The shell ?18O of young modern Aequipecten opercularis from the southern North Sea provides an essentially faithful record seasonal variation in seafloor temperature. In this well-mixed setting, A. also serves as a proxy for surface Individuals less agitated (e.g. deeper) settings warm climate would not be expected to full range temperature because thermal stratification summer. Such circumstan...

The Indian Ocean has sustained robust surface warming in recent decades, but the role of multidecadal variability remains unclear. Using ocean model hindcasts, characteristics of low-frequency Indian Ocean temperature variations are explored. Simulated upper-ocean temperature changes across the IndianOcean in the hindcast are consistent with those recorded in observational products and ocean re...

The output from a coupled general circulationmodel (CGCM) is used to develop evidence showing that the tropical Pacific decadal oscillation can be driven by an interaction between the El Niño–Southern Oscillation (ENSO) and the slowly varyingmean background climate state. The analysis verifies that the decadal changes in themean states are attributed largely to decadal changes in ENSO statistic...

Basin-scale variations in oceanic physical variables are thought to organize patterns of biological response across the Pacific Ocean over decadal time scales. Different physical mechanisms can be responsible for the diverse basin-scale patterns of sea-surface temperature (SST), mixed-layer depth, thermocline depth, and horizontal currents, although they are linked in various ways. In light of ...

Abstract The interdecadal Pacific oscillation (IPO) and Atlantic multidecadal (AMO), two leading modes of decadal climate variability, are not independent. It was proposed that ENSO-like sea surface temperature (SST) variations play a central role in the responses to AMO forcing. However, observational analyses indicate AMO-related SST anomalies tropical far weaker than those extratropical Nort...

The shipboard measurements over approximately 55 years in the southwestern part of East Sea (Sea Japan) demonstrate a remarkable basin-wide, interannual-interdecadal variability temperature-based thickness Intermediate Water (ESIW) whose temporal shows strong correlation with density-based (r = 0.97). Relevant to long-term ESIW thickness, clear changes horizonal and vertical features have been ...
