Credit: Lian Feng A team of Earth scientists affiliated with multiple institutions in China and the U.S. has found that coastal algae blooms (also known as phytoplankton blooms) have been getting bigger over the past couple of decades. In their study, published in the journal Nature, the group analyzed satellite data supplied to them by NASA to compare the…

CLIMATEWIRE | Algal blooms are growing bigger and more frequent worldwide as ocean temperatures rise and circulation patterns change. Climate change is likely one cause of the alterations, which favor the growth of phytoplankton, according to a new study published in Nature. Whether it's good or bad is a murky question. Algae are an important food source for many marine animals, and large blooms can sometimes be a benefit for ocean ecosystems and fisheries. But some algal blooms also release toxins into…

Some of the weather stations there have never recorded any rain in all of their years of operation. However, it’s far from being…

Antarctica isn’t exactly the type of place you’d expect to be teeming with life, but a new study suggests the frigid environment at the end of the world may be a little more hospitable than it seems. Scientists studying sea ice in the region’s Southern Ocean have found evidence of widespread phytoplankton blooms hidden underneath, which appear to be defying an absence of light to thrive in its frosty waters.The findings came as a surprise to the team, led by Dr Christopher Horvat of Brown University and the University of…

The Southern Ocean's vast shelves of floating ice appear to hide sprawling blooms of phytoplankton, a discovery that could significantly change our understanding of Antarctica's marine ecosystem and how it might be impacted by climate change.Key to phytoplankton growth is photosynthesis, and key to photosynthesis is sunlight – and so up to this point experts didn't think there was much opportunity for the plankton to thrive in the dark conditions under Antarctic ice shelves.However, there have been recent discoveries of…

It’s official. Dogecoin’s (DOGE) and Shiba Inu’s (SHIB) good luck is over. After a couple of days of token value rises, the two meme currencies have utterly tanked again. Crypto enthusiasts wished for a hopeful November amid the tumultuous bear market, but by the looks of things, the situation isn’t going to get any easier just yet. The beloved Dogecoin and Shiba Inu, pillars of the meme coin market, faced substantial losses amid the crypto exchange FTX’s near collapse. The FTX Exchange was one of the most widely…

The cryptocurrency arena has undergone several changes in the past nine months, with new projects and developments in the market. Thus, crypto projects need to have clear growth prospects to attract investors. In this regard, Axie Infinity (AXS) and STEPN (GMT) are on the negative side. On the contrary, Chronoly (CRNO) has successfully created a lucrative place for itself. Chronoly’s pre-sale was a success as all its CRNO tokens were sold out on phase 2 and it’s phase 3 closes tomorrow. >>Buy Chronoly…

The fish die-offs, shellfish closures and reluctance among consumers to eat seafood often caused by these blooms costs the U.S. an average of $4.6 billion annually.…
