Groundwater and climate change revisited: informing adaptation in a warming world
Recent research has identified the natural resilience of groundwater to climate change and our tendency to deplete this invaluable resource. It’s time we understood, valued, and governed groundwater as the vital adaptation to climate change that it is.

Re-thinking watersheds from the bottom up
Despite a few decades of progress on groundwater-surface water interaction and the advent of integrated groundwater-surface water models, it was clear that very different conceptual models of how groundwater fits into the hydrologic cycle were held by different communities within hydrology.

Global Groundwater Sustainability – A Call to Action… do you want to sign?
I am excited about a new initiative called “Global Groundwater Sustainability: A call to action” that was first drafted at the recent Chapman conference in Valencia, Spain. Overall, we are a global group of scientists calling for action to ensure groundwater benefits society now and into the future, and hope that you would like to join us by signing.

Groundwater pumping poses worldwide threat to riverine ecosystems
With the climate strikes happening all over the world, I sometimes wish I had a crystal ball that would allow me to look into the future. Or even better, a crystal ball that could show me different scenarios of what will happen if we change, or not. Well, I do not have a crystal ball, but I do have a global scale hydrological model.

Doing Hydrogeology in R
Use programming languages to interact with, analyze, and visualize data is an increasingly important skill for hydrogeologists to have. Coding-based science makes it easier to process and visualize large amounts of data and increase the reproducibility of your work, both for yourself and others.

Data sharing: an update on new and existing initiatives
Last year, Anne Van Loon wrote about data sharing initiatives in hydrology (“Data drought or data flood?” 28 May 2018). This post gives an update on existing and new initiatives.

Video: Linking water planetary boundaries and UN Sustainable Development Goals
Water Underground creator Tom Gleeson prepared this quick research video (with no more than a toothbrush, a file holder, and a doughnut, in one take!) for the Ripples project meeting at the Stockholm Resilience Centre, that was held in April. In this video, he talks about using doughnut economics for linking water planetary boundaries and UN Sustainable Development Goals.

Have you ever wondered if groundwater is connected to climate?
‘Groundwater-surface water interactions’ has become standard hydrologic lexicon and a perennial favorite session title at various conferences… but how often do you hear the phrase ‘groundwater-climate interactions’?

Celestial groundwater – the subsurface plumbing for extraterrestrial life support
Have you ever taken a walk on the beach during a lowering (ebbing) tide and see mini-rivers grow and create beautiful drainage patterns before your eyes? These short-lived groundwater seepage features are tiny (and fast) analogs of how groundwater has shaped some parts of Mars! It appears that groundwater loosening sediments can lead to all sorts of scales of erosion on both Earth and Mars.

Of Karst! – short episodes about karst
We often associate groundwater with large water storage and very slow water movement, for instance compared to rivers. But is it possible that groundwater flow can be as quick as stream flow? Of karst, it is possible!

First evidence of planet-wide groundwater system on Mars
Mars Express has revealed the first geological evidence of a system of ancient interconnected lakes that once lay deep beneath the Red Planet’s surface, five of which may contain minerals crucial to life.

Water: underground source for billions could take more than a century to respond fully to climate change
While climate change makes dramatic changes to weather and ecosystems on the surface, the impact on the world’s groundwater is likely to be delayed, representing a challenge for future generations.

the true meaning of life for a hydrogeologist….
I stumbled upon this quote from Nelson Henderson (a farmer from Manitoba) which encapsulates what I have been thinking about groundwater sustainability for a number of years…

Unconventional Oil and Gas Development and Groundwater – Comparing the English and Canadian Experiences
The differences between the English and Canadian experiences of unconventional hydrocarbon development were apparent at a meeting co-hosted by the British Geological Survey, Geological Society of London and IAH in London in July 2018.

How deep does groundwater go? Mining (dark) data from the depths
We’ve all been asked (or do the asking), “where does your water come from?” This is a fundamental question for establishing a series of additional questions that can ultimately help define strategies for valuing and protecting a particular water resource.

South Napa Earthquake linked to summer groundwater dip
A summertime expansion in the Earth’s crust caused by changes in groundwater may have triggered the magnitude-6.0 earthquake in California’s wine country in 2014, according to a new study.

A cool new collectible: Water
Post by Matt Herod, Waste and Decommissioning Project Officer for the Canadian Nuclear Safety Commission, and Adjunct Professor in Earth and Environmental Science at the University of Ottawa, in Ottawa, Canada. _______________________________________________ I have always been a mineral and fossil collector. It was a hobby that stuck and blossomed into a career. I still collect minerals and fossils, although I’ve now added rocks from my field sites to the collection. One …

From groundwater flow to groundwater glow: why does groundwater fluoresce in ultraviolet light?
…if we shine ultraviolet light at groundwater samples, then they fluoresce due to the presence of organic molecules that are often present. Unfortunately, we can’t see any of this fluorescence with our eyes, as it is emitted in the middle- and long-range ultraviolet, so we must use detectors that can ‘see’ at these wavelengths.

Bedrock: A hydrogeologist’s devotional
I want to share a book with you that has encouraged me through initial academic mires (I was only in graduate school for 7 years…) and inspired me to expand my perception and appreciation of the natural world.

Groundwater recharge in the American west under climate change
Groundwater recharge in the Western U.S. will change as the climate warms–the dry southern regions will have less and the northern regions will have more, according to new research.
