Controls on biogenic silica burial in the Southern Ocean ...

By subdividing the Southern Ocean on the basis of oceanographic regions and interpolating the opal burial rates, we estimate a total biogenic Si burial south of 40°S of ± Tmol Si yr1. In both the seasonally icecovered and permanently icefree regions we can explain 73% of opal burial variability from surface ocean properties.

In most slowly accumulating deepsea sediments (rates of 2×10 −3 cm y −1 or less), nearly all of the biogenic silica deposited on the seafloor dissolves prior to longterm burial.
