Autonomous multi-drone aerial surveys Antarctic penguin colonies
2020/11/13
Scientist Mac Schwager at Stanford University, an aeronautics and astronautics researcher, learned that biologists were seeking a better way to image a large penguin colony in Antarctica. Schwage...
THE 2012 EARTHQUAKE: AN ABACUS OF SURVEYS AND INTERVENTIONS IN MANTUA CHURCHES
Survey geomatics earthquake seismic damage cultural heritage
2017/6/20
After the earthquake of 2012, the ecclesiastical heritage of Mantua was so damaged to render unusable many buildings. Especially churches show a higher vulnerability in relation to their architectural...
Association between household unavailability of iodized salt and child growth: evidence from 89 demographic and health surveys
childhood undernutrition demographic and health surveys iodine iodine deficiency iodized salt low- and middle-income countries
2018/12/14
Background: Although a strong biological basis exists for a role of iodine in somatic growth failure in childhood, this relation has not been previously studied on a large scale to our knowledge.

Background: Although a strong biological basis exists for a role of iodine in somatic growth failure in childhood, this relation has not been previously studied on a large scale to our knowledge.
Hydrographic surveys of ports and harbours are undertaken primarily to support the safe navigation of vessels. Port authorities are charged with maintaining and developing their harbours with regard t...
The Osservatorio Geofisico Sperimentale marine magnetic surveys in the Antarctic Seas
Marine magnetic and gradiometric profiles sea-floor magnetic anomalies tectonic reconstructions
2015/10/8
About 40 000 km of marine magnetic and gradiometric data have been collected during eight geophysical surveys conducted since the Austral summer 1987/1988 in the circum-antarctic seas, by the research...
A new geomagnetic observatory at Livingston Island (South Shetland Islands): Implications for future regional magnetic surveys
Geomagnetic observatories magnetic surveys magnetic anomalies
2015/10/8
A pennanent geomagnetic observatory is always the ideal reference station for monitoring geomagnetic activity during airborne, marine or ground magnetic surveying, especially in Antarctica, where logi...
Fast representation of dipole-dipole geoelectrical data with pseudosections for regional surveys
Electrical sounding dipole-dipole methods apparent resistivity deep sounding data processing
2015/9/28
I propose a fast method for constructing pseudosections of apparent resistivity from geoelectrical data collected for deep studies with continuous polar dipole-dipole arrays. Once a vertical section i...
Geodetic deformations in the Central-Southern Apennines (Italy) from repeated GPS surveys
Geodesy GPS central-southern apennines strain rate seismotectonic
2015/9/28
We computed the horizontal strain rate field for a sector of tbc Central-Southern Apennines (Italy) from GPS data collected during yearly repeated campaigns performed from 1994 to 2000 on tbc GeoModAp...
High-resolution marine magnetic surveys for searching underwater cultural resources
High-resolution marine magnetic surveys marine archaeological search ship-wreck amphorae
2015/9/8
Recently two marine magnetic surveys, combined with the use of a multi-beam sonar (Kongsberg Marittime EM

Repeat-station surveys: implications from chaos and ergodicity of the recent geomagnetic field
Magnetic repeat stations Chaos Ergodicity
2015/8/18
The present geomagnetic field is chaotic and ergodic: chaotic because it can no longer be predicted beyond around 6 years; and ergodic in the sense that time averages correspond to phase-space average...
Density-thermal dependence of sedimentary associations calls to reinterpreting detailed gravity surveys
Temperature Density Subvertical zone Gravity anomaly
2015/8/14
The modern gravimetric equipment allows to register very small effects of gravity field changes and can be applied solving different geological, geophysical and environmental problems. However, someti...
