Nutrient concentration and density data; A Canadian Healthy Oceans Network Ecosystem Function Project, EF-03

Excel file with all nutrient concentrations determined in laboratory from sediment samples as well as bivalve densities from Tier I & II experiments. NA denotes samples that were not collected or missing due to procedural errors in laboratory. Blank cells are outliers that have been removed from statistical analysis. Tier III abbreviations are as follows: s = sterilized treatments; sv = sterilized treatments + varnish clams; us = unsterilized treatments; usv = unsterilized treatments + varnish clams.

本数据集为Excel格式文件，涵盖实验室测定的沉积物样品全部营养盐浓度，以及一级（Tier I）与二级（Tier II）实验中的双壳类密度数据。其中NA代表因实验室操作流程失误未采集或缺失的样品。空白单元格为已从统计分析中剔除的异常值。三级（Tier III）实验的缩写含义如下：s = 灭菌处理组；sv = 灭菌处理组+光泽蛤（varnish clams）；us = 未灭菌处理组；usv = 未灭菌处理组+光泽蛤（varnish clams）。
