Paleo Slide Set: Heinrich Events: Marine Record of Abrupt Climate Changes in the Late Pleistocene
CSS Hudson
Scientists use ships like the Canadian government research vessel CSS Hudson, shown here, to extract sediment cores from the world's oceans. Since the 1950s, thousands of cores have been collected and are now archived at various facilities around the world. These cores have provided a great deal of information about past changes in both the Earth's climate and the ecology of marine and terrestrial environments. In order to obtain long sediment cores from the ocean floor, researchers need relatively large ships with heavy-duty winches -- for example the CSS Hudson is 110 meters in length.
