Two sediment piston cores were recovered from the Chukchi-Alaskan (05JPC) and Canadian Beaufort (02PC) margins to investigate grain-size, geochemical and mineralogical compositions. This allowed the reconstruction of changes in detrital sediment provenance and transport...

Hydrobelts divide the global landmasses into eight hydrological regions with resolution of 0.5°, based primarily on the annual average temperature (T) and runoff (q). The interbelt differences were maximised and intrabelt variability minimise. These hydrobelts are decom...

Narrowing uncertainties about carbon cycling is important in the Arctic where rapid environmental changes contribute to enhanced mobilization of carbon. Here we quantify soil organic carbon (SOC) contents of permafrost soils along the Yukon Coastal Plain and determine t...

The Arctic Ocean is a region particularly prone to on-going ocean acidification (OA) and climate-driven changes. The influence of these changes on Arctic phytoplankton assemblages, however, remains poorly understood. In order to understand how OA and enhanced irradiance...

The last interglacial period (about 125,000 years ago) is thought to have been at least as warm as the present climate (Kukla et al., 2002, doi:10.1006/qres.2001.2316). Owing to changes in the Earth's orbit around the Sun, it is thought that insolation in the Northern H...

Abundances (percent cover, counts or biomass) of rocky mid-intertidal macro-species measured through a multi-factorial in situ experiment of 14 months in 2012-2013 in Sainte-Flavie, Québec, Canada (48°37'42.5″ N, 68°11'55.7″ W).Using 0.25-m² plots, we ran an in situ one...

In order to allow full comparability with other ocean acidification data sets, the R package seacarb (Gattuso et al, 2019) was used to compute a complete and consistent set of carbonate system variables, as described by Nisumaa et al. (2010). In this dataset the origina...

The potential interactive effects of iron (Fe) limitation and Ocean Acidification in the Southern Ocean (SO) are largely unknown. Here we present results of a long-term incubation experiment investigating the combined effects of CO2 and Fe availability on natural phytop...

Palaeomagnetic investigation of three sediment cores from the Chukchi and Beaufort Sea margins was performed to better constrain the regional chronostratigraphy and to gain insights into sediment magnetic properties at the North American Arctic margin during the Holocen...

The dataset compiles survival data, muscle mineral content as proxy for nutritional quality and the taste, smell, texture, and appearance as proxies for organoleptic quality of the northern shrimp Pandalus borealis after an exposure of 30 days under laboratory condition...
