WebJan 1, 2016 · Marine geologists have difficulty accessing deep-sea sediments, because the average ocean depth is ~3,800 m and recovery of ocean bottom samples is technically challenging and time consuming. While sampling is hard, geophysical methods that use acoustic pulses are much easier to perform at sea than on land. WebMarine sediments are thickest near the continental margins (refer to figure \(\PageIndex{1}\)) where they can be over 10 km thick. This is because the crust near passive continental margins is often very old, allowing for a long period of accumulation, and because there is a large amount of terrigenous sediment input coming from the …
