Providing essential data about the biogeochemistry and discharge of the largest Arctic rivers

Massive northern rivers transport huge quantities of water and constituents from the continents to the Arctic Ocean. Changes in Arctic river discharge and chemistry reflect changes occurring on land and lead to changes in the chemistry, biology, and circulation of the receiving coastal and ocean waters.

We want you to use ArcticGRO Data

Since 2003, ArcticGRO has been sampling the Arctic’s six largest rivers multiple times per year.  We also provide ready access to regularly updated daily discharge data for ArcticGRO rivers. The rotating figures below show daily discharge for each ArcticGRO river since beginning of the project, and indicate the dates that ArcticGRO sampled each river.

New @IOPPublishing study: Watershed slope can serve as most important variable for estimating spring/summer DOC and DON concentrations, and to a lesser degree nitrate, from drainage areas where field data are lacking. Lead Author: CT Connolly. Read more:

Changes in hydrology associated with landscape alteration that can result in deeper flow paths or longer residence times will likely lead to a greater proportion of aged carbon in riverine exports. Lead Author: @waterbarnes. Read more: #ArcticScience

According to the @NOAA-led #ArcticReportCard, in 2018 summer/autumn discharge (July 15-September 30) for the eight largest Arctic rivers was 20% greater than the 1980-89 reference period. Read more: @MaxHolmes @fromzhigansk #AGU18 #ArcticScience
