Icy Equator

www.physorg.com id186161122 February 23rd ... some geologists think ice existed at the equator some 300 million years ago during the Palaeozoic (final stages) and research is ongoing to find out why this should be so.

Gulf of Mexico

www.physorg.com id 186089477 February 22nd ... the Little Ice Age apparently had an affect in the Caribbean and the Gulf of Mexico according to research by marine geologists - deep sea sediment samples. The region cooled by 2 degrees which is completely at odds with the 0.6 degrees from broad scale climate reconstructions - and completely gives a lie to the Mann hockey stick. 

Another Catastrophe

Science Daily February 17th ... a Nature Geoscience paper on the Carbon Cycle before humans has found that 100 million years ago there were large changes as a result of a massive amount of volcanic activity that introduced carbon dioxide and sulphur into the atmosphere. At the same time one third of marine life died out - which they suggest was due to a drop in oxygen levels in the oceans.

Lake Baikal

Daily Galaxy February 17th (www.dailygalaxy.com ) ... Lake Baikal is the oldest, the largest and the deepest lake on the planet. It's reckoned to be 25 million year of age and has a diversity of plant and animal species unknown elsewhere in the world - including the freshwater seal. Many of the unique fish in Baikal resemble deep sea species rather than freshwater ones. There are forests of sponges in the lake that resemble the Caribbean - but it is located in the sub Arctic.

Ice Shelving

www.physorg.com February 11th ... a study published in Geophysical Research Letters describes how ocean waves originating along the Pacific coasts of North and South America travel across the ocean to impact on Antarctica and it's ice shelves - those below water in the West Antarctic peninsular I assume. These waves lead to periodic collapse of the ice shelves as over time they contribute to the expansion and/or production of crevasse fields on those ice shelves.

The hole in the crust

Daily Galaxy December 27th 2009 ... in 2005 an Ethiopian volcano erupted and in the process a 35 mile rift in the landscape was created - in days (instant geology). The writer says, almost off-handedly, that nature appears to make changes much more rapidly than geology allows. However, the uniformitarian model seems to just bob up and down and take these observations on the chin without a flicker.

Pleistocene

www.physorg.com January 12th ... the Black Mesa basin in Arizona has underground aquifers created by seepage through the overlying geology. The water contains gases that provide a hint of ancient climate in the region - via palaeohydrological tools that capture noble gases such as neon and helium, elements that resist normal chemical reactions. Initial results show the aquifer was recharged during the last Ice Age and this implies the Jet Stream at that time was much further south than it is today.

Extra-terrestrial geology from several sources

http://atlas-conferences.com/c/a/j/i/26.htm claims that cosmic activity has been detected in raised bogs in NW Europe and in Siberia (at Tunguska). These traces appear to correspond to episodes of rapid climate change in the Middle and Late Holocene. Lars Franzen of the Earth Sciences Centre at Goteburg in Sweden says raised bogs are an archive of atmospheric deposition in peat over the last 10,000 years (the end of the Younger Dryas Event).

Earth Science Stories

Science Daily, January 21st ... the Kimmeridge Clay deposit is a well known geological formation that runs across middle England - only surfacing at a few points that have been worn down by glaciation but underlying a great swathe of later geological formations. It was deposited in the Late Jurassic between 160 and 145 million years ago and is the main oil source rock in the North Sea. Within the Kimmeridge Clay (which can be seen on Dorset's Jurassic coast and in various quarries) there are divisions, one of which contains many fossils and the other which has none.

Post YD History

Associated Press 29th November 2009 ... the geography department of Northern Michigan University has spent three years on the shoreline of Lake Superior and have been able to define the boundaries as they existed around 2500BC. They found the water at that time was 30 to 40 feet higher than it is today and had features such as shallow water lagoons and enbayments rich in fish and plants.
