MIRC KB08 Vessel Surveys Feb-Mar 2011

The U.S. Navy Marine Species Monitoring Program

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.

not provided

[2017-08-03] Data format was updated and dataset name was changed.

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.

Overview

This section explains attributes included in the original dataset. OBIS-SEAMAP restricts the attributes available to the public to date/time, lat/lon and species names/counts only. Should you need other attributes described here, you are encouraged to contact the data provider.

Attributes described below represent those in the original dataset provided by the provider.
All attributes are included in the downloadable file (CSV or ESRI File Geodatabase) for "Complete Set of Dataset".
