Cassin's Auklet, Ptychoramphus aleuticus
Above, not a great photo, to say the least, but it captures the usual posture in which birders on pelagic trips see auklets close up: as small gray birds swimming rapidly away from the boat. It also captures the striking white eye, which is the best mark for distinguishing the adult Cassin's from the juvenile Rhinoceros Auklet, which is also small gray and chunky, with a gray bill. Below, a distant and blurry image, showing a Cassin's running over the water on the way to taking off, profiled against the unusually calm mirror surface.
