Features. The TOTO is a U-shaped, relatively flat-bottomed trench measuring approximately 30 by 240 kilometres (20 by 150 mi). Its depth varies gradually from 1,100 m (3,600 ft) in the south to 2,000 m (6,600 ft) in the north.
Is the Bahamas below sea level?
The Bahamas is very geographically shallow. The majority of the population lives in the capital, an island city called Nassau. The city is mostly under 10m above sea level and is populated by more than half of the nation, so Nassau is very vulnerable to sea level rise.
What is the largest bank of water in the Bahamas?
Great Bahama Bank
The largest is Great Bahama Bank. It began building as early as the age of the dinosaurs, more than 65 million years ago. Large coral reefs built up at the bottom of the sea.
What is the Great Bahama Bank made of?
reef limestone
The Great Bahama Bank is a pile of coral reef limestone at least 4500 m thick that has been accumulating since Cretaceous time. The entire pile was deposited in warm shallow water, so the foundation crust must have been slowly subsiding at an average rate of at least 3.6 cm per 1000 years (Newell, 1955).

Is the Bahamas sinking?
Many small island nations will be catastrophically affected by sea-level rises in the future, including The Bahamas, which was devastated by Hurricane Dorian in 2019. Most of Grand Bahama, including Nassau (pictured), Abaco and Spanish Wells are projected to be underwater by 2050 because of climate change.

Where is the Great Bahama Bank located?
Great Bahama Bank. Great Bahama Bank, large shoal off The Bahamas, separated from Little Bahama Bank (north) by Northwest Providence Channel.

Where are the tongue of the ocean and Grand Bahama Bank?
This extraordinary image captures the meeting place of the deep waters of the Tongue of the Ocean and the much shallower, completely submerged Grand Bahama Bank. This platform reef drops off quickly into the branch of the Great Bahama submarine canyon that because of its shape is called the Tongue of the Ocean.
What are the characteristics of the banks of the Grand Bahama?
To the north, another bank underlies another set of islands, including Grand Bahama. The varied colors of these banks suggest their surfaces are somewhat uneven. The banks’ distinct contours, sharply outlined in dark blue, indicate that the ocean floor drops dramatically around them.
