Contrasting neurochemical and behavioral profiles reflects stress coping styles but not stress responsiveness in farmed gilthead seabream (Sparus aurata)
(Peer reviewed; Journal article, 2020)In fish, as well as in other vertebrates, contrasting suites of physiological and behavioral traits, or coping styles, are often shown in response to stressors. However, the magnitude of the response (i.e. stress responsiveness) ... -
Contrasting responses of DMS and DMSP to ocean acidification in Arctic waters
(Journal article; Peer reviewed, 2013)Increasing atmospheric CO2 is decreasing ocean pH most rapidly in colder regions such as the Arctic. As a component of the EPOCA (European Project on Ocean Acidification) pelagic mesocosm experiment off Spitzbergen in 2010, ... -
Contribution of organic carbon to the total specific surface area of soils with varying clay mineralogy
(Peer reviewed; Journal article, 2022)Soil specific surface area (SA) reflects the quantity and quality of the soil mineral and organic fractions. For soil samples that have similar clay mineral types, clay content and or organic carbon (OC) contents are good ... -
A contribution to the knowledge of charophytes in Myanmar; morphological and genetic identification and ecology notes
(Peer reviewed; Journal article, 2020)Information on the distribution and species composition of charophytes in Myanmar is scarce. Only a few studies on charophytes in ponds were conducted in Myanmar at the end of the nineteenth and first half of the twentieth ... -
Contributions of marine area-based management tools to the UN sustainable development goals
(Peer reviewed; Journal article, 2022)Area-Based Management Tools (ABMTs) are spatial instruments for conservation and managing different forms of ocean use. A multitude of ABMTs exists in marine areas within and beyond national jurisdiction, ranging from tools ... -
Controlling Factors of Microplastic Riverine Flux and Implications for Reliable Monitoring Strategy
(Peer reviewed; Journal article, 2021)A significant proportion of marine plastic debris and microplastics is assumed to be derived from river systems. In order to effectively manage plastic contamination of the marine environment, an accurate quantification ... -
Conversion of Filter Presses to Vacuum Filter Dryers at VEAS Arbitration Report
(NIVA-rapport;3916, Research report, 1998)NIVA represented by Mr. T. Damhaug has been appointed to act as arbitrator in the dispute between VEAS and DryVac in connection with a contract regarding conversion of three conventional filter presses to vacuum filter ... -
Coordinated Environmental Monitoring Programme (CEMP). Levels, trends and effects of hazardous substances in fjords and coastal waters - 2007
(NIVA-rapport;5694, Research report, 2008)This report is part of the Norwegian contribution to OSPAR’s Coordinated Environmental Monitoring Programme (CEMP). CEMP 2007 included the monitoring of contaminants in blue mussel (51), dogwhelk (9), cod (9) and flatfish ... -
Coping with a changing environment: The effects of early life stress
(Journal article; Peer reviewed, 2016)Ongoing rapid domestication of Atlantic salmon implies that individuals are subjected to evolutionarily novel stressors encountered under conditions of artificial rearing, requiring new levels and directions of flexibility ... -
Copper ecological risk assessment using DGT technique and PNEC: A case study in the Brazilian coast
(Peer reviewed; Journal article, 2021)Estuarine systems are vulnerable to metals stress, such as copper (Cu). Thus, the development of applicable tools to improve routine monitoring programs is increasingly necessary. In the present work a comprehensive ... -
Correcting for bias in freshwater total nitrogen concentrations obtained with a modified standard (NS4743) method
(NIVA-rapport;7538, Research report, 2020)Concentrations of total nitrogen (TotN) in freshwater monitoring programs were unreliable for a limited period, probably because of inadequate sample digestion when using a modified version of method NS 4743 (“method A”) ... -
Correcting Knowledge Base Assertions
(Chapter, 2020)The usefulness and usability of knowledge bases (KBs) is often limited by quality issues. One common issue is the presence of erroneous assertions, often caused by lexical or semantic confusion. We study the problem of ... -
Costs and benefits of automated high-frequency environmental monitoring – The case of lake water management
(Peer reviewed; Journal article, 2021)Freshwater lakes are dynamic ecosystems and provide multiple ecosystem services to humans. Sudden changes in lake environmental conditions such as cyanobacterial blooms can negatively impact lake usage. Automated high-frequency ... -
Country Case Study on Climate Change Impacts and Adaptation Assessment in Antigua and Barbuda Water Resources Management
(NIVA-rapport;3798, Research report, 1998)This Report is a summary of findings from a mission to Antigua & Barbuda August 12 - 16, 1997. The quality and quantity of fresh water resources in Antigua and Barbuda are particularly vulnerable to climate change. The ... -
Coupling Water Column and Sediment Biogeochemical Dynamics: Modeling Internal Phosphorus Loading, Climate Change Responses, and Mitigation Measures in Lake Vansjø, Norway
(Peer reviewed; Journal article, 2019)We expanded the existing one‐dimensional MyLake model by incorporating a vertically resolved sediment diagenesis module and developing a reaction network that seamlessly couples the water column and sediment biogeochemistry. ... -
Critical limits for surface water acidification in Norwegian critical loads calculation and Water Framework Directive classification
(NIVA-rapport;6741, Research report, 2014)The objective of this study was to compare the critical limits for surface water acidification used in the critical loads calculation under the UNECE Convention on Long-range Transboundary Air Pollution and the EU Water ... -
Critical load exceedance and damage to fish populations
(NIVA-rapport;2900, Research report, 1993)To examine the relationship between the critical load exceedance and the damage to fish, the data for fish damage and water chemistry for 1000 lakes in Norway was used to derive the probability of damage to fish populations ... -
