... The Cypris, which are a multi-cellular organism, that are usually between .5 and 3 mm long. They are most commonly found among water vegetation and on the surface layers of mud. • The Diatoms, which are singe celled organisms that measure between 5-500 microns. They can be found attached to plants. They ... usually form brown crusts on the surfaces of under water objects such as stones and plant stems. • The Daphnia, which are multi-cellular organisms that measure between .5 and 4 mm. They are ... .25 mm and 3 mm. They can be found among plants and organic matter. The Cyclops cont...

... conservation priority. Coral reefs around the world are being destroyed at a faster rate than they can recover, therefore putting them in great danger. One of the largest causes of the destruction of the reefs is global warming, which has been increasing the temperature of the ocean water resulting in coral bleaching. Human-induced climate change has already led to substantial changes in a variety ... It is a stress condition that involves a breakdown of the symbiotic relationship between corals and unicellular algae called zooxantheallae. Zooxanthellae are photosynthetic, and have a symb...

... relationship. The algae turn sunlight into carbon and sugars, which are then available to the polyp. In turn the polyp filters particles out of the water and excretes waste (nitrogen and phosphorus) that becomes available to the symbiotic algae. It's this very tight nutrient recycling within the coral itself ... storms also damage reefs and devastate coastal areas. While large waves cause severe short-term damage to reefs, recovery is rapid, and part of a cycle of disturbance and recovery that helps shape healthy coral reefs. When the reef is already stressed by pollution or over fishing...

... and algae plants that live inside the coral tissue. Thus the coral reacts expelling the algae and eventually lose its color, appearing "bleached". Coral reefs are extremely sensitive, slight changes in the reef environment may have detrimental effects on the health of the coral polyps. There are numerous changes, but they generally fall into two categories: natural disturbances and anthropogenic disturbances (Guilcher ... . This problem was observed in at least 60 countries and island nations, only the central Pacific region was spared. The rise in water temperatures is a direct result o...

... need to be sure that we are using remote sensing to promote wise costal practices in so far as coral reefs. Coral reef color essentially refers to digital remote sensing of coral reefs. The most common application of remote sensing in coral reef environments is geomorphological mapping. This is because, historically sensor capabilities have been sufficient to identify only broad reef ... for coral growth and production. Because they depend on light, coral reefs require clear water for growth and can be severely damaged by sediment or other factors that reduce water clarity or quality. Oth...

... reefs their apparent color. When bleaching takes place, the zooxanthellae is expelled by the reef, which makes the reef look white, like it has been bleached. Bleaching occurs when the coral reef feels as if it "under stress", the most common "stress" a coral can face is the rising of the water temperature although, there are a number of biotic and abiotic ... the oceans where the temperature rises. In 1992 there was a study conducted by artificial intelligence to mock the process of coral bleaching so scientist could further study this. These investigations have come to the conclusions...

... . Most are photosynthetic, but some require organic substances for growth and development. Most diatoms are brownish in color; they possess xanthoplasts which contain chlorophylls a and c, beta-carotene, xanthophylls, fucoxanthin, lutein, and diatoxanthin. The two major classes of diatoms are Coscinopiscophyceae (centric diatoms) and Bacillariophyceae (pennate or featherlike diatoms). The Coscinopiscophyceae have radial symmetry, ... the largest and most complex protists (Margulis 1998). About 4100 species are organized into 675 genera. Most red algae are marine, but some live in fresh w...
