Constraining the oceanic uptake and fluxes of greenhouse gases by building an ocean network of certified stations: The ocean component of the Integrated Carbon Observation System, ICOS-Oceans
(Peer reviewed; Journal article, 2019)The European Research Infrastructure Consortium “Integrated Carbon Observation System” (ICOS) aims at delivering high quality greenhouse gas (GHG) observations and derived data products (e.g., regional GHG-flux maps) for ... -
Constructive and experimental examination of reliability and robustness in dynamically stressed bolted joints
(Master thesis, 2018-12)Loosening and failure of bolts and nuts is, and has historically always been, a challenge for industries all over the world. This thesis examines the bolted connections of a local plough manufacturer (hereafter referred ... -
Continued warming, salinification and oxygenation of the Greenland Sea gyre
(Peer reviewed; Journal article, 2018-06-18)The Greenland Sea gyre is one of the few areas where the water column is ventilated through open ocean convection. This process brings both anthropogenic carbon and oxygen from the atmosphere and surface ocean into the ... -
Continuous monitoring of the isotopic composition of surface water vapor at Lhasa, southern Tibetan Plateau
(Journal article; Peer reviewed, 2021)The stable isotopes (δ18O and δD) of water vapor are used to characterize continuous variations in large-scale and boundary-layer atmospheric processes. We presented continuous measurements of δ18O in surface water vapor ... -
Contrasting responses of the ocean’s oxygen minimum zones to artificial re-oxygenation
(Journal article; Peer reviewed, 2023)Studies assessing potential measures to counteract the marine deoxygenation attributed to anthropogenic activities have been conducted in a few coastal environments and at regional scale, but not yet on a global scale. One ... -
Contributors to linkage between Arctic warming and East Asian winter climate
(Journal article; Peer reviewed, 2021)Previous modelling and observational studies have shown discrepancies in the interannual relationship of winter surface air temperature (SAT) between Arctic and East Asia, stimulating the debate about whether Arctic change ... -
Control of Barents Sea wintertime cyclone variability by large-scale atmospheric flow
(Journal article; Peer reviewed, 2020)Extratropical cyclones transport heat and moisture into the Arctic, which can promote surface warming and sea ice melt. We investigate wintertime cyclone variability in the Barents Sea region to understand what controls ... -
Convective chimneys and plumes in the Northern Greenland Sea
(Geophysical Monograph Series;30, Chapter, 2005)In the Boreas Basin in the northern Greenland Sea, convection has been observed to be localized as narrow structures - chimneys - in which the water masses may be homogeneous from the surface through great depths. An ... -
Cool Roofs in Smart Cities: Implications for Urban Heat Island Mitigation and Building Energy Efficiency in Different Climate Zones
(Master thesis, 2018-10-05)As climate change contributes to elevate urban temperatures, undesirable consequences like increased energy consumption, reduced air and water quality and elevated levels of thermal stress for the population continue to ... -
Coralline algal Barium as indicator for 20th century northwestern North Atlantic surface ocean freshwater variability
(Peer reviewed; Journal article, 2013)During the past decades climate and freshwater dynamics in the northwestern North Atlantic have undergone major changes. Large-scale freshening episodes, related to polar freshwater pulses, have had a strong influence on ... -
Correcting the impact of the isotope composition on the mixing ratio dependency of water vapour isotope measurements with cavity ring-down spectrometers
(Journal article; Peer reviewed, 2020)Recent advances in laser spectroscopy enable high-frequency in situ measurements of the isotope composition of water vapour. At low water vapour mixing ratios, however, the measured stable water isotope composition can be ... -
Correction to “Sea ice velocity in the Fram Strait monitored by moored instruments”

The COTUR project: remote sensing of offshore turbulence for wind energy application
(Journal article; Peer reviewed, 2021)The paper presents the measurement strategy and data set collected during the COTUR (COherence of TURbulence with lidars) campaign. This field experiment took place from February 2019 to April 2020 on the southwestern coast ... -
Coupled Al-Si geochemistry in an ocean general circulation model: A tool for the validation of oceanic dust deposition fields?
(Peer reviewed; Journal article, 2003-03-19)We introduced the marine cycle of Al into a geochemical ocean general circulation model in order to assess the potential of modeled surface ocean dissolved Al as a tracer for dust input to the world ocean. The geochemical ... -
Coupled atmosphere-ice-ocean dynamics in Dansgaard-Oeschger events
(Peer reviewed; Journal article, 2018-11-10)The Dansgaard-Oeschger events of the last ice age are among the best studied abrupt climate changes, yet a comprehensive explanation is still lacking. They are most pronounced in the North Atlantic, where they manifest as ... -
Coupled atmosphere–ocean observations of a cold-air outbreak and its impact on the Iceland Sea
(Journal article; Peer reviewed, 2023)Marine cold-air outbreaks (CAOs) are vigorous equatorward excursions of cold air over the ocean, responsible for the majority of wintertime oceanic heat loss from the subpolar seas of the North Atlantic. However, the impact ... -
Coupled stratosphere-troposphere-Atlantic multidecadal oscillation and its importance for near-future climate projection
(Journal article; Peer reviewed, 2022)Northern Hemisphere (NH) climate has experienced various coherent wintertime multidecadal climate trends in stratosphere, troposphere, ocean, and cryosphere. However, the overall mechanistic framework linking these trends ... -
Critical vulnerabilities of marine and sea ice–based ecosystems in the high Arctic
(Peer reviewed; Journal article, 2010-12-01)The objectives of this paper are to summarise: (1) observed 20th-century and projected 21st-century changes in key components of the Arctic climate system and (2) probable impacts on the Arctic marine environment, with ... -
Current shear and turbulence during a near-inertial wave
(Journal article; Peer reviewed, 2023-04-11)Surface currents and turbulent mixing were observed during a near-inertial wave (NIW) using an accousting doppler current profiler (ADCP) and satellite-tracked drifters. Drifter trajectories sampled at three depth levels ... -
