Ocean Heat

www.physorg.com March 4th ... a study by Raffaele Ferrari and two students (published by Geophysical Research Letters) has shown that the role of hurricanes has been over-estimated simply because previous studies have not taken into account the seasons. Most of the heat from warm water that hurricanes mix deep into the oceans during the summer and autumn periods is returned to the atmosphere during winter. This indicates that 'warm anomalies' do not affect long term ocean temperature.

K/T Boundary

www.physorg.com March 4th ... the asteroid impact at the K/T boundary left a clear band between light coloured Cretaceous sediments and dark coloured Palaeocene sediments (a picture of the geology is provided online), recovered from the sea floor off South America. The abrupt shift in colour reflects an instantaneous drop in ocean biological productivity. There is also an online video (including an audio interview and animated graph) of the asteroid impact, with Dr Joanna Morgan of Imperial College explaining the science.

Ice Age Florida

http://www.tcpalm.com March 4th ... a local newspaper with a story about human bones found in association with extinct Pleistocene animals - in Florida. Excavations are being organised to unearth more information but provisionally they are assumed to date shortly before the YD boundary event. The discovery was made some 80 years ago during the digging out of a canal. It hit national newspapers at the time but scientists ignored it as they did not believe humans coexisted with mammoths and other beasts of the Pleistocene fauna.

Origin of the Alphabet

Biblical Archaeological Review (www.bib-arch.org ) March/April issue, 2010 ... has an article on the invention of the alphabet by Orly Goldwasser. He begins by outlining the close association of Asiatics from Syria-Palestine with Egypt - from the Old Kingdom through to the Hyksos era. Most of the time it was peaceful and during the Middle Kingdom large numbers of Asiatics were domiciled in Egypt, and many became Egyptianised.

The case for significant numbers of extraterrestrial impacts through the late Holocene

George Howard, on his web site www.cosmictusk.com has posted this 2007 article as it appears to tie in with the latest offering from Bill Napier. 'The case for significant numbers of extraterrestrial impacts through the late Holocene' by Mike Baillie (a speaker at several SIS meetings and events). It can be downloaded in pdf format from the web site - see menu on LH side.

Ocean Vents and El Ninos

www.physorg.com March 3rd ... the Earth Institute at Columbia University has posted evidence of hydrothermal vents on the seafloor near Antarctica. These vents spew volcanically heated seawater from the underwater mountain ranges where lava erupts and new crust forms (mid ocean ridges). Chemicals dissolved in the vents help sustain a complex web of organisms (Geophysical Research Letters).

Utah in Space

www.jpl.nasa.gov March 4th ... planetary scientists have been puzzled for years about the honeycomb patterns and flat valleys with squiggly edges evident from radar images of Saturn's moon, Titan. Now, it is recognised, the terrain is very similar to that of karst topography on earth - in Utah for example, or China and Indonesia (Cassini spacecraft data).

Human Brains

www.physorg.com id186830615 March 3rd ... free will is apparently an illusion. We are simply conscious machines controlled by a combination of our chemistry and external environmental forces. The human brain operates at the conscious level - and the unconscious. It's our conscious mind that makes us aware of our actions and provides us with the sense we control them - yet without the conscious our brains are still capable of inducing our bodies to act.

Thunderbolts

www.thunderbolts.info February 25th ... Mel Acheson claims that during the Ice Age the ice occurred in a ring around the North Pole, quoting Dwardu Cardona and his book, Primordial Star. He correlates such a ring with a ring of aurora. The article doesn't supply any evidence to substantiate this claim or any source that might be checked out - which is unfortunate. Maybe Cardona has references but the thunderbolts article did not.

Asteroid strike at K/T boundary

Science Daily March 1st (www.sciencedaily.com id100301102805) an asteroid strike at the K/T boundary may account for geographic uneveness of the extinctions and recovery according to research by Penn State University geoscientists. At the Cretaceous-Paleogene boundary 93 per cent of nanno plankton became extinct - and these are basic to the ocean food chain. The highest rate of extinction was in the northern hemisphere with decreasing levels in the southern hemisphere.
