The articles discuss the use of Sequoia’s LISST-VSF instrument, a submersible multi-angle polarized light scattering meter measuring the volume scattering function (VSF) in situ. Commercially available since 2012, the LISST-VSF’s capabilities have...
Sequoia’s Laser In Situ Scattering and Transmissometry (LISST) particle size analyzers have significantly advanced the understanding of flocculation in aquatic environments. Since the mid-1990s, LISSTs have often replaced or supplemented older technologies...
In 2019 Sequoia published a short note on our website regarding the feasibility of measuring plastic particles in situ. Two main conclusions were drawn: If one considers the number concentration of plastic particles (α), and the sampling volume (SV)...
The University of Hawai’i at Manoa (UH) operates the Hyper-bb hyperspectral backscatter instrument. Professor Angelicque White uses the instrument as a component of the open ocean Hawai’i Ocean Time-series (HOT) program to collect key datasets...
Kelly Thomas, Biological Oceanographer A longtime user of LISST instruments, the University of Alaska Fairbanks has been using the new, LISST-200X-style 4,000m rated LISST-Deep from Sequoia Scientific, Inc. The LISST-Deep instrument measures in-situ particle...
