“It gets much noisier when seismic exploration is taking<br />

place,” said Hildebrand. Humans need ear protection<br />

for sound above 80 decibels (dB), and Hildebrand’s<br />

group detected sounds of 250 dB when the air guns<br />

used for seismic exploration were fired. “You can’t go<br />

out and put ear protection on whales.”<br />

Hildebrand’s group has confirmed, however, that<br />

the Chukchi’s seabed in the area targeted for exploration<br />

is both shallow and flat. “Because of that flat continental<br />

shelf, when you make sounds like the air guns it propagates<br />

a long way. That means that you could be 100 miles<br />

away and you’d still hear it.”<br />

Just how difficult would it be to drill in these waters?<br />

Drill rigs and wells would be subject to the Arctic<br />

Ocean’s ice, high winds, and strong currents. During the<br />

approximately 100 summer days of open water, when exploratory<br />

drilling would occur, ice floes and icebergs pose<br />

a danger. Moving ice four miles wide has been seen in<br />

the Beaufort. In the Chukchi, Hank has seen two-story ice<br />

ridges—formed when currents smash ice floes into each<br />

other. How an offshore platform and its pipelines would<br />

fare in an encounter with what scientists call “an extreme<br />

ice feature” is still not fully known.<br />

And if a spill occurred? <strong>The</strong> Beaufort lies north of the<br />

North Slope’s Prudhoe Bay, which has basic infrastructure<br />

and could serve as a rudimentary staging area. However,<br />

much of the Beaufort coastline does not. <strong>The</strong> Chukchi,<br />

<strong>The</strong> entire U.S. population of polar bears, already facing grave<br />

challenges as the ice pack shrinks, is found along Alaska’s<br />

northern coast and would be in greater jeopardy if drilling<br />

occurs in the Beaufort and Chukchi seas. Among other species<br />

that could be harmed is the walrus.<br />

off Alaska’s northwest coast, is remote, essentially undeveloped,<br />

and lacks basic infrastructure. (If oil is extracted<br />

from the Chukchi, it probably would run through a proposed<br />

280-mile pipeline crossing the National Petroleum<br />

Reserve-Alaska, which contains biologically sensitive wilderness,<br />

and hook up to the Trans Alaska Pipeline.)<br />

<strong>The</strong> U.S. Coast Guard would be responsible for<br />

cleanup in the Arctic Ocean, and its base nearest to the<br />

drilling sites is in Kodiak, more than 1,000 miles away.<br />

“We have extremely limited Arctic response capabilities,”<br />

Admiral Robert J. Papp, Jr., testified before a U.S. Senate<br />

subcommittee in August. “We do not have any infrastructure<br />

on the North Slope to hangar our aircraft, moor our<br />

boats or sustain our crews. I have only one operational<br />

icebreaker.”<br />

Brenda Pierce, program coordinator of the Energy<br />

Resources Program at the U.S. Geological Survey (USGS),<br />

co-authored a report on oil spill preparedness if drilling<br />

were allowed in the Arctic Ocean. <strong>The</strong> survey of 400 scientific<br />

publications and science policy documents on the<br />
