Marta Plaza from the BISITE group stayed in the H2O ROBOTICS company located in Zagreb, Croatia, to carry out research for the TECTONIC project. H2O ROBOTICS is part of the project consortium due to its extensive experience in autonomous robotics and other underwater technologies for marine research. Marta Plaza, instead, is a project manager and researcher at the BISITE Group and a Ph.D. student at the University of Salamanca. As part of the TECTONIC project, she is currently developing an intelligent platform for underwater cultural heritage management, so she stayed in the company H2O ROBOTICS for two months. There, she analyzed the key parameters and factors involved in the deterioration of underwater cultural heritage.
