Saving the Tijuana Estuary

submitted by: ucsandiego

The estuary stands as the last barrier between the Pacific Ocean and pollution. Its mix of plants and silt acts as a filter that purifies inland rain and flood waters before they reach the ocean. The beaches of Imperial Beach are closed about 180 days every year. Without the estuary, they would be closed year round.

The Beach of the Future

Building upon a legacy of coastal science at Scripps, high-tech tools are opening new avenues for researchers to track sand movements and further explain beach systems.

Welcome to the New Normal

Scripps Oceanography research suggests that climate change will require a complete rethinking of water delivery systems in the West. That'll be step one.

Ice Drillers are Hard Core

submitted by: ppza
Deciphering the secrets of past climate hidden in ice cores depends on the technical skills and ingenuity under pressure of drillers from ICDS, the University of Wisconsin-Madison's Ice Coring and Drilling Services. In this video, ICDS staffers Lou, Mike and Jay explain why they enjoy the life of drillers, braving extreme cold in some of the remotest regions of the globe. Mike says drilling requires both science and art, and why he keeps his hand on the cable even when it's minus 20; Lou...

Earth's Outlook from Above

Fifty years after Sputnik, satellites peering down on Earth have become valuable scientific tools to study the global environment and offer much needed insight into the future of our planet.

586 Million Year Cycle in Geology Matches Galactic Super-Cluster Spacings

submitted by: RayTomes
The longest geological cycle identified is described as about 600 million years in "Megacycles", the proceedings of a geological conference, Edited by G Williams. However Prof S Afanasiev of Moscow has determined the cycle very accurately to be 586.24 million years using his Nanocycles Method. It so happens that cosmologists, Broadhurst, T.J., Ellis, R.S., Koo, D.C. & Szalay (Nature 343, p 726) have observed regular mega-walls of galaxies at spacings that they describe as 128 Mpc/h,...
