It became apparent at an early stage that soliciting articles for what was originally a special section on the Arctic alone was not going to produce sufficient material.

Consequently, we have four articles and only one involves the Arctic. Furthermore, the three non-Arctic papers deal with unconventional resource plays for gas and heavy oil production.
