The facility is now under new management by Field Studies Council Scotland following a partnered investment of more than £4m.
Now known as FSC Millport, the station had been threatened with closure in 2012 when the previous owners – University of London – said it was withdrawing its funding.
Cabinet Secretary for Education and Lifelong Learning Michael Russell attended the official opening. He said: "I am delighted to be able to return to Millport once again and meet the staff and students in such positive circumstances. Since the announcement of the closure in 2012, all of the partners – The Field Studies Council, North Ayrshire Council, Highlands and Islands Enterprise and the Scottish Funding Council – have worked tirelessly with us to ensure that this invaluable educational and research facility was not lost.
"Generations of school and university students have been taught at this facility and it is heartening that this excellent work will continue so that many more people can experience the residential classes and unique outdoor activities provided here."
Robert Lucas, FSC Chief Executive Officer, added: "The investment in Millport ensures a new and sustainable future for the centre, building on its international reputation for marine science field teaching.
"We will be using all of our experience to provide exciting outdoor learning opportunities for people of all ages. The centre is also ideally located to act as a base for research on the Clyde Basin, and later this year will be hosting a research seminar.
"Today marks an important step for FSC in cementing our commitment to research and education in Scotland and maximising passion and understanding of the biodiversity and landscape."
