…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...
Since 1995, Sequoia Scientific, Inc. has been the global leader in technologies for submersible and field measurements of particles and particle size distributions. This article shows a few examples where our instruments have been used for various dredging and sediment monitoring applications. USACE...
Sequoia Scientific, Inc., together with MIT and UCSD, were awarded a two-year SBIR grant from ARPA-E in May 2020. The grant was for developing an instrument – the LISST-RTSSV – for monitoring the environmental effects of deep-seabed mining. In late 2020 an opportunity arose to collaborate with...
Scientist Julien Laliberté with Fisheries and Oceans Canada has recently collected data using the Hyper-bb, a hyper-spectral backscatter instrument designed by Sequoia Scientific, Inc. Dr. Laliberté states, “My objective is to use ocean color remote sensing to characterize the St. Lawrence Estuary...
Prototipo de instrumento sumergible que consiste en un medidor de micropartículas y secciones de velocidad de sedimentación a la medida de macropartículas Sequoia Scientific Inc. se enorgullece en anunciar que ha recibido un apoyo económico SBIR (Programa de Investigación de Innovación para Pequeñas...
A Sequoia Scientific, Inc. tem o orgulho de anunciar a receção de um subsídio SBIR do Departamento de Energia dos EUA (DoE) Agência de Pesquisa Avançada de Projetos – Energia (ARPA-E) para desenvolver uma nova tecnologia de instrumento ambiental que monitorizará os elementos-chave das plumas...
LISST-Tau profiles from 4.5 day glider deployment. The LISST-Tau has been tested on several autonomous profiling glider deployments. The figure shows beam-c data collected by the LISST-Tau over a four and half day glider deployment. 24,000 measurements from more than 20 profiles down to 960 m are shown....
