[See History of NURE HSSR Program for a summary of the entire program.]
Totals of 1,216 sediment and 1,128 water samples were collected from 1,225 locations in the Philip Smith Mountains quadrangle as part of the Los Alamos Scientific Laboratory (LASL) Philip Smith Mountains Quadrangle NURE Hydrogeochemical and Stream Sediment Reconnaissance (HSSR) study. Samples were collected during August of 1978. The sediment samples were analyzed by LASL for uranium and up to 43 additional elements, but LASL was unable to complete the Philip Smith Mountains quadrangle data release report. The data were sent to and released by the Bendix Field Engineering Corporation in Grand Junction, Colorado only as a microfiche GJBX-259(81) report. This report does not give any details on the sample collection or analytical methods used for these samples.
LASL sent the 1,128 water samples from the Philip Smith Mountains quadrangle to the Oak Ridge Gaseous Diffusion Plant (ORGDP) for analysis. These samples were analyzed for uranium and up to 27 additional elements and the results were released by ORGDP in the GJBX-163(81) report.
Personnel of the U.S. Bureau of Mines, Alaska Field Operations Center, Fairbanks, collected 416 rock and 1,584 sediment samples "in 6 project areas in central and northeastern Alaska." The samples were sent to LASL for analysis (uranium and up to 42 other elements) and the results were released by Bendix Field Engineering Corporation of Grand Junction, Colo. in the GJBX-33(80) report. This report includes results for 106 sediment samples collected from within the Philip Smith Mountains quadrangle. However, the report does not include any site description data, and sample locations could only be identified on plates accompanying the report.
The following is a list of NURE sample types collected for these studies in the Philip Smith Mountains quadrangle.
| Sediment Sample Type | Number of Samples | Water Sample Type | Number of Samples |
|---|---|---|---|
| Wet Streams | 992 | Streams | 881 |
| Dry Streams | 89 | Lakes | 246 |
| Wet Lakes | 240 | Springs | 1 |
| Wet Springs | 1 | ||
| Total Sediments | 1,322 | Total Waters | 1,128 |
These Philip Smith Mountains quadrangle samples were analyzed by one or more of the following methods:
Sediment Samples
Water Samples
The sediment data in the NEW-FORMAT NURE data files consist of 1,216 reformatted sediment records from the GJBX-259(81) LASL sediment data report and 106 reformatted sediment records from the GJBX-33(80) U.S. Bureau of Mines report. The water data in the NEW-FORMAT NURE data files consist of 1,128 reformatted water records from the GJBX-163(81) ORGDP water data report. Any changes in the data or problems found are noted in the REFORMAT comment field.
The site locations for samples from the U.S. Bureau of Mines studies were only identified on plates that accompanied the U.S. Bureau of Mines GJBX-33(80) report. These locations were digitized from the plates and the coordinates added to the sediment file. Occasionally, a sample site was plotted more than once or not at all. Problems with the coordinates for these samples are noted in the REFORMAT comment field.
The NURE HSSR data are now available online in two databases: The sediment database (also includes data for soils and some rocks) at http://tin.er.usgs.gov/nure/sediment/ and the water database at http://tin.er.usgs.gov/nure/water/. From these two websites, NURE HSSR data can be selected, examined, summarized, and downloaded by political boundaries (State and County), by quadrangle (1:250,000-scale, 1:100,000-scale, and 1:63,360-scale for Alaska or 1:24,000-scale for the Lower 48 States), and by hydrologic unit (drainage region, subregion, river basin, or sub-basin). Selected data can be downloaded as a dBase file, a shapefile, an HTML table, or ASCII text (tab- or comma-delimited).
Philip Smith Mountains Quadrangle Sediment Data - 1,322 records
Philip Smith Mountains Quadrangle Water Data - 1,128 records
Water samples from this quadrangle are reported to have been acidified with nitric acid but NOT filtered in the field.
The ORGDP fluorometric procedure for uranium required each water sample to be centrifuged before taking an aliquot for analysis. It is not clear whether water samples analyzed by emission spectrometry were also centrifuged prior to analysis.
Values of 99999 are as reported in the GJBX publications and may reflect values above determination limits.
Sediment samples from the U.S. Bureau of Mines GJBX-33(80) report were assigned a SAMPTYP of 12 but no information was available on whether these samples were wet or dry.
LASL compiled all of the regional HSSR data from Alaskan NURE studies and produced a report [GJBX-32(83] that graphically displays the distribution of selected elements for most of the State. No additional geochemical data were released with this report.
