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]
[1] This channel and the Providence Channels are the two main branches of the Great Bahama Canyon, a submerged geological feature formed by erosion during periods of lower sea level. During their early history the Tongue of the Ocean and the Providence Channel were broad, relatively shallow basins flanked by growing carbonate banks. As the ...
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.
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 oceanic zone is typically defined as the area of the ocean lying beyond the continental shelf (e.g. the neritic zone), but operationally is often referred to as beginning where the water depths drop to below 200 metres (660 ft), seaward from the coast into the open ocean with its pelagic zone.
Beyond the eastern edge of the sea, in the Atlantic Ocean, the seafloor drops off rapidly, generally deepening more than 200 metres (650 feet) over a distance of only a few kilometres. As swells from the ocean move west towards the Sea of Abaco, the sudden shallowness can cause the swells to slow down and pile up, building into large waves.
Marine geology or geological oceanography is the study of the history and structure of the ocean floor. It involves geophysical, geochemical, sedimentological and paleontological investigations of the ocean floor and coastal zone. Marine geology has strong ties to geophysics and to physical oceanography.
The Bahamas as seen from space. The egress of the Great Bahama Canyon into the Atlantic Ocean is the dark blue channel at upper center.. The Great Bahama Canyon is a V-shaped [1] submarine canyon system in the Bahamas that cuts between the Abaco Islands to the north and Eleuthera island to the south.
