Taxa-resolved particle size distributions derived from an IFCB (3-100 micrometers) at Station ALOHA (2017-2025; HOT294 - HOT361)

We provide surface (~7m depth) particle size distribution data collected with an Imaging FlowCytobot (IFCB; McLane, East Falmouth, MA, USA) as part of the Hawaii Ocean Time Series program (HOT; https://hahana.soest.hawaii.edu/hot/) covering the 2017-2025 period (HOT294 - HOT 361). In brief, we provide cruise-averaged particle size distributions (both particle volume [microliters per liter per micron] and counts [number of particles per liter per micron]) over 50 log-spaced diameter bins ranging between 3-100 micrometers. We also provide particle diameters (estimated from cross-sectional areas), as well as major and minor axis lengths for all individual particles imaged by the IFCB during the above mentioned cruises, along with relevant metadata (time, latitude, longitude of collection of each particle).
