Sea-spray aerosol (SSA) plays a crucial role in climate processes by influencing radiative forcing, cloud formation, and precipitation. While SSA particles with diameters between 0.1 10 μm are commonly studied, larger aerosols (>20 μm) have been observed over terrestrial oceanic regions but generally overlooked. Large bioaerosols can be formed pollen, fungal spores, cell debris. However, the abundance, dynamics, composition of large marine remain poorly understood. This study wave atmospheric conditions driving production, resulting sizes (up to 90 μm), collected collocated samples for microscopy analysis during two-month time period. above 20 were frequently observed, containing diverse range intact phytoplankton cells, including small flagellates (2 diatoms, colonial cells (above 40 μm).

To best our knowledge, this is first evidence direct airborne observation (rather than deposition) cells. These findings highlight ubiquity their capacity carry
