Vertical Distribution of Biogenic Elements in Pore Waters of the Bering Sea.
Piston core samples of Bering Sea sediments were squeezed to obtain the interstitial fluids. Horizons sampled and reported are for 0, 2, 4, 8 and 16 m. These fluids were subsequently analyzed for alkalinity, ammonia, phosphate and silicate. Alkalinity and ammonia concentrations in the pore fluids in...
