“…Median values of these three variables are considered as "very high" for natural soils (Cobertera, 1993). When comparing these results to other researches worldwide, it can be drawn that the soluble nutrient content in the topsoils of TDNP is similar to that in organic soils of other disturbed wetlands (Koerselman et al, 1993;Mesnage et al, 2002;Aldous et al, 2005;Tiemeyer et al, 2007;Zhang et al, 2008), and often higher than that in agricultural or forest areas (González et al, 2007;Esteller et al, 2009;Fernández et al, 2009;Lamparter et al, 2009;Miralles et al, 2009;Momtaz et al, 2009;Romanyà and Rovira, 2009;Wang et al, 2009a,b).…”

“…Paying attention to this wetland degradation, UNESCO has fixed a deadline in year 2015 to achieve the ecosystem restoration; otherwise it will be withdrawn from Biosphere Reserve status. However, the case of TDNP is not an isolated one, as similar degradation processes have happened in other wetlands worldwide too (Johnston, 1994;Mitsch and Gosselink, 2000;Mesnage et al, 2002;Aldous et al, 2005;Rudolph et al, 2005).…”

“…Historically, water drained from the Grand-Mare through these channels toward the estuary; however, several centuries of drainage to improve accessibility and facilitate agriculture have led to the subsidence of the peat bog and a reversal of flow toward the Grand- Mare. Before 1950, unrestricted drainage from the Grand-Mare to the Seine occurred by way of the Saint Aubin Canal (Mesnage et al 2002). During summer dry periods, the shallow Grand-Mare (about 0.4 m deep over most of the area) partially dried, a condition exacerbated by lowering of water levels in the Marais Vernier for agriculture.…”

“…Repairs were made in 2002 to prevent leakage. Input of sediment from the Seine via the canal has been implicated in increased sedimentation and increased nutrient loading to the Grand-Mare (Mesnage et al 2002).…”

International audienceThe Marais Vernier is the largest freshwater wetland in the Seine Estuary in northern France. It is in a heavily urbanized and industrialized region and could be affected by atmospheric deposition and by fluvial input of contaminants in water diverted from the Seine River. To evaluate contaminant histories in the wetland and the region, sediment cores were collected from two open-water ponds in the Marais Vernier: the Grand-Mare, which was connected to the Seine by a canal from 1950 to 1996, and the Petite Mare, which has a small rural watershed. Diversions from the Seine to the Grand-Mare increased sedimentation rates but mostly resulted in low contaminant concentrations and loading rates, indicating that the sediment from the Seine was predominantly brought upstream by tidal currents from the estuary and was not from the watershed. Atmospheric sources of metals dominate inputs to the Petite Mare; however, runoff of metals from vehicle-related sources in the watershed might contribute to the upward trends in concentrations of Cr, Cu, and Zn. Estimates of atmospheric deposition using the Petite Mare core are consistent with measured deposition in the region and are mixed (similar for Hg and Pb; larger for Cd, Cu, and Zn) compared with deposition estimated from sediment cores in the northeastern United States. A local source of PAHs in the watershed of the Petite Mare is indicated by higher concentrations, higher accumulation rates, and a different, more petrogenic, PAH assemblage than in the Grand-Mare. The study illustrates how diverse sources and transport pathways can affect wetlands in industrial regions and can be evaluated using sediment cores from the wetland ponds

“…How ever, a gen eral and in ter na tion ally ac cept able frame work has still not been es tab lished and the mech a nism of cli mate change remains un clear (Lis ter et al, 1991;Wang, 2005;Herzschuh et al, 2006;Wu et al, 2007;Zhao et al, 2008;Liu et al, 2010;Bian et al, 2011).

Geo log i cal Quar terly, 57 (2): 261-268, doi: 10.7306/gq.1096 This study pro vides a veg e ta tion and cli mate his tory of an al pine wet land in the cen tre of China's Qinghai-Ti betan Pla teau (QTP) over the last 14.8 ka. High res o lu tion cli mate prox ies in clude veg e ta tion (pol len), geo chem i cal (Ba, Rb, d 13 C) and phys i cal (par ti cle size and mag netic sus cep ti bil ity) data; op ti cally stim u lated lu mi nes cence (OSL) and AMS ra dio car bon dating were used to re con struct the en vi ron men tal changes in the wet land eco sys tem. Based on phys i cal and geo chem i cal prox ies, the sucession di vided into five strati graphic units en com pass ing time in ter vals of 14. 76-14.31, 14.31-13.17, 13.17-4.47, 4.47-0.51 and 0.51-0 ka. The av er age sed i men ta tion rate of all these units was 0.098 mm/a. The study showed that this eco sys tem was sen si tive to cli mate change.
