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

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.

本海带碳氢氮元素月度采样项目，旨在长期追踪SBC LTER站点内巨藻（Macrocystis pyrifera）组织中的碳、氢、氮元素浓度。研究团队每月于三个珊瑚礁站点各采集15片巨藻叶状体，采样位置选取自多株巨藻生长端约2米处。采集的叶状体将被制备为芯样，采用燃烧法上机，通过有机元素分析仪（Organic elemental analyzer）完成元素组分检测。详细信息请参见方法章节。
