This campaign took place in April 2015, with a focus on the characterization of ice clouds and pollutant levels, including black carbon, across the Arctic. The campaign was again a collaboration between NETCARE scientists and The Alfred Wegener Institute (AWI). Along with the POLAR 6, the...

From September 2014 to June 2015 NETCARE scientists conducted an intensive snow sampling campaign at Alert, Nunavut, Canada. Fresh snow samples were collected every few days and analyzed for black carbon, major ions, metals, elemental carbon, and organic carbon. Site Information:...

Ten NETCARE scientists were on board the Canadian Coast Guard Ship Amundsen, a research icebreaker, studying atmospheric and oceanic composition throughout the central Arctic in 2014. The cruise departed from Quebec City on July 8, entered Lancaster Sound on July 17, underwent a partial exchange...

In 2016 NETCARE scientists conducted two measurement campaigns at the Dr. Neil Trivett Global Atmosphere Watch Observatory (the “Alert Observatory”) on the northeastern tip of Ellesmere Island in the Canadian Arctic (latitude: 82.5163, longitude: -62.3085). The first campaign...

A large-scale aircraft campaign (on the German POLAR6 aircraft) took place in July 2014, based out of Resolute Bay, Nunavut, aimed to assess the different roles that oceanic input and long range transport from lower latitudes play in driving Arctic atmospheric composition. For five days in late...

Although the extent to which large-scale environmental change will affect birds that breed in arctic areas will vary among species, reduced reproductive success and population declines have been observed in long-distance migrants and species whose reproduction depends on non-climatic cues....

Monitoring of sea ice dynamics is of vital importance to our overall understanding of how the Arctic cryosphere is responding to changes in the Earth's climate. With the recent launch of the RADARSAT Constellation Mission (RCM) in 2019 and the continuing operation of the Sentinel-1 (S1) fleet,...

The objectives of the present long‐term study, spanning a 45 year period, were to 1) investigate the temporal trends of total mercury (THg; muscle and liver) and selenium (Se; liver) in ringed seals (Pusa hispida) from different regions of the Canadian Arctic; and 2) examine possible...

This dataset contains relative trends of annual and monthly regional maximum ocean wave heights in the Arctic, and data for three predictors derived from surface winds and sea ice concentration. It also contains estimates of historical (1979-2205) and future (2081-2100, RCP8.5 scenario) annual...

The delivery of perfluoroalkyl substances (PFAS) from snowpacks into Lake Hazen, located on Ellesmere Island (Nunavut, Canada) indicates that annual atmospheric deposition is a major source of PFAS that undergo complex cycling in the High Arctic. Perfluoroalkyl carboxylic acids (PFCA) in...
