Overview

In the Linked Earth context, a working group (WG) is a self-organized coalition of knowledgeable experts, whose activities are governed herewith. This page is dedicated to the discussion of data and metadata standards for MARPA (marine annually-resolved proxy archives, including corals, mollusks, and sclerosponges), and aims to formulate a set of recommendations for such a standard. Note that chronological aspects should be discussed within the Chronologies WG.

Members of 'MARPA Working Group'

Specific tasks

We recommend that discussions focus on the following techniques, and explore potential commonalities.

Definition of essential, recommended, and desired metadata in the context of paleoclimate data standards

For each chronology type, we recommend:

  • structuring discussions around what scientific questions one would want to ask of the data
  • listing essential, recommended, and desired information for:
    • the measurements themselves
    • any inference made from the measurements (e.g. calibration to temperature)
    • the underlying uncertainties, and what those numbers correspond to (e.g. 1-sigma or 2-sigma?)
  • provide an ideal data table for each type of observation, so the community knows what to report and how to report it.
  • provide separate recommendations for new and legacy datasets

Sub-groups

Corals

observations to describe:

  • stable isotopes
  • trace elements
  • radiocarbon

Sclerosponges

Mollusks

Coralline Algae

MARPA Standards : Template 1st draft

Below is a summarizing the metadata from the File:MARPA Template.xlsx. See the Discussion to comment on the template, fill out the table below, and vote on the polls.

See this page for the definition of essential, recommended, and desired metadata for the standards developed by LinkedEarth.

Physical Sample metadata - SESAR

Note: Although the new release of the LinkedEarth ontology will include a PhysicalSample category, there are no formal ways to describe the samples beyond their name, the possibility to enter an IGSN number or a lab ID number, a Collection Method, and where the sample is currently located.

Metadata for the PhysicalSample
Metadata Essential (E), Recommended (R), Desired (D) Comments
Sample Name
IGSN
Parent IGSN
Material According to SESAR metatada, categorizes the material that composes to the sample (e.g., water, granite, tissue). Proposed classification: Biology
Field Name In the LinkedEarth Ontology, this would be the SensorSpecies and SensorGenus
Classification e.g., Marobiology>coral
Sample description e.g., Scleractinian corals, core 236cm - 6 sections
Age (min/max) and associated units In the LinkedEarth framework, the minimum/maximum age is automatically calculated from the chronology information when a file is transformed into LiPD
Geological age
CollectionMethod
Size and associated units
Latitude
Longitude
Elevation start
Navigation Type
Location description e.g., lagoon
Locality e.g., Vanua Balavu
Locality description e.g, North of Susui village on east side of exposed reef
Country e.g., Fiji
State/Province
County
City/Township
Field program/Cruise e.g., Evohe 2004 Expedition
Collector/Chief Scientist e.g, Braddock K. Linsley
Collection date 4/11/04
Collection date precision day
Current archive Where the physical sample is currently curated. e.g., LDEO Core Repository
Current archive contact e.g., Braddock K. Linsley

Publication data

The proposed scheme is similar to the one proposed by LinkedEarth. See this page for more information

Timeseries Data

Matadata pertaining to time series data
Metadata Essential (E)/Recommended (R)/Desired (D) Comments
Raw data Raw measurements reported against depth in the archive
Monthly interpolated data measured variables (e.g., D18O, D13C, Sr/Ca) and/or inferred variables (e.g., Sea Surface Temperature) reported against the monthly age model

Note: Do not edit the polls (even for typos) once voting has started as it will reset the vote counts to zero. If a change needs to be made, make an annotation above the old poll (i.e., above the poll tags) and place the new poll below the first one.

Results of the poll run on Twitter from April 11th to 18th 2017
For MARPA archives, should the position where the measurements was taken on the archive (i.e. depth) be:

Measurement Metadata

Instrument Section

In the LinkedEarth ontology, this refers to the Instrument.

Metadata regarding the instrument
Metadata Essential (E)/ Recommended (R)/ Desired (D) Comments
Instrument Type We created an ontology for the various types of instruments. It's set as the category for the page.
Instrument Name e.g., Micromass Optima gas-source-triple-collector
Method Name of the method or paper published about it. In the LinkedEarth framework, the method is described at the variable rather than the instrument level. This allows for multiple methods used on the same instrument since the method is related to the measurements rather than the tools.
Notes Additional information
Institution Name of the Laboratory that ran the samples. In LinkedEarth, this is achieved through the property housedAt which links to a traditional wiki page. Information about the laboratory can be entered on this new page for general information
Creator In LinkedEarth, the contributors of the datasets are acknowledged of the datasets and should include the authors on the publication as well as anyone who has contributed to producing the data (e.g. lab managers and technicians not included in the publication).
