Über dieses Buch

This book presents maps of Antarctica, exploring various aspects of its disturbing geopotential and based on the EIGEN 6C4 model, arguably the best gravitational field model currently available. It also provides the latest data on Antarctica’s bedrock topography according to Bedmap 2. In an extensive series of segment maps the book highlights (i) a gravity anomaly (disturbance), (ii) the Marussi tensor of the second derivatives of the disturbing geopotential, (iii) invariants and their ratios, (iv) the strike angle, and (v) virtual deformations.

Due to their various degrees of sensitivity to the density contrasts of causative bodies under the Earth’s surface, these maps provide many details that have a range of potential geo-applications. They guide the reader through the entire continent, in segments divided by 30 degrees of longitude, and through geodetic latitudes of between 60 and 90 degrees south. Each segment is complemented by detailed zoom-in maps for selected localities of special interest.

Chapter 1. Introduction

A motif to write this Atlas is described. The world priority of our Atlas (2017) is in the use of a full set of the gravity aspects (not only the traditional gravity anomalies) together with the newest data combining the best now available global gravity field model and bedrock topography model valid for Antarctica.

Chapter 2. Theory

A short outline of the theory is given with the definitions and examples explaining the meaning of the gravity aspects. We show (by a simple model) a different sensitivity of the gravity aspects to the depth of the causative body (density anomaly responsible for the gravity signal) by Fig. 2. 1. and define the geocentric and geodetic latitudes.

Chapter 3. Data

Data inputs are described in these sections; first the global gravity field model EIGEN 6C4 (and the role of the gradiometry data from GOCE in it), then the bed topography under the ice cover in the Bedmap 2 model, and then their combination in the spherical harmonic expansion SatGravRET14 (the actually used model to compute the gravity aspects in this Atlas). We note about the polar gap in the data, data resolution, and about other data sources. Finally we provide a practical guide to the figures in this Atlas.

Chapter 4. Antarctica—A General Look

“General views” over the whole Antarctica are presented in this section. The details follow in the segments and zooms in the next chapter.
Jaroslav Klokočník, Jan Kostelecký, Aleš Bezděk

Chapter 5. Segments and Selected Details

This is the core of our Atlas: the figures of the gravity aspects according to RET 14 and the bedrock topography from Bedmap 2.

Systemische Notwendigkeit zur Weiterentwicklung von Hybridnetzen

Die Entwicklung des mitteleuropäischen Energiesystems und insbesondere die Weiterentwicklung der Energieinfrastruktur sind konfrontiert mit einer stetig steigenden Diversität an Herausforderungen, aber auch mit einer zunehmenden Komplexität in den Lösungsoptionen. Vor diesem Hintergrund steht die Weiterentwicklung von Hybridnetzen symbolisch für das ganze sich in einer Umbruchsphase befindliche Energiesystem: denn der Notwendigkeit einer Schaffung und Bildung der Hybridnetze aus systemischer und volkswirtschaftlicher Perspektive steht sozusagen eine Komplexitätsfalle gegenüber, mit der die Branche in der Vergangenheit in dieser Intensität nicht konfrontiert war. Jetzt gratis downloaden!
