National Geochemical Database—Reformatted Data from the National Uranium Resource Evaluation (NURE) Hydrogeochemical and Stream Sediment Reconnaissance (HSSR) Program

Brief History and Description of Data

[See History of NURE HSSR Program for a summary of the entire program.]

Totals of 14 sediment and 15 water samples were collected from 15 locations during June of 1978 within the Middleton Island quadrangle as part of the Los Alamos Scientific Laboratory (LASL) Middleton Island Quadrangle NURE Hydrogeochemical and Stream Sediment Reconnaissance (HSSR) study. All samples were analyzed by LASL for uranium, and sediment samples were also analyzed for up to 43 additional elements. When LASL was unable to complete the Middleton Island quadrangle data release report, the data were sent to the Bendix Field Engineering Corporation in Grand Junction, Colorado and subsequently published as the microfiche GJBX-18(82) report. This report does not give any details on the sample collection or analytical methods used for these samples.

The following is a list of NURE sample types collected in the Middleton Island quadrangle.

*Summary of Middleton Island quadrangle sample types.*
Sediment Sample Type	Number of Samples	Water Sample Type	Number of Samples
Wet Streams	14	Streams	15
Total Sediments	14	Total Waters	15

These Middleton Island quadrangle samples were analyzed by one or more of the following methods:

Sediment Samples

LA1: Los Alamos Delayed-Neutron Counting Analysis of sediments for U.
LA3: Los Alamos Energy Dispersive X-Ray Fluorescence Analysis of sediments for Ag, As, Bi, Cd, Cu, Nb, Ni, Pb, Se, Sn, W and Zr.
LA5: Los Alamos Neutron Activation Analysis of sediments for Al, Au, Ba, Ca, Ce, Cl, Co, Cr, Cs, Dy, Eu, Fe, Hf, K, La, Lu, Mg, Mn, Na, Rb, Sb, Sc, Sm, Sr, Ta, Tb, Th, Ti, V, Yb, and Zn.

Water Samples

LA6-FL: Los Alamos Fluorometry Analysis of waters for U.

Composition of the NEW-FORMAT NURE Data Files

The data in the NEW-FORMAT NURE data files consist of reformatted records from the GJBX-18(82) report. Any changes in the data or problems found are noted in the REFORMAT comment field.

Download The Data

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).

Middleton Island Quadrangle Sediment Data - 14 records
Middleton Island Quadrangle Water Data - 15 records

Notes for Data Users

Water samples from this quadrangle are reported to have been acidified with nitric acid but NOT filtered in the field.

Other NURE Geochemical Data for the Middleton Island Quadrangle

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.
