Since 1991, TTR has been actively involved into multi-disciplinary deep-sea geoscience studies. Apart from cruises, the research includes data processing in leading universities and laboratories of countries involved. Several hundred research papers have been published by the cruises' participants in international peer-reviewed journals in addition to special issues of Marine Geology (#132, 1996) and Geo-Marine Letters (#18, 1998). The cruise scientific reports, proceeding of the TTR conferences and annual reports have regualrly been published  by the IOC and UNESCO.
