Digital Mosaic of the GLORIA data of the Gulf of Mexico

Background

In the late summer and fall of 1985, the USGS conducted surveys of the Exclusive Economic Zone (EEZ) in the Gulf of Mexico and around Puerto Rico and the U.S. Virgin Islands. The 1985 survey abutted an area surveyed in 1982 as part of the Outer Continental shelf geohazards work that focused on the Texas-Louisiana continental slope and preliminary work for the Deep Sea Drilling Project in the Mississippi Fan. The collected GLORIA data was processed and digitally mosaicked to produce continuous imagery of the seafloor. The 1982 and 1985 datasets were combined to produce sidescan coverage of the EEZ in the Gulf of Mexico. A total of 16 digital mosaics of a 2 degree by 2 degree (or smaller) area with a 50 meter pixel resolution were completed for the Gulf of Mexico. The individual mosaics were later combined to produce an overview of the Gulf of Mexico. A reduced version of the completed digital mosaic of the Gulf of Mexico is provided here.
