  • Comparison of Directional WaveGuide Radar with Directional WaveRider Buoy

    Abstract Down looking FMCW radars for measuring water level, tides and wave height have been in use for 25 years. A combination of three down looking FMCW radars, mounted on an o↵ shore location, can be used to accurately measure ocean wave height and wave direction. At locations where an o↵shore mounting construction is readily available, the major advantage of this relatively ...

  • 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 ...

  • BREEZE Met Data Facilitates Long Range Dispersion Modeling

    U.S. EPA requires that facilities located within 200 km of Class I areas or others with visibility degradation issues conduct long-range dispersion modeling studies. CALPUFF, an EPA-approved model for long-range transport modeling, is a non-Gaussian, non-steady state, puff model that operates in a Lagrangian framework, unlike the Eulerian approach used by Gaussian dispersion models. The extensive ...

  • Water quality in the Arosa Bay

    Background One of the great impediments to further development of shellfish aquaculture in the north-west region of Spain isa perception that industry expansion and tourism could have negative environmental effects on the coastal waters. Especially the bay around Villagarcia de Arosa is very famous because of its excellent areas for shellfish farming. The government of Spain is ...

  • Case study - Algae control in East Dorset raw water reservoir

    Bournemouth Water has installed four MPC-Buoy systems to monitor and control algal blooms at Longham Lakes. After the installation of the MPC-Buoy systems a dramatic reduction in the concentration of algae was experienced. The Challenge: Installing an Environmentally Friendly Solution to Control Algal Blooms The objective of the project was to reduce algae concentrations . ...

  • Hybrid wavelet-GMDH model to forecast significant wave height

    In this study, the group method of data handling (GMDH)-based wavelet transform (WT) was developed to forecast significant wave height (SWH) in different lead times. The SWH dataset was collected from a buoy station located in the North Atlantic Ocean. For this purpose, the time series of SWH was decomposed into some subseries using WT and then decomposed time series were imported to the GMDH ...

  • WRF evaluation exercise using open sea in situ measurements

    This work regards a model evaluation exercise concerning the WRF meteorological model and in situ measurements collected both over land, at four WMO meteorological stations, and over open sea, by ODAS Italia 1, the only spar buoy in the Mediterranean Sea. In particular, this exercise is finalised to understand the ability of the model to act as meteorological pre–processor to simulate aerosol ...

  • Map Algal Blooms with Satellite Remote Sensing Technology

    The quality of water bodies is a key determinant in the usability of the resource for the purpose required. It is therefore of great importance to managers of hydrologic resources to be able to confidently tell the status of their water resource. One of the major problems in the quality of surface water bodies is the blooming of algae and blue green algae. Algal blooms can result in ecological, ...

  • Water quality is key to the success of Cardiff Bay

    Water quality has been a central theme in a redevelopment project that began with the creation of the Cardiff Bay Development Corporation in April 1987. This article will examine the role that water quality has played in the remarkable transformation that has taken place in Cardiff and explain how monitoring technology has developed to the stage whereby any person, anywhere in the world, can view ...

  • Intercomparison of a WaveGuide radar and two Directional Waveriders

    Down-looking FMCW radars for wave measurements are in use already for 25 years. They have proved to be very robust and maintenance is hardly needed. Now the prices of FMCW radars came down they are being more widely applied for water level, tide, harbour oscillations and wave height at sea, lakes and rivers. Radacs WaveGuide was introduced in 1998 based upon a commercial tank radar, first Enrafs ...

  • Measuring Offshore Wind Resources

    To select the right offshore wind site, estimate the future energy output of a wind farm, and determine the best layout for the turbines, project developers must conduct wind resource assessment (WRA) campaigns on site. This is a critical phase of the successful development of wind farms. WRA campaigns on terrestrial sites have traditionally been performed using meteorological towers equipped ...

  • Below the Waterline: Leading Indicators of Safety Performance

    Getting a measure of injuries, incidents, and near misses can tell leaders a lot about the state of safety in the organization. How and where people are getting hurt provides valuable insight that can be used to remove hazards and protect against at-risk behavior. As important as injury reporting is, however, it's only the tip of the iceberg. Below the waterline is the vast bulk of injury ...

  • Modeling emissions from offshore drilling

    To regulate drilling activities proposed by oil and gas companies in the oil-rich Gulf of Mexico (GOM), governing agencies require the submittal and approval of certain plan documents before drilling activities can be initiated. For drilling activities in the Western GOM, these plans typically consist of one of the following: EP, or Exploration Plan – required to conduct ...

  • Managing oceans with sound science

    Management of marine resources for sustainable development needs local capacity for science, particularly in the Pacific region. Those who care about environmental damage and its effects on the health and welfare of communities tend to focus on land-based threats. That is where harm can be most easily observed, and where its causes — from agricultural pesticides to industrial air ...

  • 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 ...

  • REACH Heads Back to the Drawing Board

    The European Commission's proposals for reforming the EU's chemicals policy with its so-called REACH regime have created the biggest storm in over 30 years of EU environmental policy. The internet consultation on its draft legislative proposals attracted some 7,000 responses over the summer - and provoked a high-level political backlash which has thrown them back into the melting-pot. Since the ...

  • Oceans of Energy

    Technologies that harness the energy of moving water or temperature differentials in the oceans promise to deliver abundant carbon-free electricity. Long before humans got hooked on fossil fuels, we learned how to harness the power of water to do work. Rivers ran mills that ground flour, sawed logs or spun looms that transformed fibers into textiles. Later generations realized that moving water ...
