Image Of the Day caption:
Researchers and crew aboard the WHOI research vessel Knorr tested a new long corer system for the first time in 2007. The WHOI long corer, developed by Jim Broda and William Curry at WHOI, acts like a giant probe, plunging up to 150 feet into the seafloortwice as long as other systemsand collecting mud in its hollow open pipe. This longer reach provides access to deeper, older sediments, and thus a look further back into Earth history. The sediments contain fossils that reveal past sea-level changes, ocean circulation, and Earths climate, spanning hundreds of thousands and even millions of years.
