Bathymetry

Page content (please note)
Please note, bathymetry data curation SOP'S in PANGAEA with respect to FAIR data principles (https://doi.org/10.1038/sdata.2016.18) are currently revised within the scope of of the DAM Underway research data project (https://www.allianz-meeresforschung.de/). This page and the information provided here is adressed to PANGAEA user and data submitters.

PANGAEA's Metaheader (https://wiki.pangaea.de/wiki/Metaheader) expliiatly for bathymetry data sets and other data curation requirement are explained on this page.

DAM Underway research data project background
text text text

Standardized Title
To ensure the reusability (R) and Interoperability (I) of data sets, metadata of similar data sets such as bathymetry data mostly gathered during specific research missions from research vessels or other researh platforms, should follow a common template and using common vocabulary. This is also including the title.

Therefore, the title of bathymetry data which are entrusted to PANGAEA shall follow a certain template “construction kit”. This “construction kit” was developed within the DAM efforts (Project Underway research data). It is including the feedback of several German scientist from different institutions, PANGAEA bathymetry data submitters & data management personal.

Key elements of each data set title are incorporated, such as data type, data level, device, platform type, platform, cruise (& area)

PANGAEA is encouraging data submitters to follow this template in order make the data as FAIR as possible (more information is provided as soon as possible. The latest “construction kit” - incorporating all feedback - will be presented to the community very soon.....).:

Standardized Abstract
text text text https://wiki.pangaea.de/wiki/Abstract

Standardized usage of Reference
Typically, processed data from one entire cruise are delivered to PANGAEA which are built on the “same” raw dataset also archived in PANGAEA. These datasets shall be linked as a Reference to each other. Currently, all bathymetry datasets already archived in PANGAEA are reviewed and checked. If a relationship is found, a linkage between both datasets is being created. More information can be found here https://wiki.pangaea.de/wiki/Reference

Standardized Coverage
text text text Automatcal entry in PANGAEA calulated from Events or PANGAEA Geocode (see below) https://wiki.pangaea.de/wiki/Metaheader

Standardized usage of Events
Bathymetry data sets contain so called PANGAEA Events (https://wiki.pangaea.de/wiki/Event). Different information is included here. Each campaign included an so called "underway" Event

The "underway" Event is named CruiseID_underway-number(undefined) e.g. M127_underway-1. The event shows the starting and end point (coordinates & datetime) of the first and last data record which is contained in the dataset. Also, the Methods/device used to this dataset is included for Event decription. Please note, that PANGAEA specific vocabulary is used here. Providing further detailed information using standard common vocabulary such as the NERC catalogue (https://www.bodc.ac.uk/resources/inventories/nerc_data_catalogue/) is currently being prepared (more information is provided as soon as possible.....).

If available, an additional link to the Sensor description hosted on https://sensor.awi.de is provided. The Event also links to the scientific Campaign and Basis (platform) containing further additional information. Please note if you browse with your mouse cursor on Campaign or Basis, a field will pop up (do not click), respectively. However, in addition occasionally you also click on these fields (a link is occasionally included here).

If the dataset is complied (dataset compilation) of many dataset (only possible for processed data), several "underway" events will be used.

Note, that the prefix of the Event name contains the official cruise ID (cruise label, e.g. https://www.pangaea.de/expeditions/bybasis/Meteor%20%281986%29), not the campaign name. In addition, the suffix number does not follow a specific rules, since this number is chronologically being created mostly already on bord, therefore the numbering can differ from cruise to cruise.

Standardized usage of Parameter (for raw data curation)
The usage of PANGAEA parameter (https://wiki.pangaea.de/wiki/Parameter) for bathymetry data sets depend if raw or processed data are being submitted.

Standard parameters for bathymetry raw data include also PANGAEA’s so called Geocodes (https://wiki.pangaea.de/wiki/Geocode), which are latitude, longitude & datetime. In addition, file format, file size and file content are standard important parameters, which are mandatory to keep the data georeferenced and described.

These metadata will be automatically attached while data curation process.

Other parameters will also be automatically be created and added (more information is provided as soon as possible.....).

Standardized usage of Parameter (for processed data curation)

Standardized usage of Data model extensions (for raw and processed data curation)
The usage of so-called data model extensions which are further attributes is currently developed. This is a new feature for PANGAEA in order to include more standardized metadata. This new feature shall insure further findabilty (F) and interoperability(I) of the data sets (more information is provided as soon as possible.....).

Standardized usage of Comment (dataset level, visiable on PANGAEA dataset page)
Bathymetry raw and processed data which are acquired on scientific vessels might contain erroneous depth values and/or data artifacts. These data shall never be used for navigational purposes involving safety at sea. For safty reasons, it is widly common to state this explicitly.

Therefore the comment These data should not be used for navigational purposes will be included as a comment on each bathymetry dataset in PANGAEA.

Please also check PANGAEA data policy https://wiki.pangaea.de/wiki/Data_policy (page currently under construction).

Bathymetry data for official nautical chart production must explicitly fulfil requirements of the International Hydrographic Organisation (IHO) https://iho.int/
