Der Vema ist ein 980 Kilometer westnordwestlich von Kapstadt im Südatlantik liegender Tiefseeberg, der aus einer Tiefe von ungefähr 4600 Metern empor ragt. Er hat die Form einer Tiefseekuppe, auch Guyot genannt, – mit kegelförmiger Struktur und abgeflachter Spitze – und ist vor ungefähr 11 Millionen Jahren vermutlich durch einen vulkanischen Hotspot entstanden. (de) Vema Seamount is a seamount in the South Atlantic Ocean. Discovered in 1959 by a ship with the same name, it lies 1,600 kilometres (1,000 mi) from Tristan da Cunha and 1,000 kilometres (620 mi) northwest of Cape Town. The seamount has a flat top at a mean depth of 73 metres (40 fathoms) which was eroded into the seamount at a time when sea levels were lower; the shallowest point lies at 26 metres (14 fathoms) depth. The seamount was formed between 15-11 million years ago, possibly by a hotspot. The seamount rises high enough that its summit is at shallow depth, allowing sunlight to reach it and thus permitting the growth of kelp and algae. A number of sea animals and fish are encountered on the seamount; active fisheries existed at Vema Seamount and caused the disappearance of some animal species. (en) |
