Remember the pandemic? Sequoia had purchased 80 Sequoia trees at a nursery in Germany and they were en route to Oceanology International in the UK where we were planning to exhibit. Oceanology 2020 was cancelled, leaving our German distributor, MacArtney...
In the 1960’s oceanographers started suggesting that sinking particles were a main source of food and nutrient delivery to deep-sea organisms. Sediment traps were soon conceived and deployed to investigate further (Wiebe et al., 1976). It was rapidly...
When we think of pollution in our rivers, lakes, or oceans, we often picture oil slicks or floating plastic bottles. But suspended sediment is an important agent that must not be overlooked. Suspended sediment can act like a vehicle for pollutants, carrying...
Understanding particle behavior in the aquatic environment is fundamental to unraveling key processes in biogeochemistry, sediment transport, and ecosystem dynamics. Since 1995, Sequoia’s LISST and Hyper instruments have become important tools for quantifying...
Sequoia’s LISST-200X is popular amongst microplastics researchers. The instrument has been used to analyze microplastic particle distributions from disposable masks, investigate interactions between oil droplets and microplastics and measure microparticles...
