This winter I continue my data-collection of fluke-photos for the North Norwegian Humpback Whale Catalogue (NNHWC) as usual, but this year it will also form a part of a larger mulitidisciplinary research project here in Tromsø in Northern Norway with focus on oceanography, fish-stock size estimates using hydroacoustics and testing out of new techniques to monitor this species.


Monitoring pelagic fish at 70kHz and 200kHz

Because no two humpbacks look exactly the same (the flukes have various patterns and markings) the pictures can be used in much the same way as human fingerprints to identify individual whales. If enough pictures from various places are collected over long time, the same individuals may be seen several times and one can start to get an idea of e.g. migration patterns and the population size.

HAVE YOU PHOTOGRAPHED THE FLUKE/TAIL OF A HUMPBACK? PLEASE CONTACT THE NORTH NORWEGIAN HUMPBACK WHALE CATALOGUE (NNHWC) AT: whaleobs@akvaplan.niva.no


 
Unique humpback fluke - accompaigned by two orcas

Already from the first trip, we were able to identify approximately ten different humpback whales. I will present the scientific results in future posts - this is only be a pure photographic gallery with photos shot from the boat while the hydroacoustician run some test transects showing us dense balls of herring - and the feeding humpbacks were not far away.

  1. Fantastic images from this trip Fredrik :-) Very exciting information you and your colleagues around the world are gathering from the project.

  2. Fina bilder Fredrik! Du jag har en idé, skulle du kunna lägga upp ett litet chattfönster här på sidan så att de som är inloggade för stunden kan chatta med varandra? Kunde vara mysigt när man sitter här på natten och tittar på jordgloben och ser att det kan finnas någon mer inne samtidigt. :)

  5. Flott serie og spennende prosjekt. Bilde nr. 10 er både teknisk og komposisjonmessig veldig bra synes jeg!

  7. Dette er jo bare helt herlig Fredrik!! Skulle gjerne vært med en gang! Alle bilder er herlige, og min personlige favoritt er faktisk 3dje siste bilde, der hvor du bare ser skyggen igjennom gyllent vann...fantastisk bilde.
