I research the fates and uses of grazed kelp and kelp detritus within kelp forests both in northeastern New Zealand and within the Santa Barbara Coastal LTER site. To do so, I run field and lab experiments and I measure natural abundances of fatty acids, and carbon and nitrogen isotopes for work with biomarkers. I’ve directly measured small particle kelp sloughing rates to measure availability of kelp detritus to subtidal suspension feeders. I’m currently working on measuring suspension feeder utilization of kelp detritus, both through natural sloughing availability and through urchin modulated bioavailability.
