News from Earth's magnetic field

December 21, 2007

It is widely known that the geomagnetic field shields our planet against highly energetic cosmic particles. The importance of the magnetic field for answering geological, tectonic or even archaeological questions is less known. Where do large, very old meteorite craters exist like, for example, the one that might have led to the extinction of the dinosaurs? How did the continents move about the globe through geological times? How does the hidden subterranean structure of a volcano look like, i.e. how high is the danger of eruption" Where had towns and buildings of ancient civilizations been located, which have long since been destroyed?

The study of anomalies of the magnetic field of the Earth's crust and upper mantle can provide significant indications to answer such questions. Detailed global mapping of magnetic anomalies has only recently become possible by integrating huge amount of data from different platforms. Mioara Mandea of GeoForschungsZentrum Potsdam (GFZ) and Erwan Thébault of Institut de Physique du Globe de Paris (IPGP) have compiled an overview over the Earth's magnetic field and current research topics on magnetic anomalies in a booklet published in cooperation with UNESCO by the Commission for the Geological Map of the World (CGMW, Paris).




"This summarized state of knowledge is based on current observations, models and interpretations of the Earth's magnetic field and also makes clear that many aspects of the field will remain future topics of research. The Swarm satellite mission planned for 2010 will serve this purpose," says Professor Reinhard Hüttl, chair of the GFZ executive board.

The booklet also is a complement to the recently published World Digital Magnetic Anomaly Map. This is the first global compilation of all available information on magnetic anomalies, based on more than 50 years of data from aeromagnetic and marine surveys, on ground measurements, on high-quality, high-resolution satellite data, like CHAMP of GFZ, and supplemented by values derived from an ocean bottom anomaly model based on crustal ages.

Distortion

Distortion
by Magnetic Fields

Distortion, Magnetic Fields’ second Nonesuch release, features the brilliant melodies and wry lyrics that composer and band leader Stephin Merritt has long been praised for, but, as the album title suggests, he serves them up with a twist. If the late, great Cole Porter had somehow been resurrected just in time to appear at the Coachella indie-rock fest, the results might sound something like this –"small, ironic tales of love and woe," as National Public Radio has described Merritt’s songs, startlingly enveloped in layers of live feedback that recall the noisy pop provocations of legendary Scottish quartet The Jesus and Mary Chain.

As album producer, Merritt takes a completely novel approach to his deployment of feedback, going well beyond mere fuzzed-out guitar to...

by Magnetic Fields

The long-awaited follow-up to the acclaimed 1999 release 69 Love Songs, i finds singer/songwriter Stephin Merritt in full possession of his acerbic wit. Featuring lyrics ripe with melancholy and bittersweet imagery, the record's fourteen tracks are possibly the most personal Merritt has created to date -- a departure from the many voices on 69 Love Songs.

The Charm of the Highway Strip

The Charm of the Highway Strip
by Magnetic Fields

Sweet and sour, incurably romantic, and deeply misanthropic, Magnetic Fields' mastermind Stephin Merritt is a one-of-a-kind voice in modern lo-fi pop. This 1994 outing is a bit of a departure, with Merritt taking his trademark ABBA-styled Casio-pop for a spin in the country--literally. Awash in lush, Nashville-ready production, songs like the doleful "Lonely Highway" (which encompasses snatches of the Lee Hazelwood classic "Jackson") and "Born on a Train" are nothing short of thrilling. But much of this particular stretch of the Fields is lacking in charm, since Merritt's wry stance chafes a bit too hard against the guileless melodies. Completists may feel compelled to take a ride, but novices should probably stick to the more urbane journeys offered by Holiday and Distant Plastic Trees....

Magnetic Field(s)

Magnetic Field(s)
by Ron Loewinsohn (Author)

Organised around the idea that "you can't know what a magnetic field is like unless you're inside of it," Ron Loewinsohn's first novel opens from the disturbing perspective of a burglar in the midst of a robbery, and travels through the thoughts and experiences (both real and imaginary) of a group of characters whose lives are connected both coincidentally and intimately. All of the characters have a common desire to imagine and invent rather horrifying stories about the lives of people around them. As the novel develops, certain phrasings and images recur improbably, drawing the reader into a subtle linguistic game that calls into question the nature of authorship, the ways we inhabit and invade each other's lives, and the shape of fiction itself.
