AmeriFlux FLUXNET-1F US-WPT Winous Point North Marsh

This is the AmeriFlux Management Project (AMP) created FLUXNET-1F version of the carbon flux data for the site US-WPT Winous Point North Marsh. This is the FLUXNET version of the carbon flux data for the site US-WPT Winous Point North Marsh produced by applying the standard ONEFlux (1F) software. Site Description - The marsh site has been owned by the Winous Point Shooting Club since 1856 and has been managed by wildlife biologists since 1946. The hydrology of the marsh is relatively isolated by the surrounding dikes and drainages and only receives drainage from nearby croplands through three connecting ditches. Since 2001, the marsh has been managed to maintain year-round inundation with the lowest water levels in September. Within the 0–250 m fetch of the tower, the marsh comprises 42.9% of floating-leaved vegetation, 52.7% of emergent vegetation, and 4.4% of dike and upland during the growing season. Dominant emergent plants include narrow-leaved cattail (Typha angustifolia), rose mallow (Hibiscus moscheutos), and bur reed (Sparganium americanum). Common floating-leaved species are water lily (Nymphaea odorata) and American lotus (Nelumbo lutea) with foliage usually covering the water surface from late May to early October.

本数据集为美国通量网管理项目（AmeriFlux Management Project, AMP）针对US-WPT维努斯角北沼泽（Winous Point North Marsh）站点构建的FLUXNET-1F版本碳通量数据。本数据集为通过标准ONEFlux（1F）软件处理得到的US-WPT维努斯角北沼泽站点碳通量数据的FLUXNET版本。站点概况——该沼泽自1856年起归维努斯角狩猎俱乐部（Winous Point Shooting Club）所有，自1946年起由野生生物学家开展管理工作。该沼泽的水文系统被周边堤坝与排水沟相对隔离，仅通过三条连通沟渠接收附近农田的排水。2001年以来，该沼泽被调控为全年保持淹水状态，且于9月维持最低水位。在观测塔0~250米的通量贡献区范围内，生长季内该沼泽的植被构成如下：浮叶植被占比42.9%，挺水植被占比52.7%，堤坝与高地占比4.4%。优势挺水植物包括狭叶香蒲（Typha angustifolia）、玫瑰锦葵（Hibiscus moscheutos）与美洲黑三棱（Sparganium americanum）。常见浮叶植物包括香睡莲（Nymphaea odorata）与美洲莲（Nelumbo lutea），其叶片通常于5月下旬至10月上旬覆盖水面。
