Latest Coastal geography Stories
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.
With ecotourism on the rise, determining what elements of a nature-based attraction are most appealing can have significant consequences financially and for raising awareness of conservation issues.
A team of scientists from the Universidad Carlos III of Madrid and the University of California - San Diego have created a static pipeline wave in a laboratory.
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.
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...
