Spectrophotometric procedure using rhodamine B for determination of submicrogram quantities of antimony in rocks
Marian M. Schnepfe
1973, Talanta (20) 175-184
A spectrophotometric procedure using Rhodamine B is given for the determination of antimony in mineralized rocks after its separation as stibine. A study of the Rhodamine B reaction points to the importance of the order of addition of reagents in enhancing sensitivity and increasing the stability...

Ground-water hydrology of the Hollister and San Juan Valleys, San Benito County, California, 1913-68
Chabot Kilburn
1973, Open-File Report 73-144
The Hollister and San Juan Valleys are within the Gilroy-Hollister ground-water basin. That part of the ground-water basin underlying the valleys consists of three subbasins each of which contains two or more ground-water subunits. The subbasin and subunit boundaries are formed by known or postulated faults, folded sedimentary rocks, and...
A review of benthic faunal surveys in San Francisco Bay
Frederic H. Nichols
1973, Circular 677
During the past 60 years, considerable effort has been expended in studies of the relations of the biotic community and physicochemical characteristics of San Francisco Bay water. In very recent years these studies have emphasized the relations between the 'state of health' of bottom-living invertebrates (the benthos) and the levels...
