The penultimate glaciation (marine isotope stage (MIS) 6) is considered regionally extreme compared to the last glacial maximum, in which European ice sheets had a vast areal extent. In contrast deglaciation (19–7 ka), (140–130 ka) hosts one of most rapid oceanographic changes late Pleistocene. this study, we reconstructed near-surface and thermocline central northeast Atlantic by analyzing sed...

Through the dynamical coupling between ocean and atmosphere, the vertical advection of anomalous subsurface temperature by the mean upwelling and the zonal advection of mean sea surface temperature (SST) by anomalous current constitute the so-called the thermocline and zonal advective feedbacks that are essential for El Nifio / Southern Oscillation (ENSO) coupled dynamics. In this paper, we dem...

[1] We analyze the temperature anomaly of the Pinatubo eruption using an exact mathematical solution of a standard energy balance model that includes coupling between the mixed layer and the thermocline. Our solution yields a short response time t = 4.4 months and a small climate sensitivity l = 0.22 C/(W/m), implying short-term negative feedback. Also, our analysis determines a value of the ef...

Strong diurnal oscillations, documented by temperature data that were collected along a submarine cliff on the Lastovo Island (southern Adriatic), are studied and compared with sea level and wind measurements at Dubrovnik and Komiža (island of Vis). Three thermistors were deployed at the depths of 15, 22 and 36 m between March 2001 and March 2002. Pronounced diurnal temperature oscillations wer...

Observations near a large tabular iceberg in theWeddell Sea inMarch and April 2009 show evidence that water from ice melting below the surface is dispersed in two distinct ways. Warm, salty anomalies in T–S diagrams suggest that water from the permanent thermocline is transported vertically as a result of turbulent entrainment of meltwater at the iceberg’s base. Stepped profiles of temperature,...

Abstract We investigated the relationship between North Atlantic Oscillation (NAO) and Indian Ocean Dipole (IOD), which has remained unknown to date. Reanalysis data linear baroclinic model experiments were employed in our study. The results showed significant correlation March NAO boreal summer autumn IOD, independent of El Niño–Southern signal, verified by partial analysis. Air–sea interactio...

Pacific Ocean oceanic heat transport is studied in an ocean model coupled to an atmospheric mixed-layer model. The shallow meridional overturning circulation cells in the Tropics and subtropics transport heat away from the equator. The heat transport by the horizontal gyre circulation in the Tropics is smaller and directed toward the equator. The response of the Pacific oceanic heat transport t...

The Solomon Sea is a key region of the southwest Pacific Ocean, connecting the thermocline subtropics to the equator via western boundary currents (WBCs).Modifications to watermasses are thought to occur in this region because of the significant mixing induced by internal tides, eddies, and the WBCs. Despite their potential influence on the equatorial Pacific thermocline temperature and salinit...

large amounts of degradable wastes including sewage water and agricultural waste or nutrients that stimulate growth of organic matter are discharged into the caspian sea. as a result, average dissolved oxygen concentration in deeper layers is decreasing. this paper presents distribution and seasonal variations of the concentration of dissolved oxygen over the southern shelf of the caspian sea a...

New estimates are obtained of oxygen utilization rates on isopycnal surfaces in the North Atlantic subtropical gyre thermocline based on tritium inventories (2.4-3.5 mol m -2 yr -1) and 228Ra measurements (8.5 _+ 0.8 mol m -2 yr-l). Arguments are given for why the tritium inventory oxygen utilization rate estimate may be too low. The 228Ra results are combined with recent estimates of oxygen ut...
