MOSAiC's Pan Arctic Water Isotope Network: Sea ice-ocean-atmosphere interactions observed with water vapor isotope measurements from land and an icebreaker
Abstract
One of the fundamental changes to the climate system has been the loss of sea ice across the northern high latitudes. A particularly critical response to this sea ice reduction is through its effect on ocean-atmosphere interactions. Evaporation is now possible from places and periods not possible in the past, and this has increased water vapor content around the Arctic. However, the response of ocean-atmosphere interactions to sea ice loss varies significantly over time and space. To help quantify these variations, we have established the AWIN (Arctic Water Isotope Network) that uses continuous water vapor isotope measurements (δD, δ18O, and d-excess) at seven land-based stations from Barrow, Alaska to Ny Alesund, Svalbard and one on board the Polarstern. With a network of sites rather than a single station, we gain the advantage of tracking water vapor (from source to sink) and how it varies simultaneously across the Arctic Basin.
