In two samples from Hole M0020A with brownish biofilms, moderate to high phosphatase activities were measured. Other exoenzymes were absent or were very low in activity. In Hole M0005E, the extraordinary high activity in near-surface samples possibly originates from eukaryotic organisms living near the sediment surface that were mixed in the sediment by the hammer-coring method applied in Hole M0005E.
