The Cedar Creek site report is now assembled. Take a look at it here and let me know if there are any changes you suggest or errors you find. This is the format for your project – GSA format take a good look […]

Two of the compilation diagrams for the Mastodon site are included below (yes they will be on the quiz):

1 – Photos of the units, stratigraphic column, C-14, LOI and Magnetics (write a caption for it).

2 – […]

As the weather cools – the Wooster Geology Climate Change class ventured out in the field one more time. For the remainder of the semester we will try to get some work done. Two sites were visited – the Cedar […]

This glacial erratic made is way down to Wayne County during the course of the 20 glacial cycle over the past 2 million years. Before that is was buried and exhumed in the earth’s crust to a depth of ov […]

The diagram above came up in the Emily and Sarah’s presentation. This is for recent climate change relevant to the warming world of today. What might this look like for glacial times, for longer timecales? […]

One of the big questions that remains with the Mastodon site is how does the marl in our cores link to the excavation. Clint Walker had a good suggestion to dig a ditch 2 meters down through the bog. Now we have a […]

A blog that you should really subscribe to and check in on occasionally is RealClimate.
This week’s entry is concerned with – How do Trees Change the Climate? This question will become more important to us as we […]

We spent a beautiful Fall morning at the Cedar Creek Mastodon site with Dr. Wilson, Dr. Brush (U. Ashland), Dr. Kardulias and other experts examining the sediments and mastodon remains. See Dr. Wilson’s post for […]

Above is the reconstructed temperatures from the Greenland Ice Core. Now that we have radiocarbon ages from our sediment core we can put it into the larger context of the Northern Hemisphere temperature history. […]

The Wooster Geology Climate Change class spent a beautiful fall day in Stony Creek, Ohio coring beams in three structures of historical significance. They will determine the cut dates (calendar dates when the […]

 Picking seeds from a critical layer of mud – the seeds will be sent out for radiocarbon analysis.

An important step was photographing the cores.

Some of the smear slides required a petrologic scope to see […]

Our Climate Change class visited Browns Lake Bog with the Plant Com […]

Tom Lowell and graduate student Stephanie Allard from Cincinnati and Jacqueline Rodriguez from the University of Illinois made the trip to Morrow County to core mud from a bog adjacent to the Cedar Creek Mastodon […]

Saturday is the Coring of the Cedar Creek Mastodon Site with Dr. Lowell (University of Cincinnati) and Jacklyn Rodriguez (University of Illinois). Tom Lowell truly is the Core Boss and is remarkable when it comes […]

Above graphic taken from a 2006 report by Lowell and others coring lakes in northern Minnesota. Dr. Lowell is on the right without a coat. Henry Loope is in the middle (Henry sent us 20,000 year old LGM wood from […]

Wooster’s Climate Change class is starting the semester by  coring a bog adjacent to a recent Mastodon find in Morrow County, Ohio. The Mastodon work and related excavation is being led by Nigel Brush, Un […]

2013 was tied for the fourth warmest year since we have been keeping track of global temperatures over the last 150 years. This course is an exploration of climate basics, paleoclimatology and contemporary […]

Monday we will meet in Lean Lecture Hall at 8 AM with Gidon Bromberg, who will be giving the forum talk Monday evening – Water and Middle East Peace – Challenges and Opportunities (7:30 PM).

Along the li […]

The Geology of Oil and Gas is an overview of petroleum geology, the oil industry, and its geopolitics. This course is 0.25 credits and will meet in Scovel 116 each Friday afternoon between 2:30 and 3:50. […]
