Section 6 Ocean Primary Production

111 Every ecosystem requires an input of energy. The source varies with the system. In the majority of Ocean ecosystems the source of energy is sunlight that drives photosynthesis done by micro- (phytoplankton) or macro- (seaweeds) algae, green plants, or photosynthetic blue-green or purple bacteria. These organisms produce ecosystem food that supports the food chain, hence they are referred to as Primary producers. The balanced equation for photosynthesis that is correct, but seldom used, is 6CO2 + 12H2O = C6H12O6 + 6H2O + 6O2. Water appears on both sides of the equation because the water molecule is split, and new water molecules are made in the process. When the correct equation for photosynthe-sis is used, it is easier to see the similarities with chemo-synthesis in which water is also a product.

ocean may come and feed here as well as those that live only in the seep ecosystem. This section includes several activities related directly to primary production in the ocean—both by photosyn-thesis and chemosynthesis. Additional exercises found on the OE web site or OE CD include: • Message in the Bottles from the 2002 Arctic Ocean ...

coast of Ecuador found hot vents on the ocean floor spewing a chemical soup of hot fluid. Surrounding these hydrothermal vents was a community of several new animal species— thriving despite living in total darkness with no access to sunlight! These incredible communities have since been found at spreading centers and

The ocean is a sink for anthropogenic CO2 and one of the major transfer modes of CO2 to the ocean from the atmosphere is by gas exchange. 2. Oxygen is a chemical tracer for photosynthesis. The gas exchange flux of O2 is an important parameter for calculating net biological production. 3.

Ocean waves range in size from small ripples to tsunami waves that are ten stories high. The most common cause of waves is wind. The strength of the wind, the distance the wind blows, and the duration of the wind determine how large or small a wave will be. Wavelengths, wave heights, and wave periods are measurements
