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.
