Eukaryotic community composition in the sea surface microlayer across an east–west transect in the Mediterranean Sea

Abstract: Abstract. The sea surface microlayer (SML) represents the boundary layer at the air–sea interface. Microbial eukaryotes in the SML potentially influence air–sea gas exchange directly by taking up and producing gases and indirectly by excreting and degrading organic matter, which may modify the viscoelastic properties of the SML. However, little is known about the distribution of microbial eukaryotes in the SML. We studied the composition of the microbial community, transparent exopolymer particles and polysacc… Show more

“…In general, TEP abundance in oligotrophic parts of the ocean is low (Engel et al, 2020). Values observed during this study are comparable to earlier findings for the ultra-oligotrophic parts of the Mediterranean Sea (Zäncker et al, 2021). Overall, TEP concentration measured as covered area per liter and number of particles per liter showed a positive correlation (r s(108) =0.66, p <0.01).…”

“…The SML has been considered an "extreme" habitat influenced by high solar radiation, wind-wave interaction, accumulation of pollutants, sudden changes in temperature and salinity, contact to rainfall and depositions from the atmosphere, among other parameters [3][4][5][6][7][8]. While abundance, diversity and function of eukaryotes, bacteria, and archaea [9][10][11][12] have been studied in the SML, little is known about residing viruses (reviewed by Rahlff [13]). This is particularly true for the SML within natural surface slicks.…”

“…To date, an increasing number of studies are reporting the presence of chytrids in the marine environment [21,80,84,[94][95][96][97][98], but a limited number have been properly identified and characterized [21]. These are species of Rhizophydium [99], Thalassochytrium [100] and Chytridium [101], which are either facultative or obligate parasites of macro-algae and invertebrates but diatoms (Table 1) [102,103].…”
