Maintenance and Update Frequency: notPlanned Statement: Material collected using a Kullenberg core aboard the research vessel Marion Dufresne. The method used to produce the diatom slides is detailed in the 'methodology' document uploaded with this record. Statement: The sediment was sampled every 10cm from the sediment surface down to a depth of 490cm. Parameters: Core depth (cm), diatom species, diatom subtotal and silica subtotal.

Core MD88-784 was recovered during the French ASPARA IV cruise in 1988, aboard the Marion Dufresne. The core was located on the Tasman Fracture Zone of the Mid-Ocean Ridge, within the Polar Front Zone. Diatoms were found in abundance through the core, with a total of 57 diatom species and taxa recorded. This data set provides the raw diatom counts from sediment samples prepared every 10cm down the core.
