When microbiologists first applied the tools of their trade to the oceans of the world, they quickly learned that water samples contained variable numbers of bacteria, depending on sample location and...
The United States Congress formed the Stratton Commission in 1966. In January 1969 the Commission released the seminal document, Our Nation and the Sea. John Knauss was on that commission, and wrote a...
For over two decades, explorers of the deep ocean have been enthralled by volcanically driven black smoker hydrothermal systems hosting organisms that live under some of the most extreme conditions on...
Gelatinous zooplankton are known to have a substantial effect on pelagic food webs by exerting top-down control on their ecosystems (Purcell and Decker, 2005), but their impact could be even greater w...
The Black Sea, a nearly enclosed and isolated environment, has suffered from severe ecological changes during the last three decades. It has been converted from an oligotrophic (less than 100 grams of...
It was not until the late 1980s that the international community became aware of the magnitude of the ecological crisis underway in the Black Sea. Major components of the ecosystem had begun to collap...
Marine ecosystems respond to climate changes at all trophic levels, from primary producers to herbivores to higher predators, in terms of growth, life history traits, and population dynamics (Stensth ...
Harmful algal blooms (HABs) are growing in frequency around the world and their effects are being recognized by ecosystems managers, scientists, and the public alike. From the serious threat to public...
Marine and fresh waters team with life, much of it microscopic, and most of it harmless; in fact, it is this microscopic life on which all aquatic life ultimately depends for food. Microscopic algae a...
Experimental and comparative methods have been referred to as "the two great methods of science" (Mayr, 1982). To reach valid scientific conclusions, the processes of interest should be studied throug...
Coastal embayments are a broad category of an ecosystem type that may be loosely defined as an enclosed or semi-enclosed aquatic environment along a land-mass margin. Embayments are highly diverse, re...
Successful management of the coastal environment requires sound knowledge of the biological, chemical, and physical processes governing the growth, retention, dispersion, and transport of water consti...
The California Current, Humboldt Current, Canary Current, Iberian Coastal System, and Benguela Current represent five Large Marine Ecosystems (LMEs) associated with eastern boundary upwelling regimes ...
Cultural eutrophication, the pollution of coastal waters by nutrients, is a result of population growth, food production (agriculture, animal operations and aquaculture), and energy production and con...
Harmful algal blooms (HABs) represent a diverse range of phenomena that universally share only two characteristics: they produce effects on ecosystems or food resources that humans perceive as harmful...
