A system of meridional ridges in the western South Pacific Ocean frame the Lau Basin and Havre Trough, and form a barrier to direct communication between the far western South Pacific basins and the interior South Pacific Ocean. The eastern side of this system comprises the Tonga and
Kermadec Ridges, the location of the main deep western boundary current entering the Pacific Ocean. Observations from floats released in the Lau Basin as part of the RIDGE2000 program suggested the presence of a western boundary current along the Lau Ridge exiting into the North Fiji Basin.
Those observations, together with Argo sub-surface float data and repeat hydrographic sections, confirm and expand the boundary current observations along the Lau Ridge throughout the Lau Basin and into the Havre Trough, along the Colville Ridge. The observations also reveal two previously
unrecognized westward flowing jets bisecting the Lau Basin and Havre Trough. Using an extension to the classic Stommel-Arons abyssal circulation model, the predicted strength and location of these boundary currents and their bifurcation is compared with the float observations. The model provides
a simplified view of the dynamics controlling the boundary current structure in the deep basins. A comparison of transport within the western boundary current derived from float data, hydrographic sections, and the idealized analytical model indicates that roughly 4 Sv (below 1,000 db) is
transported northward through the Lau Basin, exiting into the North Fiji Basin.

In November 1806, the damaged Port-au-Prince arrived at what Captain Cook had called the Friendly Islands. William Charles Mariner (1791–1853) was among the few crew members spared by the native inhabitants. He lived there for four years. Published in 1818, this two-volume second edition offers an important early insight into Tongan customs and language. As editor John Martin (1789–1869) explains, the structure of a nation's language is vital to the consideration of its history. So successful was the first edition of 1817 - expanded upon here to include 'generally corroborative, and in a few instances somewhat corrective' information from another erstwhile inhabitant - that within months of its publication a French translation appeared; German and American editions soon followed. Volume 2 covers diverse aspects of Tongan society, from its music to notions of the soul, and includes a detailed grammar of the language and 2,000 words of vocabulary
