Description:

Abstract:

Seafloor character was derived from interpretations of aerial photograph-derived kelp-distribution data available for Santa Cruz Island in the Santa Barbara Channel, California (Kushner and others 2013). The number of substrate classes was reduced because rugosity could not be derived for all areas.

Purpose:

These data are intended for science researchers, students, policy makers, and the general public. These data can be used with geographic information systems or other software to identify local seafloor character.

Data_Quality_Information:

Attribute_Accuracy:

Attribute_Accuracy_Report: Pixel resolution 10 m.

Logical_Consistency_Report:

Classification was done on the basis of kelp distribution polygons delineated by interpreter.

Completeness_Report:

Data covers less than half of the coastline of Santa Cruz Island.

Positional_Accuracy:

Horizontal_Positional_Accuracy:

Horizontal_Positional_Accuracy_Report:

Positional information reflects the WAAS-enabled GSP unit, recording at between 1 to 2 nm. DGPS (WAAS) accuracy for position is less than 3 meters. (From Garmin GPSMAP 76C/76CS Specifications, M01-10108-00, Rev0304, <https://http://www8.garmin.com/specs/GPSMAP76C_76CSspec.pdf>).
