In Situ Sensor for the Detection of Oil Spill in Seawater Using Microwave Techniques

Aliyu Dala, Tughrul Arslan
2022 Micromachines  
The changes in the dielectric properties of the media resulted in changes in both the S11 and S21 signifying and detecting an occurrence of the oil spillage.  ...  Thus, by employing radio frequencies, oil spillage was detected using the in situ monitoring device in seawater.  ...  Conflicts of Interest: The authors declare no conflict of interest.  ...

Volumetric Mapping of Methane Concentrations at the Bush Hill Hydrocarbon Seep, Gulf of Mexico

William P. Meurer, John Blum, Greg Shipman
2021 Frontiers in Earth Science  
The studies were carried out using buoyancy driven gliders equipped with methane sensors for near real time in situ detection.  ...  One glider was equipped with an Acoustic Doppler Current Profiler (ADCP) for simultaneous measurement of currents and methane concentrations.  ...  Oil droplets are not reliably imaged using MBES and so direct detection of seafloor oil seepage locations is commonly done via detection in sediments using drop cores or direct observation.  ...

Underwater Pipeline Oil Spill Detection Based on Structure of Root and Branch Cells

Huajun Song, Jie Song, Peng Ren
2020 Journal of Marine Science and Engineering  
To solve this problem, combining with underwater image processing technology, an unsupervised detection algorithm for oil spill in underwater pipelines is proposed for the first time.  ...  Then,the HSV (Hue, Saturation, Value) color space of the image is used to screen the oil spill region meeting the threshold requirements.  ...  Dhont proposed the combined use of SAR and underwater gliders for oil seeps detection [2] . However, due to poor timeliness, leakage points cannot be found in time and the cost is high.  ...

Fate of Methane Released From a Destroyed Oil Platform in the Gulf of Mexico

Mauricio Silva, Camilo Roa, Nizar Bel Haj Ali, Carrie O'Reilly, Tarek Abichou, Ian R. MacDonald
2022 Frontiers in Earth Science  
The CRDS detected transient peaks of methane as high as 15.9 ppmv ppm while oil was being recovered to a ship from underwater storage tanks.  ...  In 2004, destruction of a Gulf of Mexico oil platform by Hurricane Ivan initiated a discharge of oil and gas from a water depth of 135 m, where its bundle of well conductors was broken below the seafloor  ...  Satellite SAR images have identified over 900 persistent oil seeps in the Gulf (MacDonald et al., 2015) and elsewhere (Jatiault et al., 2017) , and many of these have been confirmed by submersible sampling  ...
