 +[[https://​earthdata.nasa.gov/​user-resources/​sensing-our-planet/​fleeting-phytoplankton |July 2, 2012 -  Fleeting phytoplankton --  Along the Antarctic Peninsula, sea ice and phytoplankton are becoming scarce. ]]
 +
 +Scientists working on the Antarctic Peninsula noticed that over the past several decades, phytoplankton blooms have been on the wane. At the same time, the length of the ice season has shortened by nearly three months. On average, ice along the Peninsula now forms fifty-four days later and melts thirty-one days earlier. The shorter ice season means more sunlight reaches the ocean surface. More sunlight should mean more phytoplankton,​ and consequently,​ a booming ecosystem further up the food chain. But the researchers discovered that was not happening. They began to wonder, was disappearing sea ice to blame for the disappearing plankton? And what happens to the animals that depend on the microscopic creatures?
