linear calibration graph was obtained for artificial seawater samples containing up to 2.0 mg/L of sulphide. The method was applied to the determination of sulphide in surface and bottom seawater samples. Kobe Univ. of Marcantile Mar., Fukae, Higashinada, Kobe 658, Japan. 87:6783 Grondin, D. and C.

The literature published from November 1984 to October 1986 on the application of analytical methods to the study of geological and inorganic substances is reviewed, emphasizing technical rather than theoretical aspects. Included are DC arc emission, AA, plasmas (ICP and DCP), spectrophotometric, electroanalytical, chromatographic, dissolution, nuclear activation, x-ray, and microbeam methods. New geochemical standard methods are also discussed. Seeley: USGS, P.O. Box 25046, Denver Fed. Center, Denver, CO 80225, USA. (gsb) 87:6786 MacCarthy, Patrick, R.W. Klusman and J.A. Rice, 1987.

New techniques and procedural modifications for the analysis of metals, non-metals, radionuclides, anions, and gases are described and advances in organic analysis are reported, including applications of LC and HPLC, mass spectrometry, photometry and spectrophotometry and specific techniques for detergents, pesticides and related compounds. In many cases, experimental details are included. Dept. of Chem. and Geochem., Colorado School of Mines, Golden, CO 80401, USA. (gsb)

Important physical properties preceding and partially causing hypoxia and its spatial extent are determined. Temporal trends of salinity, temperature, sigma-t, bottom dissolved oxygen, and river discharge offshore Cameron, Louisiana, are described and analyzed using monthly data. The spatial extent of hypoxia in coastal waters from Galveston, Texas, to 74 km east of Cameron was measured. A linear model estimating bottom dissolved oxygen concentrations contained salinity and temperature variables. Time series analysis revealed lags between low bottom dissolved oxygen, peak river discharge, and low salinity. The time series model using river discharge and density gradient variables more accurately predicted bottom dissolved oxygen concentrations during hypoxic events. Naval Ocean Syst.
