Jesse Zondervan’s #GfGDPicks (Nov 2017): How did people in ancient times fare during climate changes? Should we use geoengineering? #SciComm

Each month, Jesse Zondervan picks his favourite posts from geoscience and development blogs/news, relevant to the work and interests of  Geology for Global Development . Here’s a round-up of Jesse’s selections for the past month: How successful were people in the Neolithic and ancient times in adapting to climate change? Two contrasting stories emerged this month: A new study from Past Global Chan ...[Read More]

Robert Emberson: Geomythology – Why understanding cultural traditions of landscape are important for sustainable development

Every culture has myths and legends about their native lands. Before we understood the geological forces that forced up great ranges of mountains or sculpted barren deserts, humans needed an explanation for the scale and majesty of natural phenomena. Stories of deities inhabiting volcanoes, or angry gods shaking the very ground upon which people lived, helped people make sense of disasters when te ...[Read More]

The quest of a numerical modelling hero

The quest of a numerical modelling hero

Numerical modelling is not always a walk in the park. In fact, it resembles a heroic quest more often than not. In this month’s Wit & Wisdom post, Cedric Thieulot, assistant professor at the Mantle dynamics & theoretical geophysics group at Utrecht University in The Netherlands, tells the story of his heroic quest to save the princess from the dragon clear a code from bugs and shows ...[Read More]

So we produced this big pile of GIS data, what now?

We all know that easy access to data speeds up doing research. In this post, we will discuss how open GIS data can stimulate innovative ways of doing research in the field of geodesy and geosciences, considering first the benefits and challenges of open data. Geodesy can benefit greatly from the open data movement and from open Geographic Information System (GIS) data. The reasons for this are two ...[Read More]

Imaggeo on Mondays: Bird’s eye view of Trebecchi Lakes

Among many other environmental impacts, human activities have introduced a range of animal and plant species to areas where they do not naturally belong. The introduction of alien species, as these translocated taxa are known, has wide ranging implications for native biota, ecosystem functioning, human health and the economy. Research published earlier this year found that during the last 200 year ...[Read More]

Image of the Week — Climate change and disappearing ice

The first week of the Climate Change summit in Bonn (COP 23  for those in the know) has been marked by Syria’s decision to sign the Paris Accord, the international agreement that aims at tackling climate change. This decision means that the United States would become the only country outside the agreement if it were to complete the withdrawal process vowed by President Trump. In this context ...[Read More]

GeoSciences Column: The dirty business of shipping goods by sea

November 10, 2017
“Above the foggy strip, this white arch was shining, covering one third of the visible sky in the direction of the ship's bow,” he explains. “It was a so-called white, or fog rainbow, which appears on the fog droplets, which are much smaller then rain droplets and cause different optic effects, which is a reason of its white colour.”

Shipping goods across the oceans is cost-effective and super-efficient; that’s why over 80% of world trade is carried by sea (according to the International Maritime Organisation). But the shipping industry also contributes significant amounts of air pollutants to marine and coastal environments. A new study, published in the EGU’s open access journal Earth System Dynamics, reports on concentratio ...[Read More]

Community advice to young hydrologists, Part 1

We at Water Underground loved reading Young Hydrologic Society’s post titled “Community advice to young hydrologists” – an advice column written by a network of established scientists in the field. We appreciated the column so much, in fact, that we have decided to re-blog the post to you (with YHS’s consent, of course). We’ve split up their post by question, and have added in hyperlinks to all co ...[Read More]

Heather Britton: Sinkhole Occurrence and Mitigation

Sinkholes are often overlooked geohazards which, although far less destructive in the short-term than earthquakes and landslides, can be catastrophic to life and severely impact the built environment. This post will explore how these features form and the strategies that have been adopted to predict their appearance. It will also consider how urbanisation in karstic areas is accelerating sinkhole ...[Read More]
