Programa igor pro7/25/2023 ![]() ![]() ![]() They are particularly interested at the processes coupling the terrestrial and aquatic compartments of watersheds, asking questions such as 'how do increased melting of glaciers impact lake biogeochemistry and ecology?' Igor and his team look at the impact warming glaciers have on sediment, and how the increase in sediment impacts the foodwebs of organisms in the Arctic. For this research, Igor has teamed up with a group consisting of hydrologists, molecular ecologists and glacier specialists. Igor’s research aims to identify and quantify the impacts of a changing climate on Arctic lakes and watersheds to determine how sensitive (or resilient) these ecosystems might be to climate change. Some of the impacts of this changing climate have been well documented, such as the rapidly declining summer sea-ice cover. The Arctic is warming at a faster rate than any other region around the globe.
