Literature and theoretical studies have demonstrated the likely existence of critical thermal transition regions for biological activity. Highly nonlinear thermal effects appear to be manifestations of higher-order phase transitions most likely in the vicinal water of the cellular systems. The effects are likely invariants in time and space. Thus, the corresponding critical temperature regions may represent absolute, upper permissible thermal pollution limits. Laboratory experiments, using some 18,000 individuals, have yielded the most accurate thermal tolerances to date for marine estuarine organisms (including macro-algae and larval stages of important food-chain organisms). Gaussian (or skewed-Gaussian) curves for lethal thermal limits were not observed. Instead an abrupt death point occurred, often within an interval of 0.5 to 1C. The temperature tolerances obtained in the laboratory conformed closely to those observed in the field. Thus upper limits found in the laboratory for Halimeda, Penicillus, and Valonia were found to be the thermal limits in the field.
