    Physical Oceanography measured with CTD on Triaxus topAWI (towed ocean profiler of the AWI) during MERIAN cruise MSM93 (2022)

    Publication Date: 2024-04-20
    Description: 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.

    Raw data from Triaxus topAWI (towed ocean profiler of the AWI) during MERIAN cruise MSM93 (2022)

    Description: 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 data collected by the sensors were recorded on separate computers, one computer per sensor (including the flight information from the Triaxus itself). Thus, there are 7 separate data streams saved in separate folders plus a folder with metadata information about the different dives. During long Triaxus operations, new data files would be started approximately every 4 hours, because some of the employed software programs do not allow for backing up of the files while they are still being written to. 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.

The attached archive contains raw data files of one Seabird SBE37 microcat (nominal depth: 345m; sampling interval 20 min) and one RDI Quartermaster ADCP (nominal depth: 345m; sampling interval 1h). Although the mooring was recovered in July 2020, data is only available until July 2019 due to instrument power failures. The records show also evidence that the mooring was moved at the end of November 2018, most likely by a bottom trawler. Auxiliary information such as sensor calibration sheets, mooring diagrams and schedule files are also provided, if applicable.

The attached archive contains raw data files of three Seabird SBE37 microcats (nominal depths: 46m, 247m, 731m; sampling interval 20 min), one RDI 600kHz ADCP (nominal depth: 34m; sampling interval 30min), one RDI Longranger ADCP (nominal depth: 403m; sampling interval 1h) and one AADI RCM11 current meter (nominal depth: 730m; sampling interval 2h). The 600kHz ADCP wasn't aligned correctly in the water column due to issues with the attached flotations. Therefore, the data is likely not usable. The mooring also included one ASL Acoustic Zooplankton Fish Profiler (nominal depth: 135m; data archived elsewhere) and one Develogic Sonovault (nominal depth: 790m; data also archived elsewhere). Auxiliary information such as sensor calibration sheets, mooring diagrams and schedule files are also provided, if applicable.

    Raw data from UCTD (Underway CTD) during MERIAN cruise MSM93 (2021)
    PANGAEA
    Details
    Publication Date: 2024-04-20
    Description: The Teledyne Underway CTD was operated in tow-yo mode: the winch brake is disengaged and the probe is in approximate free-fall at 4m/s to 1m/s vertical speed collecting data for a cast. Then the brake is engaged and the probe is hauled in until it is within 10m horizontal behind the vessel at the sea surface. The winch is then disengaged and the next cast starts. A straight section is collected with the same probe in the water. At the end of the section, the probe is recovered. The data is recorded internally on the probe and only read out once the probe is back on deck. 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. During one UCTD section, an operator error resulted in the fact that the probe appeared to have been started while in fact it had not been started before deployment. In total 21 sections were occupied excluding the section where no data was recorded (station MSM93_62-1).

A straight section is collected with the same probe in the water. At the end of the section, the probe is recovered. The data is recorded internally on the probe and only read out once the probe is back on deck. Here we provide 1 m vertically averaged data from the downcasts. The processing follows Ullman and Hebert: “Processing of Underway CTD Data”, Journal of Atmospheric and Oceanic Technology (2014), https://doi.org/10.1175/JTECH-D-13-00200.1. 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.
