A Survey of the Seas

O, Lord, how manifold are thy works! in wisdom hast thou made them all: the earth is full of thy riches. So is this great and wide sea, wherein are things creeping innumerable, both small and great beasts. -Psalm 104:24-25

I was reading about the ocean in my science book. I thought this was pretty neat:
Deeps and trenches. Any area of the sea that exceeds 6000 meters(19, 685 ft) in the depth is called an oceanic deep. The greatest deeps are found in the trenches, huge muddy valleys that cut through portions of the abyssal plains; some trenches may be as much as 2400 km (1500 mi) long. At least five trenches deeper than 10,000 m (33,000 ft) are known.
The deepest known point in the sea, called the Challenger Deep, is located in the Marianas Trench in the South Pacific near Guam. Its floor rests 10,911 m (35,797 ft) below the surface-nearly 7 miles. If Mount Everest, the tallest mountain in the world were placed in the Challenger Deep, its peak would be covered be nearly 2 km of water! The weight of nearly 11 kilometers of water presses down with a force of 15,900 psi (1070 bar), or 1145 tons per square foot.
The Challenger Deep was first explored by the research submarine Trieste in a record-breaking dive in January 1960. As Trieste's searchlights, proving that living creatures inhabit ever the deepest regions of the oceans.

Here is something else that caught my interest:
Fish with Antifreeze
You are probably familiar with the concept of antifreeze, a substance added to water in a car's radiator to keep it from freezing during the winter. When antifreeze (a substance called ethylene glycol) is dissolved in water, it lowers the freezing point of the water, allowing it to remain a liquid at temperatures below its ordinary freezing point.
God equipped certain fish with a type of "antifreeze" that enables them to endure frigid temperatures. Portions of the Ross Sea in Antarctica are so cold that most fishes' blood would freeze if they were to remain there for long. Yet several species of fish, including the dragonfish, dwell happily in the Ross Sea; although their blood temperatures drop far below the freezing point of the ordinary blood, their blood never freezes.
Scientists have discovered that certain proteins found in the blood of these fish, dubbed "antifreeze proteins," appear to prevent their blood from freezing. The way in which these proteins function is not fully understood, but it is evident that the are there by design, thanks to the great wisdom of the Creator.
