It is well recognized that the time series of hydrologic variables, such as rainfall and streamflow are significantly influenced by various large-scale atmospheric circulation patterns. The influence of El Niño-southern oscillation (ENSO) on hydrologic variables, through hydroclimatic teleconnection, is recognized throughout the world. Indian summer monsoon rainfall (ISMR) has been proved to be...

The present study investigates the genetic diversity of Scarus ghobban, a recently introduced parrotfish in the Mediterranean Sea via the Suez Canal. Two mitochondrial and one nuclear DNA regions were sequenced and phylogenetic relationships investigated, from samples collected from Lebanon and across its natural range. Scarus ghobban clustered in two major clades, Pacific Ocean and Indian Ocea...

iran is located in arid and semiarid areas based on continental divisions; any change in precipitation would have potential effects on agriculture, economic and other related issues in general. therefore, it is of high importance to know and identify the moisture-related sources needed to study the country’s precipitation data. for this purpose, it is important to correlate monthly precipitatio...

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 ...

In the last years, cases of chikungunya fever have been reported in international travellers returning from the Indian Ocean region. The cases have been linked to the re-emergence of chikungunya fever on Indian Ocean islands in 2006. We describe the first case of chikungunya fever in a French traveller returning from Male, an island of the Maldives islands, confirming the permanence of virus ci...

We examined the population structure of the black tiger prawn, Penaeus monodon Fabricius, 1798, in the Indo-West Paci®c by analyzing the geographic distribution of elongation factor 1-alpha intron sequences from specimens collected during the winter and spring of 1997. Both the molecular phylogeny of alleles and F-statistics indicated very strong di€erentiation between populations from the west...

The devastating 2004 Indian Ocean tsunami caught millions of coastal residents and the scientific community off-guard. Subsequent research in the Indian Ocean basin has identified prehistoric tsunamis, but the timing and recurrence intervals of such events are uncertain. Here we present an extraordinary 7,400 year stratigraphic sequence of prehistoric tsunami deposits from a coastal cave in Ace...

Atmospheric deposition is an important but still poorly constrained source of trace micronutrients to the open ocean because of the dearth of in situ measurements of total deposition (i.e., wet +dry deposition) in remote regions. In this work, we discuss the upper ocean distribution of dissolved Fe and Al in the eastern Indian Ocean along a 95°E meridional transect spanning the Antarctic margin...

During the CINDY/DYNAMO field campaign (fall/winter 2011), intensive measurements of the upper ocean, including an array of several surface moorings and ship observations for the area around 75°E–80°E, Equator-10°S, were conducted. In this study, large-scale upper ocean variations surrounding the intensive array during the field campaign are described based on the analysis of satellite-derived ...
