Fielding Receives 2016 Ivan I. Mueller Award for Service and Leadership


Eric Jameson Fielding (NASA JPL) received the 2016 Ivan I. Mueller Award for Distinguished Service and Leadership at the 2016 American Geophysical Union Fall Meeting, held 12–16 December in San Francisco, California. The award recognizes “major achievements in service and/or leadership to the geodesy community.”






Officialization of the National Vertical System (new Argentinean Height System)


On December 2, 2016, the Instituto Geográfico Nacional (IGN –National Geographic Institute) presented and officialized the new Argentinean Height System. This project, which started in 2010, was comprised of the following stages: a) determination of a new absolute gravity network; b) determination of a new first-order gravity network; c) readjustment of the second-order gravity network; d) determination of new physical heights for all of the spirit-leveling network benchmarks; and e) determination of a new gravimetric geoid model.

Regarding the new absolute gravity network (RAGA), 36 homogeneously distributed sites were measured using two Micro-g LaCoste A10 gravity meters provided by the Universidade de São Paulo (USP – University of San Pablo, Brazil) and the Institut de Recherche pour le Développement (IRD – Institute of research for the development, France). The accuracy of the computed gravities was 0.020 mGal.

Regarding the new first-order gravity network (RPO-Ar), 227 sites were measured using five relative gravimeters: three LaCoste & Romberg model G and two Scintrex CG-5. These instruments were provided by the IGN, Universidad Nacional de San Juan (UNSJ – National University of San Juan, Argentina), Universidad Nacional Rosario (UNR – National University of Rosario, Argentina), and Universidad Nacional de La Plata (UNLP – National University of La Plata, Argentina). The measurements were adjusted using the GRAVDATA (Drewes 1978) and GRADJ (Forsberg 1981) software. Additionally, the Hartmann and Wenzel (1995) tidal potential catalogue was applied. The gravity observations were constrained at the 36 absolute RAGA sites. The final adjusted gravity observations have a standard error of less than ± 0.025mGal.

Regarding the second-order gravity network (RSO-Ar), it is composed of 13,871 points that are co-located with the first-order spirit-leveling network. IGN started the RSO-Ar measurements in 1948 and, therefore, different gravimeters (e.g. Western, Worden, LaCoste & Romberg and Scintrex) have been used for determining the gravities. As with RPO-Ar, gravity observations were processed and adjusted to the RAGA and RPO-Ar networks using the same specialized software and other computer programs developed at the IGN. The standard error of RSO-Ar was estimated to be  ± 0.10mGal.

Regarding the National spirit-leveling network (composed by 2,020 spirit-leveling lines and ~ 143,000 km), the new physical heights (geopotential numbers) of 33,891 benchmarks were computed using a least-squares adjustment. Then, orthometric heights (Mader 1954) were determined for each benchmark. The topographic correction was computed using the digital elevation model SRTM_v4.1 (Jarvis et al. 2008) and the method described by Bott (1959). The Argentinean geopotential value W0 is 62,636,853.8 m2s-2 (Tocho et al. 2015) and, therefore, the difference with respect to the W0 proposed by the International Association of Geodesy in Resolution No. 1 of 2015 is 0.4 m2s-2.

Finally, a new gravimetric geoid model named GEOIDE-Ar16 was developed using the remove-compute-restore technique. A combination of the GOCO05S satellite-only global geopotential model together with 658,111 land and marine gravity observations were used for the new model determination. Terrain corrections were calculated using a combination of the SRTM_v4.1 and SRTM30_Plus v10 DTMs for all gravity observations. For the regions that lacked gravity observations, the DTU13 world gravity model was utilised for filling-in the gravity voids. The residual gravity anomalies were gridded using the Kriging method and the resultant grid was applied in the Stokes’ integral using the spherical multiband FFT approach and the deterministic kernel modification proposed by Wong and Gore (1969).

Heinz Günther Henneberg (1926 – 2016)


On November 4, 2016, Prof. Dr. Heinz Günther Henneberg, The Zulia University, Maracaibo, Venezuela, passed away at the age of 90 years.

Heinz G. Henneberg was born on January 22, 1926 in Northern Germany. After losing the time of his adolescence as a young soldier in World War II, he studied Geodesy and Civil Engineering at the Universities of Technology in Braunschweig and Hannover and graduated as engineer in Geodesy (Dipl.-Ing.) in 1953. Immediately after his graduation he was entrusted with the leadership of the survey work of two large engineering projects, namely the northern Rhine Bridge in Düsseldorf, Germany, and the Maracaibo Bridge in Venezuela, at that time the longest cable-stayed bridge of the world (8678 m). The tolerance of 2 cm in position and height of the 6 pylons and 135 pillars for mounting the prefabricated concrete elements was an extreme challenge for the surveying by triangulation and trigonometric levelling (back then without electronic instruments). He completed his doctorate at Hannover University in 1962 (Dr.-Ing.) with a thesis on the scientific research of methods and realisation of these two projects.

As a consequence of his excellent work he was appointed to a professorship at The Zulia University (LUZ), Maracaibo, Venezuela, in 1961, which determined his future life. He was engaged in the survey work of many engineering projects in Venezuela (e.g. the Angostura Bridge spanning the Orinoco, the Rio Limón Bridge in mangrove swamp, and the Guri Lake dam) and their continuous control. Subsequently he broadened his activities to the monitoring of crustal deformation in the subsiding petroleum region along the eastern coast of the Lake of Maracaibo and the horizontal displacements along the boundary zone between the Caribbean and South American tectonic plates (Boconó Fault). From 1966 to 1969 he was the Director of the Geodetic School at LUZ and became President of the Venezuelan Association of Geodesy in 1975. He was member of many national and international professional and scientific federations and received several awards and prizes.

Heinz Henneberg was active in the International Association of Geodesy as Secretary of the Section I “Positioning” from 1979 to 1987, President of the Sub-commission for South America of the “Commission on Recent Crustal Movements (CRCM)” from 1983 to 1995 and Co-President of the joint Working Group “Inter-American Integration of Geodetic Networks” of IAG and the Pan American Institute of Geography and History (PAIGH), which may be seen as a forerunner of the present IAG Sub-commission on the Regional Reference Frame for South and Central America (SIRGAS). In 1993 he became member of the SIRGAS Scientific Committee. During his time as the National Correspondent of Venezuela in the IAG Council he was very engaged in the Venezuelan participation in geodetic research and organised several international symposia. He privately financed the Venezuelan IUGG membership fee in periods of national budget problems.

All geodesists engaged in geodetic research in Latin America will remember Heinz Henneberg as an extremely cooperative and reliable person with many ideas and an always optimistic perspective. Scientists cooperating with him will miss a good and self-forgetful friend. They are feeling deep sympathy for his wife and his five children.
