At CEMarin we are pleased to share with you our annual magazine of scientific dissemination Sonar, named after the well-known tool used by dolphins, whales and other animals to navigate, communicate, and map the underwater world. 

We expect this publication to be a tool for a better knowledge and understanding of the current situation of the marine-coastal ecosystems of Colombia and beyond. Each issue includes contributions from CEMarin researchers and national and international experts who share their knowledge and experiences related to the central theme, as well as reports on ongoing research projects supported by CEMarin and updates on our activities.
