Description
The coral reefs in the Caribbean Sea are declining at an alarming rate. This is due to a variety of factors including increased coastal development and pollution as well as effects of climate change, overfishing, and disease. Using ArcGIS ArcMap 10.1 software and Landsat data sets, the abundance of these reefs are tracked using Landsat 7 data from 2002 and Landsat 8 data from 2011. This study will use image classification to identify the Looe key reef (24.55⁰, -81.40⁰) and the Molasses reef (25.00⁰, -80.42⁰) in the Florida Keys, USA. The aim of this study is to explore the difference between Landsat 7 and Landsat 8 data scenes when identifying underwater structures, such as coral reefs. Developing methods to use Landsat data to track coral reefs could ultimately contribute to oceanic research and allow future tracking of threatened coral reef ecosystems.
