The deep ocean trenches, or hadal zone, are amongst the most poorly studied regions on the planet. This is particularly true of the hadal water column, as most of the hadal research to date focused on the geology, biology, and ecology of the seafloor. Existing observations suggest that rather than being quiescent and isolated from the ocean above, the hadal zone is ventilated on surprisingly short timescales, with some radionuclide studies suggesting residence times of less than five years. Genetic studies have identified the same species in neighbouring, yet bathymetrically isolated trenches. With funding from the W. M. Keck Foundation we designed and fabricated the multidisciplinary 11 km-depth rated Hadal Water Column Profiler. On 8-9 December 2021 we successfully tested the profiler from the R/V Kilo Moana.
