   WORK EFFORT NARRATIVE: CO-I ECONOMOS WAS THE LABORATORY MANAGER FOR THE UCLA SECONDARY IONIZATION MASS SPECTROMETRY (A.K.A. ION MICROPROBE) LABORATORY FOR FOUR YEARS. DURING HER TIME AT UCLA, SHE DEVELOPED THE METHOD OF ANALYZING SULFUR ISOTOPE RATIOS IN APATITE AND HAS CHARACTERIZED THE ONLY KNOWN HOMOGENEOUS STANDARD FOR THIS ANALYSIS. SHE SUBSEQUENTLY DEVELOPED THE SYNCHRONOUS COLLECTION OF S AND CL ISOTOPES THAT WILL BE UTILIZED FOR THIS PROPOSAL. SHE HAS CONDUCTED THESE IN-SITU ANALYSES USING THE SAME INSTRUMENT THAT IS PROPOSED HERE, THE CAMECA 1290. CO-I ECONOMOS WILL UNDERTAKE THE CAREFUL SAMPLE PREPARATION REQUIRED FOR HIGH-PRECISION IN-SITU ISOTOPE ANALYSIS. SHE WILL TUNE THE INSTRUMENT FOR THE ANALYSIS, WHICH MUST BE DONE USING INDIVIDUALIZED PARAMETERS THAT ARE DETERMINED SPECIFICALLY FOR THE CONCENTRATIONS IN THE SAMPLES OF INTEREST. SHE WILL LEAD THIS COMPONENT OF THE ANALYTICAL EFFORT AND REDUCE AND PREPARE ALL DATA INTO A FORMAT THAT CAN BE USED FOR EVALUATION OF PROJECT HYPOTHESES AND FOR PUBLICATION. SHE WILL ALSO PARTICIPATE IN THE WRITING, FIGURE AND TABLE PREPARATION OF RESULTING PUBLICATIONS.
