... University, Tainan, TAIWAN, China ABSTRACT Deep ocean water (DOW) is commonly referred to the water below 200 meters in the ocean that is typically cold, clean, stable, and rich in nutrients and minerals. Japan and the United States have been exploiting the DOW for applications in water, pharmaceutical...

... of a unit of meat requires several units of cereal. These factors argue for the development of new sustainable technologies to enhance production of food, and animal protein in particular. One candidate food production technology is ocean fertilization using deep ocean water (DOW). DOW is cold, nutrient...

.... Primary productivities in the most of ocean are then expected to be enhanced if nutrient availability for primary producer is improved (Takahashi and Ikeya, 2004). Deep ocean water (DOW) is cold, nutrient-rich and pathogen-free seawater found at depth of several-hundred meters or lower. The DOW has...

... ABSTRACT: So far, there are no successful means to upwell Deep Ocean Water (DOW) artificially and to make a fishing ground in the open sea. The five years project of increasing a primary production and making a new fishing ground by upwelling DOW which is very rich in nutrient salt...

... ABSTRACT: The Marino-Forum 21 initiated the research project on development of fishing grounds by utilizing Deep Ocean Water (called DOW here after) of 200 m deep. We plan to enhance the component of nutrient salts in the sea area concerned by discharging DOW into the euphotic layers aiming...

... will be a methodology to enhance ocean nutrient by discharging deep ocean water (DOW) with rich nutrient into photic zone by applying an upwelling device moored in the ocean, that leads to make the seawater of euphotic zone fertile with phytoplankton. This device can be called as the Ocean Nutrient Enhancer (ONE...

... ABSTRACT: For the purpose to make a fishing ground in the sea by increasing the primary production, The Ocean Nutrient Enhancer (ONE for short) which rises the nutrient-rich Deep Ocean Water (DOW) and discharges it into the euphotic surface layer has been studied. To establish the concept...

... ABSTRACT: In this paper, we propose the Deep Ocean Water (DOW) Upwelling Machine which is driven by the Ocean Thermal Energy Conversion (OTEC) for the purpose to increase the primary production in the stratified sea area of low latitude, so called "the sea of desert". In the area...
