During July--August 1976, waters and sediments were collected from streams and lakes over an area of 100,000 km/sup 2/ around Kotzebue, Alaska, as part of the National Uranium Resource Evaluation Hydrogeochemical and Stream Sediment Reconnaissance. The work provides multielement results for 949 waters and 886 sediments from 979 locations. Of these, 492 waters and 452 sediments are from 517 locations in the proposed Chukchi Imuruk Reserve; 447 waters and 423 sediments are from 451 locations in the proposed Selawik Wildlife Refuge; and 10 waters and 11 sediments are from 11 locations in the proposed Cape Krusenstern Monument. The field data, with concentrations of 13 elements in the waters and 43 in the sediments, are presented, and the sample locations are shown on accompanying plates. The waters were analyzed for uranium by fluorometry or delayed-neutron counting and calcium, chromium, cobalt, copper, iron, lead, magnesium, manganese, molybdenum, nickel, titanium, and zinc by plasma-source emission spectrography. The sediment samples were analyzed for uranium by delayed-neutron counting, beryllium and lithium by arc-source emission spectrography, bismuth, cadmium, copper, lead, nickel, niobium, silver, tin, and tungsten by x-ray fluorescence, and aluminum, antimony, barium, calcium, cerium, cesium, chlorine, chromium, cobalt, dysprosium, europium, gold, hafnium, iron, lanthanum, lutetium, magnesium, manganese, potassium, rubidium, samarium, scandium, sodium, strontium, tantalum, terbium, thorium, titanium, vanadium, ytterbium, and zinc by neutron activation. Uranium to thorium ratios in each sediment are also provided.
