A presentation given by Tatiana Becker during an activity of the KIVI Kring Caribbean – Aruba at the University of Aruba highlighted how to get spatial environmental data in a relatively simple and cheap way. This is especially valuable for Small Island Development States (SIDS) like Aruba which are lacking financial resources for environmental monitoring. Surfside Science, a project piloted at the Surfside Beach of Aruba, demonstrated this and the results are there. The seafloor maps generated from classifying satellite data were tested for their accuracy via GPS-tracked photographic surveys that were conducted with the help of divers from ScubbleBubble foundation on Aruba (ScubbleBubble is a non-profit foundation that focuses on getting local youth of the Aruban community involved in ocean conservation activities). Comparing these two sources of data, the satellite-based seafloor maps have been validated. Before the satellite data was validated,
Tatiana Becker developed a classification system to standardize the photo classification/ interpretation process. The accuracy of this validation was about 60.5% which is considered a moderate accuracy. It was demonstrated to have a higher accuracy and or precision than existing seafloor maps for the area. Furthermore, the data collected are transparently accessible at the data portal Data Portal (brenchies.com) One can make their own trend analysis using these data.
More information about low-cost methods used to monitor a range of environmental parameters like air quality, water quality and the reef island coverage can be found on Surfside Science – Exploring replicable methods for coastal environmental monitoring (brenchies.com)
