New evidence shows that a chemical produced by corals can affect local climate patterns.
An aeronautics engineer and marine biologist have teamed up to use an unmanned drone and cutting-edge computer software to map and measure centuries-old corals.
Natural reefs are being decimated by mankind and artificial reefs are becoming a viable alternative. (PRWEB) October 05, 2013 Reefs are a wellspring
The continued accumulation of sand within the iconic ring-shaped reefs inside Maldivian atolls could provide a foundation for future island development new research suggests.
New research indicates that crustacean populations living near rapidly declining coral reef habitats could be at risk.
Toxic metals from the only open pit mine in an estuary system in the United States are widespread in nearby sediment, water and fish and may be affecting marine and coastal animals that feed on them beyond the mine site
Deep ocean waves play a vital role in long-term climate cycles and a new study from scientists at the University of Washington has revealed waves the height of skyscrapers circulating energy and nutrients deep below the Southern Pacific Ocean.
Major weather events can shock an ecosystem, but they are also part of Earth’s natural cycle, and many species are adept at recovering from an environmental shake up.
After examining other influences on shoreline change including waves, sediment supply and littoral processes, and anthropogenic changes, the best explanation for the difference in island-wide shoreline trends, such as beach erosion or accretion, is the differing rates of relative sea-level rise on Hawaiian islands.
A new computer simulation conducted at the University of Bristol (UB) and University of Miami (UM) Rosenstiel School of Marine & Atmospheric Science has revealed the epic, ocean-spanning journeys traveled by millimetre-sized coral larvae through the world's seas.
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, 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...
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...
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...
