FS Polarstern PS111
Cruise summary report
| Cruise Info. | |
| Ship name (ship code) | FS Polarstern (06AQ) |
| Cruise identifier | PS111 |
| Cruise period | 2018-01-19 — 2018-03-14 |
| Status | Completed |
| Port of departure | Cape Town, South Africa |
| Port of return | Punta Arenas, Chile |
| Purpose | Research |
| Objectives | Autosub Long Range Deployments in the southern Weddell Sea. This project aimed to study the region near the front of Filchner-Ronne Ice Shelf using an Autonomous Underwater Vehicle (AUV) to measure water properties and currents along a series of transects linking ship-based observations to the north with sub-ice observations in the south. |
| Chief scientist | Adrian Jenkins (British Antarctic Survey), Michael Schröder (Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research) |
| Coordinating body | British Antarctic Survey (BAS) |

| Subsurface temperature and salinity measurements | Quantity: track kilometres = 203 Description: Along-track data collected by AUV operating between 0 and 950 m below the surface, mostly beneath permanent ice cover. Pressure, temperature and conductivity recorded by two CTD systems (Seabird SBE-52 and Idronaut OceanSeven 304), currents above and below the vehicle recorded by two RDI 300 kHz ADCPs, optical backscatter recorded by Wetlabs ECO-FLNTU fluorometer/scatterometer, and mircrostructure recorded by RSI MicroRider. |
| Transparency (eg transmissometer) | Quantity: track kilometres = 203 Description: Along-track data collected by AUV operating between 0 and 950 m below the surface, mostly beneath permanent ice cover. Pressure, temperature and conductivity recorded by two CTD systems (Seabird SBE-52 and Idronaut OceanSeven 304), currents above and below the vehicle recorded by two RDI 300 kHz ADCPs, optical backscatter recorded by Wetlabs ECO-FLNTU fluorometer/scatterometer, and mircrostructure recorded by RSI MicroRider. |
