125 years of exploration and research at Gough's Cave (Somerset, UK) 125 ans d'exploration et de recherches à Gough's Cave (Somerset, Royaume‐Uni)

Journal of the Royal Anthropological Institute, EarlyView.
Our understanding of the recolonization of northwest Europe in the period leading up to the Lateglacial Interstadial relies heavily on discoveries from Gough's Cave (Somerset, UK). Gough's Cave is the richest Late Upper Palaeolithic site in the British Isles, yielding an exceptional array of human remains, stone and organic artefacts, and butchered ...

Modelling non‐linear psychological processes: Reviewing and evaluating non‐parametric approaches and their applicability to intensive longitudinal data

British Journal of Mathematical and Statistical Psychology, EarlyView.
Abstract Psychological concepts are increasingly understood as complex dynamic systems that change over time. To study these complex systems, researchers are increasingly gathering intensive longitudinal data (ILD), revealing non‐linear phenomena such as asymptotic growth, mean‐level switching, and regulatory oscillations.

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.

Determination of geopotential of local vertical datum surface

Geo-spatial Information Science, 2003
This paper first develops the approaches to determine the geopotential of the local mean sea level, and then investigates the offset of the 1985 vertical datum surface defined by the mean sea level of Yellow Sea at the Dagang Tide Gauge in Qingdao city using the developed approaches and GPS/leveling data.

A limpet's eye view of post‐glacial isostasy: fixed biological indicators provide new sea‐level index points for the Mid‐Holocene relative highstand in eastern Northern Ireland

Boreas, EarlyView.
Bioerosional scars made by limpets (Patella) on a cliff in Co. Antrim, Northern Ireland, indicate a Mid‐Holocene RSL of +7.8±0.55 m relative to local mid‐tide level today. This is higher than previous empirical data for the region and extrapolated levels from raised shorelines in Scotland but consistent with some recent GIA models.

Bull trout (Salvelinus confluentus) exhibit binge‐feeding and digestive flexibility during seasonal resource pulses associated with salmon migrations

Journal of Fish Biology, EarlyView.
Abstract Resource pulses are infrequent, ephemeral events of resource hyperabundance that can represent important feeding opportunities for consumers. To capitalize on pulsed resources, consumers can exhibit behavioural and physiological traits including binge‐feeding and phenotypic plasticity of digestive physiology, although expression of these ...

Análisis de la evolución temporal del datum vertical brasileño de Imbituba

Revista Cartográfica, 2019
Actualmente, los temas más centrales de Geodesia se vinculan a la provisión de un Sistema de Referencia Global único, al que puedan vincularse de forma unívoca y con exactitud los cambios globales de carácter geométrico y físico.

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

Airborne Gravity Across New Zealand - For An Improved Vertical Datum

, 2016
It is important to be able to accurately determine the height of a point on the Earth in terms of the Earth's gravitational potential field. These heights predict how water will flow and so they are vital for engineering and surveying purposes.
