A Coast Guard helicopter aircrew from Coast Guard Air Station Atlantic City, N.J. takes two scientists from the National Oceanic Atmospheric Administration to search for dolphins off the coast of Sandy Hook, N.J., Tuesday Feb. 10, 2009. The survey will be the first aerial survey and the first since ice formation in the rivers precluded water-based sighting surveys, last conducted on January 13 when five animals were confirmed to still be in the rivers.
