©2026 Biological and Chemical Oceanography Data Management Office.This dataset provides depth-resolved particle and hydrographic profiles 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 abundance and total particle volume, derived from a Focused Shadow Imaging System (FoSI) mounted on a CTD/rosette, were resolved to 1-m depth bins and paired with co-located CTD profiles of temperature, salinity, dissolved oxygen, fluorescence, and turbidit...
