    Description: The sea-surface microlayer (SML) at the boundary between atmosphere and hydrosphere represents a demanding habitat for bacteria. Wind speed is a crucial but poorly studied factor for its physical integrity. Increasing atmospheric burden of CO2, as suggested for future climate scenarios, may particularly act on this habitat at the air-sea interface. We investigated the effect of increasing wind speeds and different pCO2 levels on SML microbial communities in a wind-wave tunnel, which offered the advantage of low spatial and temporal variability. We found that enrichment of bacteria in the SML occurred solely at a U10 wind speed of 〈=5.6 m/s in the tunnel and 〈=4.1 m/s in the Baltic Sea. High pCO2 levels further intensified the bacterial enrichment in the SML during low wind speed. In addition, low wind speed and pCO2 induced the formation of a distinctive bacterial community as revealed by 16S rRNA gene fingerprints and influenced the presence or absence of individual taxonomic units within the SML. We conclude that physical stability of the SML below a system-specific wind speed threshold induces specific bacterial communities in the SML entailing strong implications for ecosystem functioning by wind-driven impacts on habitat properties, gas-exchange and matter cycling processes.

    Distribution of pharmaceutical compounds in coastal waters of the North Sea in March 2023 (2023)
    PANGAEA
    Details
    Publication Date: 2024-01-15
    Description: We investigated the occurrence, spatial, and vertical distributions of 63 pharmaceutical compounds and six artificial sweeteners from the sea surface microlayer (SML) to five different depths (0 cm, 20 cm, 50 cm, 100 cm, and 150 cm) of the corresponding underlying waters in four stations of the North Sea. One station is a coastal area (Jade Bay), one station is an estuary (Bremerhaven), and the other two stations (NS_7 and NS_8) are open coastal waters. We will refer to each environment with the name in brackets throughout this publication. We collected seawater samples vertically from these stations and analyzed them using ultra-performance liquid chromatography - triple quadrupole mass spectrometry in tandem with ionization spray (UPLC-QqQMS/MS) (Bruker EVOQ Elite system Bruker, USA) at the Department of Physical Chemistry, University of Cádiz.
