Survivors: Nature’s indestructible creatures

An ex – President of the Geological Society is bound to be one of the survivors. But starting on Tuesday 24th at 9  p.m. I am fronting a BBC4 series about different kinds of survivors – animals and plants whose relatives are known deep in the fossil record.

“Living fossils” was how Charles Darwin described them. It is a label that has stuck, although we now know that even if their morphology has not changed much, interesting things might still be happening at the genetic level.

Based on my new book “Survivors” (Harper Press) the series is a dash around the world to look for some of the animals and plants that time has passed by. If there are secrets to longevity, it would be good to know what they are.

The journey took the crew and the author (twice their age) to watch horseshoe crabs spawning on Delaware Bay, to the hot springs of Yellowstone National Park  (in a blizzard), to Kangaroo Island to search out echidnas, and to Henley on Thames to find liverworts. It was a fine distraction for one who has spent most of his life looking at trilobites.

Don’t forget to tune in tomorrow night, and let me know what you thought in the comments below.

Geology with added microbes

One of the fastest growing areas of research in the geosciences is what is now called ‘geomicrobiology’. Although bacteria and other microbes have long been used in industrial processes such as bioleaching, where  metals are extracted from their mined ores, it is only now that the role played by microbes in geological processes is being fully appreciated. At and near Earth’s surface, such organisms can be involved in electron transfer reactions that have a great impact on the chemistry of sediments, soils and waters, influencing the cycling of major elements such as sulphur and iron, and of trace toxic elements such as arsenic.

Top five youtube geology clips – and other ways to spend the Christmas holiday…

A rock that looks like Santa Claus - what could be more festive?! (c. JoEtta Abo)

As well as eating and drinking, Christmas is traditionally a time for doing very little. In celebration of this, we’ve compiled a few geological ways to pass the time during the holiday. Continue reading

All in a whorl

We knew we were in for it when we chose a picture library image of an unidentified ammonite for the cover of the November issue of Geoscientist.  So far reactions have been of two kinds – compliments on the graphic design, and complaints regarding the lack of diagnosis.  So, hoping to move on beyond the commercial photolibrary’s rather unhelpful “Fossil 9857643”, we asked around. Continue reading

Farewell to the Antarctic

There has been some rough weather in our last few days – it comes as a surprise when the horizontal surface you’re standing on suddenly has the gradient of one in three! But this is pretty good for the Furious Fifties. It can get much, much worse.

We have discovered our cabin window leaks as the spray washes over the ship. The drip tray beneath the window builds up a few inches of water, then, with just the right amount of roll building up a suitable wave, a cascade sloshes onto the bed. Not mine; it was the Alaskan who had the cold shower at 2am…

Christmas gift idea!

Cover, June 2009 Geoscientist (vol 19.6)

Back in 2009, the cover of Geoscientist carried an image scanned from a fragment of Paesina Stone from Tuscany – a silty limestone formed during the Cretaceous Period and marked with a fine network of cracks through which groundwater has diffused, bringing colourful oxides of various minerals.  This stunning image had been created by Richard Weston, professor of Architecture at Cardiff University.  Continue reading

Communicating geology in the digital age

When the news broke on Friday that a new Icelandic eruption could be on the way, it didn’t take long for it to spread.

This hasn’t always been the case. In its early years, the physics of geological communication was simple – involving nothing more than oscillations of pressure transmitted through a gas – talking. Continue reading
