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....
Intensity of desert storms may affect ocean phytoplankton
desert storms ocean phytoplankton
2015/9/8
Each spring, powerful dust storms in the deserts of Mongolia and northern China send thick clouds of particles into the atmosphere. Eastward winds sweep these particles as far as the Pacific, where du...
Lab experiments question popular measure of ancient ocean temperatures
Lab question popular ancient ocean temperatures
2015/9/9
Understanding the planet’s history is crucial if we are to predict its future. While some records are preserved in ice cores or tree rings, other records of the climate’s ancient past are buried deep ...
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...
Fisheries,El Niño-Southern Oscillation and Upper Ocean Temperature Records:An Eastern Pacific Example
Fisheries El Nino-Southern Oscillation Upper Ocean Temperature Records Eastern Pacific Example
2015/8/19
It is often recounted that the collapse of the Peruvian anchoveta fishery in the early 1970s was a direct consequence of the El Niño of 1972–73. Comparison of time series of upper-ocean thermal d...
Deep Convective Plumes in the Ocean
The mesoscale ocean circulation deep convection the atmosphere
2015/8/17
Deep convection is a process in which the mesoscale ocean circulation and atmospheric forcing work together to weaken the ambient stratification and to cause surface waters to sink to great depths wit...
Understanding how climate varies in time is a central issue of climate research. Of particular interest are climate variations which occur within the human lifespan, say over 5- to 100-y time scales. ...
Grazing and Zooplankton Production as Key Controls of Phytoplankton Production in the Open Ocean
Coast phytoplankton pigment waters physical oceanography
2015/8/17
Thanks to NASA's Coastal Zone Color Scanner (CZCS, 1978-1986), nearly ocean-wide coverage of the distribution of phytoplankton pigment in the upper part of the euphotic zone and, in effect, in the mix...
1,800 Years of Global Ocean Cooling Halted by Global Warming
1,800 Years Global Ocean Cooling Halted Global Warming
2015/9/9
Prior to the advent of human-caused global warming in the 19th century, the surface layer of Earth’s oceans had undergone 1,800 years of a steady cooling trend, according to a new study. Dur...
