LISST digital holography at depth!

Dr Sari Giering and her ‘ANTICS’ team (a project funded by the European Research Council) at the National Oceanography Centre in Southampton, UK, has employed Sequoia’s LISST-Holo2 instrument to collect key ocean data sets from the Twilight Zone (the region between the sunlit surface and 1000 m depth) [LINK: The Twilight Zone – Porcupine Abyssal Plain Observatory (]. The research area which the team is focused on combines shipboard measurements, laboratory analyses, data synthesis and numerical modelling in order to better understand and quantify ocean carbon storage. Recently her team shared at-sea cruise images and actual collected holograms.

The 600m rated LISST-Holo2 performs in a diverse range of applications including sediment & flocculation studies, algae & plankton studies, frazil ice formation, aeolian sediment transport and more. Holography permits a photograph-like view of particles in water, allowing undisturbed views of the most fragile flocculated particles (flocs), or plankton and other material.
