Anthropogenic impacts contribute to the global deterioration in the quality and productivity of marine and coastal environments. These impacts include over-exploitation, physical alteration, marine pollution, introduction of alien species and global atmospheric change. Marine environmental management (MEM) represents a set of interdisciplinary tools used by planners and managers to promote and enhance marine and coastal biological diversity. The components of marine environmental management include resource allocation, impact minimisation, pollution control and the provision of protected areas. This Chapter will examine how Australia and Canada have supported specific MEM activities including: environmental protection, conservation and planning; state of the environment reporting; protected areas; education and community networks; and ...
We investigate the excitation dynamics of Rydberg atoms in ultracold atomic
samples by expanding the excitation probability and the correlation function
between excited atoms in powers of the isolated atom Rabi frequency $\Omega$.
In the Heisenberg picture, we give recurrence relations to calculate any order
of the expansions, which ere expected to be well-behaved for arbitrarily strong
interactions. For homogeneous large samples, we give the explicit form of the
expansions, up to $\Omega^4$, averaged over all possible random spatial
distributions of atoms, for the most important cases of excitation pulses and
interactions.

Population increases and poor economic growth are underlying factors leading to the deterioration of the marine environment in many developing countries. In this article, the relationship between marine pollution and growth in PR China is analysed as a case study. Priority must be given to the resolution of existing marine environmental problems, but it is recognized that development policies and supporting strategies are required which ensure the sustainable use of the ocean and its resources while taking national and local social and economic needs into consideration.
