Sequoia Scientific’s LISST-100X Monitors Oil Droplets and Concentration in the Gulf of Mexico

The LISST-100X submersible laser sensor from Sequoia Scientific has been used intensively by the oil spill research community in the last few years in order to measure the size and concentration of oil droplets and estimate dispersant effectiveness.

At present, all available LISST-100X rental units are deployed in the Gulf of Mexico as part of the spill monitoring efforts after the Deepwater Horizon accident, where scientists and consultants from SL Ross in Ottawa, Ontario and Cooger (DFO) in Nova Scotia are using the LISST-100X for their monitoring efforts in the Gulf. Some scientific papers that have been published in peer-reviewed literature, demonstrating the use of LISST-100X for this purpose, include:
