A fleet of baited remote underwater video stations was set in lagoonal and inter-reef waters of the Great Barrier Reef Marine Park, across 14° of latitude and the entire shelf. Counts of the maximum number seen in any one field of view were used to estimate relative abundance of 347 species of bony fishes, cartilaginous fishes and sea snakes. Boosted regression trees were used to assess the inf...

The Ellenburger Group of the West Texas Permian Basin is part of a Lower Ordovician carbonate platform sequence that covers a large area of the United States. During the Early Ordovician, the Permian Basin area was located on the southwest edge of the Laurentia plate between 20° and 30° latitude. The equator crossed northern Canada, situating Texas in a tropical to subtropical latitude. The are...

[1] We investigate the effect of self-attraction and loading (SAL) induced by the projected accumulation of sea water on shallow continental shelf areas. Using output from a climate model, we compute 21st century changes in regional steric sea surface height and find that steric changes are largest over the deep ocean and relatively small on the shallow continental shelves. The resulting redist...

Massive amounts of anthropogenic radiocaesium Cs that were released into the environment by the Fukushima Daiichi Nuclear Power Plant accident in March 2011 are widely known to have extensively migrated to Pacific Ocean sediment off of eastern Japan. Several recent reports have stated that the sedimentary Cs is now stable with a remarkably heterogeneous distribution. The present study elucidate...

a stratigraphic section from the tirgan formation was selected in arkan village nearby bojnourd city in order to study echinoderm fauna systematically. many specimens of echinoderms, especially toxasteridae which is associated with brachiopods were collected and studied systematically in this paper. microscopie slides were also prepared and studied. all slides contain benthic foraminifers and c...

Idealized laboratory experiments reveal the existence of forced dissipative hybrid Rossby shelf modes. The laboratory ocean consists of a deeper ocean, accommodating basin scale Rossby modes, and a coastal step shelf, accommodating trapped shelf modes. Planetary Rossby modes are mimicked in the laboratory via a uniform topographic slope in the North-South direction. Hybrid modes are found as li...

Received 15 January 2001; revised 30 October 2001; accepted 15 November 2001; published 2 July 2002. [1] Methane in surface waters and marine air off Oregon (44 240N–44 540N, 124 360W–125 240W) was continuously surveyed in July 1999. During a high-resolution survey after a period of steady win ds from the north, CH4 concentrations were high in the northeastern region, near the shelf edge. The h...
