11th European Wave and Tidal Energy Conference (EWTEC 2015)

The 11th European Wave and Tidal Energy Conference was held in Nantes, France from September 6-11 2015 and was hosted by École Centrale de Nantes. Launched in 1993, EWTEC has become a well-established marine renewable energy conference that is widely respected for their commitment to maintain high standards in the quality of academic and industrial contributions to their proceedings. With a primary focus on technology development and engineering, EWTEC provides a forum for researchers, industry, and other stakeholders to interact, present the latest knowledge, and discuss new ideas and issues pertinent to wave and tidal energy extraction.

Annex IV and OES partnered with the 11th European Wave and Tidal Energy Conference to host an environmental track. The new environmental track added a total of six new environmental sessions to the conference (as opposed to one in 2013) that were spread out over the course of four days. The addition of this new track was able to attract many environmental researchers, stakeholder, and new faces to the EWTEC conference. More information on EWTEC 2015 can be found on their website. A Tethys Story has also been written on EWTEC 2015, which can be found here.

The following is a list of each EWTEC 2015 environmental session, including the title of each paper and authors.
