  • Handling of a large dataset: application of Time Series Analysis to oceanographic studies

    This paper describes the application of the specific Time Series Analysis techniques (TSA), Autocorrelation analysis (AC), Crosscorrelation analysis (CC) and Power Spectral Density (PSD) to elaborate a large set of oceanographic data, such as marine pressure, flow and current. The data were collected by ad hoc oceanographic instrumentations in two different sites of the Italian seas as digitised ...

  • Ocean outfall plume characterization using an autonomous underwater vehicle

    A monitoring mission to map and characterize the Point Loma Ocean Outfall (PLOO) wastewater plume using an Autonomous Underwater Vehicle (AUV) was performed on 3 March 2011. The mobility of an AUV provides a significant advantage in surveying discharge plumes over traditional cast-based methods, and when combined with optical and oceanographic sensors, provides a capability for both detecting ...

  • Coastal Resources Exploitation can Mask Bottom–up Mesoscale Regulation of Intertidal Populations

    We describe the spatial distribution patterns of rocky intertidal Patella spp. limpets (heavily collected by shellfishers) and top-shell snails belonging to the genus Osilinus (comparatively slightly harvested) through a multiscaled sampling design spanning five orders of magnitude of spatial variability (from 10s of m to 100s of km) throughout the Canarian Archipelago (eastern Atlantic); where ...

  • 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 hydrogeology: recent accomplishments and future opportunities

    Marine hydrogeology is a broad-ranging scientific discipline involving the exploration of fluid–rock interactions below the seafloor. Studies have been conducted at seafloor spreading centers, mid-plate locations, and in plate- and continental-margin environments. Although many seafloor locations are remote, there are aspects of marine systems that make them uniquely suited for hydrologic ...

  • Use of marine outfalls in wastewater disposal

    Global experience has shown that disposing of properly treated domestic wastewater through effective ocean outfalls is an economical and reliable strategy for wastewater disposal with minimal environmental impact. Better construction techniques, such as tunnelling, coupled with improved materials mean that the technology of marine wastewater disposal has advanced rapidly in recent years. ...

  • 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 ...

  • 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 ...

  • Long-term changes in the northern Adriatic ecosystem related to anthropogenic eutrophication

    Knowledge of the mechanisms driving long-term changes in the nutrient and primary production cycles represents a basic step to verify real eutrophication trends in shallow marine ecosystems, such as the northern Adriatic open waters. In fact, this ecosystem appears to be especially sensitive to seasonal and long-term variations of the anthropogenic nutrient load (primarily the Po River ...

  • Transparent exopolymer particles: Potential agents for organic fouling and biofilm formation in desalination and water treatment plants

    Transparent exopolymer particles (TEP) are ubiquitous in marine and freshwaters, and have been subject to intensive study by oceanographers and limnologists over the past 15 years. These microscopic organic particles (visualized by Alcian Blue staining for acid polysaccharides) may be considered a planktonic form of exopolymeric substances (EPS). Two aspects relating to the potential involvement ...

  • Eonfusion: The next generation of geospatial software

    In modern time, the ability to explore the oceans has been inextricably linked to the evolution and development of marine technology. Over the past 20 years, the steady evolution of hardware design has resulted in increased sampling rates, data volumes and resolutions. Furthermore, improvements in the manufacturing of marine technology have decreased the overall cost of hardware which has ...

  • A Sound Projector for Acoustic Tomography and Global Ocean Monitoring

    Abstract—Long-range underwater acoustic systems, such as those used in ocean acoustic tomography, require low-frequency signals covering a broad frequency band. To meet this requirement, a novel design based on of a tunable narrow-band high-efficiency sound projector has been exploited. The projector transmits a frequency sweep signal by mechanically tuning a resonator tube (or organ pipe) ...

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