Abstract
Marine mammals can be adversely affected by anthropogenic sound sources, so mitigation efforts are regularly implemented to reduce the risk to mammals during active-sonar activities. Mitigation efforts can be more effective if prior knowledge of the marine-mammal population in the area is known. This contractor report summarizes Akoostix’s effort to develop a database of marine-mammal activity in the waters around Nova Scotia, and includes analysis of existing data sets and identification of potential sources of more data that have either already been collected or could be collected in the future. It was found that the readily available data sets have very sparse coverage, and much more data is required to complete a comprehensive database for this area. A database structure has been designed and the existing observations have been inserted into the database. Notes on these experiments are provided herein, while additional detail is available in Software Tools for Analysis and Research (STAR)-formatted trial archives.
