The increased use of hydropower is currently driving the greatest surge in global dam
construction since the mid-20th century, meaning that most major rivers on Earth are now …

The element silicon (Si) is required for the growth of silicified organisms in marine
environments, such as diatoms. These organisms consume vast amounts of Si together with …

Chemical weathering is an integral part of both the rock and carbon cycles and is being
affected by changes in land use, particularly as a result of agricultural practices such as …

Nutrient fluxes to coastal areas have risen in recent decades, leading to widespread hypoxia
and other ecological damage, particularly from nitrogen (N). Several factors make N more …

A primary focus of coastal science during the past 3 decades has been the question: How
does anthropogenic nutrient enrichment cause change in the structure or function of …

The extensive development of surface and subsurface drainage systems to facilitate
agricultural production throughout North America has significantly altered the hydrology of …

The net inputs of silicic acid (dissolved silica) to the world ocean have been revised to
6.1±2.0 teramoles of silicon per year (1 teramole= 1012 moles). The major contribution …

Suspension-feeding bivalves serve to couple pelagic and benthic processes because they
filter suspended particles from the water column and the undigested remains, ejected as …

Aquatic ecosystems respond variably to nutrient enrichment and altered nutrient ratios,
along a continuum from fresh water through estuarine, coastal, and marine systems …

Phytoplankton blooms are prominent features of biological variability in shallow coastal
ecosystems such as estuaries, lagoons, bays, and tidal rivers. Long‐term observation and …
