Abstract The Atlantic Meridional Overturning Circulation (AMOC) is a key component of the
climate through its transport of heat in the North Atlantic Ocean. Decadal changes in the …

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

2 Chapter 2 assesses observed large-scale changes in climate system drivers, key climate
indicators and 3 principal modes of variability. Chapter 3 considers model performance and …

Microplastics are increasingly recognized as ubiquitous global contaminants, but questions
linger regarding their source, transport and fate. We document the widespread distribution of …

Warm water of subtropical origin flows northward in the Atlantic Ocean and transports heat to
high latitudes. This poleward heat transport has been implicated as one possible cause of …

The Pacific inflow to the Arctic traditionally brings heat in summer, melting sea ice; dense
waters in winter, refreshing the Arctic's cold halocline; and nutrients year‐round, supporting …

Dramatic environmental shifts are occuring throughout the Arctic from climate change, with
consequences for the cycling of mercury (Hg). This review summarizes the latest science on …

A temperature and salinity hydrographic profile climatology is assembled, evaluated for data
quality, and analyzed to assess changes of the Bering and Chukchi Sea continental shelves …

Poleward ocean heat transport is a key process in the earth system. We detail and review
the northward Atlantic Water (AW) flow, Arctic Ocean heat transport, and heat loss to the …

Abstract Changes in the Atlantic Meridional Overturning Circulation (AMOC) represent a
crucial component of Northern Hemisphere climate variability. In modelling studies decadal …
