Whole-Genome Positive Selection and Habitat-Driven Evolution in a Shallow and a Deep-Sea Urchin
positive selection dN/dS
2015/12/11
Comparisons of genomic sequence between divergent species can provide insight into the action of natural
selection across many distinct classes of proteins. Here, we examine the extent of positive se...

hydrophones Bragg fiber-laser pressure sensors
2015/9/8
The present paper will discuss the work in progress at the Department of Physics of the University of Pisa in collaboration
with the IFAC laboratory of CNR in Florence to develop pressure sensors wit...
Underwater Laboratories for Astroparticle Physics and Deep Sea Science
Neutrinos underwater laboratories
2015/9/7
The exploration of deep sea environments is presently at the dawn of a new era:
underwater laboratories, permanently installed on the sea floor and offering
power and on-line data transmission links...
Deep Sea Gravity Measurements: GEOSTAR-2 Mission Results
seafloor gravimeter teleseismic waves
2015/9/7
A new concept gravity meter with sensitivity close to Hz ms / 10 2 8 ? ? in the range of 10 -5 ?1Hz intended for observation of the vertical component of the Earth gravity and
teleseismic waves was i...
Deep-sea borehole seismological observatories in the western Pacific: temporal variation of seismic noise level and event detection
deep-sea borehole observatory broadband seismometer seismic noise level
2015/9/7
Seismological networks provide critical data for better understanding the dynamics of the Earth; however, a great limitation on existing networks is the uneven distribution of stations. In order to ac...
International Law:Implications for Exploitation of Deep-Sea Benthic Biodiversity
International Law Deep-Sea Benthic Biodiversity
2015/8/13
There is increasing interest in the profusion of living resources dwelling on and in the ocean floor, from scientific interest in what is there and why life is so diverse, to interest in the potential...
HAUSGARTEN: Multidisciplinary Investigations at a Deep-Sea, Long-Term Observatory in the Arctic Ocean
Multidisciplinary Investigations Deep-Sea
2015/7/30
The marine Arctic has played an essential role in the history of our planet over the past 130 million years and contributes considerably to the present functioning of Earth and its life. The global cy...
As oceanographers contemplate a renewed commitment to ocean exploration (National Research Council, 2003), Helen Rozwadowski has given us a book chronicling the importance of discovery and exploration...
The year 1967 was spent preparing for Leg 1 of the Deep Sea Drilling Project (DSDP). Because it was believed that graduate students, instead of professors, would staff the continuous expeditions, I jo...
Exploration for Deep-Sea Corals on North Pacific Seamounts and Islands
North Pacific Seamounts Islands
2015/7/22
Seamounts are mountains that rise from the seafloor. The technical geological definition of a seamount is a steep-sided feature with greater than 1000 m of relief compared to the surrounding sea botto...
Little is known of New Guinea’s deep benthic communities. In
fall 2010, the Muséum national d’Histoire naturelle, Institut de Recherche pour le
Développement, and University of Papua New ...
Volcanic eruptions are important events in Earth's cycle of magma generation and crustal construction. Over durations of hours to years, eruptions produce new deposits of lava and/or fragmentary eject...
Chemoautotrophy at Deep-Sea Vents:Past,Present,and Future
Deep-Sea Vents Past Present Future
2015/7/14
Chemolithoautotrophic microorganisms are at the nexus of hydrothermal systems by effectively transferring the energy from the geothermal source to the higher trophic levels. While the validity of this...
A 180-Million-Year Record of Sea Level and Ice Volume Variations from Continental Margin and Deep-Sea Isotopic Records
