(Collaborative Research: From hot to cold in the dark - shifts in seafloor massive sulfide microbial communities as physical and geochemical conditions change after venting ceases) Synchrotron micro-probe X-ray diffraction data were collected for seafloor sulfide deposits. Seafloor sulfide mineral samples were collected from hydrothermally active chimneys and inactive off-axis massive sulfide deposits at East Pacific Rise (EPR) 9.50°N in 2019-2021 on cruise AT42-09. Samples were collected using the HOV Alvin. Samples were placed in a positive-pressure glove bag flushed with N2 (g), sparged with N2, heat-sealed into mylar bags containing Anaeropaks, and stored at -20°C.\n\nEpoxy embedded petrographic thin sections were created using these samples. Subsamples were dried for 24 hours under N2 (g), vacuum embedded in epoxy resin (Struers EpoFix Resin, 1L kit: Part #40200030) following manufacturer's guidelines, and cured under N2 (g) for 24 hours. Each epoxy-embedded sample was pre-cut using a wafering saw then sent to Spectrum Petrographics, Inc. (Washington, USA) for preparation as 30 micron thick, double-polished thin sections mounted on quartz slides using methods to limit sample exposure to water and ambient air. When not in use, thin-sections were stored under N2 (g) to limit oxidation. Thin sections were analyzed for X-ray diffraction at the X-ray Fluorescence Microprobe beamline \"XFM\", National Synchrotron Light Source II (NSLS II), Brookhaven National Laboratory, NY.\n\ncdm_data_type = Other\nVARIABLES:\nCruise (unitless)\nFile_name (unitless)\nSample_name (unitless)\nsample_descrip (Time, unitless)\nHydrotherml_vent_category (unitless)\nLocation (unitless)\nlatitude (Lat_dd, degrees_north)\nlongitude (Lon_dd, degrees_east)\ndepth_f (Depth_mbs, m)\nHdg (degrees)\nDate_collected (unitless)\nTime_collected (unitless)\ntime (Iso_datetime_utc, seconds since 1970-01-01T00:00:00Z)\n https://erddap.bco-dmo.org/erddap/metadata/fgdc/xml/bcodmo_dataset_937020_v1_fgdc.xml https://erddap.bco-dmo.org/erddap/metadata/iso19115/xml/bcodmo_dataset_937020_v1_iso19115.xml https://erddap.bco-dmo.org/erddap/info/bcodmo_dataset_937020_v1/index.htmlTable https://www.bco-dmo.org/dataset/937020 (external link) https://erddap.bco-dmo.org/erddap/rss/bcodmo_dataset_937020_v1.rss https://erddap.bco-dmo.org/erddap/subscriptions/add.html?datasetID=bcodmo_dataset_937020_v1&showErrors=false&email= BCO-DMO bcodmo_dataset_937020_v1
