Saba Bank, Submarine atoll in Caribbean Sea, Netherlands
Saba Bank is a submerged atoll in the Caribbean Sea, formed by a shallow limestone platform that sits just below the water's surface. It lies west of the island of Saba and forms one of the largest atolls in the Atlantic Ocean.
The area was designated a protected marine zone in the early 2000s after scientists drew attention to its rich marine life. It was later recognized as a Particularly Sensitive Sea Area under international maritime law, giving it a higher level of protection.
Marine researchers conduct regular expeditions to study the bank's biodiversity, documenting over 200 fish species and multiple whale populations.
Anchoring is banned throughout the protected zone to avoid damage to the seafloor and coral. Anyone planning to visit should check the relevant maritime rules in advance, as they are strictly enforced.
Although the bank is almost entirely submerged, it is so shallow in some spots that rough seas can cause waves to break visibly at the surface. This makes it a navigational hazard for boats passing through the area without detailed charts.
