All organizations to which the IRS grants 501(c) tax-exempt status must yearly disclose both their revenues (including sources) and their expenses via their tax returns, which they file via Form 990.  Those are available for public review.  You can probably find them online without Charles' help.  I'm pretty sure that the Alaska Center receives no federal, state or local government support.  I was Executive Director of the predecessor organizations, Alaska Conservation Alliance and Alaska Conservation Voters from autumn 2001- autumn 2005, during which time we neither applied for nor received any government funding.  I suspect the same is true today, but confirm that for yourself through an online search.
