Walking Through Time

Nearly three years ago, two researchers uncovered a series of footprints on a beach in Happisburgh, Norfolk. Preserved for at least 800,000 years beneath layers of sediment, the footprints had been exposed by recent storms. There was just enough time to record 3D images of them before they were swallowed up by the tide.

The prints – around 50 of them, some partial, some complete with the imprints of toes – meandered through what would once have been a river bed. Approximately five individuals, adults and children of both sexes, winding their way south along the mudflats, perhaps searching for seafood.

‘We always think about geological time as being not on a human scale’ says Dr Tori Herridge, presenter of ‘Walking Through Time’ (Channel 4, Saturday 6th February, 8 pm), which opens with a closer look at the Happisburgh prints. ‘Which is true – but there are moments which are real, and leave their mark.

‘You get stopped in your tracks, because you think of geology as slow moving, but what we’re actually capturing when we uncover evidence like this are moments. In this case, a few individuals walking along a river bank. Footprints buried and eroded out, visible for a brief moment before they’re washed away.’

At the time the prints were made, Britain was not an island but a peninsula of Europe, joined by a land bridge to France. It is thought that the individuals who made them were migrants, adapting themselves to the colder northern climate. Theirs are the earliest known human footprints outside of Africa.

Megaflood

Another moment in geological time – the catastrophic flooding which erased that land bridge – is the subject of ‘Walking Through Time’, which airs this Saturday. Thought to have taken place 450,000 years ago, the massive inundation changed the course of Britain’s history, isolating it from Europe. By visiting sites around the country, Herridge explores how Britain changed before and after the megaflood, and examines the evidence for how and when it happened.

‘After that, everything changes’ she says. But the event itself would have been relatively, geologically speaking, brief.

‘It would have involved huge volumes of water – unimaginable volumes. Hundreds of times the power of Niagra Falls, pouring over the ridge between Calais and Dover. That kind of event, the scale of it, is rarely seen in human history, but it would have been momentary. Perhaps a matter of weeks or months.’

The evidence for this flooding event is largely unseen – canyons and river channels beneath the English Channel, punctuated by tear drop shaped islands. Recent research by Jenny Collier, who features in the programme, demonstrates that these island structures were carved from the bedrock, suggesting massive flooding was the cause.

As well as research by professional scientists, Herridge hopes the programme will highlight the important work carried out by amateur researchers.

‘We make a deliberate attempt not to separate the two. We’ve avoided scenes set in laboratories – the programme is about fieldwork, and making discoveries yourself. This is what makes geology fun – the camaraderie, the accessibility.’

Among Herridge’s interviewees is Margaret Hems, discoverer with her husband of the West Runton Mammoth. The Hems were skilled amateur palaeontologists, who searched their local area following stormy weather, looking for fossils. The large bone they discovered in December 1990 turned out to be the start of a major three month excavation, uncovering an 85% complete specimen.

Like the Happisburgh footprints, the mammoth is evidence of Britain’s pre-island past. Like the footprints, it was uncovered on the Norfolk coast following storms and, like the footprints, it preserves a moment in time. A male steppe mammoth in its prime, succumbing to a leg injury around 700,000 years ago and preserved beneath layers of sediment – but not before its body had been scavenged by hyenas, evidence of which were also discovered at the site.

‘Discoveries like this help us understand how relevant geology is today’ says Herridge. ‘We shouldn’t separate ourselves from the geological present. We shouldn’t forget that features which seem permanent aren’t – things can change in an instant, and have a lasting effect.

‘I hope that, after seeing the programme, when people next go out walking and hiking and look around them, they realise they can join in themselves. There are beautiful places in Britain you can visit, which hold fascinating secrets about our past.’

2016: The Year of Water

YEAR OF WATER GREEN 460x148px for web final

 

 

 

 

Following our inaugural themed Year of Mud, the Society has declared 2016 to be the Year of Water!

Throughout 2016, we’ll be exploring the different and varied ways in which geology and water interact, and the importance of these links to people and the environment.

‘The importance of water to geological processes cannot be overstated’ says GSL President David Manning. ‘Whether as ice, liquid or gas, water is essential to many areas of our science -rock forming processes, understanding and use of groundwater, glaciation, ocean chemistry, palaeoclimatology, living with geological hazards – the list goes on!’

David Jones, Vice President of the Geological Society and a hydrogeologist at Natural Resources Wales says ‘Following the devastating floods we’ve seen so far this winter, and those in the winter of 2013/14, a longer term view of managing river and groundwater flooding is imperative.

‘A good understanding of hydrogeology and the behaviour of the subsurface, in the context of the increasing challenges of climate change, will be essential in managing these hazards.’

Important links between geology, water development and sustainability also underpin several of the recently announced UN Sustainable Development Goals, and discussions at the recent COP 21 summit in Paris.

Water will be at the heart of the our science programme throughout 2016, through a variety of research conferences, lectures, educational activities and other events.

Topics will include tsunamis, groundwater and water on Mars, as well as a broad overview of water and the myriad ways it plays an essential role in processes throughout the Universe. Upcoming events include a public lecture by ITV Science Correspondent Alok Jha, author of ‘The Water Book’, and a conference focusing on Martian gullies and their Earth analogues.

‘The Year of Water will provide an opportunity to share and debate emerging research, as well as to communicate with policy makers and the wider public’ says Professor Manning. ‘We hope to highlight the vital role of water in understanding how our planet works, and how we can live sustainably on it.’

New Documentary: Nature’s Wonderlands

Former President, author and palaeontologist Richard Fortey’s new BBC 4 documentary is kicking off tonight!

‘Nature’s Wonderlands: Islands of Evolution’ investigates why islands are natural laboratories of evolution and meets some of the remarkable and unique species that live on them.

Episode one, which travels to Hawaii to investigate how life colonises a newly born island, starts at 9pm this evening.

Though we don’t have a sneak preview for you, we do have this evidence of Professor Fortey meeting one of those remarkable species…

While the rest of us are working on making, breaking and conveniently overlooking newly made resolutions, some in the geological community are focusing on a more fundamental resolution. It’s a subject which has been under discussion for several years, and the topic of countless meetings, articles and debates.

Now, the Anthropocene Working Group has started the year by publishing a report  on the question which has been splitting the geological community – has the human race, by our own agency, established a new geological time period? Their answer – though not the final word – is a resounding yes. Continue reading
