英文摘要	In relation to a possible cable pathway on the sea floor through the inner half of the Hardanger fjord, the Institute for Marine Research has carried out ROV inspections of the benthic faunal communities along 17 selected bottom transects. The surveyed area was restricted to the inner half of the Hardanger fjord – from Sima to Norheimsund in the period 9–29 November 2010. The deep horizontal seabed along the midline of the investigated part of the fjord was dominated by the crustacean Munida sp and its borrow, the sea cucumbers Bathyplotes sp and Stichopous sp, sea-pens, and the echiuran Bonellia sp. The steep walls along the sides of the investigated fjord were populated with less abundant but still relatively frequently-occurring taxa such the sea star Brisingia sp, the large bivalve Acesta sp, and several species of sponges. Though any local recovery time is unknown, we do not consider these populations to be threatened by the possible cable-laying activities. These are not listed in the Norwegian redlist and are not considered as threatened by the OSPAR Convention. However, in the outer part of the investigated area (transects named Kvamsøy cliff wall and Øystese), the vulnerable corals Lophelia pertusa and Anthomastus grandiflorus (redlisted) and Primnoa sp were observed. To avoid threatening impacts to these groups of corals, we therefore recommend using video monitoring during any cable-laying activities.
