The image is a map of Chandeleur Islands, located in the Indian Ocean. The map is color-coded to show the calm conditions of the islands, with different colors representing different levels of calm conditions. The colors range from light blue to dark blue, with some areas being darker blue and others being lighter blue.

The map also includes a legend that explains the different colors and symbols used to represent the different levels. The text on the map reads "Calm Conditions" and "High Tide + Surge + Waves". Below the legend, there is a bar graph that shows the elevation of the island, with the highest tide and the lowest tide. The bar graph shows that the island is not affected by the high tide, as indicated by the "Elevations Not Affected" text. The USGS logo is also visible in the bottom right corner of the image.
