January’s featured paper is here! Lepage H, Masson M, Delanghe D, Le Bescond C (2019): Grain Size Analyzers: Results of an Intercomparison Study. SN Applied Sciences (2019) 1:1100 | Tl;dr: No instrument in particular stood out as better...
As reports over the last 3-4 decades demonstrate increasing plastic concentration in the oceans, public and regulatory concerns have grown in parallel. Sequoia Scientific Inc. and other instrument manufactures are thus frequently contacted by scientists...
The short explanation Briefly, the difference between turbidity and Super-Turbidity (Patent Pending) can be summarized as follows: Turbidity (NTU) = Optical Backscatter; Needs Calibration for SSC; less accurate Super-Turbidity (mg/l) = Optical & Acoustic...
LISST-AOBS has Nearly Uniform Sensitivity Across Wide Grain Sizes! B Why the Acousto-Optic Super-Turbidity Sensor LISST-AOBS? The sensitivity (Volts/[mg/L] ) of Optical turbidity sensors varies inversely with grain size. Turbidity sensors are highly...
Welcome to the first installment of Sequoia’s Fun Fact Series! Irregularly, we’ll post interesting facts about sediments in this Fun Fact Series. To kick it off, we’ll go all the way back to the beginning – the very first known...
