As you move away from the ridge spreading center the sediments get progressively thicker (see section 4.5), increasing by approximately 100-200 m of sediment for every 1000 km distance from the ridge axis. WebAt depths greater than 16,400 feet (5,000 metres), the calcium carbonate content decreases, and the calcareous deposits give way to red clay. This is why ocean acidification is such a major issue in modern oceanography. one of a group of planktonic amoeba-like animals with a calcareous shell, which contributes to biogenous sediments.
