GeoCinema Online: What a difference technology can make.

Advances in technology mean research that was unthinkable some years ago is now possible. For instance, geographically remote areas which were once out of reach have become more accessible through better (not always easier) transportation, so what we understand by ‘remote areas’ has changed significantly over time. The films in this edition of GeoCinema online are fascinating because they showcase ...[Read More]

Imaggeo on Mondays: A mysterious shrinking lake

From this week’s Imaggeo on Mondays image it’s easy to see why Iceland is the setting of so many books, films and TV shows, inspiring and inciting writers and film crews alike. The picture was taken on the shores of Lake Kleifarvatn, in Reykjanes peninsula, approximately 30 km to the west of the country’s capital, Reykjavík. “The Reykjanes peninsula is unique because it marks theboundary between t ...[Read More]

The known unknowns – the outstanding 49 questions in Earth sciences (Part III)

We continue exploring the biggest conundrums in Earth sciences in this third post of the known unknowns. In the two previous instalments of the series we’ve discovered what the major questions still to be answered about the early days of planet Earth and its inner workings are. We now move onto the planet’s surface. The advent of plate tectonic theory, arguably one of the biggest advancements in t ...[Read More]

Imaggeo on Mondays: Marble outcrops

This week’s Imaggeo on Mondays image was taken by Prof. Konstantinos Kourtidis, in Alykes, along the southern coast of Thassos island, where he photographed the beautifully white marbles that outcrop along the coastline. The Greek Island of Thassos is located in northeastern Greece, close to the coast of Thrace in the Aegean Sea, although geographically it belongs to the Macedonia region. There is ...[Read More]

Imaggeo on Mondays: The Final Effort

We’ve all been there: long hours in the field, a task that seems never ending but which has to be finished today. This week’s Imaggeo on Mondays image is brought to you by Patrick Klenk who highlights the importance of how ‘getting the job done’ relies on good team work! Two years ago I posted this picture to imaggeo as a tribute to everyone who ever experienced the perils and pitfalls of outdoor ...[Read More]

The known unknowns – the outstanding 49 questions in Earth Sciences (Part II)

Here is the second instalment in our series covering the biggest unknowns in the Geosciences. Last week we explored what it is about the Earth’s origin that still remains unclear and this week we probe the Earth’s deep interior. Unlike in Jules Verne’s Journey to the Centre of the Earth, there are no volcanic tubes we can climb down which will allow us to discover the inner workings of our Planet. ...[Read More]

GeoCinema Online: Trials and tribulations of field work.

Field work is not without its trials and tribulations, getting there, for instance can be an adventure in itself. Once you arrive you can expect long days, sandwiches for lunch and frustration at losing your way or equipment not working as you expect it to. Despite all of that, one of the primary draws of the geosciences is being able to spend time in the great outdoors. In the fourth instalment o ...[Read More]

Imaggeo on Mondays: Paramo Soil

What lies between 3000m and 4800m above sea level in the mountains of the Andes? A very special place dominated by an exceptional ecosystem: The Páramo. Picture lush grasslands with a unique population of flora and fauna, some of which is found nowhere else on Earth. Páramos stretch from Ecuador to Venezuela, across the Northern Andes and also occur at high elevation in Costa Rica. The climate her ...[Read More]

Geosciences Column: Adapting to acidification, scientists add another piece to the puzzle

In the latest Geosciences Column Sara Mynott sheds light on recent research into how ocean acidification is affecting the California Current Large Marine Ecosystem. The findings, published in Biogeosciences, reveal large differences between the abilities of different animals to adapt and highlight the urgent need to understand the way a greater suite of species are responding… Large Marine Ecosyst ...[Read More]

Imaggeo on Mondays: Trapped air

Can you imagine walking into the depths of an icy, white, long and cavernous channel within a thick glacier? That is exactly what Kay Helfricht did in 2012 to obtain this week’s Imaggeo on Mondays photograph. Tellbreen Glacier is a small glacier (3.5Km long) in the vicinity of the Longyearbyen valley in the Svalbard region of Norway. Despite its limited size, it is an important glacier. One of the ...[Read More]
