The V0b tag deployment has started! Follow the MINTAG on its journeys with our Steering Group members deploying them on minke and fin whales in the North Atlantic and Pacific.

Tag fact: When tags have been deployed, it takes a few passes for the satellites to correctly estimate the location since it is based on at least 2 uplinks during a single satellite pass. Therefore, the first location can be depicted wrong, even though the system actually did come up with a location close to the deployment location, but it is incorrectly placed in the database. The satellites can often find multiple solutions depending upon how many uplinks they receive. Usually, the coordinates are correct after a few passes.
Deployment of 25 V0b tags - 2023
During the summer of 2023, 10 minke whale tags and 15 fin whale tags of the V0b generation will be deployed in the North Atlantic and North Pacific by four different groups.
Over the course of the summer, you will find here information on who is deploying the tags, in which areas they are deploying them and updates from the researchers themselves.

Japan: 5 fin whale tags, Sea of Okhotsk
On the 5th of June 2023, Japan started as the first country to test 5 V0b fin whale tags. Steering Group member Kenji Konishi and his team went to the southern Sea of Okhotsk off Hokkaido to tag the whales.
Vessel Chipashiri:
Kenji: Weather condition was good. We departed from Abashiri port at 06:00. Fin whales were not found in the area near shore, but several fin whales were found after two hours of searching. We deployed three MINTAGs and sampled skin tissue sample from one of the fin whales.
Kenji: Weather condition was super good when we departed from the port at 05:50. We could find fin whales earlier than during the survey on the 7th. We also found many Dall’s porpoises, bird’s beaked whales and shearwaters. We found four whales and deployed a MINTAG on a fin whale, but the weather turned too foggy and we lost visibility. We drifted for a while and started to search again, but we could not spot any fin whales.
Kenji: After a week of bad and foggy weather, we finally managed to deploy the last tag!
East Greenland: 5 fin whale tags, Angmassilik fjord
On the 8th of August 2023, Greenland started the second test of 5 V0b fin whale tags. Steering Group members Mads Peter Heide-Jörgensen and Rikke Guldborg Hansen as well as their team went to the Angmassilik fjord in East Greenland to tag fin whales.
The fjord is approximately 70 km long and 5 km wide. When you sail 50 km into the fjord you will arrive at the settlement called Kuummiut. There is a fish factory in town, a small supermarket, a school, a church and a community house and approximately 250 people call this place their home.

What makes the MINTAG project so exciting? Mads Peter tells you his answer to this question here:
Follow Rikke, Mads Peter and their team on their survey in East Greenland:
Rikke: I departed from Copenhagen and arrived in Kulusuk where Siggi (owner of the chartered boat) picked me up. We proceed to Tasiilaq to pick up Ababsi and the equipment that had arrived with ship a few weeks earlier.
We sailed onward to Kuummiut and arrived at 20:30. We saw fin whales in the fjord some kilometers from shore and immediately all pre-trip worries about finding fin whales vanished. Found the community house where we had rented a room.
Rikke: Ababsi and I calibrated the sight on the crossbow. Mads Peter arrived in the morning from Tasiilaq with the satellite tags. All tags found the correct location of Kuummiut and were re-activated when dropped in saltwater. The sight on the ARTS was calibrated and test shooting with both the carrier and the new tags were carried out in the evening. We saw some humpbacks and fin whales in the fjord in the afternoon while walking in the mountains.
Rikke: We left Kuumiut at 3 pm to search for fin whales. We went into the fjord Ikaasak where we saw a humpback feeding on capelin close shore. We found several fin whales and observed their behavior for some hours. Our boat was to slow for approaching and the closest we got was 50m.
Rikke: We left Kuummiut at 11:15 and found a couple of fin whales in the fjord west of the town. There was also a sperm whale. We tried for 1.45 hrs to chase the whales from Siggi’s dinghy (Poca 500, 115 hp Mercury) but the whales reacted and moved quickly away so this approach was cancelled for the rest of the day.
We thereafter moved to Ikerasak where we passed a humpback whale within shooting distance while at the same time two fin whales were right behind the boat. No shooting at that opportunity. The wind was picking up and creating waves so we had to move inside the fjord where we found up to five whales in the bay opposite Kuummiut. Apparently the whales are circling around in Ammassalik fjorden and occasionally return to certain coastal areas often very close to the beach where gulf feeding intensively is practiced. The feeding events are also obvious from the concentration of diving kittiwakes.
Rikke: We left Kuummiut at 14h. We went for the coast line where the locals say fin whales feed and waited there 2 hours but only saw humpback whales. We then went to the fjord Ikaasak but no luck there either. We saw two fin whales in the main fjord and tried to hunt them down but never came within shooting distance. We then had discussions on the next step, i.e. hiring a different boat.
Mads Peter: After having tried approaching the fin whales with different types of boats inshore in East Greenland we finally tried with dinghies offshore and managed to hit a fin whale with four out of five shots.
At least three of the shots seemed to penetrate and embed completely, but it was uncertain if they went too deep.

Norway: 5 fin whale tags, Kongsfjorden
On the 15th of August 2023, Norway started the third test of 5 V0b fin whale tags. Steering Group member Christian Lydersen and his team went to Kongsfjorden to tag fin whales.
