Flux of nutrients from Russian rivers to the Arctic Ocean: Can we establish a baseline against which to judge future changes? [PDF]

open access: yes, 2000
Climate models predict significant warming in the Arctic in the 21st century, which will impact the functioning of terrestrial and aquatic ecosystems as well as alter land‐ocean interactions in the Arctic.

Bayesian Inference of Spatio-Temporal Changes of Arctic Sea Ice [PDF]

open access: yesarXiv, 2020
Arctic sea ice extent has drawn increasing interest and alarm from geoscientists, owing to its rapid decline. In this article, we propose a Bayesian spatio-temporal hierarchical statistical model for binary Arctic sea ice data over two decades, where a latent dynamic spatio-temporal Gaussian process is used to model the data-dependence through a logit ...

Arctic Sea Ice State Estimation From Thermodynamic PDE Model [PDF]

open access: yesarXiv, 2019
Recent rapid loss of the Arctic sea ice motivates the study of the Arctic sea ice thickness. Global climate model that describes the ice's thickness evolution requires an accurate spatial temperature profile of the Arctic sea ice. However, measuring the complete temperature profile is not feasible within and throughout the Arctic icecap.

Optimal Combination of Arctic Sea Ice Extent Measures: A Dynamic Factor Modeling Approach [PDF]

open access: yesarXiv, 2020
The diminishing extent of Arctic sea ice is a key indicator of climate change as well as an accelerant for future global warming. Since 1978, Arctic sea ice has been measured using satellite-based microwave sensing; however, different measures of Arctic sea ice extent have been made available based on differing algorithmic transformations of the raw ...

Researchers explore Arctic freshwater\u27s role in ocean circulation [PDF]

open access: yes, 2000
A critical, but insufficiently understood, component of global change is the influence of Arctic freshwater input on water mass exchange between the Arctic Ocean and Atlantic and Pacific Oceans.

Probability Assessments of an Ice-Free Arctic: Comparing Statistical and Climate Model Projections [PDF]

open access: yesarXiv, 2019
The downward trend in the amount of Arctic sea ice has a wide range of environmental and economic consequences including important effects on the pace and intensity of global climate change. Based on several decades of satellite data, we provide statistical forecasts of Arctic sea ice extent during the rest of this century. The best fitting statistical

Arctic system on trajectory to new state [PDF]

open access: yes, 2005
The Arctic system is moving toward a new state that falls outside the envelope of glacial-interglacial fluctuations that prevailed during recent Earth history.

Effects of resource availability and interspecific interactions on Arctic and red foxes' winter use of ungulate carrion in the Fennoscandian low‐Arctic tundra

open access: yesEcology and Evolution
In the Arctic tundra, predators face recurrent periods of food scarcity and often turn to ungulate carcasses as an alternative food source. As important and localized resource patches, carrion promotes co‐occurrence of different individuals, and its use ...

Inoculation of seed with strains of nitrogen-fixing bacteria (exampled by oats and millet) [PDF]

open access: yesBIO Web of Conferences
As a result of the conducted researches the expediency and effectiveness of pre-sowing inoculation of seeds of field crops with strains of nitrogen-fixing bacteria has been proved, which allows to increase fodder productivity of oat and pearl millet ...

Bacterial Diversity and Composition in the Internal Organs of Taiga Bean Goose, Greater White-Fronted Goose and Willow Ptarmigan as a New Tools in the Arctic Biomonitoring System

open access: yesDiversity
Birds, fish, and marine mammals consumed by indigenous people are included in Arctic biomonitoring. However, there are still many gaps in the data on the microbiota associated with these animals.
