Macroalgae and seagrass biomass and diversity across the Pilbara Region in November 2013 and May 2014

As part of the Pilbara Marine Conservation Partnership (PMCP), coral reef surveys of reef macroalgae species (including seagrasses) were undertaken between northern Ningaloo and the Dampier Archipelago.This dataset contains biomass estimates (g DW m-2 and g WW m-2) of macrophytes collected in shallow reef areas in the Pilbara region during two sampling trips: November 2013 and May 2014. Surveys were undertaken using using SCUBA at depths between 2-13m, with macroalgae and seagrasses identified to the lowest possible taxonomic level. The data include:* Macroalgae and seagrass diversity (0.25 square metre quadrats)* Macroalgae and seagrass species composition and biomass per quadrat (0.25 square metre)These data were collected to estimate macrophyte biomass in shallow reef areas across the Pilbara region in two contrasting seasons.These data are an output of the Pilbara Marine Conservation Partnership (PMCP) Coral Reef Health Theme.

作为皮尔巴拉海洋保护伙伴关系（Pilbara Marine Conservation Partnership, PMCP）的项目组成部分，研究团队于宁格罗北部至丹皮尔群岛海域开展了珊瑚礁大型藻类（含海草）调查。本数据集包含2013年11月与2014年5月两次采样航次期间，在皮尔巴拉海域浅礁生境采集的大型水生植物（macrophytes）生物量估算数据，单位为克干重每平方米（g DW m⁻²）与克鲜重每平方米（g WW m⁻²）。本次调查采用水肺潜水（SCUBA）技术开展，作业水深范围为2至13米，所有大型藻类与海草均鉴定至最精细的分类学层级。数据集包含以下内容：
1. 大型藻类与海草多样性数据（基于0.25平方米样方（quadrat）采集）
2. 单0.25平方米样方内的大型藻类与海草物种组成及生物量数据
本次数据采集的核心目标为针对皮尔巴拉全域浅礁生境，在两个季节特征差异显著的时段开展采样，以估算大型水生植物生物量。本数据集为皮尔巴拉海洋保护伙伴关系（PMCP）珊瑚礁健康主题的研究产出成果。
