TL;DR: Synthesis of river-monitoring data reveals that the average annual discharge of fresh water from the six largest Eurasian rivers to the Arctic Ocean increased by 7% from 1936 to 1999, a large-scale change in freshwater flux.

TL;DR: In this paper, the authors review features of macroalgal blooms pointed out in recent literature and summarize work done in the Waquoit Bay Land Margin Ecosystems Research project which suggests that nutrient loads, water residence times, presence of fringing salt marshes, and grazing affect macroalgae blooms.

TL;DR: In this paper, stable isotope data from a series of estuaries receiving nitrogen loads from 2 to 467 kg N ha -1 yr -1 from the Waquoit Bay watershed, Cape Cod, Massachusetts, indicate that producer and consumer 15 N to 14 N ratios record increases in wastewater nitrogen inputs.

TL;DR: A review of recent studies investigating linkages between permafrost dynamics and river biogeochemistry in the Arctic is presented in this article, including consideration of likely impacts that warming-induced changes in permfrost may be having (or will have in the future) on the delivery of organic matter, inorganic nutrients, and major ions to the Arctic Ocean.

TL;DR: In this article, seasonal and annual constituent fluxes have been determined using consistent sampling and analytical methods at the pan-Arctic scale and consequently provide the best available estimates for constituent flux from land to the Arctic Ocean and surrounding seas.
