Exploring the links between Large Igneous Provinces and dramatic environmental impact

An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Review of antarctic landfast sea ice observations

open access: yesShui kexue jinzhan, 2013
Variations of Antarctic landfast sea ice are not only a direct indicator of Antarctic climate change at a local scale,but also an ideal parameter for climate model evaluation.

Polar‐low track prediction using machine‐learning methods

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
Machine‐learning models are developed to produce reliable and efficient forecasts of polar‐low (PL) trajectories 12 hours ahead. A temporal model (RLSTM) benefiting from the rolling‐forecast strategy, improves overall prediction accuracy and is suitable for quick experimentation, while a spatiotemporal model (PL‐UNet), incorporating both historical and

Estimating the distribution of demand for Antarctic krill (Euphauisa superba) from land-based predators at South Georgia

open access: yes, 2007
South Georgia is renowned for the abundance of Antarctic krill (Euphausia superba) and a range of krill predators. Variability in krill availability at a range of scales, and the consequences of this for predator-prey interactions, mean that quantifying ...

History of female Polish pioneers and expeditioners in polar regions [PDF]

open access: yesPolish Polar Research
In the paper, we present a gradual transition from domination of men to equal treatment for men and women during the several decades of Polish expeditions to scientific stations in the Arctic and the Antarctic.

How consistently do ensemble prediction systems represent the growth of atmospheric uncertainty?

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
Spread‐based diagnostics calculated for 12 ensemble prediction systems are compared to understand the consistency with which they represent atmospheric uncertainty growth. Good correlation between all these systems is found in the extratropics for a lead time range from 48 hr to between 96 hr and 192 hr.

The complete chloroplast genome of an Antarctic moss Syntrichia filaris (Müll.Hal.) R.H. Zander

open access: yesMitochondrial DNA. Part B. Resources, 2019
Syntrichia filaris is one of the common mosses in the northern maritime Antarctic. In this study, we determined the complete chloroplast genome of S.

Stratospheric and tropospheric seasonality and its implications for observation requirements in numerical weather prediction

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
Daily time series of zonal‐mean zonal wind (m·s−1) at 10 hPa and 60° N from 1950 to 2021 from the ERA5 reanalysis. This shows huge variability in some seasons and very little in others. We provide evidence that high‐level observations, radiosonde and satellite, are more important during the extended winter season with its very large variability ...

Photosynthetic responses of three common mosses from continental Antarctica

open access: yes, 2005
Predicting the effects of climate change on Antarctic terrestrial vegetation requires a better knowledge of the ecophysiology of common moss species. In this paper we provide a comprehensive matrix for photosynthesis and major environmental parameters ...
