This series of Conferences started in 2005 by Leif Bjorno and John S. Papadakis under the title UAM - ‘Underwater Acoustic Measurements: Technologies and Results’, (Heraklion in 2005 and 2007 – Nafplion in 2009 – Kos in 2011). In 2013, UAM was merged with ECUA and the title changed to UACE- ‘Underwater Acoustics Conference and Exhibition’, (Corfu in 2013, Rhodes in 2014 and Chania in 2015).

    In October 2015, Leif Bjorno passed away. I felt that I should continue with the organization so I asked the assistance of the good friends and colleagues Philippe Blondel, David Bradley, Mike Buckingham, Ross Chapman, Qihu Li and Michael Taroudakis to form an Organizing Committee and help with the organization of the Conference in Skiathos island in 2017.

    At that Conference, David Bradley accepted the task to be my Co-Chairman. Together, we organized the 2019 Conference in Hersonissos, Crete.

    In 2021, the UACE will be held in Kalamata, Peloponnese, 20-25/6/2021, at the Filoxenia Kalamata Hotel. In 2021 we are celebrating the 10th Conference of the series.

    UACE2021 will continue the Competition on the best paper presented by graduate students, Prof. Leif Bjorno Award. A new award for the best paper presented by a young scientist up to 40 years old will be initiated. Both awards will be funded by The Institute of Computational and Applied Mathematics of the Foundation for Research and Technology-Hellas (IACM-FORTH).

    Looking forward to welcoming you all to Kalamata in 2021.

    John S. Papadakis
