A marine sediment core

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 marine sedimentary archives (see this page for a definition of Marine Sediment Archive), and aims to formulate a set of recommendations for such a standard.

Members

The group currently has one coordinator, Julie Richey (USGS)

Specific tasks

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

For each observation type, we recommend:

  • structuring discussions around what scientific questions one would want to ask of the data
  • listing essential, recommended, and optional 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?)
  • providing an ideal data table, so the community knows what to report and how to report it.
  • providing separate recommendations for new and legacy datasets, and for how to label measured and inferred variable (e.g. Mg/Ca is measured, temperature is inferred)
  • thinking about how the rest of the paleoscience community, or other (non)scientists may make use of the data you describe.

Marine sediments are a very ubiquitous archive on which many types of observations are made, and involving thousands of people around the world. It seems wise for this WG to rally around sub-groups start dedicated to data standards about the following sensors/observation types:

Geochemical Data

Foraminiferal Geochemistry

Stable isotopes

Trace Metals

Mg/Ca

In the following table, enter the metadata that you'd wish every member of the Mg/Ca community would enter to make their data reproducible. To add more lines, follow this guide. For a definition of Essential (E)/ Recommended (R)/ Desired (D), see this page.

Table 1: Essential/Recommended/Desired Metadata for foraminiferal Mg/Ca

To gather rapid feedback on whether the proposed metadata should be essential, recommended or optional, answer the polls below:

Should the location information (especially in relation to water depth) be:
You are not entitled to vote.
You are not entitled to view results of this poll.
There was one vote since the poll was created on 20:34, 17 February 2017.

Should the sensor genus/species information be:

Should the cleaning methodology be considered:

Organic Geochemistry

Alkenones

GDGTs

Should raw peak areas (as opposed to just TEX86 index) be:
You are not entitled to vote.
You are not entitled to view results of this poll.
There were 4 votes since the poll was created on 19:20, 21 November 2016.
poll-id 661DF66A537B28E6EBFFACB0E845D584

Compound specific isotopes

Physical Data

Grain Size

Micropaleontological Data

  • Report raw counts if available. And if not, at least
  • Minimum number of specimens counted
  • Size fraction

If the data were used to infer temperature or sea ice concentration, then the method (MAT, WA-PLS, etc) and the training set should be mentioned/required metadata.

Polls

Here are three example polls that the group might want to consider:

For NEW DATASETS:

Do you endorse X, Y Z as the three (and only three) essential metadata fields for datasets derived from marine sediments?
You are not entitled to vote.
You are not entitled to view results of this poll.
There was one vote since the poll was created on 17:12, 7 September 2016.
poll-id 1B22960F1414C1EA80123B9E4005065F

For LEGACY DATASETS:

Do you endorse A, B C as the three (and only three) essential metadata fields for datasets derived from marine sediments?
You are not entitled to vote.
You are not entitled to view results of this poll.
There were 0 votes since the poll was created on 17:12, 7 September 2016.
poll-id 4320E43008C4B751C1561253CEE455F2

This is an example poll. To vote on what should be considered Legacy, see this page.

For marine sedimentary archives, how old does a dataset have to be in order to qualify as 'legacy'?
