Assessing the cleanup efforts at the historically polluted site in the Port of Liepaja, Karosta Channel.
Dobrotă, Alexandru-Sebastian (Master thesis, 2024)The presence of persistent contaminants in the sediments, such as heavy metals and hydrocarbons, can have long-lasting negative effects on marine ecosystems, resulting in harming both wildlife and humanity. It is critical ... -
Detection and Analysis of Microplastics in Boat Marina and Eelgrass Bed on the Southern Coast of Norway
Kim, Yeon-Jun (Master thesis, 2023)Microplastics are widely distributed around the world and are emerging as one of the most serious environmental problems worldwide. This study aimed to investigate the presence and sources of microplastics by human activities ... -
Macrofaunal colonization of mine tailings impacted sediments
Trannum, Hilde Cecilie; Næss, Rita; Gundersen, Hege (Peer reviewed; Journal article, 2020)An experiment was conducted to study and compare macrofaunal colonization of thin layers of mine tailings. Experimental boxes filled with marine sediments capped with mine tailings were placed on the seabed and subject to ... -
New insights into submarine tailing disposal for a reduced environmental footprint: Lessons learnt from Norwegian fjords
Ramirez-Llodra, Eva; Trannum, Hilde Cecilie; Andersen, Guri Sogn; Baeten, Nicole; Brooks, Steven; Escudero-Oñate, Carlos; Gundersen, Hege; Kleiv, Rolf Arne; Ibragimova, Olga; Lepland, Aivo; Nepstad, Raymond; Sandøy, Roar; Schaanning, Morten; Shimmield, Tracy; Yakushev, Evgeniy; Ferrando-Climent, Laura; Høgaas, Per Helge (Peer reviewed; Journal article, 2022)Submarine tailing disposal (STD) in fjords from land-based mines is common practice in Norway and takes place in other regions worldwide. We synthesize the results of a multidisciplinary programme on environmental impacts ... -
Riverine impacts on benthic biodiversity and functional traits: A comparison of two sub-Arctic fjords
Mcgovern, Maeve; Poste, Amanda; Oug, Eivind; Renaud, Paul E.; Trannum, Hilde Cecilie (Peer reviewed; Journal article, 2020)Climate change is leading to increases in freshwater discharge to coastal environments with implications for benthic community structure and functioning. Freshwater inputs create strong environmental gradients, which ... -
Three decades of change in the Skagerrak coastal ecosystem, shaped by eutrophication and coastal darkening
Frigstad, Helene; Andersen, Guri Sogn; Trannum, Hilde Cecilie; Mcgovern, Maeve; Naustvoll, Lars Johan; Kaste, Øyvind; Deininger, Anne; Hjermann, Dag Øystein (Peer reviewed; Journal article, 2023)Global coastal ecosystems are under accelerating pressure from human activities and climate change. In this study we explore a long-term time series (mostly 1990–2016) from major Norwegian rivers, together with coastal ... -
Time trends of heavy metals and PAHs in blue mussels (Mytilus edulis) and contamination of sediments in the Kristiansandfjord, Southern Norway
Skjeggestad, Camilla Jantina (Master thesis, 2023)The Kristiansandfjord in Southern Norway has been contaminated for several decades (Green et al., 1985; Berge et al., 2007; Øxnevad et al., 2021). In this study, contaminant concentration data from blue mussel and sediments ...
