HI Wolfram-

Yes, values for house standards and having those traced back to accepted standards (primary or secondary, along with the nominal values used) would be needed.  The 0.3 per mil shift in the secondary standards for organic C in 2006 comes to mind.

take care,

gerry

Hi Chad,

 

 

Very good point.

 

That being said, I am still wondering what the benefit would be of submitting “raw” data to any data base or to make acceptance of a manuscript contingent to prior data submission to a data base.

 

I also wonder how this would work in practice considering in the stable isotope world we have guidelines in places (issued by IUPAC / CIAAW) that state published delta value must be scale normalized using 2 scale anchors.  Despite these clear guidelines papers reporting such data  that are neither traceable nor comparable still get published even if rejected at the peer review stage on grounds of not having been scale normalized.

 

In the context of stable isotopes, my understanding of the term “raw” stable isotope data is stable isotope abundance data as measured, i.e. delta values that have not been yet properly scale normalized using 2 appropriately chosen scale anchors (and ideally at least one reference material serving as quality control).

 

To my mind a fundamental prerequisite on data for submission to any data base is for entries to have been generated in such a way to ensure traceability and, more importantly comparability (reproducibility).

 

 

Best,

 

Wolfram

If manuscript acceptance becomes contingent upon submission of raw data to repositories there also needs to be some sort of protection for data producers who might have further publications based on the data in the pipeline.  There are research groups out there who make a living publishing repository data, which can become a serious issue for folks with work in the pipeline.  Hence the common practice of restricting public release of theses and dissertations for 1-2 years after completion.

I think Hydrological Processes has such a publication type. Although I am not sure if all data published that way goes to a common repository

Just a thought,

Hi,

Great idea but don’t forget there’s already a tree-ring isotope database coordinated by NOAA. Alas, participation is rather low. See:

 

https://www1.ncdc.noaa.gov/pub/data/paleo/treering/isotope/

 

The secret is getting colleagues to submit data!

 

Best wishes,

Dear Brian

Great initiative. We’d be happy to contribute down-under from New Zealand. After being a participant for many years in inter-lab ring tests, and seeing the (sometimes) horrendous lab outliers, is there a way that data could be assigned a confidence factor (A+, B, C etc), depending on its originating laboratory?

 

Kind regards

Karyne

Hi all,

 

The last few years have seen a groundswell of support for the idea of a centralized repository for stable isotope data. I have talked about this at the last two IsoEcol meetings and there are several researchers on this list actively working towards this goal. Last year, Jon Paul, Seth Newsome and others brought a few of us who are interested in this kind of thing to New Mexico to try put some structure on what a repository for stable isotope data should look like. I’m pleased to say that one of the outcomes of that meeting was an opinion article which has just been published in PNAS (http://www.pnas.org/content/114/12/2997.full.pdf). There are many challenges to building a reliable and effective repository for stable isotope data but we hope that this paper at least serves as a ‘call to arms’ for the isotope community to achieve this goal. Anyone interested in contributing this this effort please keep in contact as there will hopefully be more developments on this front later in 2017.

 

All the best,

 

Brian
