Together with MSc student Oliver Nowak and local hunters, Fredrik Christiansen measured over 500 whales during March-June to investigate their prey consumption and condition.

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

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.

🔊Paper out today with @nature.com!

Despite decreasing emissions 🌏 mercury levels are rising in some species. Hg Isotopes could reveal why.

Our new research shows ocean currents, may now be the main source of mercury in Arctic ecosystems. 🌐🧪🐻‍❄️🐋 @au.dk

Stable isotopes unveil ocean transport of legacy mercury into Arctic food webs - Nature Communications

Mercury pollution in the Arctic has reached toxic levels. Here, the authors compile mercury isotope data from peat and aquatic predator species collected across Greenland over the past 40 years, obser...

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.
