The Arctic Ocean is warming faster than any other ocean region and as it absorbs fossil fuel emissions, it is gradually acidifying. Arctic sea ice is declining by 10% per decade. This affects the availability of sea ice habitats for organisms from plankton to mammals and modifies the ocean environment. The magnitude of water flowing into and out of the Arctic via pathways with the Atlantic and Pacific oceans is changing. Thus Arctic ecosystems are being impacted by multiple concurrent stressors and must adapt.
It is crucial to evaluate the impact of these multiple stressors on the Arctic ecosystem. Often these questions are tackled by studies that focus on a specific ecosystem in one location and document the various components of the food chain. However the Arctic is diverse, with a wide range of environments and complex ecosystems. Thus, we require a new approach that can provide information on Arctic ecosystems from a pan-Arctic perspective over decadal timescales.
