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....
The USGS has evaluated Sequoia’s LISST-ABS at 10 streamflow-gaging stations, collecting LISST-ABS and suspended sediment concentration (SSC) data between January 2016 and February 2018. The evaluation also compared the LISST-ABS to standard turbidity sensors normally used by the USGS. The results...
NOAA, The National Oceanic and Atmospheric Administration was founded in 1970 and thus celebrates its 50th anniversary in 2020. Learn more about NOAA and its story in this almost 200-page anniversary book. As a proud sponsor of the book, you can read it on Sequoia’s website below. See our ad on p....
The LISST-200X can be used in profiling applications, check out the specifics in this video! https://www.sequoiasci.com/wp-content/uploads/2020/09/LISST-200X_V5.mp4
Earlier this month, Sequoia sent out a survey to our LISST-ABS users to get feedback on how we can continue to improve this instrument. Survey participants were entered into a drawing for $200. Our winner was Cindy Crane from the Prince Edward Island (PEI) Department of Environment, Water and Climate...
In 2008, Sequoia Scientific’s Dr. Ole Mikkelsen co-authored and published a paper: The Influence of Schlieren on In-situ Optical Measurements Used for Particle Characterization. This paper was based on data collected during his postdoctoral work in Canada and the UK between 2002 and 2007. It was...
24th July 2020 In the last several years, Sequoia has introduced a range of new or upgraded instruments: LISST-200X, LISST-SL2, LISST-Holo2, LISST-ABS, LISST-AOBS, LISST-HAB, LISST-Black, LISST-Glider, Hyper-bb and LISST Horizon. Such an expansion increases inventory cost, documentation requirements,...
