Field experiment on thin-layer capping in Ormefjorden and Eidangerfjorden; Benthic community analyses 2009-2011
Schaanning, Morten; Beylich, Bjørnar; Samuelsson, Göran; Raymond, Caroline; Gunnarsson, Jonas; Agrenius, Stefan (NIVA-rapport;6257, Research report, 2011)As part of the work towards a remediation plan for the Grenlandfjord area, thin cap test fields were established at 30 and 100 m depth in the outer Grenlandfjord in September 2009. One field was treated with crushed ... -
Impaired benthic macrofauna function 4 years after sediment capping with activated carbon in the Grenland fjords, Norway
Raymond, Caroline; Samuelsson, Göran S.; Agrenius, Stefan; Schaanning, Morten T; Gunnarsson, Jonas S. (Peer reviewed; Journal article, 2021)The sediments in the Grenland fjords in southern Norway are heavily contaminated by large emissions of dioxins and mercury from historic industrial activities. As a possible in situ remediation option, thin-layer sediment ... -

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 ... -
Response of marine benthic fauna to thin-layer capping with activated carbon in a large-scale field experiment in the Grenland fjords, Norway
Samuelsson, Göran S.; Raymond, Caroline; Agrenius, Stefan; Schaanning, Morten; Cornelissen, Gerard; Gunnarsson, Jonas S. (Journal article; Peer reviewed, 2017)A field experiment with thin-layer capping was conducted in the Grenland fjords, Norway, for remediation in situ of mercury and dioxin-contaminated sediments. Experimental fields at 30 and 95 m depth were capped with (i) ... -
Thin layer capping of fjord sediments in Grenland. Chemical and biological monitoring 2009-2013
Schaanning, Morten; Beylich, Bjørnar; Raymond, Caroline; Gunnarsson, Jonas S. (NIVA-rapport;6724, Research report, 2014)A field experiment on thin layer capping was initiated in the Grenland fjords in September 2009. A primary objective of the field experiment was to assess the capacity of the different cap designs to reduce bioavailability ... -
Undersøkelser av kjemisk utlekking og biota på testfelt på sjøbunnen i Grenlandsfjordene 2018-2019
Schaanning, Morten; Trannum, Hilde Cecilie; Beylich, Bjørnar; Raymond, Caroline; Størdal, Ingvild Fladvad (NIVA-rapport;7432, Research report, 2019)Denne rapporten beskriver overvåking av spredning og biotilgjengelighet av dioksiner (PCDD/F), heksaklorbenzen (HCB) og oktaklorstyren (OCS) i de ni årene fra etablering av testfelt for tynnsjikt-tildekking i Grenlandsfjordene ...
