It was prepared under the direction of the Canadian National Committee for the International Union of Geodesy and Geophysics (CNC/IUGG). The CNC/IUGG is administered by the Canadian Geophysical Union, in consultation with the Canadian Meteorological and Oceanographic Society and other Canadian scientific organizations, including the Canadian Association of Physicists, the Geological Association of Canada, and the Canadian Institute of Geomatics. The IUGG adhering organization for Canada is the National Research Council of Canada. Among other duties, the CNC/IUGG is responsible for: • collecting and reconciling the many views of the constituent Canadian scientific community on relevant issues • identifying, representing, and promoting the capabilities and distinctive competence of the community on the international stage • enhancing the depth and breadth of the participation of the community in the activities and events of the IUGG and related organizations • establishing the mechanisms for communicating to the community the views of the IUGG and information about the activities of the IUGG. The aim of this report is to communicate to both the Canadian and international scientific communities the research areas and research progress that has been achieved in geodesy and geophysics over the last four years. The main body of this report is divided into eight sections: one for each of the eight major scientific disciplines as represented by the eight sister societies of the IUGG.

The largest variations, with direction from the baseline indicated 37 using plus and minus signs, and in decreasing order, occur at 14-25 km depths in continental transform (+), 38 oceanic ridge/transform (+), continental rift (+), Himalayan-type (+), island arc-type (-) and Andean-type (- 39 ) margins. At 25-37 km depths, variations one-fifth the size occur in continental rift (+), island arc-type 40 (+), Andean-type, (-), Himalayan-type (-), oceanic ridge/transform (-), and continental transform (-) 41 margins. Below 37-km depth, variations one-tenth the size occur in Andean-type and Himalayan-type 42 margins to depths of about 260 km. Energy release in island arc-type margins closely tracks the baseline to 43 the maximum depth of earthquakes at 699 km. The maximum depth of earthquakes in Andean-type and 44 Himalayan-type margins is 656 and 492 km, respectively, while in divergent and transform margins it is 45 about 50 km.

Abstract This is a status report on (near) geosynchronous objects as of 1 January 2019. Based on orbital data in ESA’s DISCOS database and on orbital data provided by KIAM the situation near the geostationary ring is analysed. From 1578 objects for which orbital data are available (of which 14 are outdated, i.e. the last available state dates back to 180 or more days before the reference date), 529 are actively controlled, 831 are drifting above, below or through GEO, 195 are in a libration orbit and 21 are in a highly inclined orbit. For 2 object the status could not be determined. Furthermore, there are 60 uncontrolled objects without orbital data (of which 55 have not been catalogued). Thus the total number of known objects in the geostationary region is 1638. Finally, there are 130 rocket bodies crossing GEO.

    Adam Marian Dziewoński Was Spread Upon the Permanent Records of the Faculty

    At a meeting of the FACULTY OF ARTS AND SCIENCES on November 7, 2017, the following tribute to the life and service of the late Adam Marian Dziewoński was spread upon the permanent records of the Faculty. ADAM MARIAN DZIEWOŃSKI BORN: November 15, 1936 DIED: March 1, 2016 Adam Marian Dziewoński was born in Lwów, Poland (now Lviv, Ukraine) and received his M.S. in 1960 from the University of Warsaw and his Doctor of Technical Sciences in 1965 from the Academy of Mines and Metallurgy in Krakow. He moved to the United States in 1965 as a research associate at the Graduate Research Center of the Southwest in Dallas and became an assistant professor at University of Texas at Dallas in 1969. Adam moved to Harvard University as an associate professor in 1972, became a full professor in 1976, and was named the Frank B. Baird, Jr., Professor of Science in 1994. He was the chair of the Department of Geological Sciences between 1982 and 1986 (Department of Earth and Planetary Sciences thereafter). He retired in 2009 but remained actively engaged in research until his death. Adam was born in a year of seismological significance, the year in which the Earth’s inner core was discovered. As if fated, Adam was involved in all subsequent major discoveries about this deepest layer of Earth. With James Freeman Gilbert, Adam provided the first direct evidence that the inner core is solid, settling the debate over its nature. He continued his work on the inner core with his colleagues at Harvard and went on to show that it is anisotropic, rotates at a slightly different rate than the mantle, and has another layer at its center.

Any opinions expressed in this memoir are those of the author and do not necessarily reflect the views of the National Academy of Sciences. DON LYNN ANDERSON March 5, 1933–December 2, 2014 Elected to the NAS, 1982 Don L. Anderson, the Eleanor and John R. McMillan Professor of Geophysics at the California Institute of Tech- nology, was a geophysicist who made numerous seminal contributions to our understanding of Earth’s origin, composition, structure and evolution. He pioneered applications of seismic anisotropy for global surface waves, contributed to discovering the seismic velocity discontinuities in the mantle’s transition zone and initi- ated their mineralogical interpretation, established deep insights into seismic attenuation, co-authored the most widely used reference Earth structure model, helped to establish the field of global tomography, and re-opened inquiry into the nature of hotspot volcanism and mantle stratification. He contributed to initiatives that upgraded By Thorne Lay global and regional seismic instrumentation. He served as Director of the Caltech Seismological Laboratory for 22 years, overseeing a prolific scientific environment, distilling many advances into his masterpiece book Theory of the Earth. His enthusiasm for debate and his phenomenal editorial efforts raised the scientific standard of students and colleagues alike. Don was a geophysicist of tremendous breadth, publishing about 325 peer-reviewed research papers between 1958 and 2014 in seismology, mineral physics, planetary science, tectonophysics, petrology and geochemistry. He had a remarkable familiarity with the literature across all these disciplines, keeping reprints sorted into a multitude of three-ring binders that he could access in an instant, uniquely positioning him to undertake the writing of his ambitious book, The Theory of the Earth, published in 1989.
