Anthropogenic mercury (Hg) emissions have driven marked increases in Arctic Hg levels,
which are now being impacted by regional warming, with uncertain ecological …

The areal extent, concentration and thickness of sea ice in the Arctic Ocean and adjacent
seas have strongly decreased during the recent decades, but cold, snow-rich winters have …

The ongoing decline of Arctic sea ice exposes the ocean to anomalous surface heat and
freshwater fluxes, resulting in positive buoyancy anomalies that can affect ocean circulation …

Analyses of 32 yr (1979–2010) of Arctic sea ice extents and areas derived from satellite
passive microwave radiometers are presented for the Northern Hemisphere as a whole and …

The recent Arctic winter sea ice retreat is most pronounced in the Barents Sea. Using
available observations of the Atlantic inflow to the Barents Sea and results from a regional …

In sharp contrast to the decreasing sea ice coverage of the Arctic, in the Antarctic the sea ice
cover has, on average, expanded since the late 1970s. More specifically, satellite passive …

At the close of the Fourth International Polar Year, we take stock of the ecological
consequences of recent climate change in the Arctic, focusing on effects at population …

The Arctic is a region in transformation. Warming in the region has been amplified, as
expected from ice‐albedo feedback effects, with the rate of warming observed to be∼ …

The loss of Arctic sea ice has emerged as a leading signal of global warming. This, together
with acknowledged impacts on other components of the Earth system, has led to the term …

The characteristics and benefits of ocean color merged data sets created using a semi-
analytical model and the normalized water-leaving radiance observations from the …
