The Tarfaya-Agadir Basin in offshore Morocco is a frontier exploration area with no deepwater industry well penetrations and limited well control in the updip shelfal equivalent. Recent detailed 3D seismic mapping and study by Shell has identified the presence of two large mass transport complexes (MTCs) in the Tertiary interval, in addition to a number of smaller and younger MTCs. The large MTCs, named Tejas A and Tejas B, exhibit distinct seismic characteristics that may be significant to understanding the evolution of the basin during the Tertiary. The basal Tejas A is characterized by numerous kilometerscale, coherent transported blocks. The size and quantity of transported blocks observed in Tejas A is unique in Morocco and the Atlantic Margin. The MTC in the younger Tejas B is a thick chaotic unit with distinctive downdip erosional lobes. This deposit is overlain by high amplitude, parallel seismic facies. The chaotic seismic facies is often sharp-edged, with well-defined pressure ridges. Only a few small transported blocks and erosional remnants have been observed in Tejas B. Failure deposits account for a significant percentage of the Tertiary stratigraphic interval in the 3D survey area.

Total‐intensity aeromagnetic surveys of the Aleutian Marshall, and Bermuda Islands were completed in 1948. The anomalies associated with the Aleutian volcanoes are attributed mainly to topographic relief and are not an indication of the degree of volcanic activity. Eniwetok presents a magnetic pattern that would be produced by an irregular‐shaped rimmed depression in the basement, modified by the two adjoining seamounts, and differs from Bikini, whose magnetic features would be produced by a broad seamount with irregular surface relief. The Bermuda survey demonstrated magnetic features typical of volcanic rocks. Comparison of an observed and a theoretical profile computed by Press and Ewing indicates that their assumptions are reasonably correct. The Aleutian Trench survey shows anomalies that are attributed to susceptibility contrasts but none that can be correlated with the trench. A traverse from Adak, Aleutian Islands, to Kwajalein, Marshall Islands, exhibited several large anomalies that are presumed to be caused by susceptibility contrasts but may be indications of uncharted seamounts. Two traverses, one from Cape May, N.J., to Bermuda and the other from Bermuda to Long Island, N.Y., reveal a change in the magnetic field approximately 300 miles from the Atlantic Coast that indicates a possible thinning of the sial and an exposure of sima.

Abstract:This paper addresses the calibration of mobile mapping systems and the feasibility of using a total station as a sensor for indoor mobile mapping systems. For this purpose, the measuring system of HafenCity University in Hamburg is presented and discussed. In the second part of the calibration, the entire system will be described regarding the interaction of laser scanners and other parts of the system. Finally, the preliminary analysis of the use of a total station is presented in conjunction with the measurement system. The difficulty of time synchronization is also discussed. In multiple tests, a comparison was made versus a reference solution based on GNSS. Additionally, the suitability of the total station was also considered for indoor applications.

There are a number of consumer electronics applications on the market that use the Global Navigation Satellite System (GNSS). Smartphones equipped with GNSS are used for navigation. In surveying, GNSS-based mobile mapping systems (MMS) are used daily to capture the local environment in three dimensions. In recent years, research into indoor applications has increased, particularly the mapping of building interiors using kinematic measurement methods and navigation indoors. A significant problem is the loss of GNSS-based positioning information. This problem could be eliminated using an Inertial Measurement Unit and/or a combination of additional information. HafenCity University (HCU) is engaged in the development of a modular mobile mapping platform, known as a mobile mapping system (MMS), that can also be used indoors. Furthermore, HCU is working on algorithms for indoor navigation that use commercially available smartphones, thus obviating costly infrastructure. Base maps are important for visual reference and can be used to provide supporting information in navigation algorithms, but constructing base maps is often problematic. The MMS is used for creating maps for indoor navigation. In this paper, a concept of the interaction of the two research areas is presented, and insight on the states of both research areas is given.
