Estimated Global Hydrographic Variability

An estimate is made of the three-dimensional global oceanic temperature and salinity variability, omitting the seasonal cycle, both as a major descriptive element of the ocean circulation and for use in the error estimates of state estimation. Historical hydrography, recent data from the World Ocean Circulation Experiment, and Argo profile data are all used. Root-mean-square vertical displaceme...

Huddl: the Hydrographic Universal Data Description Language

Resumen Since many of the attempts to introduce a universal hydrographic data format have failed or have been only partially successful, a different approach is proposed. Our solution is the Hydrographic Universal Data Description Language (HUDDL), a descriptive XML-based language that permits the creation of a standardized description of (past, present, and future) data formats, and allows for...

A Data Capture System for Hydrographic Maps

The main part of the thesis is five separate research papers published in or submitted to leading journals in the field of computer vision and pattern recognition. In addition, a data capture system for hydrographic maps has been designed and implemented. It places the results of the thesis papers in context and demonstrate their importance. The five thesis papers are [1] Øivind Due Trier and T...
