The Coastal Ocean Environment Summer School in Ghana is an international collaboration aimed at building capacity in oceanographic and environmental sciences in Ghana.  A long-term goal of the school is to increase the presence of African scientists at international science meetings.  Summer schools have been held every year from 2015 to 2020. Pending successful funding efforts, we will continue to hold summer schools in 2021 and beyond.  We have built links with institutions in Ghana and other African countries, and have incorporated research partnerships into the summer school. The school has also expanded to include small group research projects throughout the week.
