The Future of Critical Zone Science: Call for Papers

This entry was posted in Science on by .

Critical zones and watersheds are ‘human habitats,’ important for sustaining basic human needs such as water, food, and energy as well as providing crucial ecosystem services. To safeguard these interests, several long-term critical zone (CZ) observatories and watershed sites have been established throughout the world, including in Canada, China, France, Germany, the United Kingdom, and the United States.

While these CZ observatories and watershed sites may vary in their specific design, regional setting, or high priority science questions, a common feature is that they each provide a multi-faceted and multidisciplinary approach to observation of the Earth’s surface throughout the extent of the critical zone.

Let’s take as a starting point that ‘the Earth is moving yet again.’ It is shifting, unstable, reactive; it’s different one year, or minute, to the next. In an age of rising seas and mass extinctions, the point hardly needs proving.

Two of the Most Destructive Forces of Nature ‘ Earthquakes and Tsunamis ‘ May Be a Bigger Threat Than Thought

The researchers developed a new method to assess earthquake and tsunami hazards represented by the most distant part of offshore subduction zones and found that the hazard might have been systematically underestimated in some areas, meaning that tsunami risk assessments should be redone given the new results. The findings have important implications for the mitigation of risk in affected areas worldwide, including Southeast Asia and the Pacific Rim, in the event of future earthquakes and tsunamis.

Megathrust earthquakes are among the most powerful earthquakes experienced worldwide and occur in subduction zones, where two tectonic plates converge, and one slides under the other. The plates move toward each other continuously, but if the interface, or fault, between them is stuck, then a slip deficit builds up over time. Like a debt, this slip deficit has to be paid off eventually, and for tectonic plates pay day is earthquake day. When these earthquakes affect the shallowest part of the fault near the seafloor, they have the potential to shift the seafloor upward and create devastating tsunamis as well.

California Tribes Call Out Degradation of Clear Lake

Formed some 2 million years ago at the intersection of three geologic faults, Clear Lake is a natural marvel, considered the oldest lake in North America. It is also the site of severe blooms of toxic cyanobacteria from June through November that obscure the water and are a risk to health and safety. Photo ‘ Brett Walton/Circle of Blue

What are the nine boundaries humanity must respect to keep the planet habitable?

But over the past two centuries, humanity has dramatically increased greenhouse gas concentrations in the atmosphere, pushing us outside this ‘safe’ climate zone; outside the conditions for which civilisation has been designed.

Unfortunately for us, climate change represents just one of nine critical planetary boundaries, which the imprudent actions of our species risk dangerously destabilising and overshooting.

Together, the stability of these nine processes is essential to maintaining the Earth’s atmosphere, oceans and ecosystems in the delicate balance that has allowed human civilisations to flourish. However, these are also the processes that human activities have impacted most profoundly.
