  • 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 ...

  • 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 ...

  • 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 ...

  • 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 ...

  • 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 ...

  • 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 ...

  • “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. ...

    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 ...

  • 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 effects of mining pollution on subtidal habitats of northern Chile

    Mining is the most important commercial activity in Chile, producing more than 60% of the total national income. In northern Chile, where mining extraction is concentrated, solid and liquid pollutants resulting form copper and iron ore processing are discharged to the ocean. The studies on the effects of mining on coastal marine environments in Chile mainly consist of the evaluation of heavy ...

  • Marine specimen banking: archive and pollution control for the 21st century

    The oceans have in the past been extensively used as disposal sites for various kinds of waste. The world ocean – being the final sink for many natural and anthropogenic substances – is a "labile" ecosystem, which is and has for a long time been the focal point of extensive interdisciplinary research. Measurements of heavy metals and a suite of various chemical compounds in the marine ...

  • Tracking biological pollution sources using PCR-DGGE technology at Ta-An Beach

    The environmental authority of Taiwan has announced that ocean quality standard A, with E. coli less than 1,000 CFU/100 mL is safe for swimming. Ta-An Beach in central Taiwan was found to have exceeded 1,000 CFU/100 mL, which is 51% of the total monitoring records. Sewage, piggery and duck wastewater are discharged directly into this area. The traditional pollution source trace methods did not ...
