The objective of this current survey effort was to conduct baseline surveys to further document
marine mammal and sea turtle occurrence in nearshore waters around the island of Guam. This
report presents the results of the Guam Marine Species Monitoring Survey conducted on the MV
Island Girl from February 17 to March 3, 2011. This survey covered an area of approximately
4,100 square kilometers (km2)(1,200 square nautical miles ([nm2]) to document marine mammal
and sea turtle distribution around the island of Guam. The approach primarily followed
opportunistic survey protocols used in a recent survey around Guam (Ligon et al. 2011), which
remained nearshore (within 5.6 kilometers [km] or 3 nautical miles [nm] of the coastline). ). The
resulting sightings, therefore, consisted of spinner dolphins (Stenella longirostris; 7 of 9
sightings) and a mixed group of bottlenose dolphins (Tursiops truncatus) and short-finned pilot
whales (Globicephala macrorhynchus). In addition, one species of sea turtle was observed (green
sea turtle, Chelonia mydas). Additional lines of effort following standard line-transect protocols
were attempted (out to 10 nm from shore) when sea conditions permitted.
The sighting of short-finned pilot whales and bottlenose dolphins on 02/22/11 was an aggregation of the two species and recorded as a single record. This sighting was split into each species in this dataset.
