  • Measurement of TOC in High-Salt Sample

    The quantity of organic matter in seawater is important in the research and monitoring of marine pollution as an indicator of organic pollution. The salt content in seawater is typically about 3.5 %, but using the Shimadzu total organic carbon analyzer, it is possible to measure the TOC directly without dilution or other pretreatment procedures. Here, we introduce an example of measurement of ...

  • New Maps from Old Photos: Measuring Coastal Erosion

    U.S. Geological Survey scientists and their coauthors from the California Coastal Records Project have found a way to use historical aerial photographs not just to see evidence of coastal erosion, but to accurately measure how much has occurred over time. Applying a low-cost technique called “structure-from-motion” to five sets of oblique aerial photos spanning the years ...

  • Sample Handling Strategies for Accurate Lead-In-Soil Measurements in the Field and Laboratory

    ABSTRACT The inhomogenous lead-in-soil matrix can present serious obstacles to accurate sample collection and handling. In typical lead-in-soil measurement, particle size related errors in sampling and sample handling often exceed all other sources of error. The magnitude of error can vary widely depending on the particulate nature of the lead contaminant and the effectiveness of control ...

  • Stochastic models of oil spill processes

    This paper models the occurrence of an environmental accident as a stochastic event. In particular, the situation of an oil spill is explored. Characteristics of the ship operator, and the different types of the ship's operating environment determine a stochastic process governing the time patterns and size of spills. It is shown that both the time distribution of different types of oil spill and ...

  • 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 ...

  • Monitoring Hydrocarbons in Bilge Water

    The Situation Various processes onboard ships, such as machinery wash-down, maintenance, and leakage generate oily wastewater. This contaminated water flow collects in the bilge of the ship. Marine diesel, lubricating oils, grease, as well as garbage may be present in bilge water. The bilge water is discharged overboard, with oil and grease concentrations in the discharged water limited ...

  • 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 ...

  • Questions and Answers on the Directive on Maritime Spatial Planning

    Why do we need a Directive on Maritime Spatial Planning? The uncoordinated use of coastal and maritime areas creates competition for maritime space and is an inefficient use of marine resources. A lack of predictability regarding appropriate access to the maritime space has created an uncertain climate for investment. With rapidly increasing demand for maritime space for new ...

  • Impact of sound attenuation by suspended sediment on ADCP backscatter calibrations

    Abstract. Although designed for velocity measurements, acoustic Doppler current profilers (ADCPs) are widely being used to monitor suspended particulate matter in rivers and in marine environments. To quantify mass concentrations of suspended matter, ADCP backscatter is generally calibrated with in situ measurements. ADCP backscatter calibrations are often highly site-specific and season ...

  • Sensitive environments - Enhesa’s regulatory registers assure protection

    Oil and gas exploration and production are perhaps the most closely scrutinized activities of all when it comes to protecting the environment, and even more so when it comes to sensitive, or even protected environments. Indeed, a company’s very permission to operate will be contingent at the very least on meeting both the spirit and the letter of the law governing the protection of such ...

  • Case study - Public-private partnership successfully tests leakwise early oil spill detection sensor in the tidal Delaware river

    Background In the summer of 2011, the Delaware River Basin Commission (DRBC) and the U.S. Geological Survey (USGS) collaborated with GE Analytical Instruments on a unique test deployment of an oil sheen sensor in the tidal Delaware River. The idea for the test deployment arose during meetings of the Delaware River and Bay Oil Spill Advisory Committee, which includes organizations and ...

  • 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 ...

  • Flood risks and environmental vulnerability — Exploring the synergies between floodplain restoration, water policies and thematic policies

    Nowadays floodplain areas are reduced in size or no longer function as active floodplains, thereby impacting on the delivery of environmental services to local and regional communities and economies. These services include regulating services such as protection against floods or water purification; provisioning services, such as nutrient collection and fertile soil formation; and cultural ...
