Abstract:
The MacArtney Triaxus extended version is a remotely operated towed vehicle (ROTV). It is towed behind the ship between 2 and 10 knots and can undulate in a saw tooth pattern between a few meters below the surface and 350m depth. The umbilical provides power and a fiber optic link to sensors that are mounted on the Triaxus (see SensorWeb). The different data streams require separate processing. Here we report the data from the Seabird 911+ dual pumped CTD system mounted on the Triaxus. The provided data are 0.5 second or 0.5 meter averages. The operations included profiling mode and constant depth mode. Depth data comes from the CTD's pressure sensor. Position data (latitude, longitude) comes from the ship's GPS system and is corrected for the length of the umbilical behind the ship. Standard Seabird Data processing (SBE Data Processing) were applied. A front in the open ocean region in the vicinity of the ice edge in Fram Strait was searched for with a ~100km long constant depth Triaxus transect on July 8. When a front had been found, it was surveyed in 3D by parallel UCTD sections and drifters were deployed. The front was followed until July 16 with the repeat of parallel UCTD and Triaxus sections. In total 17 sections were occupied with the Triaxus.
