正文(英文) | Guinardia delicatula - a marine diatom, a microscopic plant that can form blooms so large that they can be seen from space. The April bloom formed close to the Cornish coast (arrowed above, left) and spread to the south west. Guinardia is one of the first phytoplankton species to bloom in spring as the recent combination of calm sunny weather and high levels of nutrients following the winter recharge provide ideal conditions for its growth. As the plankton uses nitrates in the water as food to proliferate, the nutrients are rapidly used up and the bloom fades. But not before tiny animals, zooplankton, feast on the plant bounty, themselves providing food for larger animals such as fish; dead cells eventually sink through the water column to provide food for the organisms living on the seabed. Guinardia is thus a key link in coastal food chains at this time of year. |
