On this page you will find information on the requirements for submitting, archiving and publishing Thermosalinograph (TSG) Underway Data, as well as examples of datasets.

Please note

SOPs for the curation and publication of Underway Data are currently being revised within the DAM Underway Research Data Project to ensure fulfilling the FAIR data principles with every Underway data publication.

This entire page is currently under construction and will be updated continuously

DAM Underway Research Data Project background

Underway Data from different devices

During DAM pilot phase, workflows for data curation, archiving and publication at PANGAEA are being revised. Besides Thermosalinograph (TSG), other types of processed Underway Data from different devices are in the scope of the project:

Furthermore, historical and recent Bathymetry data and corresponding workflows are under revision in the framework of DAM.

Example of an Underway TSG Data Publication

Schoening, Timm; Schlundt, Michael (2021): Continuous thermosalinograph oceanography along Maria S. Merian cruise MSM96. PANGAEA, https://doi.org/10.1594/PANGAEA.927951

Standardized Meta-Information of Underway Data

The following information needs to be included in any Underway Data submission at PANGAEA. To start a data submission at PANGAEA, go to https://www.pangaea.de/submit/ . Further information on the ticket system used for communication and documentation during the processing of the data submission can be found in this wiki.

Abstract/Describe your Data #Abstract; if the #Data Processing Report or the #Raw Data are already archived, the links may be placed here Underway temperature and salinity data was collected along the cruise track with two autonomous measurement systems. Usually, the systems are changed after 12 hours. While temperature is taken at the water inlet in about 6.5 m depth, salinity is estimated within the interior measurement container from conductivity and interior temperature.

Salinities are calibrated against discrete reference data obtained from water samples along the cruise track. This calibration is performed independently for both measurement containers. Eventually one time series is estimated for temperature and salinity.

License The license specifies how the record can be used and modified after publication and how it must be cited by re-users. The use of license CC-BY 4.0 is strongly recommended by PANGAEA and DAM, ensuring the re-usability of the Underway Data and the credit for the author(s) CC-BY: Creative Commons Attribution 4.0 International (default)

List of Authors

! Under Construction !

Usually, the list of authors of Underway Data contains the scientist responsible for the sampling device and the chief scientist. However, a final regulation on how to proceed with the list of authors in all Underway Data sets in the same way is still pending. The same goes for the PI, the contact person responsible for the data.

Dataset Title

The title of the data publication should be generalized and is defined by the specific [ship], [cruise] and [device] (see #PANGAEA Data Submission Form Example).

Abstract

For Underway Data, a generalized Abstract per device may be created that will be adapted to each dataset regarding [ship], [cruise] and certain peculiarities. For more information on what needs to be included in a PANGAEA data publication abstract see this page.

References

Several references may be of importance for Underway Data.

Cruise Report

The Cruise Report is usually already archived at the Technische Informationsbibliothek and will be linked to the dataset by a data curator (see this example).

Data Processing Report

The Data Processing Report contains information on processing and quality control procedures. It enables to reproduce the processed data from raw data. The preferred format for submission is pdf.

Example: Schlundt, Michael; Wölfl, Anne-Cathrin (2020): Continuous thermosalinograph oceanography along Maria S. Merian cruise MSM 88/2 - Data Processing Report. GEOMAR - Helmholtz Centre for Ocean Research Kiel, https://store.pangaea.de/Publications/Woelfl-Schlundt_2020/DAM_DataProcessingReport_MSM88_2.pdf

Currently, the Data Processing Reports are being archived at PANGAEA (except for reports for data obtained during Polarstern and Heincke cruises); A long-term solution will include the assignment of a doi for each Data Processing Report.

Raw Data

If possible, the raw data should be linked to the processed dataset. This link may lead to an external source, but it may also be an PANGAEA-internal link.

Further References

These may, for example, include Salinity samples as .txt files, netcdf files, etc. They will be stored on one of PANGAEA's servers and can be accessed via a link in the reference section of the data publication.

Further information

Cruise Label

The [Cruise] Label given should always include [ship]number/leg (e.g.: MSM88/2).

Event label(s)

The Event Label(s) should be part of each data submission. Event labels equal the station labels and provide meta-information for the data. The Underway Event Label is being created onboard and should always be used when referring to Underway Data (current exception: CTD Data - several events needed). The format of Event Labels format consists of the cruise label and the station ending: [ship]number/leg_station (e.g.: MSM88/2_0_Underway-2).

Device /Sensor

Information on the device used for measuring should also be provided, so it can be linked to the measured parameters.

Keywords/Project

Use "DAM:Underway Research Project" as project and technical keyword "DAMUnderwayReserach".

Data Table

File name

A generalized file name should be used per device (see #PANGAEA Data Submission Form Example)

File Formats

Possible file formats include .txt, .tab, .csv, .xlsx . The encoding is preferably UTF-8.

Layout

Please do not include any header except column names. The decimal separator should be "." and the number of decimals should always reflect the measurement precision. Numbers, which are not available, are displayed as blanks in PANGAEA. They should be included as blanks, "NaN", "NA" or event "999.999" in the data table.

Parameters of the data table

 ! Under construction - parameters may still be changed added for future Underway Data Publications !

This table gives an overview of how the parameter names and specifications will appear on the web and in the download file of the data. If possible, these names should be included in the submission data table. Also the format and unit of data should be submitted as displayed here. The methods, as specified in the submitted meta-information, will be included in the data publication by the data editor.
