Bio-optical Sensors Underway Data

On this page you will find information on the requirements for submitting, archiving and publishing Bio-optical Sensors Underway Data, as well as examples of datasets.

Please note
Standard operating procedures (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. Therefore, this page will be updated accordingly.

Underway Data from different devices
During DAM pilot phase, workflows for data curation, archiving and publication at PANGAEA are being revised. Besides Bio-optical Sensors, other types of processed Underway Data from different devices are in the scope of the project:
 * ADCP Underway Data
 * Ferrybox Underway Data
 * CTD Underway Data
 * TSG Underway Data

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

Example of a Bio-optical Sensors Underway Data
Example of data set prior to DAM Underway project: https://doi.pangaea.de/10.1594/PANGAEA.912014 (Chlorophyll, tot = Chlorophyll a)

Example of data set belonging to DAM Underway project, which is under revision: https://doi.pangaea.de/10.1594/PANGAEA.942197

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.

Cruise Label
The [Cruise] Label given should always include [ship]number/leg (e.g.: MSM88/1).

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.: SO248_8-7).

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

File name
A generalized file name should be used per device (see )

File Formats
Possible file formats include .txt, .tab, .csv,. 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
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.

Note: If Quality Flags are used, the flagging code needs to be explained and will be archived in the parameter comment. Turbidity parameter should be aligned with Ferrybox turbidity. Depth, water equals suction height, water supply (different for different vessels), needs to be aligned with TSG depth, water.
