Effects of submarine mine tailings on macrobenthic community structure and ecosystem processes
Trannum, Hilde C; Gundersen, Hege; Escudero-Oñate, Carlos; Johansen, Joachim T; Schaanning, Morten T (Journal article; Peer reviewed, 2018)A mesocosm experiment with intact benthic communities was conducted to evaluate the effects of mine tailings on benthic community structure and biogeochemical processes. Two types of tailings were supplied from process ... -
Epifaunal and infaunal responses to submarine mine tailings in a Norwegian fjord
Trannum, Hilde C; Borgersen, Gunhild; Oug, Eivind; Glette, Tormod; Brooks, Lucy; Ramirez-Llodra, Eva (Journal article; Peer reviewed, 2019)Disposal of mine tailings in marine shallow water ecosystems represents an environmental challenge, and the present paper reports results from a field study in Frænfjorden, Norway, which is subject to such disposal. ... -
Long-term response of marine benthic fauna to thin-layer capping with powdered activated carbon in the Grenland fjords, Norway
Trannum, Hilde C; Raymond, Caroline; Næss, Rita; Borgersen, Gunhild; Gunnarsson, Jonas S; Schaanning, Morten T (Peer reviewed; Journal article, 2021)The Grenland fjords in Norway have a long history of contamination by large emissions of dioxins and mercury. As a possible sediment remediation method in situ, thin-layer capping with powdered activated carbon (AC) mixed ... -
Recolonization and recovery of an Arctic benthic community subject to mine-tailings deposits
Trannum, Hilde C; Pedersen, Kristine B.; Renaud, Paul E; Christensen, Guttorm N.; Evenset, Anita (Peer reviewed; Journal article, 2023)Deposition of large volumes of mine tailings takes place in several Norwegian fjords, but the impacts on marine ecosystems have received relatively little scientific attention. At a 40 + −year old tailing deposition area ...
