attribute NC_GLOBAL acquisition_description String Methodology: The sulfur standards were ground using an agate mortar and pestle\nto the consistency of a fine talcum powder (approximately 10 um). A cellulose\nacetate filter was then gently dredged through a small quantity (less than 1\nmg) of powder placed on a microscope slide. This procedure produced a thin and\nalmost imperceptible coating on the filter in order to limit the thickness and\nthus self-absorption. S-NEXFS spectra of sulfate standards were collected in\nbulk mode. Self-absorption must be carefully controlled when measuring\nfluorescent X-rays from thick specimens; however, the effects of self-\nabsorption are limited to the region of the spectrum above the K-edge. In our\nrepeated measurements, the post-edge features were consistent and\nreproducible, which allows discrimination of different sulfate standards.\n \nSampling and analytical procedures: S compounds and minerals were obtained\nfrom chemical supply houses or mineral dealers. See papers cited below for\ndetails.\n \nInstruments: X-ray fluorescence microscope located at beamline 2-ID-B at the\nAdvanced Photon Source, Argonne National Laboratory. The beamline is optimized\nto examine samples over a 1\\u20134 keV energy range using a focused X-ray beam\nwith a spot size of approximately 60 nanometers squared . The energy was\ncalibrated using an elemental sulfur standard. The whiteline energy of the\nelemental sulfur standard was aligned to 2472 eV.\n \nData processing: S-NEXFS data were normalized to create a relative intensity\nvalue of approximately 1 for post-edge area of the spectra. The data were also\nprocessed using a three-point smoothing algorithm built into the software\npackage Athena to remove high-frequency noise (Ravel and Newville, 2005).

attribute NC_GLOBAL projects_0_acronym String Aerosol P
attribute NC_GLOBAL projects_0_description String NSF Award Abstract:\nPrimary nutrients, such as nitrogen and phosphorus, are critical for all life on earth, and limited quantities in the marine environment can inhibit primary productivity. Atmospheric aerosols are a significant source of these nutrients to nutrient-poor ocean regions, such as the phosphorus-limited Mediterranean Sea. The availability of phosphorus in aerosols has traditionally been linked to the composition and abundance of different phosphorus phases present. Unfortunately, investigating phosphorus composition in aerosols has been challenging due to methodological limitations until recently. In this study, researchers from Georgia Tech will use a new technique known as synchrotron-based P Near Edge X-ray Fluorescence Spectroscopy, in conjunction with X-ray fluorescence microscopy, to examine the diversity of aerosol phosphorus phases delivered to the Mediterranean Sea. By defining the relationship between air mass source region, aerosol composition, and bioavailability, results from this work will improve current knowledge of the factors regulating productivity in the Mediterranean Sea and help to clarify the potential response of this region to different climate change scenarios.\nBroader Impacts: In addition to the valuable insights this project will provide on the controls on productivity and nutrient cycling in the Mediterranean Sea, this study will further education of young scientists, broaden participation of under-represented groups in ocean science, and enhance research infrastructure.
