- Summary:
- The topic of the uses and limitations of measuring stress in the oceans is addressed. The use of the term stress in this context is ambiguous. Rather than assuming that stress is an actual measurable property of oceans, one may assume that the term refers to the complex of harmful things that is going on in the oceans. that is, it is a cover term for a complex of processes and states, many of which are unknown or undefined. The appeal of the term stress used in that way is very tempting. Considerable complexity results from the fact that the ocean consists of numerous and diverse species and ecosystems each of which have various properties that have some claim to protection. Another source of complexity is the diversity of factors which constitute threats to the environment. In evaluating the concepts of ecological risk assessment, there are sources of hazardous agents, there are receptors that are affected, and there is a process by which these interact termed exposure. As a result of exposure there is some probability that the actions of the sources have caused or will cause some effect on the receptor, the risk. Assessments may be source driven; they may attempt to determine the risks associated with a waste outfall. Assessments may also be effects driven; they may attempt to determine the cause of a die-off of marine mammals or determine the likelihood of a particular rise in sea-level. Finally, they may be exposure driven. Each of these components of the causal chain might serve as measures of stress.
