Apr 2015. Datasets published with DOIs in the EarthChem Library can now be accessed from related articles in ScienceDirect. EarthChem banners are shown on ScienceDirect when EarthChem has data for the article. Previously, sample-based geochemical data from the EarthChem Portal were displayed. Now, a summary and link to EarthChem Library dataset profiles are also linked.
If you are an author contributing to the EarthChem Library, make sure to specify the related dataset DOI in your Elsevier manuscript.
Example article: Pb and Hf isotope variations along the Southeast Indian Ridge and the dynamic distribution of MORB source domains in the upper mantle, Hanan et al., 2013.

Mar 2015. Guided by a group of Aleutian Arc investigators, high-profile geochemical analytical data sets were identified to aid the research community working in this area in data synthesis and interpretation. Over 9,000 geochemical data points from 50 references spanning the years 1961-2010 have been added to PetDB, including 2,400 mineral and over 1,000 melt inclusion analyses. Figure 1 shows the location of samples for which there are data available in PetDB. Figure 2, which depicts 144Nd/143Nd values across the arc, provides an example of the data probing that is now possible because of the recent data additions. To access the data, search PetDB by “Feature Name>Volcanic Arc>Aleutian/Kamchatka/Kuril-Kamchatka.”

Feb 2015. There will be a meeting prior to the LPSC (Lunar and Planetary Science Conference) on the archiving of lunar (and other planetary sample) data, particularly on geochemical data (e.g., bulk compositions, microprobe mineral analyses, isotopic data, etc.). More details about the meeting are below.
...I think this is a very worthwhile project; having a searchable database encompassing the previous 45 years of Apollo sample data would be an invaluable resource to the science community. As an example of the type of data product that would be in the database, please see the following link. www.earthchem.org/featured/delano
As food will be provided at the meeting, please send me an email indicating your level of interest in attending the meeting (e.g., yes, maybe).

Restoration and Synthesis of Planetary Geochemical Data
Sunday, March 15, 12:00 to 1:30 p.m., Spring Meeting Room
This event is for planetary scientists with personal archives of unpublished lunar and planetary sample data (geochemistry, mineralogy, etc.) and investigators who are interested in the development of lunar and planetary geochemical databases to discuss data recovery and learn how to compile, document, and publish their legacy data for inclusion in online databases (e.g., IEDA). We will show how these data will be synthesized and made searchable by demonstrating the PetDB data system that hosts similar data for terrestrial samples.
Jan 2015. PetDB has had multiple new versions released in the last quarter, PetDB v.2.8.3, PetDB v.2.8.4, and PetDB v.2.8.5. The new versions include several new features and bug fixes, including an improved display of the status of papers considered for inclusion in PetDB. Other features and fixes include:
- New display of mineral inclusion data.
- PetDB diamond and xenolith data now shown in the IEDA Data Browser
- Updated code to improve security and prevent SQL injection attacks
- Bug fix to disable hyperlinks on expeditions that are "Not Provided"
- Deprecated the database field "data_entered" and updated the use of "status" instead, in order to better inform users of "In Queue", "In Progress", "Completed", and "Alert" papers.
Let us know what you think about the new versions by emailing firstname.lastname@example.org, or by clicking the orange feedback button on the right-hand side of the webpage.
