Alkenone determination from sediment core TAN1106/28
Over the last deglaciation there were two transient intervals of pronounced atmospheric CO2 rise; Heinrich Stadial 1 (17.5-15 kyr) and the Younger Dryas (12.9-11.5 kyr). Leading hypotheses accounting for the increased accumulation of CO2 in the atmosphere at these times invoke deep ocean carbon bein...

Over the last deglaciation there were two transient intervals of pronounced atmospheric CO2 rise; Heinrich Stadial 1 (17.5-15 kyr) and the Younger Dryas (12.9-11.5 kyr). Leading hypotheses accounting for the increased accumulation of CO2 in the atmosphere at these times invoke deep ocean carbon being released from the Southern Ocean and an associated decline in the global efficiency of the biological carbon pump. From core TAN1106-28 we present new deglacial alkenone and n-alkane records. Analysis and characterization of total lipid content were performed at Institut de Ciències del Mar in Barcelona following published methods (Villanueva et al., 1997; doi:10.1016/S0021-9673(96)00669-3, Calvo et al., 2003; doi:10.1016/S0021-9673(03)00119-5, Kornilova and Rosell-Melé, 2003; doi:10.1016/S0146-6380(03)00155-4) on an Agilent 7890 Gas Chromatograph with a flame ionization detector equipped with a HP-1 capillary column (60 m, 0.25 mm I.D. and 0.25 µm film thickness). |
