Samoa DMWR) observers, Max Cremer pilot. Trackline generalized from raw nav. Purpose: (1) Investigate full extent of sheer carbonate wall encountered on P5-648. Find base and then video and photographic survey north, wall to ledge and then E at a contour of interest, making observations of biota and physical structure (2) Species identification of as many corals and fish as possible Supplemental_Information: Time_Period_of_Content: Time_Period_Information: Range_of_Dates/Times: Beginning_Date: July 11, 2005 Ending_Date: July 11, 2005 Currentness_Reference: current Status: Progress: Complete Maintenance_and_Update_Frequency: As needed Spatial_Domain: Bounding_Coordinates: West_Bounding_Coordinate: -170.6695 East_Bounding_Coordinate: -170.6580 North_Bounding_Coordinate: -14.3224 South_Bounding_Coordinate: -14.3332 Keywords: Theme: Theme_Keyword_Thesaurus: None Theme_Keyword: benthic habitat Theme_Keyword: marine ecology Theme_Keyword: submersible Theme_Keyword: bathymetry Theme_Keyword: exploration Theme_Keyword: coral reef Place: Place_Keyword_Thesaurus: None Place_Keyword: American Samoa Place_Keyword: Tutuila Place_Keyword: Taema Bank Place_Keyword: Western Pacific Place_Keyword: SW Pacific Place_Keyword: Polynesia Place_Keyword: Fagatele Bay Access_Constraints: unlimited Use_Constraints: hold until after PI has a chance to publish, by July 2007 Point_of_Contact: Contact_Information: Contact_Organization_Primary: Contact_Organization: Oregon State University, Dept. of Geosciences, Davey Jones Locker Lab Contact_Person: Dr. Dawn J.
