Natural oil slicks in the western Gulf of Mexico are used to determine the sun glint threshold required for optical remote sensing of oil films. The threshold is determined using the same-day image pairs collected by Moderate Resolution Imaging Spectroradiometer…
It has long been observed that oil slicks under sunglint can reverse their optical contrast against nearby oil-free seawater. Such a phenomenon has been described through both empirical statistical analysis of the sunglint strength and modeled theoretically using a critical…
Surface oil footprint and trajectory of the Ixtoc-I oil spill determined from Landsat/MSS and CZCS observations. Shaojie Sun, Chuanmin Hu, John W. Tunnell Jr., Marine Pollution Bulletin. December 2015. doi:10.1016/j.marpolbul.2015.10.036 Abstract: The Ixtoc-I oil spill occurred in 1979 in shallow waters (50 m)…
On 23 July 2013, a marine gas rig (Hercules 265) ignited in the northern Gulf of Mexico. The rig burned out of control for 2 days before being extinguished. We conducted a rapid-response sampling campaign near Hercules 265 after the…
Using fine spatial resolution (~ 7.6 m) hyperspectral AVIRIS data collected over the Deepwater Horizon oil spill in the Gulf of Mexico, we statistically estimated slick lengths, widths and length/width ratios to characterize oil slick morphology for different thickness classes.…
On July 23, 2013 a marine gas rig (Hercules 265) ignited in the northern Gulf of Mexico. The rig burned out of control for two days before being extinguished. The C-IMAGE and CARTHE Consortia conducted a rapid-response sampling campaign near Hercules 265…
The role of Mississippi River discharge in offshore phytoplankton blooming in the northeastern Gulf of Mexico during August 2010. Brendan O'Connor, Frank E, Muller-Karger, Redwood W. Nero, Chuanmin Hu, Ernst B. Peebles. Remote Sensing of the Environment. February 2016. DOI: 10.1016/j.rse.2015.11.004 Abstract: A…
A newly utilized mass spectrometry method, FTICR-MS, gives researchers the ability to screen lipid biomarkers found in sediments at a faster rate than before. A new publication from the University of Calgary-Department of Geosciences and C-IMAGE members details the possible…
Remote detection of pelagic Sargassum is often hindered by its spectral similarity to other floating materials and by the inadequate spatial resolution. Using measurements from multi-spectral satellite sensors (Moderate Resolution Imaging Spectroradiometer or MODIS), Landsat, WorldView-2 (or WV-2) as well…
The Deepwater Horizon blowout in April, 2010, represented the largest accidental marine oil spill and the largest release of chemical dispersants into the environment. While dispersant application may provide numerous benefits to oil spill response efforts, the impacts of dispersants…
