Cool that you found us! This is the blog of the expedition DYNAMET SO299 to Papua New Guinea from 6th June to 29th July 2023. Currently, we are on our transit from Townsville/Australia into our working area near the island of New Ireland. For further detailed information about the goals and objectives of this scientific […]
by Dr. Julia Otte, AWI and Jessica Volz, AWI (deutsch s. u.) What gravity cores can tell us about the biogeochemistry of the Deep The deep sea has fascinated mankind since the early odysseys across the oceans – many myths have been told about the depths of the sea with the dreaded Kraken and Moby […]
by Elena Schiller, AWI (deutsch s. u.) Essentials of deep-sea research technology: The first thing I learnt upon entering a deep sea technology workshop was “non-corrosive steel is non-corroded on the day of delivery”, which leads me to my first topic: materials. We tend to avoid most metals because seawater is highly corrosive. So we […]
by Tasnim Patel, RBINS Life in the deep-sea is no picnic and dedicating your life to studying our last truly unexplored wilderness isn’t easy either. To sample fauna in the abyssal plains requires courage, expertise, commitment, financial backing and in my case …a pinch of luck. I’m studying deep-sea scavenging crustaceans, which are not only […]
by Dr. Freija Hauquier, Ghent University Underneath the seafloor lies an entire world of small animals crawling between the sediment grains, well hidden from the human eye at first glimpse. Yet they are numerous, diverse, and equally deserve our attention in the context of deep-sea mining. Sure, studying them requires a bit more patience than […]
by Henko de Stigter (Royal Netherlands Institute for Sea Research, NIOZ) Until somebody came up with the idea of mining polymetallic nodules from the abyssal depths of the Pacific Ocean, this place was one of the remotest and quietest on our planet. Far away from the brute natural forces of storms, floods, landslides, tsunamis and […]
by Dr. Sven Rossel, Katja Uhlenkott und Ann-Kathrin Weßel (deutsch s.u.) “Ah, you’re playing with mud again.” That is something biologists and geologists hear quite often on board. And yes, we are one of the parties “playing with mud”. But actually we, the biologists from Senckenberg, German Centre for Marine Biodiversity Research, are not interested […]
(Deutsche Version unten) How do you plan research that is to be conducted at the seafloor in 4000 meter water depth? How do you choose the locations for your studies in a large area that you may not know much about yet? How do you pick the best spot to deploy sensors? – Which path […]
(English version below) Das war eine häufige Frage an Bord zu Beginn unserer Forschungsfahrt. Denn das „Eddy“ Teil unserer wissenschaftlichen Untersuchungen wird, ergab sich relativ kurzfristig. Eddies sind temporäre Wasserwirbel mit einem Durchmesser von mehreren hundert Kilometern, die lange Strecken durch den offenen Ozean zurücklegen können, bevor sie sich irgendwann auflösen. Sie können von der […]
(English version below) Tief, fremd und unbekannt: So wird die Tiefsee häufig beschrieben. Die meisten der Tiere in der dunklen Tiefseeebene 4000 Meter unter unserem Schiff sind bisher unentdeckt und nur wenige wurden wissenschaftlich beschrieben. Hier möchten wir einige der Arten vorstellen, die wir während der Fahrt SO268 bereits entdeckt haben oder von denen wir […]
