SBC LTER: Reef: Macrocystis pyrifera CHN content (carbon, hydrogen, nitrogen), ongoing since 2002

The purpose of monthly kelp CHN sampling is to track the carbon,
hydrogen, and nitrogen concentrations in Macrocystis
pyrifera tissue at SBC LTER sites over time. A total of
fifteen M. pyrifera blades are collected at
each of three reef sites once a month. Blades are selected
approxiamtely two meters from the growing end of several different
plants. Core samples of the blades are processed and run through an
Organic elemental analyzer with a combustion method. See Methods for more information.

本月度海带碳氢氮（CHN）采样工作旨在长期追踪SBC LTER站点内巨藻（Macrocystis pyrifera）组织中的碳、氢、氮浓度变化。研究人员每月从3个礁体样地的每个站点采集15片M. pyrifera叶片，所选叶片均取自多株不同巨藻的生长端约2米处。随后对叶片的核心样品进行前处理，并采用燃烧法通过有机元素分析仪开展检测分析。详细实验流程参见方法部分。
