The Bahamas is expected to be highly affected by sea level rise because at least 80% of the total land is below 10 meters elevation. [19] [20] As a small island developing state, the Bahamas is vulnerable to escalating disease outbreaks, and climate change could affect the seasonality of outbreaks and transmission of disease. [21]

The Bahamas (/ b ə ˈ h ɑː m ə z / ⓘ bə-HAH-məz), officially the Commonwealth of The Bahamas, [13] is an island country within the Lucayan Archipelago of the Atlantic Ocean.It contains 97% of the Lucayan Archipelago's land area and 88% of its population.
The Blake Basin, also called the Blake–Bahama Basin, is a deep area of the Atlantic Ocean which runs along the east coast of the United States.It starts at the northern part of the Bahamas and continues up toward New York.
The geology of the Bahamas has been researched since the mid-19th century. The islands include Aeolian sands and limestone built on the basement rock of the Florida-Bahamas Platform. The islands are used to infer sea levels based on the arrangement of reef deposits.
Abyssal Zone: Beneath the thermocline is the deep ocean or abyssal zone, where temperatures remain relatively uniform, hovering just above freezing (0°-3°C). This cold, dense water originates from polar regions, where surface water cools, sinks, and spreads towards the equator along the ocean floor, forming the deep ocean circulation system.
The slopes around them however, such as the border of the Tongue of the Ocean in the Great Bahama Bank, are very steep. The Banks were dry land during past ice ages, when sea level was as much as 120 meters (390 feet) lower than at present; the land area of the Bahamas today thus represents only a small fraction of their prehistoric extent.
