  Glossary, "Investigating Marine Life", Census of Marine Life
Water from cold seeps is the same temperature as the surrounding seawater.
Cold seeps are called "cold" to contrast them with the hot water from hydrothermal vents.
Hydrothermal vents and seeps, seeps are similar to vents, but are generally much cooler and often don't have as high a level of biodiversity.

  Cold Seep Communities-Section III
In the Monterey Bay region, cold seep communities were first discovered in the axial valley of the Monterey Submarine Canyon during dives in the research submersible ALVIN (Embley et al.
The presence of seep communities was suspected in Monterey Bay from samples of vesicomyid clams (bivalves associated with seeps) dredged from the bay during research cruises (J. Nybakken, pers.
In addition, the distribution of clam species within individual seeps varies according to localized gradients in sulfide concentration, similar to the zonation of flora and fauna along a desiccation gradient in the rocky intertidal zone.

 AAAS - AAAS News Release
On average, the first appearance of cold seep mollusk genera in the geological record is a full epoch earlier than that of marine mollusks in general, according to Steffen Kiel and Crispin Little of the University of Leeds.
Cold seeps may have been—and continue to be—safe harbors for the mollusks, protecting them from mass extinctions and possible abrupt oxygen changes in the seas, the researchers found.
Cold seeps are places where fluids rich in hydrogen sulfide and methane leak up through the ocean floor, creating a unique chemical environment where hardy bacteria process the sulfide and methane.

 SIMoN -- Monterey Bay National Marine Sanctuary
Seamounts and cold seeps are the oases of the deep sea.
The deep sea is a dark and cold environment that includes a variety of habitats from the midwater to the abyss that are populated by a wide array of animals, specially adapted to live under the tremendous water pressure and low oxygen level of this harsh environment.
In cold seeps, bacterial mats are at the base of the food web and use the chemical energy in a similar way that plants use the energy from the sunlight.

 WWF - Deep sea ecology: hydrothermal vents and cold seeps
Apart from temperature and the chemical used for energy, a major difference between vent and cold seep ecosystems is the rate of growth.
Seep tube worms, for example, are thought to live for up to 250 years.
The deepest cold seep ecosystem discovered so far is located in the Sea of Japan at a depth of 5,000 to 6,500m.

 Levin Seeps
Scripps scientist Kevin Brown reports that the geological setting of the cold seeps along the crest of a plunging anticline suggests updip migration of fluids and gases from the subsurface hydrates.
Most studies of cold seeps have focused on the larger fauna such as clams and tubeworms, or the chemosynthetic bacteria that are unique to these environments.
Comparison of the Eel River seep communities with those observed during previous cold seep surveys off the coasts of Alaska and Oregon reveal geographical diversity in the ecosystem's structure and function, including highly variable reliance on methane.

or methane--sometimes as methane-hydrate ice--and hydrogen sulfide) and oil seep out of the sediments and also provide abundant energy for eubacteria, and archaea, which are the basis of a "gas-powered" foodchain.
Seep areas are littered with small to huge blocks of carbonate rocks, thought to be formed by precipitation from seep waters as a byproduct of microbial metabolism.
These are methane and sulfide seeps at various locations in the Pacific.

These are the cold seeps and related environments, where oil and methane gas are bubbling up from undersea sediment layers.
we now suspect that cold seeps are a common component of continental borderlands, where fluid flow through the continental crust may be controlled by various processes.
Fluid seepage at one seep region (Mt. Crushmore) is suspected to result from artesian flow of rainwater which enters a sandstone aquifer (Purisima Formation) in the Santa Cruz mountains and is released along the walls of Monterey Canyon after percolating downslope 1000 m or mor...

Near cold seeps in the Eastern Mediterranean, Sbastien Duperron from Universit Pierre et Marie Curie in France has found unique bacterial symbiosis with mussels.
His observations of the fauna around coastal margin hydrocarbon seeps in the Gulf of Mexico have revealed a habitat rich in biological activity and without a need for symbionts to extract nutrients.

 Extraordinary Life Found Around Deep-Sea Gas Seeps
Cold seeps are areas of the seafloor where methane gas or hydrogen sulphide escapes from large stores deep below.
Like hydrothermal vents, cold seeps support unique communities of animals living in symbiosis with microbes that can convert these energy-rich chemicals to living matter (a form of 'chemosynthesis') in the absence of sunlight.
A few cold seep sites were previously known along the New Zealand coast from geological and biogeochemical studies of the continental margin.

 MBARI - Molecular Ecology - Cold Seeps
Cold seeps are areas where methane and sulfide-rich fluids seep into the substrate of the ocean floor.
Like the species that inhabit hydrothermal vents, seep animals are also dependent on sulfur-oxidation by symbiotic bacteria for survival.
After further lab work, we intend to use this technology in a shallow water environment to investigate the effectiveness in detecting and collecting the larvae of shallow-living barnacle and molluscs.

His observations of the fauna around coastal margin hydrocarbon seeps in the Gulf of Mexico have revealed a habitat rich in biological activity and without a need for symbionts to extract nutrients.
MacDonald found that the productivity of deep-water seeps is overwhelmingly based on chemosynthesis (deriving energy from chemical compounds instead of light) and also some chemoautotrophic symbiosis (using a symbiont to derive energy from chemical compounds).

 Dr. Eva Ramirez-Llodra: Conversations: Who's Who in the Census: Census of Marine Life Portal
The dives I did with the submersible Johnson Sea Link (Dr Craig Young, HBOI, USA) in the Gulf of Mexico cold seeps and with the Nautile (Dr Daniel Desbruyères, Ifremer, France) on the hydrothermal vents in the Mid-Atlantic Ridge were simply unique and I consider myself extremely lucky to have done them..
Vents were only discovered in 1977 in the Galapagos Rift, and the cold seep associated fauna only in 1984 in the Gulf of Mexico, and we know only a very small fraction of all vents and seeps in the world.
I have obtained results showing that the number of eggs produced by deep-sea species can vary depending on the energy available in their habitat, but that the gametogenetic processes that result in the production of eggs and sperm are specific of the species and there seems to be no special adaptations in deep-sea animals.

Then, as water seeps down through the ground, it may dissolve a little bit of the minerals and other substances that could be present.
If the water has an odor, and the outside water didn't, then there is a source inside the home that is causing the odor.
These types of filters can be installed on a water line supplying the cold water to the faucet from which you get water that you drink.

To go with them, to sit in their kitchens or on their couches and feel the cold air settling on my sweaty skin felt every bit as delicious as a glass of ice water going down one gulp at a time.
The heat of summer seeps into every corner of a dirty house.
