Research and innovation continue to thrive within the science and engineering teams at Sequoia Scientific, Inc. (Sequoia), which announces today the Hyper-bb product offering. Sequoia scientist Dr. Wayne Slade has developed a hyperspectral backscattering instrument (Hyper-bb) through a NASA Phase II SBIR (Small Business Innovation Research) grant. A prototype has been delivered to NASA for testing. This is Dr. Slade’s and Sequoia’s second SBIR-funded development and delivery in 2019.
Hyperspectral backscattering has been identified as a measurement gap in closure and validation studies for planned hyperspectral ocean colour sensors, such as NASA’s planned Plankton, Aerosols, Cloud, ocean Ecosystem (PACE) mission. Hyper-bb employs technology similar to existing backscattering sensors used in the ocean optics community, but extends the spectral coverage using continuously varying bandpass technology. Hyper-bb’s backscattering measurements with higher spectral coverage complement other currently available instruments measuring hyperspectral optical properties, including absorption, beam attenuation, and radiometry.
The Hyper-bb is a submersible instrument, rated to 600 meters, with internal data storage, and is easily integrated into existing moored and profiling packages. The backscattering measurements collected by the Hyper-bb are highly relevant to ocean colour remote sensing and ocean biogeochemistry research.
The Hyper-bb product is expected to be available for order in Q1 2020. For more information, get in touch!
In a world’s first, Sequoia Scientific, Inc. has invented a method (patent pending) to pair turbidity data with their acoustic backscatter sensor; the LISST-ABS. This pairing of acoustic and optical data leads to a radically-improved estimate of Suspended Sediment Concentration (SSC), compared to that which either sensor can provide on its own. In fact, measurements of SSC with this new method are within a factor of 2 of the actual value (e.g. based on sampling and subsequent filtration).
This is an order of magnitude improvement over currently used technologies.
To get this incredible innovation into the hands of the world, Sequoia is introducing a new instrument system, the LISST-AOBS Super-Turbidity Meter.
What’s more, all existing LISST-ABS sensors can be expanded to the LISST-AOBS Super-Turbidity Meter. Also, all existing turbidity sensors can be expanded to the LISST-AOBS Super-Turbidity Meter.
The implications of the new method and the introduction of the LISST-AOBS Super-Turbidity Meter are two-fold:
1) Existing regulations (e.g. for stormwater, construction, environmental monitoring) that call for the monitoring of turbidity can be adhered to while…
2) the user – at the same time – can obtain an accurate estimate of SSC.
The impact of this new technology is sure to be huge. According to the United States Environmental Protection Agency, excessive sediment is the leading cause of impairment of the Nation’s waters – read the report here. High SSC values influence virtually all aspects of aquatic life in a detrimental manner. So accurate measurements of SSC with low-cost sensors that can be deployed for months or years are will bolster a wide range of environmental quality programs, remediation efforts, court cases and more.
The LISST-AOBS Super-Turbidity Meter can help provide the data needed to make the decisions that will protect the World’s waters.

Sequoia Scientific‘s fantastic new, NASA-funded prototype – LISST-Horizon, (previously known as FERPS; Flow-through Extended Range Particle Sizer) – has now been delivered for testing. We can’t wait to see the results.
This exciting, new instrument is designed (through NASA’s SBIR Program) for the continuous and automated measurement of suspended Particle Size Distribution in flow-through systems. Particle Size Distribution (PSD) is a key environmental parameter – essential for carbon cycle science, ecosystem and fisheries modelling, and harmful algal bloom detection and predication. Though its variability in the ocean isn’t well understood due to the present challenges of routine measurement. It’s not easy to track PSD over long stretches of time, or across large areas, as current methods are time-consuming, expensive and non-automated. Yet large PSD data sets are extremely important for research such as NASA’s new PACE project.
Sequoia set out to bridge this data gap with a brand new instrument capable of the constant measurement of PSD over large areas. The LISST-Horizon is self-contained instrument for bench-top deployment in a research vessel laboratory, designed to be plumbed into the continuous stream of uncontaminated seawater that travels through the ship’s flow-through system. As vessels traverse the oceans, Sequoia’s new prototype will use laser scattering to estimate the PSD of the water below them across a wide range of sizes. From sub-micron to hundreds of microns, even covering picoplankton to mesoplankton size scales. This allows for the continuous measuring of particle concentration, as well as inherent optical properties, beam attenuation and volume scattering.
Once completed, the LISST-Horizon will be an incredible new addition to the field of ocean optics, ocean biology, and biogeochemistry.
Honey bees are essential for the pollination of about one third of the food we eat – including fruit, vegetables, oils, seeds and nuts – yet their health and ability to pollinate our crops is under serious threat.
To help tackle this worldwide problem, CSIRO is leading the Global Initiative for Honey bee Health – an international collaboration of researchers, beekeepers, farmers, industry, and technology companies aimed at better understanding what is harming bees and finding solutions to help secure crop pollination. Integral to the research effort are micro-sensors that are manually fitted to bees which work like a vehicle e-tag system, with strategically placed receivers identifying individual bees and recording their movements in and around bee hives.
“The tiny technology allows researchers to analyse the effects of stress factors including disease, pesticides, air pollution, water contamination, diet and extreme weather on the movements of bees and their ability to pollinate,” Professor Paulo de Souza, CSIRO Science Leader, said. “We’re also investigating what key factors, or combination of factors, lead to bee deaths on mass.”
“The sensors, working in partnership with Intel software, operate in a similar way to an aeroplane’s black box flight recorder in that they provide us with vital information about what stress factors impact bee health.”
As bees are normally predictable creatures, changes in their behaviour indicate stress factors or a change in their environment. By modelling bee movement researchers can help identify the causes of stress in order to protect the important pollinating work honey bees do and identify any disease or other biosecurity risks. CSIRO Pollination Researcher, Dr Saul Cunningham, said Australia has been very lucky, so far, to be the only country that doesn’t have the devastating Varroa mite, which has wiped out bee colonies overseas at an alarming rate.
“This puts Australia in a good position to act as a control group for research on this major issue that could one day become our problem too,” Dr Cunningham said. However, Australia’s horticulture and agricultural industries are particularly vulnerable to declines in honey bee populations as they rely on un-managed feral honey bees for much of their crop pollination.
“Our managed bee pollination services would be hard-pressed to meet the extra demand required to replace the key role un-managed honey bees play so, the outcome would likely be a drop in crop production and a rise in prices of popular food staples like fruit and veggies,” Dr Cunningham said.
The international initiative is being mounted to assist in uniting the efforts of those working in the critical area of protecting bee health. “The time is now for a tightly-focused, well-coordinated national and international effort, using the same shared technology and research protocols, to help solve the problems facing honey bees worldwide before
it is too late,” Professor de Souza said.
The GIHH proudly partners with the following industry members – Intel, Hitachi Chemical, Nissin Corporation and Vale, and brings together scientists from Australia, New Zealand, Brazil, Mexico and the United Kingdom.
