Field Technique Training Students will be competitive in the field of marine science if they obtain training and experience in some of the basic field sampling methods. We train students in a variety of techniques as part of every field course. These skills can also be taught as workshops or seminars. Belt Transects Some of the more common sampling methods involve the use of belt transects. We start by training students on land to simulate the length, width and timing of the transect. We then practice the skill at shallow reef sites accessible to both divers and snorkelers. 9 Reef Fish Identification Quadrats We are the only company offering a unique training opportunity in Caribbean fish identification. We have developed an "app" to teach fish ID while underwater using tablet technology. Your students will be among the first to use this innovative educational app. Quadrats are often used to sample benthic habitat to determine percentage cover of the substrate. We teach students how to construct their own quadrat then demonstrate how to properly set up and collect data using this simple and functional tool. Data Analysis Coral Reef Complexity Part of field training also includes understanding how to analyze the collected data. We teach students the basics of using free software like Coral Point Count to determine percent cover from their quadrat photos. We also instruct in the use of Image J for reef rugosity. Rugosity of the reef is a measurement that is often taken simultaneously as reef slope. Both of these measurements provide an estimate of the complexity of the reef habitat. We teach two methods to measure rugosity, plus basic photography for capturing slope. 10
