取樣方法

Point Point Contact methods photoContact sampling consists of noting the diversity and abundance of invertebrates and algae by recording what is found directly underneath or in the near vicinity of 100 points on each transect. Algae and invertebrate species, hosts and epiphytes, layering, and substrate characteristics are all taken into account. Each transect is surveyed using the point intercept method. Ideally, 100 points per transect are sampled. At each point three organisms are identified. This results in approximately 3,300 data points per site. Sampling intervals are determined based on the length of the bench. The organism that falls directly under each point is recorded first. Then the next two closest, but always different, organisms are recorded. Organisms living on another species are recorded as 'epibionts' and the organism they occur on is recorded as 'host.' Some examples of host organisms are mussels, coralline algae, barnacles, and colonial worms. If an organism under a point cannot be identified in the field, we assign it an "unknown" number and collect a sample to identify later in the lab. In 2017, we upgraded from using Palm Pilots to iPad mini's in order to expedite data recording and entry. MARINe contracted DiveNav to create an app specifically designed for the biodiversity protocol which includes regional species templates and error-checking features. Waterproof cases allow the iPads to function safely in the intertidal zone and in any type of weather. Data collected in the field are stored as CSV files and uploaded to the Coastal Biodiversity Surveys database.
