How to prepare for an Arctic campaign (part 2)

Part of preparing for a climate study in the Arctic involves preparing for polar bear emergencies.  Blog followers will ask themselves: wait, but aren‘t we flying? Yes! But…safety training includes polar bear protection, as emergency landing on the ice is (an unlikely) possibility.

The ice is the home of the polar bears. Bears are very curious, and extraordinarily well adjusted to the Arctic environment. For a polar bear, a group of scientists means a great opportunity for some extra dinner. So even though many of us are faced by comments around „You‘re going to the Arctic: I hope you will see a polar bear“ we actually really want to avoid seeing one (other than from the plane).

But you never know, so better to prepare for the emergency case.  This is why 6 of us spent a day at AWI Bremerhaven to learn about polar bears and their behaviors.   We learned how to avoid meeting a bear, how to scare bears (hint: they don‘t like loud noises, including banging on cooking pots), and what to do when you see one from far away. For the troubling worst-case scenario of a bear attack, we were also trained on how to handle a rifle.

Insights from the group include: rifles are surprisingly heavy; we were lucky to have Arctic-like wind conditions as storm „Ylenia“ was passing the Bremerhaven area during our training; and fingers crossed for spotting a bear from the air!

How to prepare for a campaign in the Arctic?

During the past decades the Arctic climate is undergoing warming which impacts the local ecosystem and human infrastructure. To better understand the Arctic climate system and improve projections for the future, three aircraft will jointly observe various atmospheric processes over the North Atlantic near Spitsbergen during the HALO-(AC)³ campaign in March and April 2022.

Researchers from our group visited Bremerhaven for an exciting two-day safety training in preparation for this campaign. We learned, how to avoid dangerous encounters with polar bears which actually spend most of their lifetime on the sea ice beneath the aircraft. Additionally, an exhausting sea survival training demonstrated the use of life rafts and other equipment in case of an emergency landing. During the training huge waves and a thunderstorm were imitated, including flashes, rain and thunder in a complete dark surrounding.

Moreover, the first instrument belonging to our institute is already mounted below the aircraft Polar 5! It is a radar called MiRAC-A which will detect clouds below the aircraft. The Polar 5 will be equipped with several remote sensing instruments from different institutions. Our working group will additionally install the microwave radiometer HATPRO. Updates on this installation, the calibration of the instruments and the test flights will follow!
