| 520 | _ | _ | |a The seasonal evolution of chemical and physical water properties as well as particle fluxes was monitored in Sacrower See (northern Germany) during two consecutive years (Oct 2003 - Oct 2005). Additonally, we measured delta O-18 and delta C-13 as well as Sr:Ca and Mg:Ca ratios of authigenic calcites that were collected in sequencing sediment traps in order to disentangle environmental and climatic factors controlling these parameters. In particular, our aim was to find out if element ratios and the isotopic composition of calcites reflect changes, in water and air temperatures. Lake water is highly enriched in O-18 (-1.3 to -2.5%. VSMOW) with an evaporative increase of 0.6 parts per thousand during summer. Values are 5-6 parts per thousand more positive than groundwater values and 4-5 parts per thousand more positive than long-term weighted annual means of precipitation. During spring and summer, high amounts of dissolved phosphate cause eutrophic conditions and calcite precipitation in isotopic disequilibrium. Measured values are depleted in 180 by 2 to 10 parts per thousand compared to calculated equilibrium values. Resuspension and partial dissolution of calcite in the water column contribute to this isotopic divergence in summer and autumn as delta O-18(ca) and delta C-13 values increased in the hypolimnion during this time. Mg:Ca and Sr:Ca ratios are altered by dissolution as well. In the hypolimnion these ratios were higher than in the epilimnion. Another reason for the huge deviation between measured and theoretical delta O-18(ca) values during summer is the occurrence of large amounts of Phacotus lenticularis in the carbonate - fraction. High amounts of Phacotus lead to more negative delta O-18(ca) and more positive delta C-13 values. Several characteristics of delta O-18(ca) and delta C-13 are also reflected by Mg:Ca and Sr:Ca ratios and isotopic composition of oxygen and carbon were influenced by the onset and stability of stratification. Especially the earlier onset of stratification it? 2005 caused higher sediment fluxes and more positive carbon and oxygen isotope values of bioinduced carbonates compared to 2004. |
