Latest Coastal geography Stories
Two types of small beach critters –– both cousins of the beloved, backyard roly-poly –– are suffering localized extinctions in Southern California at an alarming rate, says a new study by UC Santa Barbara scientists.
A new study shows that natural habitats such as dunes and reefs are critical to protecting millions of US residents and billions of dollars in property from coastal storms.
Researchers discover a long-forgotten seawall buried on the shores of New Jersey that helped to protect the coast from the full wrath of Hurricane Sandy.
Many biological processes have their roots in the very earliest stages of life’s evolutionary tree, and new research indicates that part of our immune system may come from coral-like ancestors.
A contentious debate is stirring in the Aloha State between fishermen and those looking to preserve species living in the regions’ coral reefs.
Researchers wrote in the journal Environmental Research Letters that all existing coral reefs will die from inhospitable ocean chemistry conditions by the end of the century if civilization continues on its current path.
The corals reefs on Australia’s Great Barrier Reef were devastated by Cyclone Yasi – a Category 5 Hurricane which made landfall in Queensland, Australia, on February 3, 2011.
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
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.
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 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...
