Concerns about global warming… since the 1930s

Maribo | 29 July, 2014
"Gaffers who claim that winters were harder when they were boys are quite right--except that the change is too small to be detected except by instruments and statistics in the hands of professional meteorologists. Weather men have no doubt that the world at least for the time being is growing warmer."

Deep Blue Water and a Roller Coaster Ride

Notes from the field | 29 July, 2014
After just over a full week at sea, we have found the rhythm of our life and work routines. We collect water with the CTD rosette, deploy instruments over the side of the ship, work in the lab, eat, and sleep. That might sound like a lot of work and no play, but we do manage to have fun while we work (think lab dance party while filtering water samples). We've also taken time to observe the vast blue around us from the upper deck of the ship, where we recently watched a gorgeous sunset. No green flash sightings yet but I continue to hold out, hoping to see this optical phenomenon - a green flash of light that can sometimes be seen just before the sun disappears below the horizon.

New Solite excavation

In the case of the Solite Quarry, mining operations have recently increased and now encompass the unique insect bed that VMNH has been excavating for many years. In an effort to preserve as much of the deposit as possible, National Geographic has provided a grant to VMNH to conduct a salvage operation at Solite.

The larvae of an Apochrysinid Green Lacewing.

Graphics that repay careful study

Agile Geoscience | 29 July, 2014
The Visual Display of Quantitative Information by Edward Tufte (2nd ed., Graphics Press, 2001) celebrates communication through data graphics. The book provides a vocabulary and practical theory for data graphics, and Tufte pulls no punches -- he suggests why some graphics are better than others, and even condemns failed ones as lost opportunities. The book outlines empirical measures of graphical performance, and describes the pursuit of graphic-making as one of sequential improvement through revision and editing. I see this book as a sort of moral authority on visualization, and as the reference book for developing graphical taste.

Asteroid 2014 MG55 passes the Earth.

Sciency Thoughts | 29 July, 2014
Asteroid 2014 MG55 passed by the Earth at a distance of about 10 080 000 km (26.22 times the average distance between the Earth and the Moon, or 6.7% of the average distance between the Earth an the Sun), slightly after 12.25 pm GMT on Friday 25 July 2014. There was no danger of the asteroid hitting us, though were it to do so it would have presented a serious threat. 2014 MG55 has an estimated equivalent diameter of 28-90 m (i.e. it is estimated that a spherical object with the same volume would be 28-90 m in diameter), and an object towards the upper end of this range would be predicted to be capable of passing through the Earth's atmosphere relatively intact, impacting the ground with an energy equivalent to about 35 megatons of TNT (roughly 2000 times the energy of the Hiroshima bomb). Such an event would result in a crater about 1 across, cause devastation on a wide scale and would have the potential to affect the climate globally for years after the impact event.

Oso landslide: differences of opinion about the landslide mechanisms

The Landslide Blog | 29 July, 2014
The journal Science is reporting an interesting public argument about the mechanisms of the Oso landslide in Washington State, USA.  This is between the authors of the GEER report (NB pdf), which was released last week, and Dr Richard Iverson of the USGS, and is in essence about the chronology of events that generated the very rapid debris flow event that was so costly.  I wrote about the GEER report last week, and noted that they interpret the sequence as being a two-fold failure event, as indicated by the seismic data. The latter is not controversial - there is a nice (pdf) report from the Pacific Northwest Seismic Network that shows this double event very clearly:
