The National Oceanic and Atmospheric Administration (NOAA) website features maps which
demonstrate the massive collapse of Gray Whale numbers from
their historical distribution.

This GIS map details some of the major threats to the Eastern North Pacific Gray Whale.
Data has been obtained from relevant US agencies. More data will be included as details come to hand.
The GIS has been developed by Greg Luker, GIS Laboratory, Southern Cross University, Lismore, NSW Australia.

FROM THE REPORT
4.2 The Federal Government has recently sold 29.4 million acres in the Chukchi Sea for oil lease sales.
Within this lease sale is critical feeding habitat for the ENPGW.

1.2 The migration route takes the whales past one of the most heavily industrialised coastlines in the world. Thus exposing the population to marine pollution, vessel traffic, industrial noise and activities associated with the development of the outer continental shelf resources, fishing entanglements, bottom trawling, industrial
development, military and non military sonar across its entire range.
THIRTEEN PROPOSED LIQUID NATURAL GAS TERMINALS PROPOSED
ALONG MIGRATION ROUTE encompassing California, Oregon,
Washington, Western Canada and Baja-Mexico.
The construction of these terminals would cause underwater noise and the operation of the terminals would exceed current ambient noise levels. Noise can disrupt migration and other important behaviours.
