== Overview ==
In the Linked Earth context, a [[:Category:Working_Group|working group]] (WG) is a self-organized coalition of knowledgeable experts, whose activities are governed [[:Category:Working_Group|herewith]]. This page is dedicated to the discussion of data and metadata standards for '''marine sedimentary archives''' (see [[:Category:MarineSediment | 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|Julie Richey (USGS)]]

__MEMBERS__

== 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 =====
<poll>
Should the cleaning methodology be considered:
Essential Metadata
Recommended Metadata
Desired Metadata
</poll>

===Organic Geochemistry===

====Alkenones====

====GDGTs====

<poll>
Should raw peak areas (as opposed to just TEX86 index) be:
Essential Metadata
Recommended Metadata
Desired Metadata
</poll>

====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''':
<poll>
Do you endorse X, Y Z as the three (and only three) essential metadata fields for datasets derived from marine sediments?
Yes
No
Maybe so
</poll>

For '''LEGACY DATASETS''':
<poll>
Do you endorse A, B C as the three (and only three) essential metadata fields for datasets derived from marine sediments?
Yes
No
Maybe so
</poll>

This is an example poll. To vote on what should be considered Legacy, see this [[:Category:Working Group | page]].

<poll>
For marine sedimentary archives, how old does a dataset have to be in order to qualify as 'legacy'?
Pre-bomb
Pre-historic
Pre-internet
Published prior to June 23 2016
</poll>

OK, I hope I'm doing this right. Somehow I find the wiki thing not very intuitive and I'm too lazy to find out how it really works...

Here's what I use for my own project; I don't distinguish between stable isotopes, Mg/Ca and trace elements when it comes to metadata. Since I'm working with legacy datasets there are only a few things that I consider essential (indicated with (E)), but I think we should push to make the remaining metadata fields at least recommended: 

Parameter (E) 
Parameter.type (E): measured or inferred 
Parameter.unit (E) 
Parameter.analytical.error: based on repeat measurement of standard, 1SD 
Parameter.reproducibility: based on repeat measurement of sample, 1SD 
Instrument 
Laboratory 
Species (E): in case of foraminifera 
Nshells.measured: number of shells used 
Size.fraction: size fraction of foraminifera shells 
Notes 
Habitat.Season: from paper 
Habitat.Depth: from paper. add epifaunal, infaunal for benthics 
Equilibrium.offset: from paper 
Calibration.eq: for inferred parameters 
Calibration.uncertainty 
Calibration.DOI 
Publication.DOI: publication(s) where data were reported 
Data.source (E): to allow tracing of legacy data, either DOI, link or ... 

For trace elements cleaning method would be a good one to include.
