Upper mantle structure beneath the eastern Pacific Ocean ridges

[1] We analyze vertical component body and surface waves for 10 Mw > 5 earthquakes, recorded by ocean bottom seismometers at regional and teleseismic distances. Through waveform modeling, we place new constraints on along-axis variation in temperature and partial melt beneath the eastern Pacific ridges. The resulting best fit models show over 9% variation in average lithosphere shear velocities...

Decadal trends of the upper ocean salinity in the tropical Indo-Pacific since mid-1990s

A contrasting trend pattern of sea surface salinity (SSS) between the western tropical Pacific (WTP) and the southeastern tropical Indian Ocean (SETIO) is observed during 2004-2013, with significant salinity increase in the WTP and freshening in the SETIO. In this study, we show that increased precipitation around the Maritime Continent (MC), decreased precipitation in the western-central tropi...

A Near-Annual Pacific Ocean Basin Mode

Some fairly regular and nearly annual variability in the equatorial Pacific after the major 1997/98 El Niño event is studied. Sea level, sea surface temperature (SST), and surface wind anomalies of this variability are tied together in a way similar to the slow cycles of El Niño–Southern Oscillations (ENSO). Despite a slightly longer-than-annual time scale, similar variability was also found in...
