Benthos monitoring in the intertidal mudflats of Pertuis-Charentais (Bay of Biscay) from 2004 on

Benthos-Pertuis-Charentais is a spatially explicit benthic database, comprising 11 years of benthic data. It is the result of intensive benthic sampling that has been conducted on a regular grid (259 stations) covering the intertidal mudflats of the Pertuis-Charentais (Marennes-Ole'ron Bay and Aiguillon Bay). Samples were taken by foot or by boats during winter depending on tidal height, from December 2003 to February 2014. The present dataset includes abundances and biomass densities of all mollusc species of the study regions and principal polychaetes as well as their length, accessibility to shorebirds, energy content and shell mass when appropriate and available. This database has supported many studies dealing with the spatial distribution of benthic invertebrates and temporal variations in food resources for shorebird species as well as latitudinal comparisons with other databases.

本海床数据库 Benthos-Pertuis-Charentais 具有空间解析度，累积了为期11年的海床数据。该数据库源于对 Pertuis-Charentais 间歇性滩涂（Marennes-Ole'ron 湾与 Aiguillon 湾）进行的密集型海床采样，采样站点分布在一个规则的网格（共259个站点）上。采样活动根据潮汐高度，于2003年12月至2014年2月间，通过步行或乘船进行。当前数据集涵盖了研究区域中所有软体动物物种以及主要环节动物的数量和生物量密度，同时记录了其长度、对岸鸟类的可接近性、能量含量及壳体质量，当数据可用时。该数据库为众多研究提供了支持，涉及底栖无脊椎动物的空间分布、岸鸟物种食物资源的时序变化，以及与其他数据库的纬度比较。
