While other sponges use an aquiferous ... -
Deep-sea sponge grounds as nutrient sinks: Denitrification is common in boreo-Arctic sponges
Rooks, Christine; Fang, James Kar-Hei; Mørkved, Pål Tore; Zhao, Rui; Rapp, Hans Tore; Xavier, Joana R; Hoffmann, Friederike (Peer reviewed; Journal article, 2020)Sponges are commonly known as general nutrient providers for the marine ecosystem, recycling organic matter into various forms of bioavailable nutrients such as ammonium and nitrate. In this study we challenge this view. ... -

Meyer, Heidi Kristina; Roberts, Emyr Martyn; Mienis, Furu; Rapp, Hans Tore (Peer reviewed; Journal article, 2020)The Sognefjord is the longest (205 km) and deepest (1308 m) fjord in Norway, and the second-longest in the world. Coast-fjord exchange in Sognefjord is limited by a seaward sill at 170 m water depth, which causes a clear ... -
A New Species of Osedax (Siboglinidae: Annelida) From Colonization Experiments in the Arctic Deep Sea
Eilertsen, Mari Heggernes; Dahlgren, Thomas Gunnar; Rapp, Hans Tore (Peer reviewed; Journal article, 2020)Large parcels of organic matter in the deep sea, such as whale carcasses, harbor a very specialized fauna, most famously the bone-eating worms in the genus Osedax (Annelida, Siboglinidae). Although Osedax was first described ... -
Spatial patterns of arctic sponge ground fauna and demersal fish are detectable in autonomous underwater vehicle (AUV) imagery
Meyer, Heidi Kristina; Roberts, Emyr Martyn; Rapp, Hans Tore; Davies, Andrew J (Peer reviewed; Journal article, 2019)Deep-sea sponge grounds are important habitats that provide several ecosystem services, yet relatively little is known about their distribution and ecology. While most surveys have focused on the broad-scale distribution ...
