The important role of sponges in carbon and nitrogen cycling in a deep-sea biological hotspot
Hanz, Ulrike; Riekenberg, Philip; de Kluijver, Anna; van der Meer, Marcel; Middelburg, Jack J.; de Goeij, Jasper M.; Bart, Martijn C.; Wurz, Erik; Colaço, Ana; Duineveld, Gerard C. A.; Reichart, Gert-Jan; Rapp, Hans Tore; Mienis, Furu (Journal article; Peer reviewed, 2022)Deep-sea sponge grounds are hotspots of biodiversity, harbouring thriving ecosystems in the otherwise barren deep sea. It remains unknown how these sponge grounds survive in this food-limited environment. Here, we unravel ... -
Long-term Observations Reveal Environmental Conditions and Food Supply Mechanisms at an Arctic Deep-Sea Sponge Ground
Hanz, Ulrike; Roberts, Emyr Martyn; Duineveld, Gerard; Davies, Andrew; van Haren, Hans; Rapp, Hans Tore; Reichart, Gert-Jan; Mienis, Furu (Journal article; Peer reviewed, 2021)Deep-sea sponge grounds are hotspots of benthic biomass and diversity. To date, very limited data exist on the range of environmental conditions in areas containing deep-sea sponge grounds and which factors are driving ... -
On giant shoulders: how a seamount affects the microbialcommunity composition of seawater and sponges
Busch, Kathrin; Hanz, Ulrike; Mienis, Furu; Mueller, Benjamin; Franke, Andre; Roberts, Emyr Martyn Tomas; Rapp, Hans Tore; Hentschel, Ute (Journal article; Peer reviewed, 2020)Seamounts represent ideal systems to study the influence and interdependency of environmental gradients at a single geographic location. These topographic features represent a prominent habitat for various forms of life, ... -
Seasonal Variability in Near-bed Environmental Conditions in the Vazella pourtalesii Glass Sponge Grounds of the Scotian Shelf
Hanz, Ulrike; Beazley, Lindsay; Kenchington, Ellen; Duineveld, Gerard; Rapp, Hans Tore; Mienis, Furu (Journal article; Peer reviewed, 2021)The Scotian Shelf harbors unique aggregations of the glass sponge Vazella pourtalesii that provides an important habitat for benthic and pelagic fauna. Recent studies have shown that these sponge grounds have persisted in ...
