Aeroplane design study STOL airliner (A71). Part 1- configuration description and data [PDF]
, 1972 The interest in STOL airliners was reflected in the choice of a 100-118 passenger short range aircraft of this type as the 1971 design project. In addition to the use of the study for detailed investigation by the students of Aircraft Design it also ...

Bio‐mediated cementation of supratidal beach sediments associated with groundwater springs
Sedimentology, EarlyView.ABSTRACT The formation of beachrock, sensu stricto, via carbonate precipitation in the intertidal zone is widespread throughout the tropics and subtropics. While cementation of supratidal beach sediments has also been noted in several locations, it has received much less attention.

A procedure for developing an acceptance test for airborne bathymetric lidar data application to NOAA charts in shallow waters [PDF]
, 2013 National Oceanic and Atmospheric Administration (NOAA) hydrographic data is typically acquired using sonar systems, with a small percent acquired via airborne lidar bathymetry for near‐shore areas.

Sedimentology, EarlyView.ABSTRACT This research examines the spatial and geochemical interactions between mat‐forming microorganisms and thalassinid shrimp in an intertidal flat situated on the shores of Willapa Bay, Washington, USA. The study serves as a contemporary analog for the relationships between mats and burrowing organisms in deep time.

A conventional approach for comparing vertical reference frames
Journal of Geodetic Science, 2012 A conventional transformation model between different realizations of a vertical reference system is an important tool for geodetic studies related to precise vertical positioning and physical height determination.

Sedimentology, EarlyView.ABSTRACT Tsunami deposits serve as geological records of past events and are essential for understanding the occurrence and dynamics of tsunamis. However, conventional research has largely focused on sandy and boulder deposits, leaving gravel‐dominated tsunami deposits comparatively underexplored; furthermore, their characteristics and formation ...

The united geodetic vertical network of Latvia and Lithuania
Geodesy and Cartography, 2012 A unified and continuous national vertical network is the back-bone for geodesy, cartography, civil engineering and global positioning. International institutions are working to reach homogenous and unified vertical datum all around the globe.

Readjustment of the national geodetic vertical datum
Eos, Transactions American Geophysical Union, 1980 New geodetic techniques and computer technology are providing scientists in the United States and other countries of North America with the precise tools needed to modernize the North American horizontal and vertical geodetic control networks—a web of geodetic survey monuments that spans the continent.

A quality investigation of global vertical datum connection [PDF]
Geophysical Journal International, 1992 SUMMARY Vertical datum connection is investigated from the viewpoint of quality, i.e. accuracy and reliability, based on the method originally proposed by Rummel & Teunissen (1988). Three simulations are carried out. The levelling accuracy is assumed to be 1 mmkm-1 and the position accuracy of space stations 5 cm. The three error models of the geoid

Loess Studies in Aotearoa New Zealand
New Zealand Journal of Geology and Geophysics, Volume 69, Issue 2, June 2026.Loess in Aotearoa New Zealand (ANZ) has been studied since its first documented recognition (on Banks Peninsula) in 1878 by Julius von Haast. A decade later, John Hardcastle revealed that southern ANZ loess was both glacial in origin and contained signals of past climates.
