Delta-X: Belowground Biomass and Necromass across Wetlands, MRD, LA, USA, 2021, V2

This dataset contains total belowground biomass (BGB) and necromass (BGN), and total carbon, total nitrogen, and total phosphorus content of samples collected from herbaceous wetlands in the Atchafalaya and Terrebonne basins of the Mississippi River Delta in southeastern coastal Louisiana, U.S., during March and August 2021. The data were collected during the Delta-X Spring and Fall deployments. Field measurements were conducted at three sites in the Atchafalaya basin and three sites in the Terrebonne basin. Five of the sites are adjacent to sites from the Coastwide Reference Monitoring System (CRMS). The other site is located in Wax Lake Delta (WLD) without appropriate adjacent CRMS sites. Herbaceous wetland sites in both basins were chosen to represent a salinity gradient including freshwater, brackish, and saline ecosystems. Root biomass samples were collected using a gouge soil auger.

本数据集涵盖了2021年3月和8月期间，于美国东南部路易斯安那州沿海阿切法拉亚河三角洲的阿切法拉亚河和特雷布恩河盆地草本湿地中收集的样品的总地下生物量（BGB）和腐殖质（BGN），以及总碳、总氮和总磷含量。数据收集于Delta-X春季和秋季部署期间。实地测量在阿切法拉亚盆地的三个地点和特雷布恩盆地的三个地点进行。其中五个地点与海岸参考监测系统（CRMS）的地点相邻。另一个地点位于瓦克斯湖三角洲（WLD），该地点附近没有合适的CRMS相邻地点。两个盆地的草本湿地地点均被选中以代表盐度梯度，包括淡水、半咸水和咸水生态系统。根生物量样品使用挖孔土壤钻头收集。
