1.   Cruising underwater, you see pale outlines of the irregular sea bottom.

2.   Fisheries are sustained by the plankton which depends upon a constant re-cycling of nutrients stirred up from the sea bottom.

3.   If the photographs are to be believed, the water is azure blue and clear to the sea bottom.

4.   Species somewhat resembling that shown are numerous in the Tertiary Marine formations, and similar species live today in sandy sea bottoms.

5.   The sea bottom is stony, so we strongly recommend you always sail with something on your feet.

6.   A manta glided along the sea bottom.

7.   So it is a comparatively simple step from locating the sea bottom to locating a shoal of fish.

8.   There are two very different kinds of flat fish living on the sea bottom, and they have evolved their flatness in quite different ways.

9.   As sonar scans slowly began painting a more detailed picture of the sea bottom, the data anomaly became a deeper mystery.

10.   As the drilling continues, the rig discharges the muds and the rock cuttings at the sea bottom.
