Oozes on the seafloor mostly consist of
WebDeeper in the ocean, changes in temperature, pressure, and water chemistry cause calcareous tests to dissolve. At a certain depth, the tests dissolve faster than they accumulate, so calcareous oozes do not form below this depth; this depth is called the calcite compensation depth (CCD) (Figure 2). The depth of the CCD varies from one … Webseafloor and recovered long cylinders of sediment. You will read about the sediment, “pull-up” cores of sediment, and view an image of the same sediment as seen under a microscope. This will give you multiple views of the seafloor: from the global scale of Google Earth, down to a 7-cm diameter core, and at the microscopic level.
