Terry Hammar and Al Gagnon labeling cores recovered with the Long Core.

Marking Time (Geologic)

WHOI research associate Terry Hammar (left) and research specialist Al Gagnon label sections of core tube prior to loading them into the barrel of the long core system on R/V Knorr. Each tube is marked with numbers identifying the cruise, the ship, and the core section so it can easily be sorted for storage after the sediments have been retrieved from the seafloor.
