CLIMEX Project: Climate data for first year of treatment April 1994 - March 1995
(NIVA-rapport;3339, Research report, 1995)Climate change treatment began in April 1994 at the 2 experimental catchments. At KIM CO2 is increased (to 560 ppm) and air is heated (by 3¨ C in summer and 5¨ C in winter). At EGIL soil is heated. Except for an initial ... -
Climex project: Data report for June 1994 - May 1999
(NIVA-rapport;4157, Research report, 1999)CLIMEX project was conducted from May 1994 to June 1998 and involved whole ecosystem manipulation of temperature and CO2 at the catchment scale. Measurements of precipitation and runoff continued for one-year post-treatment ... -
CLIMEX project: Report on the second year of treatment May 1995 - December 1995
(NIVA-rapport;3526, Research report, 1996)CLIMEX is a integrated, whole-ecosystem research project studying the response of entire forested catchments to increased CO2 and temperature. These whole-catchment manipulation experiments are designed to allow quantification ... -
Climex project: Report on the third year of treatment, May 1996 - December 1996
(NIVA-rapport;3745, Research report, 1997)CLIMEX is an integrated, whole-ecosystem research project studying the response of entire forested catchments to increased CO2 and temperature. These whole-catchment manipulation experiments are designed to allow quantification ... -
CLIMEX project: Response of runoff chemistry after 2 years of elevated CO2 and temperature
(NIVA-rapport;3542, Research report, 1996)CLIMEX is an integrated, whole-ecosystem research project studying the response of entire forested catchments to increased CO2 and temperature. KIM catchment receives clean rain, elevated CO2 and elevated air temperature. ... -
CLIMEX project: Soil moisture monitoring and hydrological response
(NIVA-rapport;3554, Research report, 1996)This report describes the data obtained from the soil moisture monitoring programme and its application in determining catchment hydrological budgets. The hydrological response of the catchments is evaluated through modelling ... -
Co-occurrence, ecological profiles and geographical distribution based on unique molecular identifiers of the common freshwater diatoms Fragilaria and Ulnaria
(Peer reviewed; Journal article, 2022)Diatom taxonomy has evolved in recent years, with many new species described and new approaches such as molecular genetics showing the existence of cryptic diversity within currently accepted species. This cryptic diversity ... -
CO2 increases C-14 primary production in an Arctic plankton community
(Journal article; Peer reviewed, 2013)Responses to ocean acidification in plankton communities were studied during a CO2-enrichment experiment in the Arctic Ocean, accomplished from June to July 2010 in Kongsfjorden, Svalbard (78°56′ 2′′ N, 11°53′ 6′′ E). ... -
Coagulation of phosphorous and organic matter from marine, land-based recirculating aquaculture system effluents
(Peer reviewed; Journal article, 2021)Saline effluents from marine land-based aquaculture production can neither be disposed in common municipal wastewater treatment plants, nor disposed as landfill. Furthermore, stricter environmental regulations require the ... -
COASTAL HABITAT MAPPING WITH UAV MULTI-SENSOR DATA: AN EXPERIMENT AMONG DCNN-BASED APPROACHES

Coastal Research Seen Through an Early Career Lens—A Perspective on Barriers to Interdisciplinarity in Norway
(Peer reviewed; Journal article, 2021)The value of interdisciplinarity for solving complex coastal problems is widely recognized. Many early career researchers (ECRs) therefore actively seek this type of collaboration through choice or necessity, for professional ... -
Coastal restoration success via emergent trait-mimicry is context dependent
(Peer reviewed; Journal article, 2021)Coastal ecosystems provide vital ecosystem functions and services, but have been rapidly degrading due to human impacts. Restoration is increasingly considered key to reversing these losses, but is often unsuccessful. ... -
Cold-tolerant traits that favour northwards movement and establishment of Mediterranean and Ponto-Caspian alien aquatic invertebrates
(Peer reviewed; Journal article, 2022)Over recent decades, many Mediterranean and Ponto-Caspian aquatic invertebrate species have dispersed northwards and established as non-native species in colder regions. We hypothesized that these species have cold-tolerant ... -
