This is it! We have disembarked in Tromsø and are heading home after a very successful and enjoyable expedition on RV #Polarstern! Many thanks to the crew, chief scientist and colleagues for making this possible! #PS143/1 #Arctic @awi

Land ho! 🫡
So nice to see and smell land again as #Polarstern steams towards Tromsø! #PS143/1 @awi

Yesterday afternoon, we started our way south to Tromsø, where most scientists and crew will disembark from #Polarstern. #PS143/1 was a very successful & fun expedition, but now I am looking forward to green spaces, family & friends and 🥬🍅🥒!
🤞for a calm passage! #Arctic @awi

The last action of #PS143/1 was successful: our crawler was safely deployed on the seafloor and the ROV visit shows that it is crawling and that its benthic chambers were lowered into the sediment and began the first cycle of oxygen measurements, one of many to come during the year-long deployment. Every 10 days, the crawler will make a new measurement and will then move for 10 m 🤞.

Sad find but positive outcome?! During the last dive at the HAUSGARTEN central station (~2500 m), the ROV found a bundle of many different #plastics related to fisheries & brought it up. I found at least nine different species entangled in this discarded bundle! #PS143/1 #Arctic

Another night, another camera deployment on the seafloor of our southernmost #HAUSGARTEN station (~2300 m), which is most influenced by Atlantic waters. All our #TimeSeries stations are now completed for this year 🖐️! #PS143/1 #Arctic @awi

Enjoying a spot of sunshine after days of fog, as we proceed to our next station ! 🧊☀️❄️

Quite spectacular views as our OFOBS camera system is heading down into the Molloy Deep, the deepest known point of the #Arctic (~5500 m)! 😮

It was nerve-wracking yesterday to see if the ice would move away from our central HAUSGARTEN, but it did 🤗! So, I am super excited to sample my experiments deployed 9 years ago to study plastics impact on organisms & biogeochemistry of the seafloor,a prime plastic sink. #PS143
