In 1976, John D. Isaacs proposed to use wave energy to invert the density structure of the ocean and pump deep, nutrient-rich water into the sunlit surface layers. The basic principle is simple: a length of tubing attached to a surface buoy at the top, and a one-way valve at...
In the North Pacific Subtropical Gyre (NPSG), the regular occurrence of summer phytoplankton blooms contributes to marine ecosystem productivity and the annual carbon export. The mechanisms underlying the formation, maintenance, and decay of these blooms remain largely unknown; nitrogen fixation, episodic vertical mixing of nutrients, and meso- (<100 km) and...
The status of vitamin B-6 (B6) nutriture of nine
persons (4F;5M) with insulin dependent diabetes mellitus
(IDDM), nine persons (5F;4M) with non-insulin dependent
diabetes mellitus (NIDDM), and 18 control individuals
(9F;9M) was evaluated, using biochemical and dietary
indicators of B6 status. The biochemical indices employed
were plasma concentration of pyridoxal...
