Climate Change Impacts for the Arctic Ocean Tool (CIAO Tool)

Compared to past decades (before 1980), the Arctic Ocean and atmosphere are transitioning to a more dynamic state. Projections of ice-free Arctic Ocean summers by the mid-21st century may actually underestimate the rate of change. This project will develop and deliver an interactive, web-based planning tool, associated datasets and high-resolution maps as a way to present the results of CIAO—Climate Change Impacts for the Arctic Ocean—a related ACCASP project that will estimate indicators of climate change on a basin scale for the Arctic Ocean.

By providing the results of CIAO in a usable, accessible format, stakeholders and managers—particularly in Arctic locations—will be able to estimate the impacts of present (1970-1999) and future climate change (2014-2100) on ocean temperature, currents, salinity, light availability and other factors that are relevant to ecosystem dynamics and models, and the associated planning process for modelling the Arctic ecosystem Footnote 1 . The project will also provide technical documentation and training for fisheries management personnel, as well as peer-reviewed reports and papers to provide a solid science foundation.
