Analysis of multiple scattering errors in LISST-VSF volume scattering function measurements using Monte Carlo simulations and experimental data
Ugulen, Håvard Stavn; Sandven, Håkon; Hamre, Børge; Kristoffersen, Arne Skodvin; Sætre, Camilla (Journal article; Peer reviewed, 2021)A Monte Carlo algorithm has been developed to investigate the effects of multiple scattering on the volume scattering function measured by the LISST-VSF instrument. The developed algorithm is compared to experimental results ... -
Efficient Monte Carlo simulation reveals significant multiple scattering errors in underwater angular scattering measurements
Ugulen, Håvard Stavn; Sandven, Håkon; Hamre, Børge; Kristoffersen, Arne Skodvin; Sætre, Camilla (Journal article; Peer reviewed, 2022)Multiple scattering can severely affect the accuracy of optical instrumentation. Variance reduction methods have been implemented to improve a Monte Carlo model developed to simulate volume scattering functions measured ... -
In situ measurements of the volume scattering function with LISST-VSF and LISST-200X in extreme environments: evaluation of instrument calibration and validity
Sandven, Håkon; Kristoffersen, Arne Skodvin; Hamre, Børge; Chen, Yi-Chun (Journal article; Peer reviewed, 2020)The LISST-VSF and LISST-200X are commercial instruments made available in recent years, enabling underwater measurements of the volume scattering function, which has not been routinely measured in situ due to lack of ... -
Seasonality and drivers of water column optical properties on the northwestern Barents Sea shelf
Sandven, Håkon; Hamre, Børge; Petit, Tristan; Röttgers, Rudiger; Liu, Hongbo; Granskog, Mats (Journal article; Peer reviewed, 2023)Hydrographic and bio-optical measurements were conducted along a south–north transect on the northwestern Barents Sea shelf from early spring to late summer in 2021. Strong climate change manifestations observed in this ...
