The paper presents the results of measurements of marine particles in situ during Arctic expedition using the digital holographic camera (DHC). Characteristics of various marine particles, including classification and statistics on taxa, depth profiles of plankton concentration were measured. DHC technology may be used without additional sensors to obtain additional information on the medium, such as volume content of methane according to bubble surfacing and water turbidity assessed by the screening coefficient of the suspension taxon.
