Was #Fischerei mit #Plastik im #Ozean zu tun hat:
Der #Hausgarten ist ein 2500 m tiefes Areal im Nordpolarmeer.
Auch in solch entlegenen Gegenden sind Fischereinetze zu finden. Hier hatten sich darin bereits 9 unterschiedliche Arten verfangen.

The last action of #PS143/1 was successful: our crawler was deployed on the seafloor and the ROV visit shows that it is crawling and measuring 🤗. During the year-long deployment, the crawler will make a new measurement and will then move for 10 m every 10 days🤞.

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

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

Nice views ☀️🧊 as the CTD is going into the water to measure salinity, temperature, depth, chlorophyll and oxygen profiles throughout the water column and take water samples at defined depths for further analyses that‘ll keep us busy for hours to come.

Please consider supporting the "Tax-the-Rich" initiative to finance climate protection. If this EU citizens' initiative reaches certain thresholds, it must be considered . A powerful tool if it is used.

Bitte unterstützt "Tax-the-Rich" Initiative ! Es gilt Superreiche zu besteuern um mehr Klimaschutz zu finanzieren. Wenn diese EU-Bürgerinitiative bestimmte Schwellenwerte erreicht, muss sie geprüft werden. Ein mächtiges Tool, wenn es genutzt wird.

ROV Kiel6000 is in the water for its 1st mission to collect sediment samples in a lander-based mesocosm experiment (1500m depth) that had started in 2023 to study the impact of #Oceanacidification (#climatechange) on small #deepsea organisms & biogeochemistry! #PS143

We focus on stations Hausgarten observatory like every year. In the next few weeks, we will finish off our stations and ROV work.

So excited to start our ROV work tomorrow 🤗! Today we got an introduction to the different parts, protocols & procedures from the ROV team of @GEOMAR_en! Remotely operated vehicles (ROVs) allow us to do very targeted sampling & in situ experiments on the deep seafloor. #PS143/1

The next cruise leg will focus more on pelagic sampling including year round moored sediment traps, RAS samples, Triaxos, and lots more . This leg is more focused on the seafloor.

This little flower from the abyss brightened my day: Bathycrinus cf. carpenterii, a species of filter feeding sea lily that are related to starfish and sea urchins and that is one of our Hausgärtners. Caught by multiple corer this specimen came up in great shape 🤗! #PS143/1

🚁 The first helicopter has left to take some of the scientists to Longyearbyen. It's sad to see them go 🙋 , but we're looking forward to the new arrivals from GEOMAR @www.helmholtz.de !

Nice to see land again as we steam towards Svalbard to exchange some personnel! Weather permitting, we hope to welcome the @GEOMAR_de ROV team on board tomorrow 🚁🤞. (ROV = remotely operated vehicle, dive robot)

On the eve of #midsummer (summer solstice), we were greeted by a beautiful halo 🤩!
🧐 It is a ring or light that forms around the sun as sunlight refracts off ice crystals in a thin veil of cirrus clouds.

It was a glorious morning until this sea ice with a piece of #plastic drifted by. Sights like this - especially in such a remote part of our planet - will never cease to sadden me 😔.

🐻‍❄️ We‘re definitely in polar bear country now: the earlier sighting was actually 3, a mother and her two cubs. And just now we saw another bear! 🥰

Today, we have already much more sea ice floes around us - and quite logically we have just seen the first two polar bears 🐻‍❄️! No photo to share unfortunately, as they were too distant. Let’s hope for more sightings 🤞 #PS143/1
