Data for manuscript: Water motion influences carbon-use strategies of kelp forest assemblages and defines responses of macroalgae to ocean acidification

A field dataset detailing the abundance and carbon use strategies (obtained with C13 isotopes) of marine macroalgae within 3 wave-exposed and 4 wave-sheltered coastal kelp forests in Otago, New Zealand, along with site information such as temperature, light, nutrients of each site.<br>Additionally, a dataset of the results from a laboratory experiment measuring the photosynthetic response of <em>Xiphophora gladiata </em>and <em>Hymenena palmata </em>to increasing DIC concentrations and under high or low water motion and high (8.1) or low (7.6) pH.

本野外数据集详细记录了新西兰奥塔哥地区3处波浪暴露型与4处波浪庇护型沿岸海带林内海洋大型海藻的物种丰度与碳利用策略（采用碳13同位素（C13 isotopes）方法测定），同时配套提供各实验样地的温度、光照及水体营养盐等环境参数信息。
此外，本数据集还包含一项室内控制实验的结果：该实验测定了<em>Xiphophora gladiata</em>与<em>Hymenena palmata</em>在溶解无机碳（Dissolved Inorganic Carbon, DIC）浓度梯度升高、不同水流条件（高/低水流）以及高pH（8.1）、低pH（7.6）环境下的光合响应。
