Raw water column data were collected aboard RV SONNE during cruise SO292 using a Kongsberg EM 710 multibeam echosounder. The expedition took place during 15.05.2022 – 21.06.2022 from Nouméa (New Caledonia) - Nouméa (New Caledonia) in the central Pacific Ocean. The main objective of SO292 was to analyse the sedimentology, the stratigraphy and the oceanography of the isolated carbonate platforms of the Queensland Plateau (NE Australia) within the ICECARB project. Data were recorded within the Australian EEZ. Sound velocity profiles (SVP) were applied on the data for calibration. Please see environmental data and the cruise report for details. The data are unprocessed and can therefore contain incorrect depth measurements (artifacts) if not further processed. Note that refraction errors may occur when no proper SVP is applied. Data provision is part of the DAM Underway Project and published according to the FAIR principles.

The seismic data were collected on the Queensland Plateau during RV SONNE expedition SO292 in spring 2022 (Betzler et al., 2022). The seismic signals were generated by two simultaneously released GI-Gun (true GI-Modus; primary volume of 45 in3) and a Mini-GI source (true GI-Modus; primary volume of 15 in3), towed 41 m behind the ship's stern and in a water depth of ca. 2.5 m. Sources were released by a GPS-controlled PC every 18.75 m at 160 bar. To synchronize seismic sources and trigger the recording system, a SureShot trigger system was used. This system allowed to display and adjust the source signatures measured by hydrophones attached to the seismic sources for each shot and therefore enabled an online quality control during the watchkeeping. The streamer was a Hydroscience Technologies SeaMUX 144-channel system with an active length of 600 m and symmetric group interval. The recording length was set to 4 s, the sample interval was 1 ms. Raw data were stored in SEG-Y format.All seismic profiles were processed on board with the 2021 VISTA® desktop seismic data processing software by Schlumberger. The main processing steps were Bandpass filtering (18/25 – 350/450 Hz), velocity analysis (every 25-500 CMP), spherical divergence correction, NMO-correction and stack, FD migration, topmute, data enhancement (white noise removal, fx deco), scaling. Processed data contained in this dataset are stored as SEG-Y. UTM coordinates (UTM zone 55) are stored at trace header position 181 (4-byte) and 185 (4-byte).

During cruise SO292 of the RV SONNE from 15 May to 21 June 2022, oceanographic surveys were conducted on an isolated carbonate platform of the Queensland Plateau (northeast Australia). Two so-called Yoyo-CTD deployments were carried out here. The data sets obtained include directly measured parameters such as water temperature, conductivity, oxygen, fluorescence and turbidity as well as derived parameters such as potential temperature, density, salinity and sound velocity. The composition of the water masses and the oceanographic conditions contribute to the understanding of the sedimentation processes on an isolated plateau and help to understand the development of drift deposits. The CTD data also support the interpretation of the hydroacoustic and sedimentological investigations during the research campaign. The long-term CTD deployments of more than one day also make it possible to better understand internal water movements and to observe changes in the water column due to tides and internal waves.

During cruise SO292 of the RV SONNE from May 15 to June 21, 2022, oceanographic investigations were carried out on an isolated carbonate platform of the Queensland Plateau (northeast Australia). A total of nine regular CTD casts were conducted with the ship's own CTD rosette. The data set obtained includes directly measured parameters such as water temperature, conductivity, oxygen, fluorescence and turbidity as well as derived variables such as potential temperature, density, salinity and sound velocity.

Atlas Parasound P70 (mk2) echosounder data was recorded during RV SONNE cruise SO292 (ICECARB, 15.05.2022 to 21.06.2022, Queensland Plateau, NE Australia). Data were acquired in parallel to multi-channel seismic surveys and as stand-alone surveys, with cruising speeds of 5.5 and 7 to 8 kn over ground, respectively. The desired primary high frequency (PHF) of the system was set to 18 kHz, the secondary low frequency (SLF) to 4 kHz. The PS70 was operated in single pulse mode with a transducer voltage of 100 V, and a transceiver amplification of 30 to 40 dB. Sound-velocity profiles (SVP) and salinity profiles of the water column were obtained from CTD measurements when available, and by using XSV-02 probes (Lockheed Martin, Sippican Inc.) for underway measurements. Data were stored in the PARASOUND-native format PS3 as well as in the PARASOUND raw-data format ASD. Whereas ASD data contain the complete acquisition range (0 to 2000 m of water depth), data stored in PS3 only record a specific time window (typical 200 ms in length) starting from just above the sea floor and automatically tracked using the mk2 capabilities. Typical sub-seafloor penetration during SO292 was around 10 m on the top of the carbonate banks (water depth around 50-60 m), almost 0 m at steep- and/or lithified parts of the platform slopes, and 80 to >140 m in the drift sediments surrounding the platforms.

Raw water column data were collected aboard RV SONNE during cruise SO292 using a Kongsberg EM 122 multibeam echosounder. The expedition took place during 15.05.2022 – 21.06.2022 from Nouméa (New Caledonia) - Nouméa (New Caledonia) in the central Pacific Ocean. The main objective of SO292 was to analyse the sedimentology, the stratigraphy and the oceanography of the isolated carbonate platforms of the Queensland Plateau (NE Australia) within the ICECARB project. Data were recorded within the Australian EEZ. Sound velocity profiles (SVP) were applied on the data for calibration. Please see environmental data and the cruise report for details. The data are unprocessed and can therefore contain incorrect depth measurements (artifacts) if not further processed. Note that refraction errors may occur when no proper SVP is applied. Data provision is part of the DAM Underway Project and published according to the FAIR principles.
