Abstract

Covid-19 lockdowns reduced boat-based tour activities to the Biological Reserve of Caño Island, Costa Rica during 2020. Caño Island is one of the most popular tour destinations in Costa Rica due to its proximity to the mainland and diverse marine life. The purpose of this research is to determine how COVID-19 lockdowns impacted the soundscape of this protected area. Autonomous underwater recorders were deployed in September 2019 and 2020 to record the soundscape of Caño Island. We created a presence-absence matrix to look at boat presence and use RFCxArbimon soundscape analytical tools to generate a matrix of acoustic events by time of day and frequency bin. We hypothesized that a decrease in boat traffic will result in an increase of biological sound sources. By studying the effects of boat traffic and noise pollution on marine ecosystems such as the Caño island biological reserve, we can better understand what these protected ecosystems need in order to thrive.
