Thoreau compares his own view of the Atlantic with Darwin's view of the ocean from the base of the Andes mountains and Homer's descriptions of the Mediterranean Sea as if time is no barrier to potential common experience. Hadal zone (the trenches): 6000 m to the bottom of the ocean Though generally described as several separate oceans, these waters comprise one global, interconnected body of salt water sometimes referred to as the World Ocean or global ocean. [14] [15] This concept of a continuous body of water with relatively free interchange among its parts is of fundamental importance to oceanography. [16] The major oceanic divisions – listed below in descending order of area and volume – are defined in part by the continents, various archipelagos, and other criteria. [9] [12] [17] Oceans are fringed by smaller, adjoining bodies of water such as seas, gulfs, bays, bights, and straits.

Wegener used several lines of evidence to support his idea that the continents were once joined together in a supercontintent called Pangaea and have since moved away from one another: (1) the similarity in shape of the continents, as if they once fit together like the pieces of a jigsaw puzzle; (2) the presence of fossils such as Glossopteris, a fossil fern whose spores could not cross wide oceans, on the now widely-separated continents of Africa, Australia, and India; (3) the presence of glacial deposits on continents now found near the equator; and (4) the similarity of rock sequences on different continents , cited: Great Salt Lake (Rookie download online http://eatdrinkitaly.org/books/great-salt-lake-rookie-read-about-geography.

In Florida, for example, the threat level in each threat category remained the same from 2002 to 2004, except for the "other" category. Thus, the composite trend rose by one point from 2002 to 2004, as shown in the far right column, resulting in a increase of threat overall (arrow) download.

The peak, known as a seamount, juts up into a swirling circumpolar current that flows by at 2.5 miles per hour, delivering ample food for the brittlestars to grab while sweeping away fish and other would-be predators. Another brittlestar species has settled on the seamount's flat summit, a habitat normally settled by corals and sponges epub. Their biomass can be estimated by measuring their chlorophyl (green pigment) from light measurements. However, other pigments (brown, red) are also common and the amount of chlorophyl is only a small part of biomass. So, even quantifying the amount of phytoplankton is almost impossible ref.: The Open Ocean (Life in the Sea) http://eatdrinkitaly.org/books/the-open-ocean-life-in-the-sea. In the above table, the conservative gases nitrogen and argon do not contribute to life processes, even though nitrogen gas can be converted by some bacteria into fertilising nitrogen compounds (NO3, NH4).

Since the volume of all oceans is 1.35E21 kg (see table of units & measures ) and CO2 concentration is 9E-5 kg/kg (90ppm), it follows that the total amount of CO2 in all oceans is 12.2E16 kg = 121,000 Pg (Mt) and the partial carbon amount (12/42) = 34,700 Pg (600Pg in surface waters + 7000Pg in mid waters + 30,000Pg in deep ocean = 37,600Pg [1]). Compare this with the amount of carbon in soil and vegetation (1301 + 664 = 1965 Pg, see soil/ecology ) and the carbon in the atmosphere, about 1 kg per square metre over 510E6 km2 = 510E12 kg = 510 Pg (700Pg [1]) ref.: Undersea Animals: A Dramatic Dimensional Visit to Strange Underwater Realms http://sdbec.org/?library/undersea-animals-a-dramatic-dimensional-visit-to-strange-underwater-realms.
