Testing a new and accessible method for tracking changes in the abundance of giant kelp (Macrocystis pyrifera) along the Monterey Peninsula, California, USA
Abstract/Contents
- Abstract
- Subtidal video surveys are an equitable and accessible tool for research and teaching. After minimal training, these videos, conducted along underwater transects, can be analyzed by anyone, anywhere. These surveys have the potential to become an interactive teaching tool that introduces students to the scientific method in the context of subtidal ecosystems. Here, we document the methods for conducting video surveys and compare estimates of kelp density from in situ vs. video surveys. There was a significant relationship between in situ and video estimates of kelp stipe density, but on average, the videos estimated 42% of in situ density. Despite underestimating kelp density, this method easily distinguishes between forested and barren states and thus is likely to be useful in rapid assessments of kelp forests.
