The Marine Research Institute is a subdivision of Klaipėda University, conducting fundamental and applied research on marine and coastal environment and maritime technologies. The Institute aims to facilitate science, study, and business cooperation, based on high-level scientific knowledge and the up-to-date open access research infrastructure of the Marine Valley.
A part of Marine Research Institute infrastructure was established after the Lithuanian Government (23 July, 2008, Resolution No. 786) approved The Programme of Integrated Science, Studies and Business Centre (Valley) for the Development of Lithuanian Maritime Sector with a purpose to establish and develop Marine Valley in Klaipėda.
In November 2018 the Council of Marine Research Institute confirmed the Gender Equality Action Plan for the period 2018-2023.
