SBC LTER: Beach: Wrack and porewater in southern Santa Barbara County, 2003

These data describe 1) the composition, cover, and wet biomass of macrophyte wrack accumulated in the intertidal zone measured along replicated shore-normal transects and 2) the concentrations of major dissolved nutrients and salinity of samples of beach porewater collected from excavations to the water table at different intertidal heights and in the surf zone along the same replicated transects where wrack was measured. These wrack and biogeochemical data were collected on ten sandy beaches of the mainland coast of the Santa Barbara Channel in late summer 2003. Distance between shore-normal transects was randomly selected at each site, and data can be used as replicates

本数据集包含两类观测数据：
1) 沿重复布设的垂直岸线样带（shore-normal transects）采集的潮间带（intertidal zone）堆积大型植物碎屑（macrophyte wrack）的组成、覆盖度与湿生物量；
2) 沿上述开展大型植物碎屑测量的相同重复样带，在不同潮间带高度处开挖至潜水位（water table）采集的海滩孔隙水（beach porewater）样品，以及冲浪区（surf zone）海滩孔隙水样品中的主要溶解态营养盐浓度与盐度。
上述大型植物碎屑与生物地球化学数据采集于2003年夏末圣巴巴拉海峡（Santa Barbara Channel）大陆沿岸的10处砂质海滩。各站点的垂直岸线样带间距为随机选定，所得数据可作为重复样本使用。
