title: Shipboard ADCP current measurements (75 kHz) during RV MARIA S. MERIAN cruise MSM138

description: Current velocities of the upper water column along the cruise track of R/V Maria S. Merian cruise MSM138 were collected by a vessel-mounted 75 kHz RDI Ocean Surveyor ADCP. The ADCP transducer was located at 6.0 m below the water line. The instrument was operated in narrowband mode (WM10) with a bin size of 8.00 m, a blanking distance of 8.00 m, and a total of 100 bins, covering the depth range between 22.0 m and 814.0 m. Beam velocities as recorded by the data acquistion software VmDAS were transformed to ship coordinates and after merging with the attitude data from the ship's Motion Reference Unit to geographic coordinates. The Python toolbox OSADCP (version 2.2.0) was used for data post-processing. Acoustic Interferences were identified based on outliers in the ADCP echo intensity data. Echo intensity data were cleaned accordingly and affected velocity cells were flagged to be removed prior ensemble-averaging. The ship's velocity was calculated from position fixes obtained by the Global Navigation Satellite System (GNSS), taking into account lever arms of ADCP transducer and GNSS antenna. Accuracy of the derived water velocities mainly depends on the quality of the position fixes and the ship's heading data. Further errors stem from a misalignment of the transducer with the ship's centerline. Data processing included water track calibration of the misalignment angle (-47.3235° +/- 0.5496°) and scale factor (1.0025 +/- 0.0100) of the measured velocities. The velocity data were averaged in time using an average interval of 60 s. Depth cells with ensemble-averaged percent-good values below 25% are marked as 'bad data'. Furthermore, the time series of cell 1 to 2 are flagged as 'potentially correctable bad data' because of velocities biases most likely caused by transducer ringing.

title: Multibeam bathymetry raw data (Kongsberg EM 122 entire dataset) of RV METEOR during cruise M151

description: Raw multibeam bathymetry data were collected using the ship's own Kongsberg EM122 multibeam echosounder during the RV METEOR cruise M151 (ATHENA). The cruise took place between 2018-10-06 and 2018-10-31 (Ponta Delgada, Portugal – Funchal, Portugal). The research was conducted along the slopes of the Azores Islands, of Atlantis Seamount and of Great Meteor Seamount (including the western Little Meteor Seamount). Detailed bathymetric mapping of the slope and plateau areas was conducted using the deep-water EM122 and the shallow-water EM710, along with sub-bottom profiling, to provide information for subsequent ROV dives and sampling. Additionally, sound velocity profiles (SVP) were collected using CTD and expendable sound velocity probes. The data are archived at the Federal Maritime and Hydrographic Agency of Germany (Bundesamt für Seeschifffahrt und Hydrographie, BSH) and provided to PANGAEA database for data curation and publication. Data are unprocessed and therefore contain incorrect depth measurements (artifacts). Data can be processed e.g. with the open source software package MB-System (Caress, D. W., and D. N. Chayes, MB-System: Mapping the Seafloor, http://www.mbari.org/products/research-software/mb-system/, 2022).

title: Continuous thermosalinograph oceanography along RV METEOR cruise track M209

description: Underway temperature and salinity data was collected along the cruise track with two autonomous thermosalinograph (TSG) systems, each consisting of a SBE21 TSG together with a SBE38 Thermometer. Both systems worked independent from each other throughout the cruise. While temperature is taken at the water inlet in about 5 m depth, salinity is estimated within the interior TSG from conductivity and interior temperature. No correction against independent data was performed for temperature. Salinity was calibrated against independent water samples. Finally, TSG2 was chosen for publication. For details to all processing steps see Data Processing Report.
description: Salinity was calibrated independently against water samples from 5 m depth (tim is the time in days since Expocode of this cruise (06M320250321), i.e. since 2025-03-21T00:00:00). Value added to salinity data TSG1 = 0.0010435*tim-0.040676. Value added to salinity data TSG2 = 0.0001678*tim+0.029049.

title: Continuous thermosalinograph oceanography along RV SONNE cruise track SO312

description: Underway temperature and salinity data was collected along the cruise track with two autonomous measurement systems, called self-cleaning monitoring boxes (SMBs). Usually, the SMBs are changed after a predefined period, while on this cruise mostly SMB_B was used. While temperature is taken at the water inlet in about 4 m depth, salinity is estimated within the SMB from conductivity and interior temperature. No temperature and salinity calibration was performed. For details to all processing steps see Data Processing Report.

title: LULC-1m: High-resolution land use/land cover data of 33 major Chinese cities based on remote sensing imagery
title: LULC-1m：基于遥感影像的中国33个主要城市的高分辨率土地利用与土地覆被数据

description: With the rapid advancement of urbanization, detailed land use/land cover data are of great significance for urban management, ecological assessment, and sustainable development research. This paper proposes and constructs a high-precision LULC dataset—LULC-1m—covering 33 major Chinese cities with a spatial resolution of 1 meter. Based on multi-source high-resolution remote sensing imagery, this dataset utilizes an automated processing workflow and deep learning semantic segmentation algorithms to achieve fine-grained identification of seven typical LULC types on the urban surface (overall accuracy reaching 88.90%). This study systematically designed the data processing workflow, semantic consistency control, and cross-regional generalization capabilities, significantly improving the consistency, accuracy, and applicability of the data. LULC-1m provides crucial fundamental data support for land spatial monitoring, carbon emission accounting, and environmental modeling at the scale of Chinese urban agglomerations, and has broad prospects for scientific research and policy applications.

title: Continuous thermosalinograph oceanography along RV HEINCKE cruise track HE614

description: Raw data acquired by a thermosalinograph (SBE21, SeaBird GmbH) on board RV HEINCKE were processed to receive a calibrated and validated data set of seawater temperature and salinity. Data were downloaded from DAVIS SHIP data base (https://dship.awi.de) with a resolution of 1 sec. The SBE21 was equipped with an additional external temperature sensor (SBE38, Sea-Bird GmbH). Raw data are converted to temperature and conductivity values using the calibration coefficients from the calibration before deployment. However, data can only be finally processed after replacement and renewed calibration because correction values for the sensor drift can only be obtained by the post cruise calibration. The thermosalinograph on board RV HEINCKE is exchanged about once a year and calibration procedures are conducted after every exchange. Salinity was calculated according to the instructions from the Practical Salinity Scale PSS-78 using the obtained internal temperature and conductivity data. Processed data are provided as 1min means of salinity and seawater temperature aligned with position data taken from master track of the respective cruise. Quality flags are appended according to the SeaDataNet Data Quality Control Procedures (version from May 2010).
