- The Saya de Malha Banks — by Marjo Vierros — last modified May 01, 2010 02:55 PM
- The Saya de Malha Banks are the largest submerged banks in the world containing a unique seagrass biotope in the open ocean. Due to their remoteness, the Saya de Malha Banks are host to some of the least explored shallow tropical marine ecosystems globally, completely detached from land boundaries, and providing an ecologically important oasis of high productivity in the Indian Ocean.
- The Sargasso Sea — by Sheila McKenna, Arlo Hemphill — last modified Sep 08, 2009 12:25 PM
- Alone in supporting the center of distribution for a holopelagic (continuously pelagic) drift algae (Sargassum spp.) community, the Sargasso Sea is a globally unique marine ecosystem whose entire water column provides a range of critical services (e.g. habitats, migratory routes, spawning and feeding grounds) to a multitude of species including endemic, endangered and commercially important ones. To illustrate how such an area can meet the EBSA criterion for uniqueness, information on the biological, ecological and oceanographic features of the Sargasso Sea from peer reviewed literature, technical reports and data sets were examined and compared to the four other similar regions of the ocean found within subtropical gyres.
