Let me use this occasion for a quick review of her Wikipedia entry. I don't know anything about Crockford but her entry is the typical smear job written by some activist editor who is only concerned with presenting the subject in the worst possible light. This stuff and writing style has no place on a decent encyclopedia, and the persistence of these entries through the years is one of the reasons I'm fed up with Wikipedia.
Warning: irony ahead.
In the first line of the lede, Susan Crockford is introduced as "a Canadian contract scientist who runs a small business identifying bones and other items in scat of wildlife". (italics mine)
It's clear that the lady is just a contract scientist with a small business. We can picture her rummaging the scat of wildlife for "items", presumably keys or other small objects lost perhaps by serious scientists while doing their work.
In the "Early life and education" section, we're first told that she "gained her interest in the Arctic in elementary school" and that her scientific interest was stoked at age 11 when she received a dog for her birthday. It's sad how sometimes you don't live up to your childhood dreams and you end up rummaging in wildlife scat.
The education part then briefly informs us that she received a doctorate (of which no title is given, but that is specified to be in "Interdisciplinary Studies" despite being about evolutionary biology), and concludes reporting extensively on criticism of her work.
Then the "Career" section, divided in four small chapters, in this order: "Business", "Books", "Dogs" and finally "Polar Bears".
Then the article ends with a rather large "Criticism" section, which focuses entirely around the climate change issues. Almost all the references throughout the article are coming from a climate change blog or are related to climate controversies.
