Jegen, Anna; Lange, Dietrich; Kopp, Heidrun: Long-term temperature, pressure and sound speed data from seafloor stations clustered in three networks crossing the northern Chilean subduction trench (December 2015 - November 2018) [dataset].

Abstract:
In-situ measurements of pressure (kPa), high-resolution temperature data (°C) and sound speed (m/s) were acquired by a total of 23 stations. The stations were deployed on the continental slope and outer rise from late November to early December 2015 (Kopp et al., 2016). The stations were serviced with RV Langseth (Tréhu et al., 2016) and with OVP Odger in June 2018 and the data was uploaded from the seafloor. The final deinstallation of the stations was done with an ROV during SO288 (Kopp et al., 2022). Stations were deployed in three networks, one network is located on the mid-slope (Area 1, 8 stations), another on the lower slope (Area 3, 10 stations), and a third network on the Outer rise (Area 2, 5 stations).
