the oil slick

Understanding oil slick thickness is important for spill response and assessment — responders need to know where the heavy oil is to guide deployment of limited response assets, or the .There is a need to measure oil slick thickness [1]. There are presently few reliable methods, either in the laboratory or in the field, for accurately measuring oil-on-water slick thickness [1].

There has long been a need to measure oil slick thickness, both within the oil spill response community and among academics in the field. There are presently no reliable methods, either in the laboratory or in the field to provide an accurate measure ofoil-on-water slick thickness. The ability to measure oil slick thickness wouldThe OR&R multi-year Canadian Multi Partner Research Initiative funded project involved several years of collaboration including conducting a workshop with multiple oil spill response and assessment stakeholders, followed by testing with eight different scientists who can estimate and/or measure oil slick thickness.The measurement ofoil slick thickness has long been a relative science, with absolute measurement eluding the remote sensing community. Knowledge ofoil slick thickness would significantly benefit both the spill response and scientific research communities. The effective direction ofoil spill countermeasures such as in situ burning and dispersant application .The measuring schematic of the oil slick thickness using an ultrasonic transducer in the pulse-echo mode is shown in Fig.1(a), the thickness of the oil slick can be calculated by the following equation, d = V(T) t 1 2 (1) where d denotes the thickness of oil slick, V(T) is the speed Fig.1 The measurement schematic of the oil slick thickness .

way to measure oil-on-water slick thickness. Until recently there was no reliable laboratory or field method to provide an accurate measurement of oil slick thickness. Knowledge of slick thickness will result in more effective direction of oil spill countermeasures including dispersant application and in situ burning. In reality, the . t:,.. -~~~~ The in situ measurement of thick oil slick thickness (>0.5 mm) and area in real time in order to estimate the volume of an oil spill is very important for determining the oil spill response strategy . Expand. 1. PDF. Save. Ultrasonic Measurement on the Thickness of Oil Slick Using the Remotely Operated Vehicle (ROV) as a Platform. The thickness of oil spills on the sea is an important but poorly studied topic. Means to measure slick thickness are reviewed. More than 30 concepts are summarized.

During an oil spill response, one of the main challenges is the ability to measure, in situ and in real time, the oil slick thickness at different locations throughout the slick.

How to Measure Slick Thickness (or not) Merv F. Fingas Spill Science Edmonton, Alberta, Canada [email protected] Abstract Thickness of oil spills is an important but a poorly understood topic. There is a continuing need to measure the thickness of oil spills, and the difficulties is that ground truthing and verification methods are generally not available for most thickness measurement methods. The thickness of oil spills on the sea is an important but poorly studied topic. Means to measure slick thickness are reviewed. More than 30 concepts . Spectral Domain Optical Coherence Tomography (SD-OCT) with 1300 nm wavelength is employed to detect three-dimensional (3-D) volumetric structure, surficial characteristic and thickness of oil slicks on water surface.The results show that petroleum slick possesses bigger diffusion area but much thinner than diesel slick at the same volume on . Slick thickness measurement is problematic because there are very few operational methods. Second, the visual color methods currently tried may be incorrect. There are a few simple techniques to estimate slick thickness in the range 0.1–5 μm (0.0001–0.0005 mm), but these do not relate to most oil spill needs.

Rapid detection of marine oil spills is becoming increasingly critical in the face of frequent marine oil spills. Oil slick thickness measurement is critical in the hazard assessment of such oil . The laser-ultrasonic remote sensing of oil thickness (LURSOT) sensor measures the time taken for ultrasonic waves to travel through oil and provides a direct measurement of oil-slick thickness (Brown et al., 1996, Brown et al., 2005, Brown et al., 2006); however, because of the many uncertainties involved, it remains difficult to determine oil .
