🐋 Sea ice disappearing in East Greenland allows whales to move into previously inaccessible areas, increasing access to capelin and krill resources. Now, as climate change warms the sea and melts the ice, a new world opens up to them. Paper attached in thread 🌏🧪 #marineecology @au.dk

Giant whales move into Greenland waters as ice disappears
Melting sea ice from climate change has opened up the region for giant whales to undertake "feeding frenzies".

Our recent study in Ecological Modelling shows that southern right whale mother-calf pairs leave calving grounds once calves reach ~8 m in length, not after a fixed time. Larger, fatter mothers help calves reach departure size faster! 🐋⚡ Read it here: www.sciencedirect.com/science/arti... 🌐🌏🌱🧪

We are underway with the retrieval of detached data storage tags in the #WaddenSea 🇩🇰🦭 See photo captions and previous posts on our page for the building of retrievable tags and their deployment @au.dk #Science #biomonotoring #research #marineecology #marinemammalreasearch 🌐
Deployment of satellite tags on animals has the advantage of the electronics doing the datasampling. Positions, dive depths and underwater 3D movements can be collected for days, weeks and even months.In some cases larger data amounts are being sampled, and the amount of data is too large to transmit to a satellite. Instead, the floating tags need to be recovered after detaching from the animal.Retrieving tags, unless they are being found by people on the beach, can be quite time-consuming. However, with the help from radio transmitters the access to important research data is a great reward for the invested time and logistics.

My colleagues at AU ecoscience do amazing things with the Arctic Monitoring Assessment Program. AMAP constantly works to update reports on the status of a changing Arctic Environment. They also make readable summaries for policy makers, also informative and interesting for everyone. www.amap.no
