As part of nine campaigns on the DSSV Pressure Drop, full-ocean-depth CTD (conductivity, temperature and depth) sensors were deployed using lander systems. The landers included a baited camera setup and acoustic release mechanisms for recovery and were deployed for approximately 8 hours on the seafloor. The data presented here is only the downcast profiles due to hydrodynamic lander effects and is post-processed and corrected as recommended by Seabird (CTD manufacturers). The campaigns were carried out between 2019 and 2022. The geographical coverage is over the Indian Ocean, Southern Ocean and Western Pacific at locations over 6000m in depth. The data was collected to support the baited lander video footage to obtain abiotic conditions at the sites of the videos. This data is included within Kolbusz et al. 2023, please see the full paper for further details. The study underscores the importance of incorporating these adiabatic conditions for insights into ecological biodiversity, alongside the baseline conditions presented being indispensable for future oceanographic research across multiple disciplines.
