Data Attributes

Attribute Summary

Rubric Score Primary Key? Name Type Description
100
DEPTH NUMERIC Depth in meters (negative values)
100
LATITUDE NUMERIC Y-coordinate in decimal degrees, WGS 84
100
LONGITUDE NUMERIC X-coordinate in decimal degrees, WGS 84
100
REGION TEXT One of five areas in the U.S. Pacific Islands Region where data were collected. PRIA = Pacific Remote Island Areas AMSM = American Samoa NWHI = Northwestern Hawaiian Islands MHI = Main Hawaiian Islands MARI = Mariana Archipelago
100
ISLAND TEXT 3-letter code for the island/atoll where the data were collected in the U.S. Pacific Islands Region. See the lookup table included in the distribution section named LIST_OF_ISLANDS.csv
100
DATETIME DATE 2012-2015 data only: The UTC date and time in m/d/yyyy h:mm:ss 24-hr format.
100
FIXTYPE NUMERIC 2012-2015 data only: the fix/GPS quality indicator (1 or 2). 0= Invalid fix 1 = GPS fix 2 = DGPS fix
100
SATELLITES NUMERIC 2012-2015 data only: the number of satellites tracked/in use at the time of the fix, that is, when the position is calculated/recorded. Values range from 0-12. Null values only occur with fixes acquired from March 2014 to April 2015 with the GPSMAP 3006c.
100
HDOP NUMERIC 2012-2015 data only: horizontal dilution of precision. A measure of the geometric quality of a GPS satellite configuration in the sky. HDOP is a factor in determining the relative accuracy of a horizontal position. The smaller the DOP number, the better the geometry. Values range from 0.7 to 12. HDOP = 99, no satellites were tracked/in use
100
EST_H_ERROR NUMERIC 2012-2015 data only: estimated horizontal position error in meters. Values range from 0-130.
100
GPSMODEL TEXT 2012-2015 data only: GPS Map 178c used on the Safe Boat small boat 2012 during ASRAMP 2012. GPS Map 740s used on the Steel Toe small boat in 2012 in Tutuila, American Samoa only. GPS Map 3006c used on the Rubber Duck small boat from 2012 to 2015.
100
DATE DATE 2016 to present: the UTC date in m/d/yyyy format.
100
TIME TIME 2016 to present: the UTC time in h:mm:ss 24-hr format.
100
SPEED NUMERIC 2016 to present: velocity of the small boat at the time of the fix in meters per second.
