  • Water Pollution

    Water pollution is a major global problem that requires ongoing evaluation and revision of water resource policy at all levels (from international down to individual aquifers and wells). It has been suggested that it is the leading worldwide cause of deaths and diseases, and that it accounts for the deaths of more than 14,000 people daily. In addition to the acute problems of water pollution in ...

  • 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 ...

  • Ocean Thermal Energy and Water Production

    Introduction The scarcity of potable water is a growing problem worldwide, particularly in arid regions and among developing countries. Compounding this problem is the increasing contamination of freshwater sources, which comprise only about 2.5% of all water on Earth. Of this small portion, only 0.5% of the total fresh water available is found in easily accessible sources such as ...

  • How to investigate mercury in the oceans?

    Mercury is a highly toxic metal that affects the environment and can endanger people's health, as a powerful neurotoxin. The combustion of coal, waste and fuel are releasing hundreds of tons of heavy metal into the atmosphere annually, and its sediment enters to soil and water. Mercury measurements are part of the EU project "Global Mercury Observation System". The long-term goal of this ...

  • Worldwide Coastal and Oceans Woes Continue.

    'The oceans are in trouble and so are we,' oceanographer Sylvia Earle, National Geographic explorer in residence and researcher for the Smithsonian, was quoted as saying in an article on the web by Seth Borenstein writing for the Philadelphia Inquirer and San Jose Mercury News Washington Bureaus. Citing a study by the Harvard Medical School's Center for Health and the Global Environment covering ...


  • Shellfisheries: Time to prepare for ocean acidification

    Both physical and social factors must be considered as coastal communities brace for an uncertain future. Oceans are gradually becoming warmer and more acidic as more carbon dioxide enters the atmosphere — two shifts that are altering the economic foundations of many coastal regions. In a ...

  • 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 ...

  • Ocean science for sustainable development: Facts and figures

    Sarah Grimes explores why we need good ocean monitoring, how to get it, and why it still fails Small Island Developing States. Oceans are a critically important component of the Earth system, supporting ecosystem and human health. They regulate the weather and climate; are essential for producing freshwater; and soak up ...

  • In the depths of the oceans, human activities are beginning to take their toll

    Once seen as too remote to harm, the deep sea is facing new pressures from mining, pollution, overfishing and more. Imagine sinking into the deepest parts of the Central Pacific Ocean, somewhere between Mexico and Hawaii. Watch as the water turns from clear to blue to dark blue to black. And then continue on for another 15,000 feet (4,600 meters) to the seafloor — roughly the ...

  • Surface Ocean Acidification studies using Ships Of Opportunity

    Ships of Opportunity Ships of opportunity (SOOP) are used as a platform for cost-efficient collection of environmental data, Ferrybox. The SOOP network operated by NIVA cover the majority of the Norwegian coastline (from Germany (54N ) in the South to Svalbard (78N) in the North. This network is used in the national OA monitoring program. Globally, SOOPs are used for pCO2 measurements and ...

  • “We continue to be stunned at how rapidly the ocean is warming.”

    Oceans have been absorbing more of global warming’s heat and energy than would normally be expected, helping to slow rates of warming on land. But how long will that last? Probing a blue abyss can be an abysmal recipe for the blues. For every 10 joules of energy that our greenhouse gas pollution traps here on Earth, about 9 of them end up in an ocean. ...

  • Why Pacific islands should take on ocean monitoring

    Pacific islands must build capacity for their own environmental monitoring to tackle both local and global problems, says Ben Ponia. Small island developing states are viewed as the early-warning canary for global environmental change. But though they share global problems, many have an eye for economic growth and have become industrialised nations facing their own suite of home-grown ...

    Levels began to climb in the 1970s, peaking a decade ago — a timeline consistent with the region’s pattern of leaded gasoline use. Written by Jennifer Chu, MIT News Office.You can read the original new in MIT NewsSince the 1970s, leaded gasoline has been slowly phased out ...

  • The number one thing we can do to protect Earth’s oceans

    Marine governance favors consumption and commerce over conservation. Here's what we can do about it. When New England fishers complained of working harder and harder to catch fewer and fewer fish, Spencer Baird assembled a scientific team to investigate. Though a fishery failure would once have seemed inconceivable, Baird wrote in his report, “an alarming decrease of the ...

  • How listening to the ocean can help reveal environmental damage

    In 2013, Katherine Indeck listened to recordings of sounds made in a channel between the Gulf of Mexico and Tampa Bay, Florida. Some of the audio files had been collected in 2005 during an unusually severe red tide, a bloom of toxic algae that killed fish, dolphins and sea turtles. Other recordings were made after the ecosystem began to recover. During the recovery years, Indeck could hear sounds ...

  • Customer Diversification is Key to Marketing of Biosolid Product for Ocean County, New Jersey

    ABSTRACT In the United States, most public wastewater treatment agencies with beneficial-use biosolids management programs utilize Class B biosolids. Many of these agencies have concerns about their Class B programs, and therefore, are examining Class A treatment processes. Within the family of Class A technologies, thermal drying is one of the fastest growing management methods. A critical ...

  • Satellite ocean color observations of stormwater runoff plumes alongthe San Pedro Shelf (southern California) during 1997–2003

    Knowledge of freshwater runoff plume dynamics in southern California is important for management of coastal water quality, because river discharge associated with episodic winter rainstorms can be a major source of pollutants and pathogens to coastal waters. The purpose of this study was to analyze the spatio-temporal dynamics of plumes at the San Pedro Shelf in southern California and identify ...

  • The economics of pollution trading and pricing under regulatory uncertainty

    From the world's highest mountain ranges to the lowland plains, and from the great oceans and coastal wetlands to agricultural landscapes, nations and communities rely on the bounty and services of natural ecosystems. Biological resources and the goods and ecosystem services they provide underpin every aspect of human life and livelihoods, from food and water security to general well-being and ...
