Response to comments on “Saturation of the Southern Ocean CO2 sink due to recent climate change”
Read more of: Response to comments on “Saturation of the Southern Ocean CO2 sink due to recent climate change”We estimated a weakening of the Southern Ocean carbon dioxide (CO2) sink since 1981 relative to the trend expected from the large increase in atmospheric CO2. We agree with Law […]

Emerging pattern of global change in the upper atmosphere and ionosphere
Read more of: Emerging pattern of global change in the upper atmosphere and ionosphereIn the upper atmosphere, greenhouse gases produce a cooling effect, instead of a warming effect. Increases in greenhouse gas concentrations are expected to induce substantial changes in the mesosphere, thermosphere, […]

Dust-climate couplings over the past 800,000 years from the EPICA Dome C ice core
Read more of: Dust-climate couplings over the past 800,000 years from the EPICA Dome C ice coreDust can affect the radiative balance of the atmosphere by absorbing or reflecting incoming solar radiation(1); it can also be a source of micronutrients, such as iron, to the ocean(2). […]

Structure of intertidal and subtidal assemblages in Arctic vs temperate boulder shores
Read more of: Structure of intertidal and subtidal assemblages in Arctic vs temperate boulder shoresSeveral studies suggest that assemblages in intertidal zones that experience frequent physical extremes (e.g. wave-impacts) should be highly dependent on the regional input of propagules. Therefore with higher disturbance in […]

Marine cold-air outbreaks in the future: an assessment of IPCC AR4 model results for the Northern Hemisphere
Read more of: Marine cold-air outbreaks in the future: an assessment of IPCC AR4 model results for the Northern HemisphereFor many locations around the globe some of the most severe weather is associated with outbreaks of cold air over relatively warm oceans, referred to here as marine cold-air outbreaks […]

Glacier-bed characteristics of midtre Lovénbreen, Svalbard, from high-resolution seismic and radar surveying
Read more of: Glacier-bed characteristics of midtre Lovénbreen, Svalbard, from high-resolution seismic and radar surveyingWe conducted a seismic and radar survey of the central part of midtre Lovenbreen, a small, polythermal valley glacier in Svalbard. We determined the physical properties of the material beneath […]

Seasonal variation in the white muscle biochemical composition of deep-sea macrourids in the North-east Atlantic
Read more of: Seasonal variation in the white muscle biochemical composition of deep-sea macrourids in the North-east AtlanticThe foremost temporal signal to the deep benthos, where temperature and light conditions are relatively constant, is a seasonal pulse of organic carbon sinking from the photic layer. In the […]

A new technique for periodic bait release at a deep-sea camera platform: first results from the Charlie-Gibbs Fracture Zone, Mid-Atlantic Ridge
Read more of: A new technique for periodic bait release at a deep-sea camera platform: first results from the Charlie-Gibbs Fracture Zone, Mid-Atlantic RidgeDirect time-series observations of deep-sea biological activity are largely restricted to passive observations of benthic epifauna using unbaited time-lapse camera systems. However, highly mobile fauna such as scavenging fish are […]

An improved continuous flow analysis system for high-resolution field measurements on ice cores
Read more of: An improved continuous flow analysis system for high-resolution field measurements on ice coresContinuous flow analysis (CFA) is a well-established method to obtain information about impurity contents in ice cores as indicators of past changes in the climate system. A section of an […]

Stratospheric influence on circulation changes in Southern Hemisphere troposphere in coupled climate models
Read more of: Stratospheric influence on circulation changes in Southern Hemisphere troposphere in coupled climate modelsThe recent intensification of the circumpolar circulation in the SH troposphere in summer and autumn has been attributed to external forcing such as stratospheric ozone depletion and greenhouse gas (GHG) […]

Southern Ocean deep-sea biodiversity: sampling strategies and predicting responses to climate change
Read more of: Southern Ocean deep-sea biodiversity: sampling strategies and predicting responses to climate changeThe deep sea surrounds Antarctica and constitutes about 80%, of the Southern Ocean (SO) seabed. Scientific cruises (e.g. ANDEEP) reveal that SO abyssal life can be highly abundant, rich and […]
