SBCLTER: Beach: Beach Wrack CHN

The purpose of monthly wrack CHN sampling is to track the carbon, hydrogen, and nitrogen concentrations in old and new Macrocystis pyrifera blades and stipe at SBC LTER beach sites over time. Ten to twenty M. pyrifera new blades, new stipes, old blades, and old stipes are collected at each of five beach sites once a month. A samples of the blades and stipes are processed and run through an Organic elemental analyzer, using the combustion method. This data collection program began in October 2008 and is ongoing.
