Sonar image of ocean floor off Louisiana, USA
Sea floor off Louisiana. High-definition coloured sonar image of the continental shelf off the Louisiana coast, USA. This most detailed mapping of the Gulf of Mexico ocean floor off the North American coast was made by ships recording sound echos from the ocean bottom. Colours show depths of the ocean floor: white (near sea level), orange (1000 metres), yellow (2000 m), blue (3000 m). On this continental shelf sediments have been deposited by the Mississippi river. Buried salt and its movement beneath these sediments creates a pock-marked landscape that resembles the moon. The salt arose from evaporation in the Gulf of Mexico

EDITORS COMMENTS
This stunning print captures a high-definition colored sonar image of the ocean floor off Louisiana, USA. The continental shelf off the Louisiana coast is beautifully depicted in this most detailed mapping of the Gulf of Mexico's ocean floor along the North American coast. The image was created by ships recording sound echoes from the ocean bottom. The colors in this image represent different depths of the ocean floor, with white indicating areas near sea level and orange, yellow, and blue representing depths of 1000 meters, 2000 meters, and 3000 meters respectively. It is fascinating to observe how these depth variations create a mesmerizing landscape beneath the surface. The continental shelf off Louisiana has been shaped by sediments deposited by the mighty Mississippi River over time. However, what truly sets this region apart is its unique pock-marked landscape reminiscent of our moon. This distinctive feature is caused by buried salt formations that move beneath these sediment layers due to evaporation in the Gulf of Mexico. This print not only showcases nature's beauty but also serves as an invaluable scientific resource for studying underwater topography and understanding geological processes at work on our planet's seabeds.
