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 ... -
A review of air-ice chemical and physical interactions (AICI): Liquids, quasi-liquids, and solids in snow
(Peer reviewed; Journal article, 2014-02-12)Snow in the environment acts as a host to rich chemistry and provides a matrix for physical exchange of contaminants within the ecosystem. The goal of this review is to summarise the current state of knowledge of physical ... -
A revised ocean glider concept to realize Stommel's vision and supplement Argo floats
(Journal article; Peer reviewed, 2020-02)This paper revisits Stommel's vision for a global glider network and the Argo design specification. A concept of floats with wings, so-called slow underwater gliders, is explored. An analysis of the energy or power consumption ... -
Rise and fall of sea ice production in the Arctic Ocean’s ice factories
(Journal article; Peer reviewed, 2022)The volume, extent and age of Arctic sea ice is in decline, yet winter sea ice production appears to have been increasing, despite Arctic warming being most intense during winter. Previous work suggests that further warming ... -
Riverine impact on future projections of marine primary production and carbon uptake
(Journal article; Peer reviewed, 2023)Riverine transport of nutrients and carbon from inland waters to the coastal and finally the open ocean alters marine primary production (PP) and carbon (C) uptake regionally and globally. So far, this process has not been ... -
Rogue waves: Results of the ExWaMar project
(Journal article; Peer reviewed, 2024)Rogue waves, also known as freak waves, have received much attention in the scientific community as well as in media and the marine industry in the past two decades. Forecasts of extreme weather events have always been ... -
The role of air–sea coupling on November–April intraseasonal rainfall variability over the South Pacific
(Journal article; Peer reviewed, 2022)We investigate the impact of resolving air-sea interaction on the simulation of the intraseasonal rainfall variability over the South Pacific using the ECHAM5 atmospheric general circulation model coupled with the ... -
The Role of Atlantic Heat Transport in Future Arctic Winter Sea Ice Loss
(Peer reviewed; Journal article, 2019-05-14)During recent decades Arctic sea ice variability and retreat during winter have largely been a result of variable ocean heat transport (OHT). Here we use the Community Earth System Model (CESM) large ensemble simulation ... -
Role of atmosphere-ocean interactions in supermodeling the tropical Pacific climate
(Peer reviewed; Journal article, 2017-12-29)The supermodel strategy interactively combines several models to outperform the individual models comprising it. A key advantage of the approach is that nonlinear improvements can be achieved, in contrast to the linear ... -
Role of Atmosphere-ocean-ice Interaction in the Linkage between December Bering Sea Ice and Subsequent February Surface Air Temperature Over North America
(Journal article; Peer reviewed, 2023)This study revealed that the interannual variations of December Bering Sea ice and subsequent February surface air temperature (SAT) over North America are significantly correlated during 2000/01-2020/21, which is not the ... -
The role of land and ocean evaporation on the variability of precipitation in the Yangtze River valley
(Peer reviewed; Journal article, 2019-06-04)The Yangtze River valley (YRV) experiences large intraseasonal and interannual precipitation variability, which is mainly due to East Asian monsoon influence. The East Asian monsoon is caused by interaction of many processes ... -
The Role of Mid-latitude Westerly Jet in the Impacts of November Ural Blocking on Early-Winter Warmer Arctic-Colder Eurasia Pattern
(Journal article; Peer reviewed, 2022)Based on statistical analysis using observations and idealized model simulations, previous studies have revealed the potential response of early-winter atmospheric circulation and temperature anomalies to November Ural ... -
The Role of Ocean Heat Content on the Madden–Julian Oscillation
(Doctoral thesis, 2024-03-19)Det overordnede målet med denne avhandlingen er å forstå hvilken rolle varmeinnholdet i den øvre delen av havet og havdynamikken rundt ekvator spiller for Madden-Julian svingningen (MJO). Mens havets respons til atmosfæren ... -
The role of Rossby waves in polar weather and climate
(Journal article; Peer reviewed, 2023)Recent Arctic warming has fuelled interest in the weather and climate of the polar regions and how this interacts with lower latitudes. Several interesting theories of polar-midlatitude linkages involve Rossby wave propagation ... -
The role of sublimation as a driver of climate signals in the water isotope content of surface snow: Laboratory and field experimental results
(Journal article; Peer reviewed, 2021)Ice core water isotope records from Greenland and Antarctica are a valuable proxy for paleoclimate reconstruction, yet the processes influencing the climate signal stored in the isotopic composition of the snow are being ... -
The role of the sea surface temperature in the atmospheric seasonal cycle of the equatorial Atlantic
(Journal article; Peer reviewed, 2018)We investigate the role of sea surface temperature (SST) and land surface temperature (LST) in driving the seasonal cycle of the atmosphere (surface winds and precipitation) in the tropical Atlantic. For this we compare ... -
The role of the Southern Ocean in past global biogeochemical cycling
(Doctoral thesis, 2020-04-27)This thesis describes several recent advances on the role of the Southern Ocean in past global biogeochemical cycling. We focus on the ocean of the Last Glacial Maximum (LGM) and the Pleistocene epoch and apply proxies of ... -
