Visualising algae-eating viruses from space

Posted by in categories: biological, climatology, sustainability

Algae isn’t just found in your garden pond or local river. Sometimes it explodes into vast “blooms” far out to sea, that can be the size of a small country. Such algal blooms can match even a rainforest at taking carbon out of the air. And then, in just a week or two, they are gone – sometimes consumed by viruses.

Given the scale of blooms and their vital role in both marine ecology and climate regulation we must know more about these viruses. Research conducted with our Weizmann Institute colleague Yoav Lehahn and others and published in the journal Current Biology, is the first attempt to quantify the affect of viruses on large scale algal blooms.

Algae in this context refers to tiny sea organisms known as phytoplankton which exist right at the bottom of the marine food web, providing the ultimate source of all organic matter in the sea. They do this by consuming carbon dioxide during photosynthesis, “fixing” this carbon into organic matter (themselves) in the same way trees take carbon out of the air.

Algae Water Purification

Posted by in categories: biological, climatology, sustainability

This can be good to purify the oceans and lakes.


Grow algae to reclaim water! Algae feed on the nutrients in wastewater, effectively purifying the water and producing oxygen during the process. Sunlight and LED lighting help the organisms to feed and grow, therefore our algae generators stand in the daylight filled Third Climate Zone. Water slowly recirculates through the six algae tubes, each of which has a steel base containing zeolite, a mineral that acts as a microbial filter, absorbing microorganisms that are not otherwise digested by the algae. The algae generators at Green Solution House are an important element of our on-site biological water purification system. The entire system can process 500 liters of water a day, which is used for irrigating the green wall and gardens and has the potential to be used for flushing public toilets in the building. The water cleaned by the algae is separated and further purified by UV light to reach drinking water quality.

Who’s behind it: Rambøll.

That Unusually Large Ozone Hole Over The Arctic Has Closed Up Again

Posted by in categories: climatology, surveillance

Earlier this year, the layer of ozone over the Arctic thinned out enough to be considered a serious sized hole. It wasn’t exactly impressive compared with its southern cousin, but it was certainly a lot bigger than we’d ever seen it before.

Now, according to surveillance by the Copernicus Atmosphere Monitoring Service (CAMS), we can breathe a sigh of relief. It’s healed up again.

That’s great news for ecosystems below, which rely on concentrations of ozone gas high up in the stratosphere to act as a planetary-scale sunscreen against damaging showers of UV radiation.
