Cen­ter for Deep-Sea Re­search

Con­struc­tion work for the Cen­ter for Deep-Sea Re­search (ZfT) began in Feb­ru­ary 2021. Fundamental processes in the deep sea are to be investigated at the ZfT. Or­gan­iz­a­tion­ally, the ZfT will be loc­ated un­der the um­brella of the Re­search Fac­ulty MARUM.

Our col­league Volker Diekamp con­tinu­ously doc­u­ments the con­struc­tion pro­gress of the Cen­ter for Deep-Sea Re­search (ZfT) with his cam­era.

Deep Sea Moments

MARUM's Remotely Operated Vehicles (ROV) are in use in the oceans worldwide. On their way into the deep sea and at the bottom of the oceans, the researchers discover unique habitats with the help of the robots, encounter their inhabitants and experience very special Deep-Sea Moments again and again on their expeditions.

All Deep Sea Moments

Deep Sea Moments No. 4

Salt domes in the Campeche-Sigsbee Salt Province form domes, hills and ridge structures on the sea floor in the southern Gulf of Mexico. The Tsanyao Yang knoll is one of these and is home to a rich fauna of chemosynthetic organisms at a water depth of 3,100 meters. Beard worms, which occur here with mussels, snails and many other animals, use the methane hydrate deposits and their conversion products as a basis for life with the help of symbiotic microbes.

The white, massive-looking methane hydrates form a solid substance of methane and water that looks like ice and is only stable at high pressure and cold temperatures. The methane hydrates are formed by rising gas bubbles, whereby the bubble structure of the methane hydrates often remains intact and is inhabited by the so-called "ice worm". This species was previously only known from the northern Gulf of Mexico at shallower water depths and was discovered for the first time in the deep sea by MARUM researchers during the M114 meteor expedition.
