Rare earth element data for Nunavik (Quebec, Canada): sediments, biofilm, algae, lichen, invertebrates, and various animal tissues of seals, birds and fishes [2017-2021]

The following sample groups are included in the dataset: algae (Alaria sp.), Arctic char (Salvelinus alpinus), Arctic cod (Boreogadus saida), Arctic hare (Lepus arcticus), Arctic sculpin (Myoxocephalus scorpioides), bearded seal (Erignathus barbatus), benthic invertebrates (Tricoptera, Ephemeroptera, Plecoptera), biofilm, Canada goose (Branta canadensis), common mussel (Mytilus edulis), reindeer lichen (Cladonia sp.), ringed seal (Pusa hispida), river sediments, rock ptarmigans (Lagopus muta), whitefish (Coregonus clupeaformis), willow ptarmigans (Lagopus lagopus).

For the animal specimen, different tissues were subsampled and includes (depending on species) muscle, bone, liver, kidney, blubber, and the digestive tract. The concentration data was processed as follows: NA where not analyzed or below detection limit; where digestion blanks were detected, they were subtracted from the sample values. Methods provided in detail in available publication.

Dataset also includes: collection data (location, date); specimen measurements data (mass, length, sex), and humidity content - when available. Concentration data in dry weight (ug/g, nmol/g).
