Rivers deliver sediment from land to the ocean. This sediment contains nutrients which can feed microscopic algae in water. But, if there is too much sediment and nutrients, delivered by floods from land-based erosion, algal blooms can occur that have negative effects on the Great Barrier Reef.
The challenge is that sediment comes from many different locations and we need to know … [more…]
Study shows complex connection between meltwater discharge and nutrient input — ScienceDaily
Summary: The unusual timing of highly-productive summer plankton blooms off Greenland indicates a connection between increasing amounts of meltwater and nutrients in these coastal waters. Researchers now show that this connection exists, but is much more complex than widely supposed. Whether increasing meltwater has a positive or negative effect on summertime phytoplankton depends on the depth at which … [more…]
Photo: the phytoplankton species Emiliana huxleyi, coming soon to a cloud near you.
A species of marine phytoplankton that explodes after contracting a virus may play a role in regulating Earth’s climate, a new study finds.
Emiliania huxleyi is a type of single-celled plant-like organism called a coccolithophore that occurs ubiquitously in the world’s oceans. Under the right conditions, it multiplies rapidly to form giant aggregations, known as blooms, up … [more…]
