Seismic airgun blasting is used to search <br />for oil and gas deposits deep below the <br />ocean floor. <br />• Ships tow multiple seismic airguns <br />through the water. <br />• Seismic airguns shoot dynamite -like <br />blasts of compressed air through the <br />ocean and miles under the seafloor. <br />• Sound waves travel back to the <br />surface with information about the <br />location of possible oil and <br />gas deposits. <br />• Seismic airguns, which create one of <br />the loudest manmade sounds in the <br />ocean, are fired every 10 seconds, <br />for days to weeks on end. <br />Seismic airgun blasting is being considered in <br />an area twice the size of California, stretching <br />from Delaware to Florida, but its impacts <br />could be felt along the entire East Coast. <br />p.,m.yynN. <br />600600e.m <br />Bout C.m10. <br />0.45 <br />C Bureau of <br />�Legend <br />1 1 ets.of 1 20 cmcnnoicey <br />09 O E14.010 HIR6._TGI-00000. <br />Q E14-000_213SpecImmG00 <br />E11.006 mroGrey_Anxax <br />E1.1.007_00_PGS <br />Ocean Energy Management, <br />0 65 100 200 090 520 <br />was. <br />'96my Polygon we da *ne Iron public information mops <br />O E14-008 20 Spec40maeo n E1/.001 2G_TGS <br />E11-000 2D CGG Plannlnp Aron <br />E14-001 20 WO.IarnG0e0 �� SlateSAllonlIc <br />E11-0032QGATachnobpy <br />E 11.002_WAll0rown <br />May 2015 <br />Offshore oil and gas development along the <br />Atlantic could put at risk some of the nearly <br />1.4 million jobs and over $95 billion in gross <br />domestic product that rely on healthy ocean <br />ecosystems, mainly through fishing, tourism <br />and recreation. <br />Occana, A Deaf Whale is A Dead Whale, April 2013 Occana, Offshore Energy by the Numbers, January 2015 <br />On March 5, 2015, 75 leading marine <br />scientists sent a letter to President <br />Obama, urging him to reject the <br />Department of the Interior's analysis <br />and its decision to introduce seismic <br />airgun blasting in the Atlantic Ocean. <br />`...the proposed seismic activity <br />is likely to have significant, <br />long-lasting, and widespread <br />- impacts on the reproduction <br />and survival of fish and marine <br />mammal populations in the <br />region, including the critically <br />endangered North Atlantic <br />right whale, of which only 500 <br />remain. Opening the U.S <br />east coast to seismic airgun <br />exploration poses an unacceptable <br />risk of serious harm to, marine <br />life at the species and <br />"„population levels.::” <br />
