Two idealized, three-dimensional, analytical models of mid-depth meridional overturning in a basin with a southern-hemisphere circumpolar connection are described. In the first, the overturning circulation can be understood as a ‘pump and valve’ system, in which the wind forcing at the latitudes of the circumpolar connection is the pump, and surface thermodynamic exchange at high northern latit...

The stratification of the equatorial thermocline is a key variable for tropical climate dynamics, through its influence on the temperature of the water that upwells in the eastern equatorial ocean. In this study, two types of ocean models are used, an ocean general circulation model (GCM) and a 11⁄2-layer model, to investigate processes by which changes in the midlatitude winds affect the equat...

Disentangling the role of factors responsible for juvenile fish dispersal is essential to understand ecology individual species, setting corresponding conservation status and evaluating potential risk in case invasion. Because their small body size high sensitivity environmental conditions, movements have largely been explained by external such as wind-induced water currents. In this study, ear...

[1] Seasonal to interannual variability of the Lombok Strait surface layer transport is investigated. The geostrophic transport within the surface layer is estimated from the cross-channel pressure gradient measured by a pair of shallow pressure gauges positioned on opposing sides of Lombok Strait during 1996-1999. The Ekman transport through Lombok Strait, derived from scatterometer winds, is ...

[1] The velocity and transport, with thermohaline properties, are determined from simultaneous moored time series within Mindoro, Tablas and Panay Straits that connect the South China Sea (SCS) and Sibuyan Sea to the Sulu Sea. These passages provide the only pathway for the SCS throughflow below thermocline depths and play a critical role in regulating the heat and freshwater balance within the...

Acoustic techniques have been proposed as a new tool to assess jellyfish populations. However, the presence of mixed echoes from jellyfish and other organisms that share their distribution often prevent accurate estimates of their abundance and distribution being obtained. The isolated population of Aurelia inhabiting the Veliko Jezero (Big Lake-BL) of Mljet Island, in the South Adriatic Sea, o...

[1] A suite of satellite and in-situ observations are used to study ocean-atmospheric conditions over the tropical Southwest Indian Ocean (SWIO) during 2006–2007 when ElNino and an IndianOcean dipole took place simultaneously. Argo profiles reveal a pronounced up-westward propagation of subsurface warming in the southern tropical Indian Ocean associated with Rossby waves traveling on the slopin...

Vertical displacement of the thermocline may be due either to a convergence or a divergence of Ekman transport in the surface layer. Data from ships of opportunity between New Caledonia an¿ Japan are used to compute the wind stress curl, from 1973 to 1980, neglecting the zonal gradients. The pattern is compared to the changes of the 25OC isotherm depth between 5ON\ and 20°S from all data availa...
