Thetis in Greek mythology is a sea nymph or a goddess of water, one of the 50 Nereids, daughters of the ancient sea god Nereus.

The submarine carries two people, the pilot and a scientist, who sit in a... bubble and can reach a maximum dive depth of up to 610 meters below the surface of the sea.

The submarine's dives are conducted at HCMR's oceanographic vessel "AEGEO" (Aegean Sea), which features all necessary infrastructure for dive support.
Thetis, with a total weight of approx. 5 tons, is equipped with modern navigation technology, communication with the surface and seabed survey.

Two robotic arms, sensors, samplers, projectors and cameras compose the equipment which allow the submersible to perform a wide range of operations on the seabed.

The maximum dive time can reach 7-8 hours, depending on the work and energy consumption.
From 2000 Thetis has been used in dozens of research trips and with different research subjects: Underwater archeology, ancient and modern wrecks, underwater volcanoes (Santorini, Columbo, Nisyros, Milos and elsewhere), the seabed ecosystems (deep corals) and many more.
"I work with HCMR since 2003, my main task is operating Thetis", says submarine Commander Kostas Katsaros and adds: "Diving with Thetis is always a unique experience and each dive has its own beauty".
