CHARS has five science-related priorities, two of which you have mentioned. The first is resource development, baseline information. The second is climate change. The proportion of funding allotted to each will be determined by the CHARS management committee, which has 30 members from academia and northern institutions. The proportion will change every year—it's not fixed—so that the management committee has the ability to allocate different amounts.
