Autonomous Lagrangian Circulation Explorer (ALACE) floats are used to examine mean flow and eddy fluxes at 900-m depth in the Southern Ocean. Mean temperature and dynamic topography from float data are consistent with earlier estimates from hydrographic surveys, although floats imply warmer temperatures and narrower frontal structures than do atlas data. Differences between hydrographic and ALA...

Abstract Electronic navigational charts (ENCs) are specialised geospatial datasets, issued by or on the authority of a government hydrographic office, in accordance with International Hydrographic Organisation's (IHO) standards, specifications and symbol sets. The datasets generally comprise encoded information collected from surveys, aimed primarily at safety navigation. Most ENCs not openly a...

abstract area-reduction method is one of the most common experimental methods that determines the sediment distribution in reservoirs. in this method, reservoirs are geometrically divided into four types. for all reservoir types, parameters are achieved based on a limited number of reservoirs which leads to large scale errors for prediction of this method. so suitable parameters can be achieved...

A new transindian hydrographic section across 32 degrees S reveals that thermocline mode waters have become saltier and colder since 1987. This change almost entirely reverses the observed freshening of mode waters from the 1960s to 1987 that has been interpreted to be the result of anthropogenic climate change on the basis of coupled climate models. Here, we compare five hydrographic sections ...

A hydrographic data set was collected in winter 1997 as part of the “Deep Convection” Accelerated Research Initiative (ARI). These data — together with atmospheric forcing fields (K. Moore, University of Toronto) and hydrography collected the previous fall and following spring (A. Clarke, Bedford Institute of Oceanography) — are being analyzed together to investigate overturning in the Labrador...

Nano-microplankton biomass, mesozooplankton biomass and hydrographic features were measured with mesoscale spatial resolution during 3 surveys in the Bay of Biscay between March and June 2004. Regions of high plankton biomass were associated with mesoscale physical structures. Generalized additive models (GAMs) based upon surface salinity, surface temperature and stratification of the water col...

The present research work is dedicated to the opening of the data pool of hydrographic measurement networks to exchange information compliant to legal requirements (INSPIRE Directive, Water Framework Directive) based on standardized interfaces (OGC Sensor Observation Service – SOS) as well as their quality assurance. The prototype to validate our approach makes it possible to send requests by u...
