…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...
…Wherein we learn about product development and get to meet some new employees (Part III can be found here) A summer visit from Japan lead to Sequoia’s first distributorship outside the US. Soon, more distributors were signed up in Korea, Taiwan, and other countries. During a visit to the Yangtze...
The History of Sequoia – Part III …Wherein we learn about start-up accounting and get an interesting take on the value of a website (Part II can be found here) Diana Suzuki It is intimidating to create the infrastructure to get funds under federal Contracts and Grants. Our heroes needed a trusted...
…Wherein we learn about the consequences of a walk on Powell Street in San Francisco. (Part I can be found here) In 1993 our heroes realized that the CCD array with an ND film was inconvenient. With a significant investment in silicon sensor technology, the first multi-ring silicon detector was developed...
…Wherein we learn about our heroes first idea and the origin of the LISST acronym Time: Sometime in the 1980’s Where: Somewhere in the North Atlantic (probably) On board the R/V Oceanus, a scientific party deployed another round of deep-sea instruments, measuring parameters for sediment transport....
O-rings are so ubiquitous today – at least for all of us building underwater instrumentation for the underwater technology industry – that we generally think of them as something that has always been around. But that is not the case. The other night Sequoia’s President, Ole Mikkelsen, was lying...
New release of LISST-ABS software v2.1 – improved LISST-AOBS capability! To accommodate the growing number of LISST-AOBS customers, the LISST-ABS software now also handles LISST-AOBS data. The LISST-ABS software v2.1 will now connect to a LISST-ABS or AOBS, auto-detect the instrument mode and configure...
