NOVELTY - An eco-mechanical system includes an enduring mechanical system and a surrounding marine ecosystem. The enduring mechanical system comprises articulated chambers (11) arranged in sequences geographically dispersed within areas of the marine ecosystem. The articulated chambers are interconnected together to move deep ocean water to the photic zone utilizing renewable or non-renewable energy sources and keep the deep ocean water in the same zone by thermodynamic heat exchange at same time prevent mixing with warmer water from the ocean surface (2).    USE - Eco-mechanical system for use in de-stratification of ocean sea water.    ADVANTAGE - Deep ocean water is moved into the photic zone and maintained in the same zone close to the ocean surface by thermodynamic heat exchange without being diluted with ambient surface water prior to discharge, enhancing photoplankton activity, which leads to increased fishery production as well as atmospheric carbon fixation, reduced surface water temperature, and even hurricane suppression in some cases. The heat exchanger for maintaining the deep ocean water in the photic zone may be made translucent or pigmented to maximize solar absorption.    DETAILED DESCRIPTION - An eco-mechanical system includes an enduring mechanical system and a surrounding marine ecosystem. The enduring mechanical system comprises articulated chambers (11) arranged in sequences geographically dispersed within areas of the marine ecosystem in the body of ocean water (1). The first of the chambers is an inlet chamber (11'''), while another chamber is a final chamber (11''). Some articulated chambers (11') are located at the ocean surface (2). The articulated chambers are interconnected together by hinges to move deep ocean water to the photic zone utilizing renewable or non-renewable energy sources and keep the deep ocean water in the same zone by thermodynamic heat exchange at same time prevent mixing with warmer water from the ocean surface, reducing ocean surface temperature as result. The marine ecosystem converts inorganic components or nutrients into food through photosynthesis in the photic zone. Part of the food is recycled through the food webs and pyramids of the ecosystem and is converted back into the nutrients through respiration before sinking down into greater depths, depleting the photic zone of its nutrients and slowing down rate of photosynthesis. INDEPENDENT CLAIMS are included for the following:    (1) a pumping apparatus used in constructing the enduring mechanical system; and    (2) a method for increasing phytoplankton growth and reducing ocean surface temperature in a body of ocean water.
