Unfortunately, no data are at pres- ent available on the algal crop for the year. Other physiological variables have been considered as possible causes of the observed difference, rainfall (therefore indirectly, salinity), and amount of sunlight; but there seems to be less difference between the two years on the basis of these factors than on the basis of water tem- perature, perhaps correlated with algal Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Marine Biological Laboratory (Woods Hole, Mass. ); Marine Biological Laboratory (Woods Hole, Mass. ).
