These sediments come from the cast iron water mains we have in our network Normally this doesnt aect anyone But a burst water main for example will increase the water ow and can stir up the sediment causing the water to become discoloured Occasional DEEP-SEA SEDIMENTS OF INDIAN OCEAN397Thus in the neighborhood of coral reefs, coral ooze and mud originate.In the open ocean the organic material consists almost exclusively ofthose constituents of th Photomicographs. courtesy of Paula .
