SBC LTER: Reef: Long-term experiment: Taxon-specific seasonal net primary production (NPP) for macroalgae

This dataset provides estimates of seasonal net primary production
(NPP) for all taxa of macroalgae sampled in fixed plots of the SBC
LTER's long-term kelp removal experiment sites. The experiment was
initiated in 2008 at 4 sites; a fifth site as added in 2011. Data
collection is ongoing. NPP of understory taxa was calculated using
field measurements of irradiance and biomass (derived from
abundance) and laboratory estimates of taxon-specific
photosynthetic parameters. NPP for the giant kelp,
Macrocystis pyrifera, was calculated using
linear relationships between frond density in a given season and
average NPP for that season.

本数据集提供了季节性净初级生产力（Net Primary Production, NPP）的估算值，这些估算针对SBC LTER长期海带移除实验站点（long-term kelp removal experiment sites）固定样方（fixed plots）中采样的所有大型藻类（macroalgae）类群。该实验于2008年在4个站点启动；2011年新增了第5个站点。数据采集工作仍在进行中。林下类群（understory taxa）的NPP通过野外辐照度（irradiance）和生物量（biomass，由丰度（abundance）推导）的测量值，以及实验室获得的类群特异性光合参数（taxon-specific photosynthetic parameters）估算值计算得出。巨藻（giant kelp，Macrocystis pyrifera）的NPP则通过特定季节的叶片密度（frond density）与该季节平均NPP之间的线性关系（linear relationships）计算得出。
