Drone flying between ice stations

This article is part of the series “2023-06: Arctic Ocean cruise KPH”.

The 3rd ice station st4 (78°50′ N 006°30′ W), was finished yesterday. Tomorrow we will start the 4th ice station st9 (78°50′ N 004° W) on our scientific cruise. The journey led us to the Fram Strait instead of north of Svalbard. That was because we could not break through the surprisingly thick multiyear ice to get further north.

Right now we are at 78°46’N 5°00’W, engines off. We drifted with almost 1 knot southeast and just in the moment while I am writing this sentence we start actively moving again heading more or less eastwards to st9.

After we had left the ice station we first headed to 8° W yesterday evening and then took a CTD cast each degree in longitude. 8° W, 7° W, 6° W and just now 5° W. A CTD measures amongst others salinity and temperature of the water column and also takes water samples from different depths. Since the last station was in deeper water (round 900–1000 m) the CTD cast took time. Time to use my private drone to fly a bit around. Since I do not need any compass calibration and such to just take some snapshots I could start and land it from the helicopter deck. Of course I asked the captain first.

Here are some shots from the ship in the ice from different directions.

About yesterday’s ice station I will a write later. Tomorrow I might be quite busy.

It is still a bit special to be in the Arctic and have better internet than a lot of populated places in Germany. On the cruise last year we only had a shared email address using Iridium for sending text messages and occasionally a tiny image. Now internet became normal on board. Yes, it makes many things much easier but I also feel a bit of nostalgia. It felt nice somehow to be far away from daily life for a while on last years cruise.
