MARINE MAMMALS
Marine mammals were scarce throughout the cruise. The majority
of the few seen were along coastal waters. The only spectacular event was
being able to view numbers of Pacific White-sided Dolphins through a sub-
surface view plate as they performed aquatic acrobatics riding the bow wave
in front of the ship. The few sightings are listed below.
