Some of the tools used for deep sea exploration are:

Sonars, which are devices that emit sound waves and measure their reflections to map the ocean floor and detect objects and features.
Profilers, which are instruments that measure the vertical distribution of physical, chemical, or biological properties of the water column, such as temperature, salinity, oxygen, or plankton.
Cameras, which are devices that capture images or videos of the deep sea environment and its organisms, either attached to submersibles or mounted on frames or tripods.
Submersibles, which are vehicles that can dive into the deep sea and carry humans or instruments, such as human-occupied vehicles (HOVs), remotely operated vehicles (ROVs), or autonomous underwater vehicles (AUVs).
Drifters, which are floating devices that move with the ocean currents and transmit data on their location and other parameters via satellite.
Environmental DNA (eDNA), which is the genetic material shed by organisms in the water column that can be collected and analyzed to identify the presence and diversity of marine life.
Magnetometers, which are passive instruments that measure changes in the Earth’s magnetic field and can be used to locate underwater archaeological sites or geological features.
Geographic Information System (GIS), which is a computer-based framework for organizing and analyzing data related to positions on Earth’s surface and can be used to create maps and models of the deep sea.
Photogrammetry, which is a method of approximating a three dimensional structure using two dimensional images and can be used to record underwater archaeological sites or seafloor features.
Satellites, which are devices that orbit the Earth and detect and observe different characteristics and features of the atmosphere, land, and ocean, such as temperature, color, chlorophyll, or sea level.
