Rivers integrate processes occurring throughout their watersheds and are therefore
sentinels of change across broad spatial scales. River chemistry also regulates ecosystem …

Permafrost is a crucial part of the Earth's cryosphere. These millennia-old frozen soils not
only are significant carbon reservoirs but also store a variety of chemicals. Accelerated …

Anthropogenic climate warming is amplified in the Arctic, impacting the Arctic carbon cycle
and its role in regulating climate and global biogeochemical cycles. In this Review, we …

Arctic rivers provide an integrated signature of the changing landscape and transmit signals
of change to the ocean. Here, we use a decade of particulate organic matter (POM) …

In contrast to good knowledge of export fluxes of carbon and metals from mainland to the
Arctic Ocean by large Arctic Rivers, information on mid-sized rivers is limited, which prevents …

Study area: We evaluated the Virgin, Verde, Salt, and Gila Rivers in the Lower Colorado
River Basin. The watersheds have extents in Arizona, Utah, New Mexico, US and Sonora …

Soil is one of the largest reservoirs and re-emission sources of mercury (Hg) on Earth's
surface. The accumulation and remobilization of Hg during pedogenesis affect how Hg is …

Coastal oceans, the transition zones between terrestrial and oceanic systems, are
susceptible to anthropogenic mercury (Hg) inputs and are regarded as critical dynamic …

Conclusion Our original Article reported widespread surface water declines across lake-rich
regions of the Arctic 1. Although Arctic surface water map** and trend detection are …

Abstract The Northeast Arctic cod (Gadus morhua) is the world's northernmost stock of
Atlantic cod and is of considerable ecological and economic importance. Northeast Arctic …
