Nov 2014. The iSamplES and C4P (Collaboration and Cyberinfrastructure for Paleogeoscience) Research Coordination Networks will be holding a joint event at AGU for early career scientists who deal with samples in their research.
This is a lunchtime forum to meet and discuss creating and storing digital sample information, whether earth materials samples are solid, liquid, or gas, or even experimental run products. We will chat about developing best practices for sampling and preserving sample information to make our growing collections easily manageable and more useful.
When: Thursday December 18, 2014 12:15pm-13:45pm
Where: At AGU, San Francisco, CA
Lunch will be provided, plus a limited number of stipends (cost of early registration) will be available to those who register for and participate in the forum.
This forum is for graduate students and early career scientists (those within five years of completion of a Ph.D). The project is sponsored by the NSF Earthcube Research Coordination Networks iSamplES and C4P (Collaboration and Cyberinfrastructure for Paleogeoscience). The results will help guide planning and development of an “internet of physical samples” for the earth sciences.
If you are interested, please fill out a simple application form by November 15, 2014.
Sept 2014. The new version of PetDB, v.2.8.1, includes several new features and bug fixes, including improved map view near the poles and a new quick access button to the growing xenolith data collection. Other features and fixes include:
- Modified Diamond search now defaults to Mineral analyses instead of Bulk Rock (because the vast majority of Diamond data is on mineral analyses).
- New dynamic link to select PetDB vocabularies (on Vocabulary page)
- Improved display of sample classifications by showing all classifications on a sample and which reference that classification came from.
- New display of "In Progress" references in the Reference tab, allowing PetDB users to preview upcoming data related to their search query.
- Bug fix to point popup links to the correct station on the Sample map page.
- Bug fix to remove duplicate "Alteration" comments in sample view.
Let us know what you think about the new version by emailing firstname.lastname@example.org, or by clicking the orange feedback button on the right-hand side of the webpage.
Aug 2014. EarthChem would like to thank all its users who recently responded to our survey about the use and utility of EarthChem data systems for their research and teaching. These comments (examples shown below) are critical to demonstrate the utility of these data resources to the community and to the National Science Foundation (NSF) and will inform future developments. If you would like to comment on how EarthChem tools have been useful in your own work or suggest ways they could be more useful, please send us an email at email@example.com.
… The availability of the data [in PetDB] in a form that can quickly be used for graphing and comparison with other data is invaluable. It has made my research more efficient and has saved me many hours of typing in data.
...I find [PetDB] one of the most useful databases available.
...PetDB has been of considerable help and has enabled us to perform comparisons with well-spread geochemical data to oceanic basalts all around the world….
Both PetDB and EarthChem are very important in my petrologic/geochemical research as they provide “instant” access to a wealth of background data and information that would normally take lots of time and effort to build...
The PetDB is indispensable in this era of research. Where so much data exists, and in the spirit of open sourcing, we need a resource that allows all scientists to use collected data quickly, and efficiently. PetDB is doing a very good job at this.
As a retired scientist still interested in research problems, I find accessing information through a public library difficult to impossible. The EarthChem Library is an indispensable resource.
...PetDB ... was a great tool to demonstrate the principles we discussed in class with actual data.
Our course had modules involving the systems that were easy to follow along with and I found the data-download process to be simple and user-friendly.
...PetDB is an especially good teaching tool for beginning graduate students that have now collected their first data. The database makes it much easier for them to put their data in a larger context.
I regularly use PetDB and EarthChem together with GeoMapApp during the laboratory work of my course ... I use these tools to make students aware of the enormous potential of the on line chemical resources and availability of petrologic tools. … Forcing the student to build up the map makes them more attentive to map details.
...Students answer very positively to this approach to describe petrologic processes because [it is] more akin to their "natural" propension of playing with computers and informatic tools and the possibility of imaging data by using plots and maps.
Jun 2014. Today, June 9, 2014, we have reached the 500th citation of the PetDB database! Since its inception in 2001, PetDB data has been cited 500 times in the published and peer-reviewed scientific literature.
Use of PetDB data ranges from decoding subduction processes, to understanding volatile fluxes, to modeling of the Earth's core, proving the value of highly accessible, well-integrated data sets to the research community.
The 500th citation is:
