PIE LTER eddy flux measurements during 2015 from second high marsh site (Spartina patens/short Spartina alterniflora) Tall Tower off Nelson Island Creek, Rowley, Massachusetts

We deployed an eddy covariance system to measure ecosystem-atmosphere exchange of CO2  above a high marsh system (Spartina patens, short Spartina alterniflora) located on the Parker River Wildlife Refuge in marshes of Plum Island Sound, Rowley MA. The system is located near a higher elevation rock outcropping protected area which allows the tower set up to remain during the Winter as it is protected from ice flows. The data represents CO2 exchange for all 12 months of 2015.

本研究于美国马萨诸塞州罗利市普拉姆岛湾沼泽的帕克河野生动物保护区内的高潮滩湿地系统（狐米草*Spartina patens*、短型互花米草*Spartina alterniflora*）上方部署涡度协方差系统（eddy covariance system），用于测定生态系统与大气间的二氧化碳交换通量。该系统设置于一处高海拔裸露岩丘保护区域附近，观测塔架设结构可在冬季留存，免受浮冰流动的破坏。本数据集涵盖2015年全年12个月的二氧化碳交换观测数据。
