As global warming has continued to affect the planet’s biosphere, the future of vital organisms in the most vulnerable ecosystems has become less certain. The Canadian Arctic, one of the most susceptible regions to climate change, has experienced hundreds of primary and secondary populations becoming extinct or endangered as a result of warming temperatures and depleting sea ice. This article examines the results of two different investigations into the population density of ringed seals, Phoca (Pusa) hispida, an essential organism in the Arctic marine food web, as related to sea ice concentration. Each set of results was aligned with daily Arctic sea ice
concentration satellite images from the National Snow and Ice Data Center to determine the credibility and accuracy of each article’s findings. It is concluded that the articles share similar results with each other and with the NSIDC, though large lapses in time and restrictive season-based methodology prevent concrete conclusions to be made regarding reliability. These results provide a further outlook on the importance of source reliability and relevance.
