The Haps multicore takes four sediment cores at a time. This
picture was taken as it was being lowered into the waters of the Arctic
ocean during the SBI summer cruise. TEA Betty Carvellas worked with Dr.
Jackie Grebmeier on that cruise.

Dr.Lee Cooper, Jim Bartlett and Betty Carvellas are taking sediment samples
from the first Van veen grab on board the USCGC Healy during the summer SBI
cruise. At each sampling station, we lowered the the van Veen grab 5 times
to retrieve sediment from the bottom of the Arctic Ocean along the shelf,
the slope or the basin.
