Mineral evolution posits that Earth's near-surface mineral diversity gradually increased through an array of chemical and biological processes. A dozen different species in interstellar dust particles that formed the solar system have evolved to more than 4500 species today. Previous work from Carnegie's Bob Hazen demonstrated that up to two thirds of the known types of minerals on Earth can be directly or indirectly linked to biological activity. Now Hazen has turned his focus specifically...

Pacific Carbon Pump Speeds Up In Summer
2012-02-09 04:44:07

An international team of scientists led by University of Hawaiʻi at Mānoa oceanographer David Karl has documented a regular, significant and unexpected increase in the amount of particulate matter exported to the deep sea in the North Pacific Subtropical Gyre. They suspect the previously undocumented phenomenon may be a response to day length, a general phenomenon known as photoperiodism. Measuring the biological carbon pump Using 13 years of...

Futuristic robots may be coming soon to an ocean near you. Sensorbots are spherical devices equipped with biogeochemical sensors, that promise to open a new chapter in the notoriously challenging exploration of earth´s largest ecosystem–the ocean. The devices are being designed and developed in the laboratory of Professor Deirdre Meldrum, ASU Senior Scientist and Director of the Center for Biosignatures Discovery Automation at Arizona State University´s Biodesign Institute....

The Natural History Museum in London said on Friday that it is seeking the public's advice in naming a new species of sea-dwelling worm. The unnamed worms are known as annelids and the species spends its time about 6,500 feet below the surface of the sea in Antarctic. "Our goal is to show that taxonomy, the scientific discipline of naming new species, is interesting, fun and crucial to the advancement of science," zoologist at the National History Museum, Adrian Glover, said in a press...

Census of Marine Life reports in anthropogenic impact on deep sea The oceans cover 71% of our planet, with over half with a depth greater than 3000 m. Although our knowledge is still very limited, we know that the deep ocean contains a diversity of habitats and ecosystems, supports high biodiversity, and harbors important biological and mineral resources. Human activities are, however increasingly affecting deep-sea habitats, resulting in the potential for biodiversity loss and, with this,...

Study finds connection between atmospheric events and the deep ocean Researchers from Woods Hole Oceanographic Institution (WHOI) and their colleagues have discovered that massive, swirling ocean eddies"”known to be up to 500 kilometers across at the surface"”can reach all the way to the ocean bottom at mid-ocean ridges, some 2,500 meters deep, transporting tiny sea creatures, chemicals, and heat from hydrothermal vents over large distances. The previously unknown deep-sea...

By studying the tolerance of marine invertebrates to a wide range of temperature and pressure, scientists are beginning to understand how shallow-water species could have colonized the ocean depths. Scientists believe that climate changes at various at various times during Earth's history caused extinctions of creatures living at bathyal (1,000"“4,000 meters) and abyssal (>4,000 m) depths. These extinctions were apparently followed by re-colonization of the deep sea by shallow-water...

Analysis of a comprehensive database has revealed strong links between biological productivity in the surface oceans and patterns of biomass and abundance at the seafloor, helping to explain large regional differences. The research was conducted by an international, multi-institutional research team including scientists from the National Oceanography Centre (NOC), and incorporated data from the Census of Marine Life (CoML). The vast majority of the biological production in the world's oceans...

Frontiers in Ecology and the Environment issue examines the basic elements of life In the search for life on Mars or any planet, there is much more than the presence of carbon and oxygen to consider. Using Earth's biogeochemical cycles as a reference point, elements like nitrogen, iron and sulfur are just as important for supporting life. As explored in studies published in February's open-access Special Issue of Frontiers in Ecology and the Environment, the most basic elements work together...

Researchers have found compelling evidence for an extensive biological community living in porous rock deep beneath the seafloor. The microbes in this hidden world appear to be an important source of dissolved organic matter in deep ocean water, a finding that could dramatically change ideas about the ocean carbon cycle. Matthew McCarthy, associate professor of ocean sciences at the University of California, Santa Cruz, led a team of researchers from several institutions who analyzed the...

Pompeii Worm, Alvinella pompejana
2014-01-12 00:00:00

The Pompeii worm (Alvinella pompejana) is a species of polychaete worm, or bristle worm that is only found in the Pacific Ocean. It resides at hydrothermal vents, making it an extremophile, and was first discovered French marine biologists of the coat of the Galapagos Islands in the 1980s. It was described by Lucien Laubier and Daniel Desbruyeres as a deep-sea polychaete that could withstand extreme amounts of heat. The Pompeii worm can reach an average length of up to five inches and is...

Bathymodiolus Thermophilus
2013-04-16 18:50:25

Bathymodiolus thermophilus is a species of large, deepwater mussel, a marine bivalve mollusk belonging to the family Mytilidae. The species was discovered at abyssal depths when submersible vehicles began exploring the deep ocean. It occurs on the sea bed, frequently in large numbers, close to hydrothermal vents where hot, sulphur-rich water wells up through the floor of the Pacific Ocean. This is a very large mussel with a dark brown periostracum, growing to a length of about 8 inches....
