Understanding the composition of suspended particles in the ocean is essential for unraveling biogeochemical cycles, assessing ecosystem health, and improving remote sensing algorithms. Among the suite of optical tools available to oceanographers, in...
In aquatic optics and phytoplankton ecology, chlorophyll-a has long been the go-to proxy for estimating biomass and productivity. However, as our understanding of aquatic ecosystems deepens, so does our need for more nuanced tools. One such tool is Sequoia’s...
Sequoia’s LISST-200X enjoys popularity amongst microplastics researchers. The instrument has been used to analyze microplastic particle distributions from disposable masks[i] , investigate interactions between oil droplets and microplastics[ii],[iii],[iv]...
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...
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)...
