Sea
lions like to use marina docks as substitute haul outs where natural
land or ice features aren’t available. One might think that walrus
also would use man-made platforms for haul outs where available such
as specially adapted offshore oil platforms in Alaska. perhaps
legislation could be made to require oil corporations to attach
haul-outs for walrus and polar bear on their offshore facilities.
Human compensation for global warming melting of the Arctic ice pack
ought to go ahead in an affordable way.
As
an alternative remedy the federal government could design special
electric engine powered haul out barges that would follow the ice
pack recession seasonally to moor in locations where walrus and polar
bear formerly had ice to rest on. Permanent moorings could be made so
the barges could hook on to anchored tethers with floats that sink
beneath the waves in advance of the return of seasonal ice and
reappear seasonally when signaled or boat-hooked. The barges could
return to the beach of the North Slope in autumn as the ice returns.
