Seasonal variation of the transport of black carbon aerosol from the Asian continent to the Arctic during the ARCTAS aircraft campaign [PDF]

, 2011
Extensive measurements of black carbon (BC) aerosol were conducted in and near the North American Arctic during the Arctic Research of the Composition of the Troposphere from Aircraft and Satellites (ARCTAS) aircraft campaign in April and June-July 2008.

Mechanisms of De‐icing by Surface Rayleigh and Plate Lamb Acoustic Waves

Advanced Engineering Materials, EarlyView.
Ice accretion impacts daily life, renewable energy generation, maintenance, and security in industries and aeronautics. Acoustic waves (AW) are a promising method for ice removal, although de‐icing mechanisms require further investigation to optimize energy efficiency.

Arctic amplification metrics [PDF]

arXiv, 2018
One of the defining features of both recent and historical cases of global climate change is Arctic Amplification (AA). This is the more rapid change in the surface air temperature (SAT) in the Arctic compared to some wider reference region, such as the Northern Hemisphere (NH) mean.

Direct determination of the air‐sea CO2 gas transfer velocity in Arctic sea ice regions

, 2017
The Arctic Ocean is an important sink for atmospheric CO2. The impact of decreasing sea ice extent and expanding marginal ice zones on Arctic air‐sea CO2 exchange depends on the rate of gas transfer in the presence of sea ice.

Near-inertial Pollard Waves Modeling the Arctic Halocline [PDF]

arXiv
We present an explicit exact solution to the governing equations describing the vertical structure of the Arctic Ocean region centered around the North Pole. The solution describes a stratified water column with three constant-density regions: a motionless bottom layer, a top layer with uniform velocity and a middle layer - the halocline - described by
