Marine pollution occurs today in varied formschemical, industrial, and agricultural-and the sources of pollution are endless. In recent history, we''ve seen oil spills, untreated sewage, eutrophication, invasive species, heavy metals, acidification, radioactive substances, marine litter, and overfishing, among other significant problems. Though marine pollution has long been a topic of concern, it has very recently exploded in environmental, economic, and political debate circles; scientists and non-scientists alike continue to be shocked and dismayed at the sheer diversity of water pollutants and the many ways they can come to harm our environment and our bodies.In Marine Pollution: What Everyone Needs to Know, Judith Weis covers marine pollution from many different angles, each fascinating in its own right. Beginning with its sources and history, the book describes in detail each common pollutant, why exactly it is harmful, why it may draw controversy, and how we can prevent it from destroying our aquatic ecosystems. Weis discusses topics like what actually happened with the Exxon Valdez, and why Harmful Algal Blooms are a serious concern. Later chapters will discuss pollutants that are only now surfacing as major threats, such as pharmaceuticals, personal care products, and metal nanoparticles, and explain how these can begin in the water and progress up the food chain and emerge in human bodies. The book''s final section will discuss the effects of climate change and acidification on marine pollution levels, and how we can reduce pollution at the local and global levels.

Monitoring changes in the intertidal zone of rocky shores has never been more critical. This sensitive habitat at the interface of land and ocean may well be the marine equivalent of the canary in a coal mine as we advance into an era of global climate change. This handbook describes effective methods and procedures for monitoring the ecological and environmental status of these areas. Written by three collaborating authors with extensive field experience, it provides critical discussions and evaluation of the various sampling techniques and field procedures for studies of intertidal macroinvertebrates, seaweeds, and seagrasses. Rather than prescribing standard protocols or procedures, the authors break down the decision-making process into various elements so investigators can become aware of the advantages and disadvantages of choosing a particular method or approach.Chapters discuss topics such as site selection, field sampling layouts and designs, selection of sampling units, nondestructive and destructive methods of quantifying abundance, and methods for measuring age, growth rates, size, structure, and reproductive condition.
