  • 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 ...

  • Canarina DESCAR software · ocean pollution modeling · algorithms 4

    We attempt to link the momentum dominated and buoyanvy dominated regimes into one relationship by using proposed relations for the transition where:   z/Lb =24/3[(1/2)(x/Lb)2+(Lm/Lb)(x/Lb)]1/3      ...

  • Impact of surface ocean acidification on the CO2 absorption rate

    The rising level of atmospheric CO2 and consequently the acidification of the surface ocean affect the CO2 absorption rate. However, there are no mathematical models to describe the impacts of acidification on the rate of CO2 absorption. Therefore, ...

  • Similarity theory and parameterization of mixing in the upper ocean

    Boundary layers with small thermal and mechanical inertia are close to steady-state conditions. This underlies the Monin-Obukhov similarity theory and explains why the surface values of the fluxes can be chosen as external parameters. For fluids with large thermal inertia, such as the ocean, the thermal time scale is relatively large, and the density flux is a complex function of depth, thus, the ...

  • Seeding the oceans may not stop climate change

    Geo-engineering against climate change – Seeding the oceans with iron may not address carbon emissions Numerous geo-engineering schemes have been suggested as possible ways to reduce levels of the greenhouse gas carbon dioxide in the atmosphere and so reduce the risk of global warming and climate change. One such technology involves dispersing large quantities of iron salts in the oceans to ...

  • 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 ...

  • “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. ...

  • Ships that harvest electrical power from ocean waves

    Electrical power generation from ocean waves is possible from ships that harvests wave energy through daily trips to offshore locations and that return back to port for the delivery of energy to the grid. Energy is stored locally on the vessel during harvesting phase and placed on the grid during periods of high demand (normally mid-day). Unlike conventional wave-power devices, the ships ...

  • 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 ...

  • Simulating the Holocene climate evolution at northern high latitudes using a coupled atmosphere-sea ice-ocean-vegetation model

    The response of the climate at high northern latitudes to slowly changing external forcings was studied in a 9,000-year long simulation with the coupled atmosphere-sea ice-ocean-vegetation model ECBilt-CLIO-VECODE. Only long-term changes in insolation and atmospheric CO2 and CH4 content were prescribed. The experiment reveals an early optimum (9–8 kyr BP) in most regions, followed by a 1–3°C ...

  • Overview of Infrastructure Asset Management A View from Both Sides of the Atlantic Ocean

    AbstractEurope and the United Kingdom (UK) are at the forefront of Asset Management for water utilities. This is primarily due to the fact of privatization of water utilities in the UK. The UK is currently in the third generation of the Asset Management procedures and has well defined methods for identifying and managing assets. In the United Kingdom (UK), large scale Asset Management has been ...

  • 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 ...

  • A small island in the Indian Ocean offers big lessons on clean power

    The Indonesian island Sumba is working to provide 100% renewable electricity to all 650,000 residents by 2025. As the sun sets on the small Indonesian island of Sumba, Danga Beru Haba begins weaving under the glow of a single incandescent lightbulb, the only one in her home. Although she is tired from working dawn to dusk in the fields surrounding her village of ...

  • Nutrient dynamics in European water systems - the management perspective emerging from ELOISE, a European cluster of land - ocean interaction studies

    The European ELOISE (European Land Ocean Interaction Studies) cluster (>60 projects) is the world's largest research initiative on land - ocean interactions. Beside its scientific goals, ELOISE is also meant to contribute directly to coastal zone management and thus to European coastal policy. Most of the ELOISE results have been gathered in digests that are made available on the Internet to all ...

  • Three models of social change

    Can we change fast enough? When thinking about the enormous need for social change as we attempt to move the world economy onto a sustainable path, I find it useful to look at various models of change. Three stand out. One is the catastrophic event model, which I call the Pearl Harbor model, where a dramatic event fundamentally changes how we think and behave. The second model is one where a ...

  • Potential Dispersion Modeling Uses of Archived NOAA Forecast Model Data

    A newly-developed generation of air quality simulation models has the potential to use profiles of wind, temperature, and turbulence, as well as improved mixing height determination, measures of surface heat flux, and a host of other meteorological parameters. Several numerical weather prediction models that generate these comprehensive data sets are routinely being run by the National Oceanic ...

  • 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 ...
