which emphasizes the need for large-scale, long-term monitoring, five papers on general aspects (patch- iness, methods, national efforts), and two papers on monitoring sea level changes. There are also papers on seal, bird, benthos, and fish monitoring, on mussels as eutrophication indicators, and on eco- system research (modelling, management). Sympo- sium conclusions and recommendations are pre- sented in the final paper. (gsb)

tigation of the ecosystem of Kraternaya Bight (Knrile Islands). Soy. J. mar. Biol. (a translation of Biol. mor, A kad. Nauk SSSR), 15(3): ! 39-221; 14 papers.

Data are presented from a series of interdisciplinary expeditions to the Kraternaya Bight, in which sublittoral volcanic activity and associated microbial mats and dense fauna were discovered. Island physical geography, submarine volcanism, metal geochemistry, DOM, and fluxes of oxygen, chlo- rophyll, and biogenie elements were studied. Papers on bacterioplankton, extreme thermophilic bacteria, diatoms, microbial mats, bivalves, and sedimentary processes (sulfate reduction, methanogenesis) are also included. Inst. of Mar.

mutual relationship between the monitoring and modelling of estuarine ecosystems, llelgol~nder Meeresunters, 43(3-4):537-548.

A general simulation model developed for the Ems �9 Estuary, to describe the main carbon flow through

the foodweb, was applied for monitoring purposes. In this model, the estuary is divided into five compartments, in each of which a pelagic, an epibenthic and a benthic submodel operates. Results indicate that the reaches, which represent the beginning and the end of a gradient in the estuary, are also very suitable for monitoring the quality status of this estuary in terms of production and standing stock of groups of organisms. The need to use monitored data from the boundaries of those ecosystems as input in simulation models is dis- cussed. Rijkswaterstaat, Tidal Waters Div., P.O. Box 207, 9750 AE Haren, Netherlands.

lander Meeresunters~ 43(3-4):263-273.

Patchy distribution of animals is a common phe- nomenon; in many cases the causes are obscure. Patchy distribution of zooplankton is not understood and was not even expected in the fast turbulent currents of the well mixed tidal channels of the Wadden Sea. This patchiness is shown here for a number of plankton species. Methods commonly used for monitoring plankton usually neglect patchy distribution; thus results suffer. Interpretation of such data can be misleading; an overestimate or underestimate of population density may be the result. Sound quantitative data can only be obtained by great effort in terms of work and money. Netherlands Inst. for Sea Res., P.O. Box 59, 1790 AB Den Burg, Texel, Netherlands.

plankton and nutrients from a Lagrangian drifter off northern California. J. geophys. Res, 95(C6): 9393-9409.

A Lagrangian drifter was deployed in a cold filament off northern California as part of the Coastal Transition Zone program. Optical, chemical, and biological properties changed considerably as the drifter moved offshore in the cold filament. Con- centrations of phytoplankton chl increased rapidly in the first two days, in parallel with the disap- pearance of nitrate and nitrite. After this initial period, chi decreased gradually over the next six days with prominent diurnal fluctuations present in the last three days. The phytoplankton community became increasingly dominated by large centric diatoms throughout the deployment. These results are generally consistent with results from other upwelling studies.
