Because of the slow accumulation of sediment in midocean this tiny core of mud may represent thousands or even hundreds of thousands of years. Scientific interest lies in measuring the thickness of these stratifications of mud cores in order to determine former changes in depth and climate. Telegraph companies are particularly interested in this work, because they wish to learn how fast matter accumulates on the sea bottom in order to avoid laying cables in regions where the rate of deposition...
...Darwin the collecting was poor owing to the large amount of sediment in the water, and only 65 species of echinoderms were found, according to Professor Clark...
