Resolving the interannual variability of phytoplankton community composition in Fram strait using ship-based high-frequency spectrophotometric measurements from 2015 to 2024 The Arctic is warming more than four times as fast as any other region of our planet. This warming has led to a dramatic decline in seasonal sea-ice c…

Major heat wave in the North Atlantic had widespread and lasting impacts on marine life From microorganisms to whales, ecosystems respond to an extreme event across all trophic levels.

🌡️ New study including data from our @awi.de #HAUSGARTEN observatory in the #Arctic #DeepSea shows that a 'Major heat wave in the North Atlantic had widespread and lasting impacts on marine life'. #ClimateChange increases #MarineHeatWave frequency.

Our new synthesis on the composition & dynamics of hard-bottom communities over 25 years #HAUSGARTEN observatory research, indicates they have short-range larval dispersal, low recruitment & slow growth, which suggests limited resilience to anthropogenic disturbance. @awi.de

Hausgärten als Treiber nachhaltiger Stadtentwicklung Hausgärten sind weit mehr als dekorative Randzonen um unser Zuhause. Mit rund 17 Millionen Parzellen in Deutschland – einer Fläche vergleichbar mit allen Naturschutzgebieten des Landes – bilden sie ein dichtes Geflecht natürlicher Inseln. Diese grüne Infrastruktur reguliert das Mikroklima: Verdunstung kühlt an heißen Tagen, Schatten spendende Bäume mildern Temperaturspitzen, und versickerndes Substrat puffert Starkregen, sodass Kanäle entlastet werden. Gleichzeitig fungieren Böden und Vegetation als CO₂-Senken und reduzieren so aktiv unseren ökologischen Fußabdruck.

Important new study on' Seasonal recurrence and modular assembly of an #Arctic pelagic marine microbiome' published by people of our @www.helmholtz.de #DeepSea Group ☺️:
It highlights again the value of sustained ocean observation such as our #HAUSGARTEN observatory!

2/2 Spatiotemporal changes in community composition show decreasing diatom abundance during warm anomalies, which would reduce the efficiency of a diatom-driven biological carbon pump and thus carbon sequestration in the #DeepSea.

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.

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

Great panoramic views from the 'Peildeck' as we steam through the ice 🧊❄️ to our northernmost #HAUSGARTEN station 🥰!

1/ Yay, this morning we arrived at the southernmost #HAUSGARTEN station S3! And: we already got our first sediment samples taken at ~2300m depth by our benthic work horse, the multiple corer 🥳.

Still steaming north to the AWI #Hausgarten Observatory in the #Arctic #DeepSea ☺️.
By now, all the equipment has been moved from the containers into our laboratories or onto the main working deck. Looking forward to getting started 🤗! #PS143

Yay: packing for Polarstern expedition #PS143 to AWI’s #HAUSGARTEN observatory in the #Arctic #DeepSea is completed! Everything’s ready for custom‘s before transport to the ship! Still, 3 weeks to go until departure.
