To learn about earthquakes, scientists have dug history s deepest ocean hole

Friday, May 28th 2021, 1:43 pm - Drilling took place close to the epicentre the magnitude-9.1 quake that devastated Japan in 2011.
Scientists have just drilled the biggest hole in the ocean ever recorded. It s part of an effort to better understand the history of earthquakes in the Japan Trench, an area where a devastating quake originated in 2011.
On May 14, a team aboard the Kaimei research vessel supporting a project called JFAST used a giant drill to core out a hole off the coast of Japan, reaching all the way to the bottom of the trench, which has a depth of just over 8,000 metres.
Algae blooms becoming more intense, lasting longer in Qu Appelle Valley lakes
Thursday, May 27th 2021, 2:52 pm - We re going to get hit with some wicked . algae if we don t start building policies, advocate says
First Nations leaders, community activists and university scientists say they re growing increasingly worried about the Qu Appelle Valley chain of lakes, with water quality sometimes dipping below recreational use standards and toxic algae blooms increasing in severity. We re going to get hit with some wicked blue-green-purple algae if we don t start building policies and protecting our fresh water, said Aura Lee MacPherson, chair of the Calling Lakes Ecomuseum, an advocacy group that works to protect the Lower Qu Appelle River watershed, in southeastern Saskatchewan.
After months of drought, a soaker of a system nears the Prairies
Digital Writers
Saturday, May 22nd 2021, 7:00 pm - The Victoria Day long weekend might have started off well for most, but showers and strong winds are ahead for the Prairie region as a system draws near from the U.S.
A potent system looks set to slide into the Prairie region to close out the weekend, with effects beginning Sunday morning and lasting through to Monday. Monday features some strong winds from the system, but the bigger impact will be widespread, beneficient rains that will hopefully put a dent in the region s long-standing moisture deficit.
Protected land and ocean jumped 42 per cent in the last decade

Saturday, May 22nd 2021, 6:30 am - Roughly 21 million square kilometres on Earth have been protected or conserved since 2010, but scientists say that s not enough to curb loss of biodiversity.
Land and ocean under protection or conservation increased 42 per cent in the past decade according to a new report. In total, some 21 million square kilometres of protected and conserved areas might seem like a lot, but that has not curbed the continuing loss of biodiversity.
The 2019 Global Assessment Report on Biodiversity found that more than one million of the estimated 8.7 million species on the planet were at risk of extinction due to human activities. The main drivers of species loss include land conversion, deforestation, overfishing, bushmeat hunting and poaching, pollution, invasive alien species, and climate change.
