Reef Check. The world's largest international coral reef monitoring program involving recreational divers and experienced marine scientists.

Reef Systems is a company situated in Tonsberg, Norway. The company was established during 2002 to deliver products which can improve the growth conditions for fish, shellfish and other forms of nature on the seabed and in freshwater. Hence, we deliver products which can enhance aquatic biodiversity. We also deliver products which hinder erosion and protect undersea pipes and cables. Together with national and international organizations, we aim at providing leading technical knowledge about the involved subjects.

The Coral Reefs of The Sea section offers information about the sea reef formations, as well different zones you will encounter in the sea. Additionally you can also take a look at digital maps from around the world, like the Great Barrier Reef. You'll discover great data on countries around the world, but also find hundreds of Coral Reef Pictures, taken from the NASA and JSC missions over the sea. Planning a trip it's a good place to begin.

The ZMT's activities include a continuing international research interest in tropical marine ecosystems, their resources and their vulnerability to environmental and climatic changes. They address the scientific issues related to the management of tropical coastal marine ecosystems and their resources and contribute to building global partnerships for research, education and training in the field. Through these activities, which are fully integrated into the Intergovernmental Oceanographic Commission's (IOC) Program TEMA (Training Education and Mutual Assistance), the ZMT continues to contribute to the goals set by the Agenda 21 of the United Nations Convention on Environment and Development (UNCED).

This "Research Unit" aims to quantify the role of some of the most important low- and high-latitude ocean gateways in changing the global thermohaline circulation (THC), climate, and the evolution of marine organisms. The gateway apertures, in turn, are controlled by (slow acting) local geodynamics and (fast acting) glacio-eustatic sea-level change.

The major goal of The Rutgers University Marine Field Station (RUMFS), and the parent institution, the Rutgers University Institute of Marine and Coastal Sciences (IMCS), is to create a corridor for research, from the upper reaches of the Mullica River drainage basin, down through the Great Bay estuary, to the inner continental shelf, where a Long-Term Ecosystem Observatory (LEO-15) at 15 m depth has been established.

This site contains information about the Biological Indicators Program in the Environmental Sciences Division (ESD) at Oak Ridge National Laboratory (ORNL). Biological indicators have been developed and applied at a variety of field sites in the eastern United States to assess and evaluate the effects that environmental stressors such as contaminants have on the health of aquatic organisms, populations, and communities.

The Reef Education Network (REN) is a fun and interactive way to learn about coral reefs like the Great Barrier Reef and the many creatures that live in, on and around them.

ReefGuardian's website is dedicated to helping people take action to protect coral reefs and their marine life.
