The Conservancy is highlighting the benefits of coral, mangrove, sea grass, and shellfish restoration to people and nature including reducing risk from natural disasters for coastal communities

Volcanoes Responsible For Coral Reef Diversity
2013-05-22 10:25:08

A new study claims earthquakes and volcanoes are responsible for the diverse nature of the ocean’s coral reefs. With this information, scientists are now becoming even more worried about global warming.

New Study On Coral Reef Formations Lays To Rest Conflicting Theories
2013-05-14 07:53:01

The mechanism underlying three unique reef formations and how they developed over evolutionary time has produced an enduring debate between two hypotheses – the first from English naturalist Charles Darwin and the second from geologist Reginald Daly. A new study has put an end to both conflicting theories.

Coral Reefs Still In Danger But Demise Not Inevitable
2013-05-10 10:20:05

Although scientists agree that coral reefs are in danger, a new study shows that the collapse of such reefs can still be avoided with a combination of local and global action.

Coral Bleaching Study Explains Different Responses To Climate Change
2013-04-24 12:24:35

As a changing climate threatens to bleach the corals of the world’s oceans on a massive scale, a team of researchers has discovered why some corals respond differently to bleaching than others.

Scientists Say More Large Ocean Wilderness Parks Needed

Leading international marine scientists have called for the protection of more, large marine wilderness areas in a bid to shield the world’s dwindling stocks of fish from destruction.

Picky Eaters Keep Endangered Coral Reefs Clean

A recent study conducted in the Fiji Islands found that four species of herbivorous fish were primarily responsible for removing common and even potentially harmful seaweeds on reefs.

According to a new technical report, the effects of climate change will continue to threaten the health and vitality of U.S. coastal communities' social, economic and natural systems.

Investigating How Corals Survive In The Hottest Reefs On The Planet
2013-02-01 14:48:45

Coral reefs are predicted to decline under the pressure of global warming. However, a number of coral species can survive at seawater temperatures even higher than predicted for the tropics during the next century.

Cape Cods Salt Marshes Are Under Threat

Coral Reef
2013-04-20 15:49:21

Coral reefs are submerged structures consisting of calcium carbonate secreted by corals. Coral reefs are colonies of small animals found in marine waters that enclose few nutrients. The majority of coral reefs are constructed from stony corals, which then consist of polyps that come together in groups. The polyps are like small sea anemones, to which they are very closely related. Unlike the sea anemones, coral polyps secrete hard carbonate exoskeletons which provide support and protections...

Mudflats
2013-04-19 21:07:34

Mudflats, or otherwise known as tidal flats, are coastal wetlands that form when mud is left behind by tides or rivers. They’re found in sheltered regions such as bayous, lagoons, estuaries, and bays. Mudflats might be seen geologically as exposed layers of bay mud, a result from the deposition of estuarine silts, marine animal detritus, and clays. The majority of the sediment in a mudflat is within the intertidal zone, therefore the flat is submerged and exposed about twice per day. In...

Salt Marsh
2013-04-19 21:04:15

A salt marsh, also otherwise known as a coastal salt marsh or a tidal marsh, is a coastal ecosystem in the upper coastal intertidal zone that lies between the land and the open salt water or brackish water that is routinely flooded by the tides. It’s dominated by dense stands of salt-tolerant plants, for example, herbs, grasses, or low shrubs. These plants originate from all around the globe and are important to the stability of the salt marsh in trapping and binding sediments. Salt marshes...

Basic Ocean Terms
2013-02-05 12:52:11

Image Credit: Meteorologist Joshua Kelly When meteorologists are forecasting for ocean-going vessels, there are a few terms that we need to understand. The first term is wavelength. Wavelength is defined as the distance between two crests or between two troughs as seen in the image above. The example above highlights the crest to crest concept of wavelength. The next term that we use is wave height, and to determine this, we first must look at the wave when it passes our station. When...
