Comment:
This dataset consists of a compilation from the literature of Holocene opal burial rates from the Southern Ocean calculated using the 230Th-normalization method. Also included is a larger number of surface sediment samples from the Southern Ocean for which opal % and carbonate % measurements were conducted at LDEO, and compiled by Lloyd Burckle in the 1990s and 2000s.
