At Milne Fiord on Ellesmere Island we wish to core sediments at the bottom of the fjord. These cores will be used to reconstruct past environments to help put recent changes in to a longer context. 2-5 cores will be taken annually over the next several years. We are also hoping to add sediment traps too our long-term mooring in the fiord. We will continue to use our newly purchased remotely operated vehicle (ROV) to explore under-ice environments. This ROV has a video camera, an imaging sonar and can take samples using a gripper arm. In 2017 we discovered a benthic ecosystem (scallops, corals, sea stars, worms) living inside the Milne Ice Shelf (https://wirl.carleton.ca/calving-2020/#life-inside-milne-ice-shelf). We had thought that this habitat was destroyed during the calving of the Milne Ice Shelf in 2020 but now we are not certain. We would like permission to sample some organisms IF we find this ecosystem in new locations in the fiord AND the organisms are abundant (we will sample only less than 5% of the population and take photos of the rest). In particular, we wish to take up to 40 scallops to analyze their shells to find their age and environmental history.
