Response of Arctic Ocean stratification to changing river runoff in a column model
(Peer reviewed; Journal article, 2015-04-07)A one-dimensional model of the atmosphere-ice-ocean column is used to study the effects of changing river runoff to the Arctic Ocean. River runoff is the largest contributor of freshwater to the Arctic and is expected to ... -
The Response of Heterotrophic Prokaryote and Viral Communities to Labile Organic Carbon Inputs Is Controlled by the Predator Food Chain Structure
(Peer reviewed; Journal article, 2017-08-23)Factors controlling the community composition of marine heterotrophic prokaryotes include organic-C, mineral nutrients, predation, and viral lysis. Two mesocosm experiments, performed at an Arctic location and bottom-up ... -
Response of Methanogens in Arctic Sediments to Temperature and Methanogenic Substrate Availability
(Peer reviewed; Journal article, 2015-06-17)Although cold environments are major contributors to global biogeochemical cycles, comparatively little is known about their microbial community function, structure, and limits of activity. In this study a microcosm based ... -
The response of permafrost and high latitude ecosystems under large scale stratospheric aerosol injection and its termination
(Peer reviewed; Journal article, 2019-04-15)Climate engineering arises as one of the potential methods that could contribute to meeting the 1.5oC global warming target agreed under the Paris Agreement. We examine how permafrost and high latitude vegetation respond ... -
Response to comment on “Dispersal limitations matter for microbial morphospecies”
(Peer reviewed; Journal article, 2007)Pither argues that the relationship we found between regional species-richness maxima and modal lake-pH is expected because both values are constrained by the regional pH range and therefore cannot be interpreted as a ... -
Response: Demography affects spawning location in Northeast Arctic cod, but what affects demography?
(Journal article, 2015-06-19) -
Responses of Free-Living Planktonic Bacterial Communities to Experimental Acidification and Warming
(Journal article; Peer reviewed, 2023)Climate change driven by human activities encompasses the increase in atmospheric CO2 concentration and sea-surface temperature. Little is known regarding the synergistic effects of these phenomena on bacterial communities ... -
Responses of tundra plants to experimental warming : meta-analysis of the international tundra experiment
(Peer reviewed; Journal article, 1999)The International Tundra Experiment (ITEX) is a collaborative, multisite experiment using a common temperature manipulation to examine variability in species response across climatic and geographic gradients of tundra ... -
Restricted maximum-likelihood method for learning latent variance components in gene expression data with known and unknown confounders
(Journal article; Peer reviewed, 2022)Random effects models are popular statistical models for detecting and correcting spurious sample correlations due to hidden confounders in genome-wide gene expression data. In applications where some confounding factors ... -
Results from the EPICAL-2 ultra-high granularity electromagnetic calorimeter prototype
(Journal article; Peer reviewed, 2023)A prototype of a new type of calorimeter has been designed and constructed, based on a silicon–tungsten sampling design using pixel sensors with digital readout. It makes use of the ALPIDE sensor developed for the ALICE ... -
Results from the intercalibration of optical low light calibration sources 2011
(Peer reviewed; Journal article, 2012-05-03)Following the 38th Annual European Meeting on Atmospheric Studies by Optical Methods in Siuntio in Finland, an intercalibration workshop for optical low light calibration sources was held in Sodankylä, Finland. The main ... -
Results of the Electron Drift Instrument on Cluster
(Journal article; Peer reviewed, 2021)The electron drift instrument (EDI) on Cluster pioneered a new method of measuring electric fields, using a beam of electrons to sample the drift velocity over a km-scale gyro orbit. The technique is especially well suited ... -
Resurrection of genus Phocanema Myers, 1959, as a genus independent from Pseudoterranova Mozgovoĭ, 1953, for nematode species (Anisakidae) parasitic in pinnipeds and cetaceans, respectively
(Journal article; Peer reviewed, 2023)Species of the genus Pseudoterranova, infect kogiid cetaceans and pinnipeds. However, there is mounting molecular evidence that those from cetaceans and pinnipeds are not congeneric. Here, we provide further evidence of ... -
Retention of Coastal Cod Eggs in a Fjord Caused by Interactions between Egg Buoyancy and Circulation Pattern
(Peer reviewed; Journal article, 2011-08-01)Norwegian coastal cod form a stationary population of Atlantic cod Gadus morhua consisting of several genetically separated subpopulations. A small-scale differentiation in marine populations with pelagic eggs and larvae ... -
Retrieval of snow properties from the Sentinel-3 Ocean and Land Colour Instrument
(Journal article, 2019)The Sentinel Application Platform (SNAP) architecture facilitates Earth Observation data processing. In this work, we present results from a new Snow Processor for SNAP. We also describe physical principles behind the ... -
Retrieval practice of a hierarchical principle structure in university introductory physics: Making stronger students
(Journal article; Peer reviewed, 2020)Introductory physics is taught to several hundred thousand university students every year. It is seen as especially difficult by many and the failure rate is often high. A relevant question is whether one can increase the ... -
Revealing the secrets of proteins: A triple-nuclear and multi-dimensional high-resolution NMR spectroscopy study
(Doctoral thesis, 2012-08-28)Nuclear magnetic resonance (NMR) spectroscopy is one of the major tools for studying the structure and dynamics of proteins in solution. The still ongoing development of new and improved pulse-sequences for multi-dimensional, ... -
Reversals in Temperature-Precipitation Correlations in the Northern Hemisphere Extratropics During the Holocene
(Journal article; Peer reviewed, 2022)Future precipitation levels remain uncertain because climate models have struggled to reproduce observed variations in temperature-precipitation correlations. Our analyses of Holocene proxy-based temperature-precipitation ... -
