Imaggeo on Mondays: A prehistoric forest

Imaggeo on Mondays: A prehistoric forest

This stunning vista encompasses the south-western wilderness of Tasmania as seen from the Tahune air walk 60 m above the Huon river valley. In front lies the beginning of a huge UNESCO World Heritage Site, covering almost a fourth of the area of Tasmania. The site mostly consists of a pristine, temperate rainforest of Gondwanan origin that is home to the tallest flowering trees in the world; Eucalyptus spp. reach up to 100 m height in this region.

“I have never tasted the sense of a more remote place than this one. Give me more,” says Vytas Huth, who captured this stunning shot.

Gondwana was a supercontinent, consisting of present day Africa, South America, India, Madagascar, Australia and New Zealand. It formed when the even larger supercontinent of Pangaea broke up 250 million years ago.

Slowly, Gondwana started to break apart too. India tore away first, followed by Africa and then New Zealand. By the end of the Cretaceous, 65 million years ago, only South America, Australia and Antarctica remained joined.  It took a further 20 million years before Australia and Antarctica separated.

By the time Australia started being pulled northwards, the first glaciers were forming on Antarctica, as it began freezing over. Atop the old rocks which made up its bulk, animals and plants of ancient origin, travel northwards with the Land Down Under.

Because India and Africa broke away from the supercontinent so early on, few hallmarks of ancient Gondwana wildlife are left in their present biodiversity. In contrast, Australia and Tasmania remained connected to Antarctica and South America much longer and there are clear similarities in species across these continents.

“Fossil evidence suggests that temperate rainforest once extended across Australia, Antarctica, South America and New Zealand around 45 million years ago. Such fossils and the surviving species in Tasmania provide evidence of the ancient link to Gondwana”, reports the Tasmania Parks & Wildlife Service.

Academia is not the only route: exploring alternative career options for Earth scientists

Academia is not the only route: exploring alternative career options for Earth scientists

With more PhD and postdoc positions than there are tenured posts, landing a permanent job in academia is increasingly challenging. For some, years of funding and position uncertainty, coupled with having to relocate regularly is an unwelcome prospect. A changing job market also means that aspiring to the traditional, linear career path might be an unrealistic expectation. Skills acquired by those striving for an academic career (analytical skills, time and project management, persistence – writing a thesis requires it by the bucketload!) are highly valued in other job sectors too.

During a short course at the 2017 General Assembly, a panel of current and former geoscientists discussed their experiences in jobs both inside and outside academia.  They offered tips for how to pursue their careers paths and what skills served them best to get there.

In this blog post we profile each of their jobs and offer some of the highlights from the advice given during the session at the conference.


During the panel discussion Victoria stressed the importance of building a strong professional network, both inside and out of academia.

Victoria O’Connor (Technical Director at Petrotechnical Data Systems)

Victoria gained an undergraduate master degree in geology from the University of Liverpool in 2007. Since then, her career has focused around the oil industry, but has seen twists and turns, which have relied heavily on her building a varied skill set.

For almost six years after graduation, Victoria worked at Rock Deformation Research Ltd (RDR),  a spin out company from the University of Leeds, which was eventually acquired by Schlumberger. She held various roles throughout her time there, eventually becoming Vice President. The role relied heavily on her technical expertise as a structural geologist, as well as people management and organisational skills. In 2013, she moved to The Netherlands to work the Petrel technology team at Shell, where she managed various geoscience software development projects.

Her experience eventually enabled her to set up her own geoscience consulting company which was acquired by the PDS Group, through which she now manages the Geoscience products and services division, leading a 40 strong team of geoscientists and scientific software developers, developing cutting edge technologies for the oil and gas industry in collaboration with various academic institutions. In addition she also holds a visiting researcher position at the University of Leeds where she provides teaching and consultancy support. In addition, she also edits the European region AAPG newsletter.

During the panel discussion, Victoria stressed the importance of building relationships and developing a network of contacts. The benefits of building a strong professional network, both inside and out of academia are far reaching: job opportunities, joint collaborations, career development prospects. In her current role, she is developing technology with academic partners she first met over ten years ago at the University of Leeds.


getting on the career To get on the career ladder make sure you have a well written cover letter and CV, says Philip.

Philip Ball (Strategic Planning and Optimization Team & Geological Specialist [Rifted Margins] at Saudi Aramco)

Philip’s career certainly falls in the windy road category, rather than the linear path. It has involved a number of switches between industry and academic positions which have taken him all over the globe. His positions have always had an oil industry focus. He has lived through a number of market slumps, resulting in redundancies and an uncertain career path at times.

During the panel discussion Philip, highlighted adaptability and flexibility (skills certainly gained during research years) as a key to his success. Landing his first position was partly down to his willingness to be flexible.  In addition to being proactive, publishing, attending conferences and meetings, maintaining a network, never giving up is also critical. For example, he applied three times to Statoil between 2013 and 2015 before he managed to get an interview.

Before progressing onto a PhD, Philip enjoyed a short stint at the British Geological Survey and was a geologist for Arco British Ltd. Since gaining his PhD from Royal Holloway, University of London in 2005, Philip has held a number of positions at oil companies, including StatOil, ConocoPhillips, ONGC Videsh and Saudi Aramco.

His top tips, for getting on the career ladder is to make sure you have a well written cover letter and CV. This is critical whether applying for a student travel grant, research position or a position outside of the academic realm. Also do your research and do not expect chances to come to you. Use and visit the job boards online regularly to find positions in geoscience or other fields.


A career in the publications industry is a popular choice among researchers, like Xenia.

Xenia van Edig (Business Development at Copernicus.org)

Researchers are necessarily familiar with the world of academic publication (for more tips on how journal editors work take a look at this post we published recently), so it is hardly surprising this ends up being the chosen career of many former scientists.

Xenia Van Edig is one such example. Following an undergraduate in geography and PhD  in agricultural sciences at Georg-August-Universität-Göttingen, Xenia took a sidestep into the world of scientific coordination and management before starting her role at Copernicus (publishers of open access journals – including all the EGU publications – and conference organisers).

Project management was a skill set Xenia developed throughout her time as a junior researcher. It has been a pillar stone of her career outside of academia too.


Robert is an example of how a a hobby can become a new career direction.

Robert McSweeney (Science Editor at Carbon Brief)

Robert holds an MEng in mechanical engineering and an MSc in climate change. He worked for eight years as an environmental scientist for Atkins, a global design, engineering and project management firm.

For the past three years he’s been working as a science writer for Carbon Brief  – a website covering the latest developments in climate science, climate policy and energy policy – where he is now science editor. The role relies heavily on Robert’s communications skills, which scientists hone throughout their research career in the form of presentations at conference and to peers.

Robert highlighted how a hobby – in this case, writing – can become a new career direction. He also emphasised that scientists have a lot of opportunities to get involved with communicating their research, and commenting on others’, through blogs, Twitter, and developing extra materials to publish with new papers.


You don’t necessarily have to stick within your original field of expertise

Steven Gibbons (Senior Research Geophysicist at NORSAR)

Perhaps the best hybrid career for a researcher is to be able to continue to investigate, but not necessarily in an academic setting. It’s a nice compromise for those seeking a little more stability than life at traditional research institution might offer. But the notion shouldn’t be viewed with rose tinted glasses either: being an industry/foundation based scientists might mean less independence when it comes to selecting research topics and, often, securing funding is still an important part of the equation.

Nevertheless, it is can be a rewarding career which gives insights into a more commercial mindset and which draws on skills gain throughout academic research years, as Steven Gibbons described during the short course in April.

Crucially, his career trajectory highlights that you don’t necessarily have to stick within your original field of expertise. Steven has a PhD in core geodynamics and the Earth’s magnetic field, but now works as a geophysicist within the programme for Array Seismology and Test-Ban-Treaty Verification at NORSAR.

Steven has an undergraduate and PhD from the University of Leeds and has been working for NORSAR since 2002.

Imaggeo on Mondays: Viñales Valley

Imaggeo on Mondays: Viñales Valley

From last week’s unusual desert landscape to this week’s lush valley in Cuba…

The picture shows the Vinales Valley, a karstic depression with mogotes in western Cuba. Karst is the general term for landscapes formed when limestone is disolved by carbonic acid, in rain water. This leads, in particular, to the formation of an underground network of caves and rivers.

In the tropics, due to the heavy rains, the dissolution is fast. The ground collapses above the caves and the karst landscape may evolve to mogotes, which are isolated and steep-sided limestone hills; visible in this week’s featured image. Mogotes can also be found in Eastern Asia, for instance in Halong Bay (Vietnam) or Bohol Island (‘Chocolate Hills’) in the Philipines.

August GeoRoundUp: the best of the Earth sciences from around the web

August GeoRoundUp: the best of the Earth sciences from around the web

Drawing inspiration from popular stories on our social media channels, as well as unique and quirky research news, this monthly column aims to bring you the best of the Earth and planetary sciences from around the web.

Major Stories

On August 25th Hurricane Harvey made landfall along the southern coast of the U.S.A, bringing record breaking rainfall, widespread flooding and a natural disaster on a scale not seen in the country for a long time. In fact, it’s the first time since 2005 a major hurricane has threatened mainland U.S.A. – a record long period.

But Harvey’s story began long before it brought destruction to Texas and Louisiana.

On August 17th,the National Space Agency (NASA) satellite’s first spotted a tropical depression forming off the coast of the Lesser Antilles. From there the storm moved into the eastern Caribbean and was upgraded to Tropical Storm Harvey where it already started dropping very heavy rainfall. By August 21st, it had fragmented into disorganised thunderstorms and was spotted near Honduras, where heavy local rainfall and gusty winds were predicted.

Over the next few days the remnants of the storm travelled westwards towards Nicaragua, Honduras, Belize and the Yucatan Peninsula. Forecasters predicted that, owing to warm waters of the Gulf of Mexico and favorable vertical wind shear, there was a high chance the system could reform once it moved into the Bay of Campeche (in the southern area of the Gulf of Mexico) on August 23rd. By August 24th data acquired with NASA satellites showed Harvey had began to intensify and reorganise. Heavy rainfall was found in the system.

Harvey continued to strengthen as it traveled across the Gulf of Mexico and weather warnings were issued for the central coast of Texas. Citizens were told to expect life-threatening storm surges and freshwater flooding. On August 25th, Harvey was upgraded to a devastating Category 4 hurricane, when sustained wind speeds topped 215 kph.

Since making landfall on Friday and stalling over Texas (Louisiana is also affected) – despite being downgraded to a tropical storm as it weakened – it has broken records of it’s own. “No hurricane, typhoon, or tropical storm, in all of recorded history, has dropped as much water on a single major city as Hurricane Harvey is in the process of doing right now in Houston (Texas)”, reports Forbes. In fact, the National Weather Service had to update the colour charts on their graphics in order to effectively map it. This visualisation maps Harvey’s destructive path through Texas.

So far the death toll is reported to be between 15 to 23 people, with the Houston Police Chief saying 30,000 people are expected to need temporary shelter and 2,000 people in the city had to be rescued by emergency services (figures correct at time of writing).

Many factors contributed toward making Hurricane Harvey so destructive. “The steering currents that would normally lift it out of that region aren’t there,” J. Marshall Shepherd, director of the atmospheric sciences program at the University of Georgia, told the New York Times. The storm surge has blocked much of the drainage which would take rainfall away from inland areas. And while it isn’t possible to say climate change caused the hurricane, “it has contributed to making it worse”, says Michael E Mann. The director of the Earth System Science Center at Pennsylvania State University argues that rising sea levels and ocean water temperatures in the region (brought about by climate change) contributed to greater rainfall and flooding.

While all eyes are on Houston, India, Bangladesh and Nepal are also suffering the consequences of devastating flooding brought about a strong monsoon. The United Nations estimates that 41 million people are affected by the disaster across the three countires. Over 1200 people are reported dead. Authorities are stuggling with the scale of the humanitarian crisis: “Their most urgent concern is to accessing safe water and sanitation facilities,” the UN Office for the Coordination of Humanitarian Affairs (OCHA) said earlier this week, citing national authorities. And its not only people at risk. Indian authorities reported large swathes of a famous wildlife reserve park have been destroyed. In Mumbai, the downpour caused a building to collapse killing 12 people and up to 25 more are feared trapped.Photo galleries give a sense of the scale of the disaster.

What you might have missed

In fact, it’s highly unlikely you missed the coverage of this month’s total solar eclipse over much of Northern America. But on account of it being the second biggest story this month, we felt it couldn’t be left out of the round-up. We particularly like this photo gallery which boasts some spectacular images of the astronomical event.

Since the end of July, wildfires have been raging in southwest Greenland. While small scale fires are not unheard of on the island otherwise known for its thick ice cap and deep fjords, the fires this month are estimated to extend over 1,200 hectares. What started the fires remains unknown, as do the fuel sources and the long-term impacts of the burn.

The U.S.A’s National Oceanic and Atmospheric Administration highlighted that the fires are a source of sooty “black carbon”. As the ash falls on the pristine white ice sheet, it turns the surface black, which can make it melt faster. Greenland police recently reported that unexpected rain haf all but extinguished the massive fires; though the situation continues to be monitored, as smouldering patches run the risk of reigniting the flames.
