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.

Specific tasks

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

For each chronology 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?)
• 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, and for how to label measured and inferred variable (e.g. Mg/Ca is measured, temperature is inferred)

Sensor-specific considerations

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 community to rally around sub-groups start dedicated to data standards about the following sensors:

Foraminifera

Stable isotopes

Trace Metals

Alkenones

TEX86

Polls

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