Removing Worst Water Weeds #8 :Sargassum with Weedoo Workboats
Nothing ruins a trip to the beach like having to navigate around or through piles of rotting seaweed to get to the water. This is why Sargassumhas earned a place on our list of the worst water weeds. This genus of macroalgae (seaweed), started making headlines back in 2015 when huge amounts of it started piling up and decaying on lovely Caribbean island beaches such as the Dominican Republic, ...

Ocean plastic recycling: can recycling industry innovations help?
Most of us have heard the unsettling estimation on the state of the ocean plastic crisis: by 2050, there may be more plastic than fish in our seas. Gathering and recycling plastic from the ocean is necessary to prevent further damage to the environment and wildlife. How did we end up with an ocean plastic crisis in the first place? And how could the plastic recycling industry and new recycling ...

Meteo Tsunami Measurement by Ocean Radar WERA
On May 29, 2017 a meteorological. 2m high tsunami hit the Dutch. coast. Serious injuries were. Avoided only because of the. timing – the wave hit beaches at about. 5:45am local time. Some 50km southwest of. Zandvoort, where the wave was observed,. there are two WERA (WavE RAdar) ocean. radar systems, at Monster and Ouddorp. (Figure 1). These systems are owned by. Rijkswaterstaat (part of ...

What is the Paris Climate Change agreement, and what could it mean for the world’s oceans?
Whilst the Paris Agreement has been praised for its progressive steps towards the unification of the world’s leaders in action against the negative result of anthropogenic activity on the climate, it has also been criticised for its failure to determine legally enforced action as opposed to ‘promises’.Following research which charts the potential impacts of climate change on the ...

How Tire Shredding Protects Wildlife
One of the most revolutionary inventions in the history of mankind was the wheel, and the best upgrade to that invention was the rubber tire, which overcame the limitations of wooden or metal wheels and made it possible to have smooth rides at fast speeds. However, there is a significant drawback to using rubber tires: eventually, they get too worn out to be useful as tires anymore and have to ...

Valuable met-ocean data for the Port of Rotterdam Real time current and wave data from HF Radar WERA
To fulfill its mission to “continually improve the Port of Rotterdam and to make it the safest, most efficient and most sustainable port in the world“, Rijkswaterstaat, part of the Ministry of Infrastructure and Environment, decided in 2014 to improve the quality and reliability of the ocean current forecasting. The forecasting is based on a hydrodynamic model operated by ...

Sea Level Rise: Risk and Resilience in Coastal Cities
Introduction One of the most dire impacts of anthropogenic climate change is a rise in the global sea level caused by the melting of glaciers and land-based ice caps, as well as a smaller increase from expansion due to the higher temperature of the water itself. Unlike some other predicted effects of climate change, this impact has already been observed for some time. Indeed, not only is there ...

Environmental impacts of ocean-energy systems: a life-cycle assessment
Ocean-energy technologies — which harvest renewable energy from the sea — will have a significant role to play in a future low-carbon society. A recent life-cycle analysis of different ocean-energy devices has found that life-cycle environmental impacts are caused mainly by the materials used in the mooring, foundations and structures. Improving the efficiency and lifespan of the ...

What will it take to get plastics out of the ocean?
From drones to filters to artificial islands, innovators are working to reduce the threat thousands of tons of trash pose to marine ecosystems. A few palm trees stand strong in the salty breeze. Located on the southern tip of the Pacific island chain of Hawaii, Kamilo Beach is an isolated stretch of black volcanic shoreline in the middle of nowhere. Just a few hundred yards from shore, humpback ...

NASA Science Zeros in on Ocean Rise: How Much? How Soon?
Seas around the world have risen an average of nearly 3 inches since 1992, with some locations rising more than 9 inches due to natural variation, according to the latest satellite measurements from NASA and its partners. An intensive research effort now underway, aided by NASA observations and analysis, points to an unavoidable rise of several feet in the future. Members of NASA's new ...

July is Lake & Reservoir Awareness Month!
Lakes and reservoirs cover over 40 million acres of the United States. Lakes and reservoirs also play other vital and often hidden, roles. They provide drinking water and irrigation water for agricultural fields and many times a source of electricity and power generation. They also serve an important function of absorbing rainfall and runoff from land, help to prevent floods, and provide homes ...

Living with floods in the Mahanadi Delta, India
In October 2013, one of the fiercest cyclones to hit the Bay of Bengal for many years made landfall on the low-lying delta coast of the Indian state of Odisha. With winds battering the coastline at more than 200 kilometres per hour, the structural damage from cyclone Phailin was intense. Thousands of straw, timber and bamboo homes were destroyed across the delta of the River Mahanadi, one of ...

Influence of wave and current flow on sediment-carrying capacity and sediment flux at the water–sediment interface
In nearshore waters, spatial and temporal scales of waves, tidal currents, and circulation patterns vary greatly. It is, therefore, difficult to combine these factors’ effects when trying to predict sediment transport processes. This paper proposes the concept of significant wave velocity, which combines the effects of waves, tides, and ocean currents using the horizontal kinetic energy ...

Marine litter – a growing threat worldwide
Increasing amounts of litter are ending up in the world’s oceans and harming the health of ecosystems, killing animals when they become trapped or swallow the litter. Human health is also at risk, as plastics may break down into smaller pieces that may subsequently end up in our food. These are just a few of the problems emerging from the waste collecting in our seas. There are now vast ...
