This dataset includes raw and processed data from Laser In Situ Scatterometer and Transmissometer Particle Size Distributions (LISST PSDs) used in Cael & White (2020). LISST-based PSDs from suspended materials were collected in bottle samples at multiple depths at Station ALOHA in June 2019 onboard R/V Kilo Moana cruise KM1910.
Particle size distribution (PSD) measurements were made in June 2019 at Station ALOHA (22.75°N, 158°W) in the North Pacific Subtropical Gyre aboard the R/V Kilo Moana (KM1910). PDSs were measured using the Laser In Situ Scatterometer and Transmissometer 100X (Type B, Sequoia Scientific Inc., hereafter LISST) which uses laser diffraction in an approximately 100 ml sample volume to estimate the PSD via inversion into 32 logarithmically spaced particle size classes.
Suspended material PSDs were measured from discrete bottle samples collected using a rosette at 5, 75, and 150 meter depths. PSDs were then measured from the LISST in discrete chamber mode, with twenty diffraction measurements made from each sample. This process was repeated in triplicate. Blank samples were also collected in triplicate to provide the background particle concentrations, using the collected sample blanks. Data were analyzed using the standard spherical particle inversion provided by the LISST manufacturer.
Addtional details on sampling strategy and procedures can be found in Cael & White (2020).
