The scientific crew worked 12 hour shifts for 42 days aboard the Knorr.
The research vessel Knorr anchored in Costa Rica.
Core Comes Aboard
A 10-foot (3 meter) core of the seafloor comes aboard the R/V Knorr. Scientists analyzed the oxygen levels inside the sediment to measure the metabolisms of microbes inside.
