Giant submarine canyons: Is size any clue to their importance in the rock record? Giant submarine canyons: Is size any clue to their importance in the rock record?

Submarine canyons are the most important conduits for funneling sediment from continents to oceans. Submarine canyons, however, are zones of sediment bypassing, and little sediment accumulates in the canyon until it ceases to be an active conduit. To understand the potential importance in the rock record of any given submarine canyon, it is necessary to understand sediment-transport...

Acropora corals in Florida: status, trends, conservation, and prospects for recovery Acropora corals in Florida: status, trends, conservation, and prospects for recovery

Despite representing the northern extent of Acropora spp. in the Caribbean, most of the Florida reef line from Palm Beach through the Keys was built by these species. Climatic factors appear to have bee important agents of Acropora loss within historic (century) time frames. In the recent past (1980-present), available quantitative evidence suggests dramatic declines occurred in A...

A coastal and marine digital library at USGS A coastal and marine digital library at USGS

The Marine Realms Information Bank (MRIB) is a distributed geolibrary [NRC, 1999] from the U.S. Geological Survey (USGS) and the Woods Hole Oceanographic Institution (WHOI), whose purpose is to classify, integrate, and facilitate access to Earth systems science information about ocean, lake, and coastal environments. Core MRIB services are: (1) the search and display of information...

La mondialisation des poussieres, les vents transportent, d'un continent a l'autre, des poussieres, mai aussi des micro-organismes et des substances toxiques. Ces "passagers clandestins" pourraient transporter des maladies et modifier les ecosystems La mondialisation des poussieres, les vents transportent, d'un continent a l'autre, des poussieres, mai aussi des micro-organismes et des substances toxiques. Ces "passagers clandestins" pourraient transporter des maladies et modifier les ecosystems

Un tour d'horizon de la littérature scientifique révèle que de nombreux champs d'investigation sont jugés dignes d'intérêt de façon périodique : certaines idées sont à la mode pour un temps, puis sombrent dans l'oubli, avant de refaire surface comme si elles n'avaient jamais été émises. L'aérobiologie, c'est-à-dire l'étude des micro-organismes, tels des bactéries et des pollens...

Pathogenic human viruses in coastal waters Pathogenic human viruses in coastal waters

This review addresses both historical and recent investigations into viral contamination of marine waters. With the relatively recent emergence of molecular biology-based assays, a number of investigations have shown that pathogenic viruses are prevalent in marine waters being impacted by sewage. Research has shown that this group of fecal-oral viral pathogens (enteroviruses, hepatitis A...
