During the last deglaciation, atmospheric carbon dioxide concentrations rose at the same time that the 114C of that CO2 fell. This has been attributed to the release of 14C-depleted carbon dioxide from the deep ocean1, possibly vented through the Southern Ocean2–5. Recently, a sediment record from the eastern North Pacific Ocean spanning the last deglaciation was interpreted to reflect transpor...

Theories of late Cenozoic climate cooling assume that central Asian aridification and high dust accumulation rates in the Chinese Loess Plateau and the North Pacific Ocean are genetically related. On the basis of detailed sediment provenance analysis, we show that high dust accumulation rates in the Chinese Loess Plateau and the North Pacific Ocean during the late Miocene-Pliocene were mainly c...

An atmospheric general circulation model (AGCM) is used to examine the role of Indian Ocean sea surface temperature (SST) anomalies in regional climate variability. In particular, the authors focus on the effect of the basinwide warming that occurs during December through May after the mature phase of El Niño. To elucidate the relative importance of local and remote forcing, model solutions wer...

The central Pacific Ocean with its many low lying islands and atolls is under threat from sea level rise and increased storm activity. Here, we illustrate how increasing frequency and severity of large scale storm events associated with global climate change may be particularly profound at the local scale for human populations that rely on lagoon systems for provision of a variety of goods and ...

The surgeonfish Ctenochaetus striatus is abundant and widely distributed on reefs throughout the Indian and Pacific Oceans. Population samples at 15 sites that spanned 158° of longitude and 40° of latitude across both hemispheres of the Indian and Pacific oceans allowed us to examine geographic variation in longevity, growth rate and adult size of this species. Samples from 5 sites in the India...

The Indonesian Throughflow (ITF) is an important component of the upper cell of the global overturning circulation that provides a low-latitude pathway for warm, fresh waters from the Pacific to enter the Indian Ocean. Variability and changes of the ITF have significant impacts on Indo-Pacific oceanography and global climate. In this paper, the observed features of the ITF and its interannual t...

The sparsity of data in the southwest Pacific Ocean has limited our understanding of the effect of oceanography in regional ocean climate, and on the role that the ocean plays in ocean-atmosphere interaction. Consequently, comprehensive climate studies of the southwest Pacific region have been constrained due in part to this relatively poor spatial (on regional to large scales) and temporal (on...

Bigeye (Thunnus obesus) is a large, pelagic, and migratory species of tuna that inhabits tropical and temperate marine waters worldwide. Previous studies based on mitochondrial RFLP data have shown that bigeye tunas from the Atlantic Ocean are the most interesting from a genetic point of view. Two highly divergent mitochondrial haplotype clades (I and II) coexist in the Atlantic Ocean. One is a...

A numerical model for the global tsunamis computation constructed by KOWALIK et al. (2005), is applied to the tsunami of 26 December, 2004 in the World Ocean from 80 S to 69 N with spatial resolution of one minute. Because the computational domain includes close to 200 million grid points, a parallel version of the code was developed and run on a Cray X1 supercomputer. An energy flux function i...

The most striking feature of the Asian-Australian monsoon associated with the El Niño teleconnection is the evolution of anomalous anticyclones over the western North Pacific (WNP) and southeast Indian Ocean (SIO). In this study we investigated the relative role of remote and local SST forcing in shaping the monsoon anomalies with an atmospheric general circulation model (AGCM). Four idealized ...
