With few exceptions, we do not under- stand these effects, and in many cases we do not even know what the effects are. As we have suggested, some effects of salinity and temperature distributions and their interactions with the hydrographic structure are straightforward, but many others are not. Future studies of the shelf will have to consider the influence of hydrographic structure on many phenomena. OCEANIC OUTER MIDDLE COA

Because of spatial changes in factors affecting growth and in predator and prey distributions, considerable spatial and temporal differences in the growth and decline of biomasses occur (these are described later). All of these interactions are non- linear and therefore can be evaluated quantitatively only with thre

The environmental risks from both noise and physical disturbance can be minimized, if not elim- inated, by thoughtful planning and strict observance of sensible operating procedures. Environmental sensitivity, caution, and common sense are the main requirements for overcoming these environmental risks. The risks from normal operational discharges and accidental spills are more complex. Platform discharges Of the discharges t

Parakeet Auklets, while they have a more widespread distribution, are too scarce to cause significant shifts in the distribution maps. Both shipboard and aerial surveys tend to underestimate the densities of small alcids, and aerial surveys are especially prone to missing single birds and small groups. Aer
