Scientists determine early Earth was a ‘water world’ by studying exposed ocean crust（图）
Scientists early Earth water world’ exposed ocean crust
2020/3/13
The Earth of 3.2 billion years ago was a "water world" of submerged continents, geologists say, after analyzing oxygen isotope data from ancient ocean crust now exposed on land in Australia. The findi...
Slow earthquakes in ocean subduction zones shed light on tsunami risk
Slow earthquakes ocean subduction zones tsunami risk
2017/7/21
Understanding "slow-slip" earthquakes on the seafloor -- seismic events that occur over a period of days or weeks -- is giving researchers new insights into undersea earthquakes and the subsequent cre...
The lunar magma ocean volatile signature recorded in chlorine-rich glasses in KREEP basalts 15382 and 15386
chlorine fluorine Moon water glass
2017/4/10
The last liquids of the lunar magma ocean, known as urKREEP, should be highly enriched in volatiles, such as water,
fluorine, and chlorine. We find chlorine-rich glasses in two pristine KREEP basalts...
A 1000-year simulation with the IPSL ocean-atmosphere coupled model
coupled climate model long-termclimate simulation oceanic overturning circulation model drift
2015/9/17
A 1000-year climate simulation is run with the ocean-atmosphere coupled model developed at the Institute Pierre-Simon Laplace (IPSL, Paris). No flux adjustment is used. The drift of the model is analy...
Variability of Atlantic Ocean heat transport and its effects on the atmosphere
climate variability North Atlantic Oscillation (NAO) Ocean Heat Transport (OHT) Sea Surface Temperature (SST) ThermohalineCirculation (THC)
2015/9/17
The variability of the Atlantic meridional Ocean Heat Transport (OHT) has been diagnosed from a simulation of a coupled ocean-atmosphere general circulation model, and the mechanisms responsible for t...
The monterey bay broadband ocean bottom seismic observatory
seismic station San Gregorio Fault earthquake
2015/9/7
We report on the installation of a long-term buried ocean-floor broadband seismic station
(MOBB) in Monterey Bay, California (USA), 40km off-shore, at a water depth of 1000 m.
The station was instal...

The ocean sciences are beginning a new phase in which scientists will enter the ocean environment and adaptively
observe the Earth-Ocean system through remote control of sensors and sensor platforms....
Reappraisal of effective elastic thickness in the south-west Indian Ocean, and its possible implications
Mid oceanic ridge Effective elastic thickness Hotspot
2015/8/24
The bathymetry of the south-west Indian Ocean is dominated by three mid-oceanic ridge systems: the Chagos–Laccadives Ridge, the Central Indian Ridge, and the Mascarene Plateau. Although there have bee...
This volume is the seventy fifth in the Antarctic Research Series published since 1963 by the American Geophysical Union. This volume is a 380-page collection of twenty peer-reviewed papers focused mo...

Seismic structure the lithosphere and upper mantle beneath ocean islands near mid-oceanic ridges
2015/1/6
Deciphering the seismic character of the young lithosphere near mid-oceanic ridges (MORs) is a challenging endeavor. In this study, we determine the seismic structure of the oceanic plate near the MOR...
