A sedimentary rock composed almost entirely of calcium carbonate (CaCO3), mainly as calcite. Limestones consist of fragments of shell or of calcite deposits precipitated by certain algae.

Vibrocore

Earth science; Oceanography

A core of sediment taken from the upper stratigraphy of the seabed to a designated depth. The hydraulic vibrocorer is deployed from the deck of a large survey vessel and the individual cores of ...

Attenuation
