  • Distributed Thermal-Acoustic Data Integration

    Silixa has developed a technique called Distributed Thermal Acoustics (DTA) to monitor simultaneously the thermal and acoustic profile along a hybrid optical fibre cable in submarine environments. Using its world leading distributed fibre optic technology (ULTIMATM DTS and iDASTM) Silixa deployed an optical fibre cable along the seabed and across the water column in an active gas seepage ...

  • Time to stop losing ocean data to vandalism

    More must be done to prevent damage of ocean data buoys that costs money, vital data — and lives, say Sidney Thurston and M. Ravichandran. The global community relies on a rapidly expanding ocean observing network to understand the climate and ecosystems, to help warn against ocean-borne hazards such as tsunamis and storm surges caused by cyclones, and to support sea rescue ...

  • Two innovative devices for depth sampling in granular filtration systems. Desalination 286: 115–119, 2012.

    Appropriate devices for obtaining either interstitial water or grain particle samples or for measuring dissolved oxygen (DO) at depth within the interior of large-scale, industrial granular bed filters are currently lacking. We developed two innovative samplers for studying a Rapid Sand Filter (RSF) at an operational SWRO plant: the first for water and granular material, the second ...

  • Application of hybrid Kalman filter for improving water level forecast

    Numerical modeling is one of the popular means to simulate and forecast the state of oceanographic systems. However, it still suffers from some limitations, e.g., parameter uncertainties, simplification of model assumptions, and absence of data for proper boundary and initial conditions. This paper proposes a hybrid data assimilation scheme, which combines the Kalman filter (KF) with a ...

  • Advanced offshore measurements to support wind energy production, weather forecasting, and emergency response

    Sonoma Technology, Inc. (STI), with support from the Bureau of Ocean Energy Management, is leading a unique partnership of corporate, government, and university researchers to develop a marine environmental observations program in the Gulf of Mexico. The primary goal of this project is to develop a framework of advanced offshore measurements to support emergency response, oil and gas exploration ...

  • Interviews: Ken Buesseler, Researcher into marine discharges at Fukushima

    We as scientists do have a responsibility and I hope to be able to contribute in some way“ Ken Buesseler, researcher at the Wood Hoods Oceanographic Institute is investigating the radioactivity leaked from the Fukushima nuclear power station, initially from data facilitated by the TEPCO (Tokyo Electric Power Company) and then from samples gathered in situ. He believes that official bodies ...

  • Marine Sciences Investigations in Support of Level Oftreatment Decisions for Municipal Wastewater Discharges in Puerto Rico

    ABSTRACT The Puerto Rico Aqueduct and Sewer Authority (PRASA) currently has National Pollutant Discharge Elimination System (NPDES) permits that incorporate relaxation (waiver) of BOD and TSS secondary treatment requirements for six of its regional wastewater treatment plants. The waivers are available under Section 301(h) of the Clean Water Act. Maintaining the waivers requires, in part, ...

  • 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 ...

  • Trelleborg Harbour Marine helps moor vessels safely at LNG terminals

    Trelleborg Harbour Marine helps moor vessels safely at LNG terminalsSafety is the priority at LNG terminals, which are growing in number inline with an increased demand for the fuel. Like many fuels, LNG is potentially hazardous and to help reduce the possibility of an incident during berthing or when a vessel is alongside a jetty, integrated mooring systems are becoming standard specification. ...


  • New monitoring technology helps reveal Arctic secrets

    A group of Arctic researchers has employed the latest monitoring technology to investigate the effects of climate change, by measuring temperature and salinity in the water column beneath surface ice. The results of the investigation, which utilised YSI’s new 'Castaway-CTD', could cast new light on our understanding of the ways in which shifting ocean currents impact upon the climate in ...

  • 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 ...

  • Harnessing The Power Of Microbes

    University researchers are advancing both the understanding and scalability of a biological process where bacteria living under anaerobic conditions consume organic waste and generate electrons and protons that are tapped for electricity production.IMAGINE a self-sustaining battery that never runs out of juice. While the notion may sound far-fetched, Dr. Leonard Tender at the Naval Research ...

  • Eco-Industrial Development: The case of the United States

    Issue: Businesses, local government and community groups are all seeking new answers for how to assure greater compatibility between environmental and economic opportunities. One possible contribution to meeting this challenge is a new phenomenon capturing the imagination of those concerned with responsible economic development in the United States. This phenomenon is known by various names, ...


  • 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 ...
