blog regularity 

Accidental Remediation [2014-07-23 02:20:00]  recommend  recommend this post  (12 visits) info
I've been able to post more regularly for a while now, and I attribute that to a few specific changes: 1. Every time I have a thought for a blog post while working in the office, I write it on a post-it note. Then I immediately stuff it in a pocket and bring it home, where it gets added to a pile of other post-it notes. I do something similar in the field or while in transit - I rip off a

Benchmarking Time: DC is all about boundaries

Washington DC is an interesting city. When the original plans were being made in the 1780s and 1790s, they called for a 100-square-mile area to be allocated for the city, and George Washington (who was President at the time) wanted to include the City of Alexandria in Virginia. But the Residence Act, passed in 1791, specified that all the federal buildings had to be on the Maryland side of the river (mostly because someone realized that the law allowed the President to choose the location and [...]

New Round Of Warnings For Mt Fuji

Apparently the news media wants to remind you of the dangers posed by Mt Fuji, who's magma chamber has been pressurized to unprecedented levels following 2011's major 9.0 earthquake in Japan. A 6.4, and 5.0 quake followed, centered under Mt Fuji, which has caused some concern for scientists and nearby cities. I reported on this over two years ago, and while not much has changed, it seems that this is back in the headlines again, so I thought I'd set the record straight, lest the news media [...]

My apologies for the light blogging recently. I was traveling in the US for three weeks, and now I am traveling for work for 6 weeks. I will do my best to blog when I can, but blogging may continue to be light for a little while longer since I’m currently working 12 hour shifts in the field. However, when I return in September I will be taking some time

At the moment I (Ken Fergason) am the Vice President/President-Elect of the Association of Environmental & Engineering Geologists (AEG) and I will become President at our Annual Meeting in September (It's in Scottsdale, AZ and it's going to be an awesome meeting).

In November 2013, a full moon and high tides led to flooding in parts of the city, including here at Alton Road and 10th Street. Photograph: CorbisFor those of us in the earth sciences it is kind of mind-boggling to believe that some people still think that climate change is a hoax foisted on us only by liberals or communists. There is a billion-year record of climate change that exists in the rock record and it clearly shows that Earth's climate is subject to change. And there is a [...]

On the weekend 11-13 July 2014 various Australian government institutions had invited to join GovHack 2014. Governments collect and publish enormous amounts of data, but have limited resources to get it into the hands of their citizens in engaging ways. GovHack is an event to draw together people from government, industry, academia and of course, the general public to mashup, reuse,

I guess the answer to this question is "no," since in the two years I haven't been posting regularly only two of my regular readers asked me when I was going to write again (thank you, Beth Merritt and Carl Zimmer). Not that I care. Like most bloggers, I suspect, I write for myself, to rehearse arguments and develop ideas that I use elsewhere. If the rest of you enjoy it, so much the better. But it's an essentially selfish pursuit.Why did I stop? Well, I'd like to tell you that it was because [...]

I'm spending time this summer with MS students Thomas Liner (blue shirt) and John Guist (red hat). Recently we had a day in the lab trying to get the EM–31 conductivity meter figured out. Thomas worked through every manual we have and found out that batteries were dead or depleted, the system had been stored with power on, and we were missing some software on the PC. After a drydock experiment in the lab, we took it out in front of Ozark Hall for a couple of test lines. Returning to the [...]

Previously I had posted on "What is the most common mineral on Earth?", well some recent discoveries have come to light that have made me go back to that original post and update it. When I had originally published the post I had stated that:"Looking at the bulk composition of the Earth the most common mineral is generally regarded as olivine since the mantle makes up the bulk of the Earth and olivine makes up the bulk of the mantle." That statement had produced a couple of comments (not [...]

I came upon this plate of shale in a small quarry near the town of Fayette in New York. It comes from the Levanna Shale of the Skaneateles Formation and is covered with brachiopod fossils called Leiorhynchus multicostus (aka Eumetabolatoechia multicostatum). Leiorhynchonellid type brachiopods are often common in black shales which indicate that they were tolerant of conditions with lower oxygen content. In this case there must have been a period or time where the conditions were right and the [...]

Darren Naish and John Conway will be hosting the first TetZooCon in eleven short days, at the London Wetland Centre. I have been drooling over the announced speaking lineup since I learned of it, but with an ocean between us, it's just not in the cards for me. The deadline for booking your place at the event is this Friday, July 4. At £40, the price is very reasonable (if only airfare and lodging didn't cost anything). John opens the conference with his welcome, followed by Darren on [...]
