We are at the midpoint in the quadrennial national gatherings of the two major U.S. political parties. The Republicans completed their convention in Cleveland yesterday, and the Democrats take their turn in Philadelphia next week.
Director's Weekly Reports
To those of us striving to improve the stewardship of our planet, the savage acts that lately fill world news reports are deeply disturbing. The tragedies in Dallas and Nice remind us that our species, for all its accomplishments, can commit natural disasters every bit as devastating as those we study in Lamont’s laboratories. We can hope that progress on understanding and mitigating the worst aspects of human behavior will proceed apace with progress on understanding and mitigating the changes to our planet that humans collectively have set in motion.
The week was ushered in with fireworks as we all celebrated an 18th Century version of Brexit.
This week included the end of an academic and university fiscal year on Thursday, and the beginning of a new year today. A flurry of personnel and budget activities marked the lead-up to the change in the calendar.
Noteworthy among them are three promotions on the Lamont research faculty, all effective today. Natalie Boelman and Michael Previdi have been promoted to Lamont Associate Professor, Senior Staff, and Jonathan Nichols has been promoted to Lamont Associate Professor, Junior Staff. To Natalie, Michael, and Jonathan, congratulations!
Monday was the summer solstice, when solar zenith reached its maximum northern extent, the Tropic of Cancer. We’ve enjoyed more daylight this week than any other week of this calendar year.
The Earth and Planetary science community mourned the death this week of Jerry Wasserburg, isotope geochemist and cosmochemist, Crafoord Laureate, and long-time member of the faculty at Caltech. Jerry’s laboratory largely defined the history of the Moon and established the timescale between nucleosynthesis and solar system formation.
This week included World Oceans Day (http://www.worldoceansday.org/), “a global day of ocean celebration and collaboration for a better future.” The theme for the day, which fell on Wednesday, was “healthy oceans, healthy planet,” worthy goals for all of us.
Although shortened by a Monday holiday, the week was one in which scientific progress continued at the usual pace.
A second week in a row began with sad news for the extended Lamont family, with a belated report that Columbia and Lamont alumnus Charles Officer, Jr., had passed away last month (http://www.vnews.com/Obituaries/Charles-Officer-Obituary-Hanover-NH-1518946). A theoretical geophysicist with broad interests, Chuck was well known as the author of several textbooks and a number of popular books in Earth science.
The week began sadly for the extended Lamont family with the news that one of our most distinguished members, John Imbrie, passed away last Friday. Considered one of the founders of modern paleoceanography, John taught at Columbia's Department of Geological Sciences (now the Department of Earth and Environmental Sciences) from 1952 to 1967 and served as department chair. The recipient of many awards and honors, John shared the 1996 Vetlesen Prize.
This week began with a transit of Mercury, an event that occurs only about 13 times per century (http://www.nytimes.com/2016/05/11/science/mercurys-colorful-path-across-the-sun.html?_r=0). The passage of Mercury between the Sun and Earth permits novel measurements of Mercury’s tenuous atmosphere and serves as an observational analog to extrasolar planets that transit their host stars.
The highlight of the first half of this week for the Lamont community was the election on Tuesday morning of Maureen Raymo to the National Academy of Sciences (http://www.nasonline.org/news-and-multimedia/news/may-3-2016-NAS-Election.html).
It is worth a few moments to celebrate the birthday today of chemist Harold Urey, whose discovery of deuterium in 1932 while on the Columbia faculty was recognized with a Nobel Prize two years later. Following his work on the Manhattan Project, Urey made seminal contributions that helped to establish the fields of cosmochemistry, planetary science, and what is now called astrobiology.
The week began Saturday with large, damaging, and deadly earthquakes on opposite sides of the Pacific. The first was a magnitude 7.0 earthquake in central Kyushu, Japan, a shallow strike-slip rupture that had been preceded by a magnitude 6.2 foreshock two days earlier (http://www.nytimes.com/2016/04/17/world/asia/more-than-40-in-japan-are-confirmed-dead-in-earthquakes.html).
Today’s date makes me think of income taxes. This year, as with the past several, the hectic spring schedule forces me to throw up my hands and file for extensions on federal and state taxes so I can finish gathering the needed information over the summer.
The spring schedule, of course, sometimes brings good news. This week, Peter Schlosser learned that he has been elected to membership in the German National Academy of Sciences. Founded in 1652, the organization is the oldest continuously operating scientific academy in the world. Congratulations, Peter!
Late last week, the Observatory was saddened by the news that a member of the Lamont extended family had passed away. Michael Vitelli, who worked as a Systems Analyst for Columbia University for nearly 10 years, first on the Morningside Campus and then at Lamont, died at the age of 52 on March 30 in Nyack after a long illness (http://www.legacy.com/obituaries/lohud/obituary.aspx?n=michael-j-vitelli&pid=179474380&fhid=14974).
The week was notable for the announcement yesterday by President Obama and President Xi Jinping of China that the two nations would both sign the Paris climate change agreement on Earth Day, three weeks from today at a signing ceremony at the United Nations (http://www.nytimes.com/2016/04/01/world/asia/obama-and-president-xi-of-china-vow-to-sign-paris-climate-accord-promptly.html?_r=0).
Margie Turrin learned last week that she is to receive this year’s Distinguished Service Award from the Rockland County Municipal Planning Federation. Margie was recognized for her leadership of the Rockland Planning Land Use for Students (RPLUS) program (http://www.ldeo.columbia.edu/edu/plus/). A milestone event for the program was a symposium last Friday, held at SUNY Rockland Community College, at which the RPLUS students presented their community project to mentors from the county. Congratulations, Margie!
The week began with a double dose of sad news: the loss from the Lamont family of Jay Ardai and Arnold Finck, both of whom passed away on Sunday.
The week we were reminded that Earth shares the solar system with other objects. The Moon passed between the Sun and Earth on Tuesday night (our time) and produced a solar eclipse visible in its totality from Indonesia. And one day earlier, asteroid 2013 TX68 – 20 to 50 m across – passed within about 4 million kilometers of Earth (http://earthsky.org/space/asteroid-2013-tx68-uncertain-trajectory-closest-earth-mar-5-2016), about 10 times the distance between Earth and the Moon.
