construction of offshore dikes roughly parallel to the shoreline). After a dike is built‚ the polder is drained by pumping out the water. Where the land surface is above low-tide level‚ tide gates discharge water into the sea at low tide and automatically close to prevent reentry of seawater at high tide. To reclaim lands that are below low-tide level‚ the water must be pumped over the dikes. The most notable example of polder construction is the system adjacent to Holland’(Zuider Zee) barrier dam.

The Raft of the Medusa In 1819‚ the French painter‚ Theodore Gerricault‚ created a sensation in Parisian art circles and high-society when he unveiled a huge and impressive canvas entitled "Scene of Shipwreck."

Intertidal rockpool have a relative stable environment where that has few changes in terms of physical conditions when the water reaches low tide (Kemp‚ 2009). Both McAllen & Taylor (2001) and Berschick et al (1987) stated that rockpools undergoes many extreme physic-chemical conditions and few organisms are able to live in rockpools. These abiotic factors have a significant influence in community

Ocean Current and Global Weather The ocean is the largest habitat for life on earth‚ and is vital to the land habitats as well. The ocean regulates the earth’s weather patterns. The main force influencing global climate is the solar energy of the fun. Because the earth is a sphere its surface is not heated equally by incoming solar energy. The equatorial areas receive more sunlight while the poles receive less because sunlight strikes at an oblique angle so much of the sunlight are reflected away
