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…] “To fix the reef we first need to fix the land – but where do we start?”
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…] “Glacier depth affects plankton blooms off Greenland:”
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…] “A marine phytoplankton virus affects cloud formation”
A seemingly harmless arts and craft material, glitter has been a part of fun Do It Yourself projects, an intricate part of the fashion and makeup world, and an all-around well-loved item for years. Yet beneath all that glitz and glam lies an unfortunate and little-known truth: that glitter is causing serious harm to the environment.
Glitter is known for its tendency to stick to all available surfaces and be … [more…] “Proving Terrible For the Marine Life: Microplastics”
