The National Academies are looking for people to aid in setting research priorities for the next 20 years.
Questionnaire Questionnaire on Emerging Research Questions in the Arctic
Background Project: Emerging Research Questions in the Arctic
Relevant blog post Emerging Research Questions in the Arctic - Arctic Sea Ice Some suggestions in the comments there already might get your ideas going. (This site can get pretty technical pretty quickly if you're not used to that level of discussion. There are a couple of active researchers as frequent commenters.)
I know some members have an interest in the Arctic. There's no way of knowing how many readers have an interest or relevant expertise. So it's here for all of you.
And don't think too long or too hard, you have to get your skates on. Submissions close next Friday, August 23rd.
