[FoSI-spectra-DESAFIO] - Particle number spectra of low and high-optical-density particles (LODP and HODP) from Focused Shadowgraph Imaging (FoSI) in the NE Atlantic, Jan-Mar 2023 (DESAFÍO) (Linking optical characteristics of small particles (50 - 500 micrometer) with their sinking velocities in the mesopelagic environment)
Listed in Biological and Chemical Oceanography Data Management Office (BCO-DMO) ERDDAP
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).
Description
Particle images were acquired with a Focused Shadowgraph Imaging (FoSI) 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) and high-OD pools, sorted into size classes, and normalized to compute particle number spectra. Spectral slopes were compared across regions and depths using ANCOVA to assess spatial variability in particle size distributions (see listed Results Publications).
