Coastal Biodiversity and Ecosystem Service Sustainability (CBESS) surface sediment colloidal carbohydrate concentration in saltmarsh and mudflat habitats

The dataset details surface sediment colloidal carbohydrate concentrations across six intertidal sites in the winter and summer of 2013. Colloidal carbohydrate concentrations in surface sediments (top 2mm) provide a quantitative measure of the extracellular polymeric substances (EPS) secreted by organisms that form the microphytobenthos (MPB) community. Three of the sites were in Morecambe Bay, North West England and three of the sites were in Essex, South East England, each of these sites consisted of a saltmarsh area and adjacent mudflat area, twenty two sampling quadrats were placed on each area. Five replicate sediment samples were taken at each quadrat and were analysed using the Dubois Phenol-Sulphuric Assay which involves spectrophotometer analysis of absorptions to determine colloidal carbohydrate concentrations. Values for colloidal carbohydrate concentrations are expressed as glucose equivalents in micrograms per gram of sediment. This data was collected as part of Coastal Biodiversity and Ecosystem Service Sustainability (CBESS): NE/J015644/1. The project was funded with support from the Biodiversity and Ecosystem Service Sustainability (BESS) programme. BESS is a six-year programme (2011-2017) funded by the UK Natural Environment Research Council (NERC) and the Biotechnology and Biological Sciences Research Council (BBSRC) as part of the UK's Living with Environmental Change (LWEC) programme.

本数据集详细记录了2013年冬季和夏季六个潮间带地表沉积物胶体碳水化合物浓度。地表沉积物（顶部2毫米）中的胶体碳水化合物浓度可作为量化由构成微植物底栖群落（MPB）的生物分泌的细胞外聚合物（EPS）的定量指标。其中三个采样点位于英格兰西北部的莫克姆湾，另外三个位于英格兰东南部的埃塞克斯，每个采样点均包含一个盐沼区域及其相邻的泥滩区域，每个区域放置了二十二个采样方格。在每个方格中采集了五个重复的沉积物样本，并使用杜波依斯酚硫酸法进行分析，该方法涉及使用分光光度计分析吸光度以确定胶体碳水化合物浓度。胶体碳水化合物浓度的数值以每克沉积物葡萄糖当量（微克）表示。此数据收集作为海岸生物多样性和生态系统服务可持续性（CBESS）项目（NE/J015644/1）的一部分。该项目得到了生物多样性和生态系统服务可持续性（BESS）计划的支持。BESS是一个为期六年的计划（2011-2017），由英国自然环境研究委员会（NERC）和生物技术与生物科学研究委员会（BBSRC）资助，作为英国“与环境共处”（LWEC）计划的一部分。有关本数据集的详细信息，请参阅https://doi.org/10.5285/6c027bf9-b344-4178-b8b3-d78cf39f017f。
