…Wherein we’ll learn about the LISST-AOBS, Hyper-bb and LISST-Horizon. (Part XII can be found here: https://www.sequoiasci.com/article/the-history-of-sequoia-part-xii/ ) After the LISST-ABS introduction in 2016, Yogi noted that the LISST-ABS and turbidity sensors have opposite-trending changing sensitivities...
…Wherein we’ll learn about the LISST-ABS and the LISST-200X (Part XI can be found here: https://www.sequoiasci.com/article/the-history-of-sequoia-part-xi/) In 2013 Yogi came up with an idea for a point sensor for measuring suspended sediment concentration; the LISST-ABS. It was developed in collaboration...
…Wherein we’ll learn about the LISST-VSF and some arriving and departing employees. (Part X can be found here: https://www.sequoiasci.com/article/the-history-of-sequoia-part-x/ ) The LISST-VSF In 2011, Sequoia finished an SBIR (Small Business Innovation Research grant) and developed a full-angle...
…Wherein we’ll learn about the use of LISSTs during the Deepwater Horizon accident in 2010 (Part IX can be found here: https://www.sequoiasci.com/article/the-history-of-sequoia-part-ix/) Particle size distribution is important in many areas. When the Deepwater Horizon disaster occurred in the Gulf...
…Wherein we’ll learn about the LISST-Holo and what else happened in the late 2000’s! (Part VIII can be found here: https://www.sequoiasci.com/article/the-history-of-sequoia-part-viii/) At the PiE 2008 meeting, one of the presentations was by a young scientist from the UK – George Graham. He showed...
…Wherein we’ll learn about the LISST-Portable, and the first Particles in Europe (PiE) conference. (Part VII can be found here: https://www.sequoiasci.com/article/the-history-of-sequoia-part-vii/) Way back in the early 2000’s Chuck had an idea for a laboratory particle sizer based on the LISST-100X...
…Wherein we’ll learn about the LISST-Infinite, LISST-StreamSide, and the LISST-SL. (Part VI can be found here: https://www.sequoiasci.com/article/the-history-of-sequoia-part-vi/ ) Remember from Part VI that Dr. Gray from USGS had proposed the LISST-25? Around the same time, he and FISP also proposed...
Sequoia’s LISST-Holo2 captures holograms of suspended particles. Upon processing, particle size, distribution, concentration and images of all particles in the beam are recovered. The LISST-Holo2 has traditionally been used for suspended particles in the aquatic environment. However, Cohn et al. (2022)...
…Wherein we’ll learn about the LISST-25 and the LISST-Wing (Part V can be found here: https://www.sequoiasci.com/article/the-history-of-sequoia-part-v/ ) In the late 1990’s, Yogi participated in several FISP (Federal Interagency Sedimentation Project) technical committee meetings upon invitation...
…Wherein we get an insight into some of the first LISST user workshops in the late 1990’s (Part IV can be found here) The number of LISST users continued to grow and with it questions about best practice, data analysis, interpretation and so on. To address these questions, our heroes held the first...
