Summer zero of depth is marked by a broken line; biomass in g/m2 (Shchapova, 1957). comparison of the littoral macroflora of the northern (north of Peter the Great Bay) and the southern regions. The composition of the littoral macrophytes of the northern part of the western shore of Sakhalin is very similar to that of the northern mainland coast of the Primor'e; that of the southern part, warmed by the warm cur- rent, is similar to the southern and central Primor'e. Vast fields of the commercial marine grass Phyllospadix occur at 0-5 to 15 m depth in some areas of the southern Primor'e (E. Kardakova, 1957); its mean biomass is 2 to 5 kg/m2 wet weight (0-4 to 1-0 mg/m2 dry weight). There is a great difference between the northern and southern parts of the Primor'e, principally in temperature. Maximum temperatures of the two parts differ by no less than 10° in certain months; the tides and their char- acter vary a great deal Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustration
