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.
Director's Weekly Reports
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.
Arriving at Lamont this week was Jonathan Kingslake, a new Assistant Professor in the Department of Earth and Environmental Sciences. Jonny received his Ph.D. in glaciology in 2013 from the University of Sheffield, where he studied subglacial water flow and outburst floods with Felix Ng and Grant Bigg. As a glaciologist at the British Antarctic Survey between then and now, he led field expeditions to West Antarctica to document annual changes in ice sheet structure and longer-term ice flow patterns with phase-sensitive radar measurements.
This week the Alfred P. Sloan Foundation announced that Ryan Abernathey has been selected as a Sloan Research Fellow for 2016 (http://www.sloan.org/sloan-research-fellowships/2016-sloan-research-fell...).
The Weekly Report this week is shorter than usual because I spent much of the week off campus. From Wednesday to Friday I attended a meeting of the GRAIL Science Team hosted by the University of Hawai’i. The highpoint of the meeting was a daylong field trip, led by Jeff Taylor and Peter Mouginis-Mark of the university’s Hawai’i Institute of Geophysics and Planetology, of the deposits and structures of the Ko’olau volcano in southeastern Oahu.
The scientific highlight of the week was distant from the Earth and environmental sciences but spectacular nonetheless: the announcement on Thursday of the first clear detection of gravitational waves (http://www.nytimes.com/2016/02/12/science/ligo-gravitational-waves-black...).
Once again we experienced a week bookended by a snowstorm, this one at the end rather than the beginning. Once again, our Buildings and Grounds crew were in early today to clear roads, paths, and parking lots even as the snow continued to fall.
This week began with a snowstorm that set accumulation records at several locations across the northeastern U.S. The brunt of the storm arrived Saturday, and by mid-morning Sunday the skies were clear. That schedule permitted our crew from Buildings and Grounds to clear all the pathways, roads, and parking lots by the start of work on Monday morning, an amazing transformation of the campus that required long weekend hours on the part of many.
One of the main news stories this week was the announcement Wednesday by the National Oceanic and Atmospheric Administration and NASA’s Goddard Institute for Space Studies (http://www.nytimes.com/2016/01/21/science/earth/2015-hottest-year-global-warming.html?_r=0) that 2015 was the hottest on record.
This week marked the first campus snowfall of this winter season. Notwithstanding the limited accumulation, our Buildings and Grounds staff were in early Thursday morning to ensure that roads, sidewalks, pathways, and parking lots were clear and safe.
The first weekly report of the new calendar year provides a good opportunity to mention several recent arrivals to the campus.
It has been another holiday-shortened week, one in which temperatures in the New York City area returned to seasonal levels after the record-setting highs of last week. A CNN blog by Adam Sobel (http://www.cnn.com/2015/12/25/opinions/sobel-warm-december/), posted on Christmas Day, explained that the high December temperatures in the eastern U.S.
