©2026 Biological and Chemical Oceanography Data Management Office.This dataset presents particle number spectra from the DESAFÍO expedition (PID2020-118118RB-100), collected in the northeastern subtropical Atlantic between the Azores and Canary Islands (31 Jan–2 Mar 2023). Particle images were acquired with a Focused Shadow Imaging System (11.75 μm/pixel) mounted on a CTD/rosette across 22 casts, spanning three regions and three depth strata (epipelagic, mesopelagic, bathypelagic). Particles ≥23.5 μm were classified by optical density into low-OD (gel proxy) a...
