Journal ArticleDOI

Increasing river discharge to the Arctic Ocean

Bruce J. Peterson, +7 more
- 13 Dec 2002 - 
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.
Journal ArticleDOI

A simple and precise method for measuring ammonium in marine and freshwater ecosystems

Robert M. Holmes, +4 more
- 01 Oct 1999 - 
TL;DR: A fluorometric method is presented that gives precise measurements of ammonium over a wide range of concentrations and salinities emphasizing submicromolar levels and not only solves analytical problems but also substantially simplifies sample collection and preservation.
Journal ArticleDOI

Seasonal and Annual Fluxes of Nutrients and Organic Matter from Large Rivers to the Arctic Ocean and Surrounding Seas

Robert M. Holmes, +13 more
- 01 Mar 2012 - 
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.
Journal ArticleDOI

Natural abundance-level measurement of the nitrogen isotopic composition of oceanic nitrate: an adaptation of the ammonia diffusion method

Daniel M. Sigman, +5 more
- 01 Jul 1997 - 
TL;DR: In this article, the authors adapted the "ammonia diffusion" method of nitrate extraction for natural-abundance level nitrogen isotopic measurement of oceanic nitrate, and characterized the blanks inherent in this method and designed a protocol to minimize them.
Journal ArticleDOI

Flux and age of dissolved organic carbon exported to the Arctic Ocean: A carbon isotopic study of the five largest arctic rivers

Peter A. Raymond, +8 more
- 01 Dec 2007 - 
TL;DR: In this article, the export and Δ 14 C-age of dissolved organic carbon (DOC) was determined for the Yenisey, Lena, Ob', Mackenzie, and Yukon rivers for 2004-2005.
