We present an update on the status of the 0Z Survey , an effort to datamine the Hamburg/ESO Survey to find and study in detail a large sample of extremely metal-poor Galactic halo field stars with [ Fe/H ] < -3.0 dex .
After searching 1,565 moderate resolution spectra of candidates selected from the HES , we have acquired high resolution spectra of 103 of the most metal-poor of them .
Detailed abundance analyses have been performed for all these stars .
This has resulted in the discovery of 18 new stars below [ Fe/H ] -3.5 dex and 57 below -3.0 dex .
Some results are presented regarding our search for outliers in chemical abundances of particular species among the sample of 103 stars .
Ignoring C and N , about 15 % of the sample are “ abnormal ” in some way .
Our plans to complete this project and write the final set of papers are described .
