The impact of ocean acidification on coral reefs
By: Jose Juan Gutierrez
Coral reefs are one of the most diverse marine ecosystems of the world. The coral reef ecosystem is formed by the calcifying organisms inhabiting it, such as corals and algae. Even though, coral reefs occupy a small percentage (0.1%) of the ocean, they...
Anthropogenic threats to coral reefs
By: Jose Juan Gutierrez
Coral reefs are one of the most diverse marine habitats in the world. The coral reef ecosystem is sometimes dubbed as the marine rain forest for its wide variety of marine life. It has been estimated that the coral reef ecosystem is the habitat of...

There is so much water on Earth compared to land (71 percent of the surface) that many prefer to call it the "water planet," and some are even of the opinion that "earth" is a misnomer. The presence of so much water, all in...
How do coral reefs form?
By: Jose Juan Gutierrez
Coral reefs are marine structures made of calcium carbonate (CaCO3) secreted by stony corals and other marine species living in the reef. Corals are colonial organisms composed of hundreds of thousands of individual animals known as polyps, which cluster in groups. Polyps secrete calcium carbonate...

The German ship Meteor accomplished a three-year mission of measuring the depths of the South Atlantic Ocean in 1927. Their assumption was that the level of the ocean was uniform, and so depth measured only one thing-how deep the ocean floor was from "sea level...

The thermohaline circulation (Great Ocean Conveyor) in the ocean is the flow of surface and deep ocean water currents driven by temperature and density differences. The density of sea water depends on variations in temperature and salinity. Fresh water fluxes coming from rain, ice-melt and...
Facts about marine sediments: Turbidites
By: Kimberly Napier
Turbidites are sea deposits which are formed by underwater avalanches. They are responsible for large amounts of clastic sediment in the ocean. Formation Turbidites travel and are deposited by density flow, or gravity currents. Usually, in a river bed, rock is carried by a frictional...
By: Zacharie King
Turbidites are sedimentary deposits laid down by underwater landslides. Course sediment is carried far away from shorelines where they are later deposited. As a result these deposits disrupt the natural sedimentary processes that normally exist. Areas that see most of this activity occurs along fault...

One of the most difficult environments for geologist to gather samples of rock and study geological features are the ocean floors. The vastness of the ocean in addition to the immense pressure makes traditional methods of collecting samples and viewing features nearly impossible. To combat...
The effects of overfishing on coral reefs
By: Jose Juan Gutierrez
Coral reefs are marine ecosystems that are important for recreational, tourism, commercial, and fishery industries around the world. Diverse plants and marine animals in the coral reef ecosystem provide a rich resource from where scientists obtain natural products to treat a wide variety of diseases...
