Purpose:

Determine the number of red snapper residing in uncharacterized (unknown) habitat from Alabama, Mississippi, Louisiana, and Texas.

Data Parameters and Units:

OBJECTID_12 A unique code corresponding to each sampling interval for the Red Snapper Abundance project OBJECTID A unique code corresponding to each sampling interval (continuous number for all CBASS samples) Join_Count The number of samples in the sampling interval TARGET_FID Same as OBJECTID SITE Site name of sampling location DATE_ Date of sample CBASS_lon Longitude in decimal degrees CBASS_lat Latitude in decimal degrees Survey_Method Sampling technique/gear used Habitat_Score Habitiat sampled (1= UCB, 2= low relief natural, 3= high relief natural) Area_Surveyed__sq_m_ Area surveyed in m2, estimated from towed camera location from the bottom and camera field of view Red_Snapper_Count Number of Red Snapper counted in sampling interval Red_Snapper_Density__per100sqm_ Density (per 100m2) of Red Snapper in the sampling interval State State/region sampled OBJECTID_1 State_DepthZone State and depth zone sampled State_DepthZone_1 State and depth zone sampled DepthZone Depth zone sampled State_1 State/region sampled Distance Distance of tow (km)
