Two prominent geologists were asked where they would go to find a billion bbl oil field and why. Taking a calculated approach, A.A.

Biol. mar., 24(1):35-49. Methods used to determine enzymatic decomposition of organic matter by microbiota are adapted here for use in measuring short-term activities of meiobenthos from natural sediments. Methodological conditions necessary for reliable and sensitive measurement of proteolytic and hydrolytic (aamylase and fl-D-glucosidase) activities were determined. Meiobenthic organisms appeared responsible for ~ 1 / 3 of total fl-D-glucosidase activity. Evidence for diurnal cycles in a-amylase activity is presented. Zool. Inst. und Mus., Univ.

Res., 9(3):131-181. Most of the observed changes were related to biological cycles characteristic of each habitat; however, a large portion remained unaccounted for or unpredictable. The extent of these natural fluctuations is such that only the most gross
pollution-induced effects could be assessed; pollution monitoring along rocky shores is 'likely to be an unproductive investment of time and resources.' Dept. of Zool., Manchester Univ., Manchester MI3 9PL, UK. (ahm)

Net sampling estimates generally agreed with plankton densities calculated from estimates of 'mean interanimal distances.' Small organisms were counted better with nets, delicate gelatinous forms from the submersible. Observations via submersible are potentially valuable for providing information on vertical distribution, density, behavior, color change and bioluminescence. Recommendations are offered on instrumentation and observer training. Dept. of Biol., Univ. of Victoria, B.C. V8W 2Y2, Canada. (ahm)
