McLane pumps were deployed at eight depths throughout the water column from near the sea surface (~14 meters) to near the seafloor (~250 meters). The first deployment occurred in the Wilkinson Basin and the second occurred in the Jordan Basin. Small (1-51 micrometer (µm)) and large particle (>51 µm) concentrations of total carbon, total nitrogen, and inorganic carbon (PC, PN, and PIC, respectively) are presented, along with small particle isotopic compositions (13C, 15N) of these phases, particulate thorium-234, and RAP234 (a resuspension proxy associated with particulate thorium-234). Depth profiles demonstrate typical particulate carbon shapes. The PIC demonstrates a peak near the seafloor, indicating the potential presence of a nepheloid layer. This feature does not appear in the PC data. The isotopic composition of the PIC demonstrates uniquely negative values throughout the water column. Small particle thorium-234 activities were consistently larger than the large particle activities at all depths and small particle RAP234 activities indicate possible resuspension in the bottom ~50 m of the water column. These data were collected by Drs. Adam Subhas (WHOI) and Erin Black (UR). Data processing and preparation were completed by Dr. Subhas, Dr. Black, and Karine Holmes (UR).\n\ncdm_data_type = Other\nVARIABLES:\nCRUISE_ID (unitless)\nSTNNBR (unitless)\nlatitude (degrees_north)\nlongitude (degrees_east)\ntime (Deploy_iso_datetime_utc, seconds since 1970-01-01T00:00:00Z)\nDATE_DEPLOY (unitless)\nTIME_DEPLOY (unitless)\nRecover_ISO_DateTime_UTC (seconds since 1970-01-01T00:00:00Z)\nDATE_RECOVER (unitless)\nTIME_RECOVER (unitless)\nCASTNO (unitless)\ndepth (m)\nPUMPVOL_L (liters (L))\n...
