In the coming years, exploration and mapping of the deep sea will be a priority for ARNET - Aquatic Research NETwork. In this context, this network has the support of Rebikoff-Niggeler Foundation, a non-for-profit organization for marine research. The Foundation’s goal is to facilitate research and in-situ observation and documentation of deep-sea environments and make film work for ocean documentaries. They work with their manned research submersible LULA1000, able to operate depths between 50 and 1000 metres, the only one active in Portugal.
