On October 9, 2024, the third online meeting of the ESPA Thalasso working group took place led by Marlies Sobczak, a board member of the ESPA. Experts from different countries exchange information and new research findings in this working group. In 2023, Marlies Sobczak created a working group to promote the concept and marketing around Thalasso and the first online meeting took place in April 2024. The European list of participants is growing steadily and journalist Laura Powell from the US acts as an intermediary to North America for the ESPA.

In 2002, the kick-off of Thalasso as a therapeutic wellness treatment method took place in the German seaside resort of Norderney. Willem Loth (director Staatsbad Norderney, Germany), Dr. Raschke (Head of Research Dept. Staatsbad Norderney (Germany) and Lourdes Mourelle (member of the FA2 research group / Applied Physics department of the University of Vigo, Spain) were from the first hours intensively involved in the promotion of Thalasso as a growing – but still unknown – market.
