      abstract     = {In the ocean, breaking waves generate airbubbles which
                      burst at the surface and eject sea spray aerosol(SSA),
                      consisting of sea salt, biogenic organic species, andprimary
                      biological aerosol particles (PBAP). Our
                      overallunderstanding of atmospheric biological particles of
                      marineorigin remains poor. Here, we perform a control
                      experiment,using an aerosol time-of-flight mass spectrometer
                      to measurethe mass spectral signatures of individual
                      particles generated bybubbling a salt solution before and
                      after addition ofheterotrophic marine bacteria. Upon
                      addition of bacteria, animmediate increase occurs in the
                      fraction of individual particlemass spectra containing
                      magnesium, organic nitrogen, andphosphate marker ions. These
                      biological signatures areconsistent with $21\%$ of the
                      supermicrometer SSA particles generated in a previous study
                      using breaking waves in an oceanatmospherewave channel.
                      Interestingly, the wave flume mass spectral signatures also
                      contain metal ions including silver, iron,and chromium. The
                      nascent SSA bioparticles produced in the wave channel are
                      hypothesized to be as follows: (1) whole orfragmented
                      bacterial cells which bioaccumulated metals and/or (2)
                      bacteria-derived colloids or biofilms which adhered to
                      themetals. This study highlights the potential for
                      transition metals, in combination with specific biomarkers,
                      to serve as uniqueindicators for the presence of marine
                      PBAP, especially in metal-impacted coastal regions.},
