Abstract
A system is provided having a bubble curtain comprising a pipe arranged with holes in respective pipe walls. Compressed air applied onto the pipe generates bubbles of the bubble curtain upwelling colder water from below a seawater surface. A position of the pipe below the seawater surface is a function of a defined target temperature of the cooled seawater surface.

A system comprising a bubble curtain (10) configurable to manipulate a temperature of a seawater surface (18) to be approximately equal a defined target temperature of the seawater surface (18), wherein a pipe (10a) of the bubble curtain (10) is positioned at an adjustable depth below the seawater surface (18) such that an average temperature of respective seawater layers of a sea water column (19) located between a respective one of the adjustable positions of the pipe (10a) and the sea water surface (18) to be approximately equal the defined target temperature and is upwelled and mixed by bubbles released through holes arranged in respective walls of the pipe (10a), wherein the bubbles are ascending and entraining water from the respective seawater layers of the sea water column (19).
