Impact of internal wave drag on Arctic sea ice
A parameterization of the impact of internal waves on momentum transfer at the sea-ice–ocean interface based on previous work by McPhee has been implemented in a sea-ice model for the […]

Drivers of interspecific spatial segregation in two closely-related seabird species at a Pan-Atlantic scale
Read more of: Drivers of interspecific spatial segregation in two closely-related seabird species at a Pan-Atlantic scaleAim: Ecologically similar species living in sympatry are expected to segregate to reduce the effects of competition where re-sources are limiting. Segregation from heterospecifics commonly occurs in space, but it […]

The role of ocean circulation and regolith removal in triggering the Mid-Pleistocene Transition: Insights from authigenic Nd isotopes
Read more of: The role of ocean circulation and regolith removal in triggering the Mid-Pleistocene Transition: Insights from authigenic Nd isotopesApproximately 1,250,000 to 700,000 years ago, the pacing of glacial-interglacial cycles changed from 41,000 years to ∼100,000 years, a shift known as the ‘Mid-Pleistocene Transition’ (MPT). The cause – or […]

Biogenic silver nanoparticles synthesized by microalgae: A comprehensive review of eco-friendly wound healing therapies
Read more of: Biogenic silver nanoparticles synthesized by microalgae: A comprehensive review of eco-friendly wound healing therapiesWounds are generally caused by an injury to the skin such as a cut or a puncture. They can be considered in two groups, acute and chronic wounds. Poor wound […]

Plastics counteract the ability of Antarctic krill to promote the blue carbon pathway in the deep ocean
Read more of: Plastics counteract the ability of Antarctic krill to promote the blue carbon pathway in the deep oceanThe Antarctic krill (Euphausia superba) play a critical role in promoting the so-called “blue carbon pathway” by producing a large amount of fast-sinking faecal pellets (FPs) which facilitate the transport […]

Laser ablation inductively coupled plasma mass spectrometry measurements for high-resolution chemical ice core analyses with a first application to an ice core from Skytrain Ice Rise (Antarctica)
Read more of: Laser ablation inductively coupled plasma mass spectrometry measurements for high-resolution chemical ice core analyses with a first application to an ice core from Skytrain Ice Rise (Antarctica)Conventional methods of inorganic impurity analysis do not provide high enough depth resolution for many scientific questions in ice core science. In this study, we present a setup of laser […]

Seasonal and Local Time Variation in the Observed Peak of the Meteor Altitude Distributions by Meteor Radars
Read more of: Seasonal and Local Time Variation in the Observed Peak of the Meteor Altitude Distributions by Meteor RadarsMeteoroids of sub-milligram sizes burn up high in the Earth’s atmosphere and cause streaks of plasma trails detectable by meteor radars. The altitude at which these trails, or meteors, form […]
