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 how progress in science know-how mean the advancement of our understanding of planet Earth.

A planetary perspective with Landsat and Google Earth engine

Since July 1972, NASA’s Landsat satellites have gathered images over the entire land surface of the Earth. These images, archived at USGS, reveal dynamic changes over time due to human activity (deforestation, urbanization) and natural processes (volcanic eruptions, wildfire). Now, Google Earth Engine allows scientists, researchers and the public to easily view and analyse this treasure trove of planetary data.

Down to the volcano

A team of scientists have set themselves the goal of building an advanced deep ocean laboratory – on the edge of an active submarine volcano, over a mile below the surface. This research certainly pushes the boundaries of what are considered remote areas!

Project Azolla

How a freshwater fern can provide food, feed & biofuel. This video presents the potential of aquatic farming with a special plant: the fresh-water fern Azolla. The new technology showcased in this video highlights how Azolla provides an innovative way of sustainable, renewable farming.

 

Have you experienced the trials and tribulations of field work? You aren’t alone! As showcased in our last GeoCinema post. If you missed any of the series so far why not catch up here?

Stay tuned to the blog for more films!
