Do the usual AK thing: Hire an out-of-state contractor to do a survey. Use out-of-state employees who have never seen a walrus. Do a study for ten years, even stationing personnel at the haul out point at an additional charge. Prepare and publish the results/findings, determining that this was only a one time event. Submit vouchers for payment way over the estimated costs, retreat to the lower 48 and wait for the next survey bid notice.
