Rosemary Bank
Encyclopedia
Rosemary Bank is a seamount
in the Rockall Trough in the northeast Atlantic. It is approximately 120 km west of Scotland.
The feature originated 70 million years ago as a result of volcanic activity. The sea bed immediately surrounding the seamount is approximately 2300m below sea-level; Rosemary Bank rises to approximately 2000m, the highest point being 300m below sea-level.
Around the base of Rosemary Bank is a thin "moat" where the sea-bottom is at a lower depth than the surrounding terrain.
It was discovered in 1930 by the survey vessel HMS Rosemary from which it takes its name.
