Reykjavik, Keflavik, Husavik, …
The story goes that Iceland's first settler, Ingólfur Arnarson, was the one that named the present capital of Iceland Reykjavík ("Smoky Bay") after the geothermal steam visible in the bay, the steam which today heats homes and outdoor...Show More Summary
Hawaii's Deep Plume
Hotspots in Earth's crust are often considered to be the products of vertical plumes of hot material upwelling from great depths to form surface structures. The Hawaiian islands are probably the most commonly cited example, and indeed...Show More Summary
10 Greatest Discoveries (Within Geology)
These may be the ten most important discoveries within geology: The Earth has a core. Richard Oldham in 1906. Continental Drift. Alfred Wegener in 1911. Sea-Floor Spreading. Harry Hess in 1960. Plate Tectonics. Magnetic Field Reversal. Show More Summary
Grimsvötn Eruption May 2011
At approximately 17:30 Universal and local time on 21 May 2011 the Grímsvötn volcano on Iceland began to erupt. The volcano sent a plume of ash and steam about 20 km into the atmosphere. The volcano is located under the Vatnajökull.

Denmark to Claim North Pole
According to a leaked draft on a 10-year Arctic strategy, which wasn't supposed to be made public until next month, Danish media say the country plans to claim five sections of continental shelf: four around the Faeroe Islands and one off Greenland, which would include the North pole.

Krokite, New Mineral Found in Meteorite
A new mineral has been found in a carbonaceous chondrite meteorite from North-West Africa. The mineral is named Krokite after Alexander N. Krot, a M?noa researcher known for his achievements in meteoritics. The discovery was announced...Show More Summary
Off Topic – Hospitalised
I am in and out of hospital these days. Just out, next Tuesday in again, for a minor operation. Do not worry – it is nothing life threatening, but still a nuisance. It has, as you may already have noticed, a negative effect on my blogging frequency and probably quality. I hope shortly (in a weeks time or so) to be back to normal. Do keep tuned in.
Monster Waves
For centuries sailors had told of the existence of monster waves up to 30 m high, that could appear without warning in mid-ocean, against the prevailing current and wave direction, and often in perfectly clear weather. Such tales were...Show More Summary
New Norwegian Oil Discovery in Barents Sea
A significant oil discovery in the Norwegian part of the Barents Sea 200 km north of the Norwegian coast may be one of the most important finds on the Norwegian continental shelf in the last ten years. The new discovery in the Skrugard block is believed to contain recoverable reserves of at least 150 to 250 million barrels of oil equivalent. Show More Summary
Thorium Nuclear Power (and no more Fukushima)
Is a nuclear power plant possible with no risk of a meltdown, which creates no weapons-grade by-products, and with waste products that are only radioactive for a mere few hundred years rather than tens of thousands? Probably yes, ifShow More Summary
Libyan Iron Deposit
If you think that Libya has no other important natural resources than oil, gas and gypsum, you may be wrong.
The Wadi ash Shati iron-ore deposit, somewhere in the desert north of Sabha, ca. 500 km south of the Mediterranean coast, is one of the largest iron deposits in the world. Show More Summary
Perigee + Full Moon = Super Full Moon
In the weekend Gadhafi's snipers took advantage of an extraordinary super full moon to kill innocent civilians in Benghazi - what an abuse of an otherwise beautiful sight.
On 19 March 2011 the full moon brightened the night sky as the biggest full moon seen for about 18 years. Show More Summary
Libyan Dry Desert Dust
When I find my car covered by a layer of red dust I tell myself “Oh, that is sand from Sahara, brought to us by a wind usually called Sirocco.”
A special variant of the Sirocco is the Ghibli, a hot and dusty wind descending from the interior highlands of Libya toward the Mediterranean Sea. Show More Summary
Desert Divides Libya
The desert is not getting the attention it deserves. It is an important aspect in the present situation in Libya. Some of the pictures that we get from the frontline do however clearly show that most of the fighting now is going on along a road on a bleak desert coast.
Most of Libya is covered by desert. Show More Summary
Mediterranean Sea Level
I have once read a book about Sea-Level Change, but not the book “Cambio Climático en el Mediterráneo Español” (Climate Change in the Spanish Mediterranean). If I had, I would probably have been less puzzled by the news about its second edition brought by EurekAlert. Show More Summary
Marshall Islands Flooded
Last weekend extreme high tides flooded parts of the low-lying Marshall Islands capital Majuro, and several areas of the city were flooded. Flooding of the Marshall Islands atolls, many of which rise less than a metre above sea level, will increase in frequency and magnitude in the coming years. Show More Summary
Evolution of Oxygen Depletion in the Baltic Sea
Although oxygen depletion in the Baltic Sea was much wider spread one thousand years ago than it is today, all is not well. Before you shout with joy over the “improvement”, please notice that we had a relatively warm period - the Medieval...Show More Summary
Greenland-Scotland Ridge - Past & Present
This is a comparison of the situation now and 3 million years ago
Now
At the northern end of the Atlantic Ocean the Greenland-Scotland Ridge stretches from East Greenland to Iceland and the Faroe Islands, and across to Scotland. There...Show More Summary
Extraterrestrial Gold ?
Sometimes I miss an interesting paper because I don’t find the title interesting enough. This actually happened with: “Stochastic Late Accretion to Earth, the Moon, and Mars”, where I thought “so what?”. Now let me add some context to...Show More Summary
Modern lakes and Ancient Oceans
It is paradoxial that you should study modern lakes to learn more about the functioning of ancient oceans. I am referring to lakes like Lake Matano, Sulawesi, Indonesia, and in particular Lake Cadagno in Switzerland. Below the top layer of oxygenated water, Lake Matano's depths are anoxic, free of sulphates, and rich in iron. Show More Summary
