    Alkenones in the Mediterranean Sea (1996)
    PANGAEA
    In:  Supplement to: Ternois, Yann; Sicre, Marie-Alexandrine; Boireau, Anne; Marty, Jean-Claude; Miquel, Juan Carlos (1996): Production pattern of alkenones in the Mediterranean Sea. Geophysical Research Letters, 23(22), 3171-3174, https://doi.org/10.1029/96GL02910

    Beschreibung: Time-series of downward alkenone fluxes have been investigated at 200 m depth over a one year sediment trap experiment, in the Northwestern Mediterranean Sea. Alkenone flux maxima occurred in autumn and to a lesser extent in May, during the spring bloom. Temperature estimates calculated from the UK'37 index revealed that alkenone producers preferentially develop in subsurface waters (at about 50 m) in spring, whereas the autumn alkenone production occurred upper in the water column (around 30 m). Examination of the core-top UK'37 index values at various sites of the Northwestern Mediterranean basin, suggested that the spring bloom period do not significantly imprint the temperatures recorded in the sediments. The sedimentary temperature estimates would rather reflect annually integrated SST, with a major influence of the autumnal post-bloom development of the coccolithophores in the euphotic zone.

    Hydrocarbons, sterols and alkenones at time series station KERFIX (1998)
    PANGAEA
    In:  Supplement to: Ternois, Yann; Sicre, Marie-Alexandrine; Boireau, Anne; Beaufort, Luc; Miquel, Juan Carlos; Jeandel, Catherine (1998): Hydrocarbons, sterols and alkenones in sinking particles in the Indian Ocean sector of the Southern Ocean.

    Beschreibung: Hydrocarbons, sterols and alkenones were analyzed in samples collected from a 10 month sediment trap time series deployed in the Indian Ocean sector of the Southern Ocean. Fluxes and within-class distributions varied seasonally. During higher mass and organic carbon (OC) flux periods, which occurred in austral summer and fall, fresh marine inputs were predominant. Vertical fluxes were most intense in January, but limited to one week in duration. They were, however, low compared with other oceanic regions. In contrast, low mass and OC flux periods were characterized by a strong unresolved complex mixture (UCM) in the hydrocarbon fraction and a high proportion of stanols as a result of zooplanktonic grazing. Terrigenous inputs were not detectable. The alkenone compositions were consistent with previous data on suspended particles from Antarctic waters. However, UK'37 values diverged from the linear and exponential fits established by Sikes et al. (1997, doi:10.1016/S0016-7037(97)00017-3) in the low temperature range. The seasonal pattern of alkenone production implied that IPT (integrated production temperature) is likely to be strongly imprinted by austral summer and fall SST (sea surface temperature).
