Latest Coastal geography Stories
Now more than a year out from Superstorm Sandy, a University of Texas led research team has good news for the region.
Millions of people across the world live or depend on deltas for their livelihoods.
Scientists have believed for years that preserving more species, no matter which ones, was a key component to enhancing how well an ecosystem performs. However, researchers investigating biodiversity loss in a salt marsh says that this isn't quite right.
In the first global assessment of its kind, a science team led by researchers at Scripps Institution of Oceanography at UC San Diego has produced a landmark report on the impact of fishing on a group of fish known to protect the health of coral reefs.
Left to themselves, coastal wetlands can resist rapid levels of sea-level rise. But humans could be sabotaging some of their best defenses
A new study on coral reefs from a team of Florida and Oregon researchers has found common marine pollution doubled the rate of disease among corals and more than tripled the amount of coral bleaching, an early sign of reef stress.
A new study reveals that global changes in climate and ocean chemistry affect corals whether scarce or abundant, and often it is the dominant, abundant corals with wide distributions that are affected the most.
A new study from the National Oceanic and Atmospheric Administration (NOAA) and its academic partners reveals that coral reefs may be able to adapt to moderate climate warming, improving their chance of surviving through the end of this century.
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...
