In this issue of Oceanography we have 10 papers that will introduce readers to the fascinating and exciting research that is being conducted in the Black Sea. I wrote my first Black Sea paper in 1973 with new data from the 1969 Atlantis II expedition. This started my long-term interest in the oceanography of this sea, which I have been able to pursue through organizing major research cruises in 1988, 2001, 2003, and 2005. The Black Sea has repeatedly given me opportunities to study major ocean processes in a unique environment. As a result, I have had the opportunity to develop friendships with many scientists from countries in the Black Sea region and this has lead to productive research collaborations.
