  • Ocean carbon: A dent in the iron hypothesis

    Oceanographers Jim Bishop and Todd Wood of the U.S. Department of Energy’s Lawrence Berkeley National Laboratory have measured the fate of carbon particles originating in plankton blooms in the Southern Ocean, using data that deep-diving Carbon Explorer floats collected around the clock for well over a year. Their study reveals that most of the carbon from lush plankton blooms never reaches the ...

  • Ocean acidification investigations in the Kiel Fjord

    Continuous, reliableand direct pCO2measurements since 2012 Greenhouse gases, and in particular carbon dioxide (CO2), are one of the most discussed topics in society today, influencing political debate, legal framework and business decision-making. From a pre-industrial 280ppm, atmospheric CO2 has risen to a present-day level of 390ppm, with this figure expected to rise to up to 1000ppm by the ...

  • Acceptance angle effects on the beam attenuation in the ocean

    Abstract The beam attenuation serves as a proxy for particulate matter and is a key parameter in visibility algorithms for the aquatic environment. It is well known, however, that the beam attenuation is a function of the acceptance angle of the transmissometer used to measure it. Here we compare eight different transmisso meters with four different acceptance angles using four ...

  • Is pH a red herring when it comes to ocean acidification?

    New research points to saturation state, not pH, as the most pressing metric to track when it comes to shellfish survival. In 2007, the owners of Whiskey Creek oyster hatchery on the Oregon coast lost almost all of their larvae — and had no idea why. The only clue was that the larval die-offs often occurred during intense upwelling events, when ...

  • 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 ...

  • 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 ...

  • Rainy Day Session Instruments

    Rainy Day Session Instruments Rain and melted snow in the United States winter can cause runoff.  Such winter runoff causes the movement of soil or at least cloudy turbid water. This had been known to occur on native undisturbed lands. However, with the growth of the population, we see more and more development ...

  • 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 ...

  • Measuring carbon dioxide (CO2) along ocean surfaces case study

    Customer: Confidential Application: A research team needed to study the levels and variations of one of the major greenhouse gases, carbon dioxide (CO2) along the ocean surfaces. The research team required CO2 analysers to be installed in commercial ocean liners to monitor the “dry” level of ...

  • Hydraulic Fracturing and the Environment Whitepaper - Analytical and Measuring Instruments

    The recovery of natural gas and oil from untraditional wells is necessary for the economic stability of the United States. Shale gas deposits are deep below the earth’s surface and recovery of gas is expensive and requires millions of gallons of water mixed with chemicals, known as "fracking solution". Most fracking solution stays underground or returns to the surface mixed with formation ...

  • New oil spill response application note from China

    The Problem: Oil may spill out in the process of oil exploration & development, refining, storage and transportation and enter into open water environment like oceanic environment due to incident or incorrect operation. Oil spill damages include to human heath, safety, ecological environment, aquaculture. In China, the State Oceanic Administration requires the oil content in the discharge to ...

  • Automated techniques for real-time shipboard determination of dissolved trace metals in marine surface waters

    This review compares methods that are currently employed for shipboard analysis of trace metals in seawater voltammetric, chemiluminescence and colorimetric methods. Instrumentation and methods are described for collecting surface seawater using pumping, with subsequent on-line analysis by stripping voltammetry. The review is illustrated with data for oceanic and coastal distributions of ...

  • Geo-engineering, the Law of the Sea, and Climate Change

    Plans to address climate change increasingly include proposals for geo-engineering projects, whose effects are likely to be global, at best only partly predictable, not necessarily wholly benign, and extend beyond their objective. Geo-engineering proposals should receive detailed, precautionary scrutiny by the international community, which requires sophisticated international legal instruments ...

  • A Review of Migratory Bird Flyways and Priorities for Management

    This document, commissioned by the Convention on Migratory Species (CMS), and developed with the CMS Flyways Working Group, outlines the scientific and technical issues for conservation of migratory birds and their habitats, and relevant international instruments, initiatives and processes. It is in three parts namely: Part 1 (previously Review 1) – a review of CMS and non- CMS existing ...

  • Scintillation effect in LISST – The importance of temperature differences

    Scintillation is what makes stars twinkle. It is what causes mirage in deserts or on hot surfaces. It is what causes shimmer underwater in the vicinity of hot vents in oceans. These effects result from temperature fluctuations in air or water. The same effect can occur in a LISST optics cell if not properly controlled . The importance of scintillation in LISST instruments first became evident ...

  • Global aerosols studied by NILU

    Aerosols scatter and absorb solar radiation and thereby influence the radiation in the atmosphere and the global climate. To understand the climate system and the ongoing climate change it is important to know the distribution of aerosols in the atmosphere. Satellites provide an extremely useful tool to study this distribution, especially since it is very inhomogeneous with respect to ...

  • 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 ...

  • 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. ...

  • CU-Boulder leading study of wind turbine wakes

    While wind turbines primarily are a source of renewable energy, they also produce wakes of invisible ripples that can affect the atmosphere and influence wind turbines downstream -- an issue being researched in a newly launched study led by the University of Colorado Boulder's Julie Lundquist, assistant professor in the atmospheric and oceanic sciences department. The study, called the Turbine ...
