  abstract = {{T}he bloom-forming dinoflagellates and euglenophyceae were observed in the coastal waters of {H}ammam-{L}if ({S}outhern {M}editerranean), during a green tide event on 3 {J}une 2023. {T}he bloom was dominated by {L}epidodinium chlorophorum, identified through ribotyping with densities reaching 2.3 x 10(7) cells<middle dot>{L}-1. {E}uglena spp. and {E}utrepsiella spp. contributed to the discoloration, with abundances up to 2.9 x 10(7) cells<middle dot>{L}-1. {E}nvironmental data revealed significant depletion of nitrite and nitrate, coinciding with a rapid increase in sunlight duration, likely promoting the proliferation of {L}. chlorophorum and euglenophyceae. {B}y 5 {J}une, two days after the bloom, nutrient stocks were exhausted. {D}iatoms appeared limited by low silicate concentrations (<0.05 <mu>mol<middle dot>{L}-1), while dissolved inorganic phosphate and {N}itrogen-ammonia were elevated during the bloom (0.88 and 4.8 mu mol<middle dot>{L}-1, respectively), then decreased significantly afterward (0.23 and 1.06 mu mol<middle dot>{L}-1, respectively). {L}ow salinity (34.0) indicated substantial freshwater input from the {M}eliane {R}iver, likely contributing to nutrient enrichment and bloom initiation. {A}fter the event, phytoplankton abundance and chlorophyll levels declined, with a shift from dinoflagellates to diatoms. {T}he accumulation of pigments (chlorophyll b and carotenoids) and the presence of {M}ycosporine-like amino acids ({MAA}s) during and after the bloom suggest that {UV} radiation and {N}itrogen-ammonia were key drivers of this green tide.},
