2 BWASP, 1979-2012 COMIDA, 1979-1991, 2008-2012 Collect data on spatial and temporal distribution and behavior of all marine mammal species, and provide information near real-time to stakeholders.

3  Line transect aerial surveys  Twin turbine aircraft with bubble windows  Two dedicated observers plus data recorder  Altitude 1000’-1500’  Bowhead whales, gray whales, belugas Over 540,000 on-effort kilometers flown since 1982, mainly in September and October

6 Gray whales : Hanna Shoal Farther offshore between Wainwright and Icy Cape Sub-Arctic Cetaceans: 1982-2010: 1 fin whale, 1 humpback whale, 1 harbor porpoise 2011-2012: 5 fin whales, 29 humpback whales, 13 minke whales, 18 killer whales

8  Gray whale calves – 67 (2012) vs. 18 (2011)  Walruses – no land haulouts (2012) vs. earliest documented haulout (mid-August 2011)  Bowhead whales frequently observed feeding east/southeast of Pt. Barrow (2012) vs. none (2011)  Bowhead whales in Chukchi Sea in September and October (2012) vs. few (2011)

9  Large survey area ◦ Encompasses areas both near and far from those of current interest to oil and gas industry.  Long-term study ◦ Enables analysis of marine mammal distribution, occurrence and habitat preference over several years; but also allows distinctions between individual years that would not be evident if surveys were sporadic or inconsistent.  Collaborations with researchers from other agencies, (field work and year round).  Provides near real-time information to interested stakeholders. http://www.afsc.noaa.gov/nmml/cetacean/bwasp/index.php

10  BOEM - Jeff Denton and Chuck Monnett  NMML - Phil Clapham, Robyn Angliss, Stefan Ball, and numerous ASAMM observers  Clearwater Air - Andy Harcombe
