Predicting sediment flow in coastal vegetation
Original story at MIT News Seagrass, kelp beds, mangroves, and other aquatic vegetation are often considered “ecosystem engineers” for their ability to essentially create their own habitats: Aquatic leaves and reeds slow the flow of water, encouraging sediments to settle nearby to form a foundation on which more plants can grow. Such underwater forests provide shelter to hundreds of ...

New technology for remotely mapping beaches
Science and industry will now be able to map beaches and sandbanks without getting any feet wet. This follows three years of collaborative research resulting in a new commercial licence between National Oceanography Centre (NOC) and Marlan Maritime Technologies to sell new coastal mapping technology. The depth and pattern of sediment on the floor of the intertidal zones changes daily, yet ...

Study predicts seabed response to climate change
The results of the five-year study predict potential high-risk areas due to seabed movement, erosion and changes in reef growth. According to CSIRO Wealth from Oceans Flagship project leader Dr Cedric Griffiths, the interaction between the ocean and the seabed is poorly understood. 'We have more information about the surfaces of the Moon and Mars than we do about the seabed surrounding ...

What Causes Pools below Waterfalls to Periodically Fill with Sediment?
Deep pools below waterfalls are popular recreational swimming spots, but sometimes they can be partially or completely filled with sediment. New research showed how and why pools at the base of waterfalls, known as plunge pools, go through natural cycles of sediment fill and evacuation. Beyond impacting your favorite swimming hole, plunge pools also serve important ecologic and geologic ...

SediMeters Can Save Corals from Dredging Spill
The ongoing dredging of Miami Harbor has caused siltation (the accumulation of sediments) on the coral reefs outside the harbor. In a settlement of a recent lawsuit, the contractor, U.S. Army Corps of Engineers (USACE), has agreed to pay $400,000 for moving corals out of the way. They are not using any instrument for measuring the sediment accumulation, even though such an instrument exists, is ...

How green is ethanol made from sugarcane?
A recent study has concluded that expanding the amount of land in Brazil used to grow sugarcane for ethanol could have serious environmental and social consequences. It could lead to more pressure on natural rainforest if sugarcane displaces other crops northwards, degraded soil and water supplies, and exploitation of workers in the industry. Brazil provides an important case-study for policy ...
