Seeding Atlantic Ocean with Volcanic Iron Did Little to Lower CO2 2013-03-21T17:45:03.610Z Many models have predicted that a warming ocean will take up less carbon because higher temperatures lead to smaller phytoplankton, which take less carbon to the bottom of the ocean when they die. Oceans May Absorb More Carbon Dioxide 2013-03-20T15:15:00.550Z Much of the rest is unattached algae, known as phytoplankton, and tiny animals, known as zooplankton. The Arctic: Tequila sunset 2013-02-07T16:02:59Z There were pieces less than a millimetre across, similar in size to the living things in our sample - the phytoplankton, or tiny plants, and zooplankton, or tiny animals. What are long term threats of plastic in our seas? 2013-01-29T13:15:10Z It remains unclear what the fate of phytoplankton carbon, at the base of the food chain is, however, and the role of iron for fertilising the oceans is a developing field of research. Key to ocean life is widely variable 2013-07-19T20:36:18Z Short-lived effect But the effect was short-lived as the extra iron resulted in the rapid removal of biological nitrate, depriving the phytoplankton of nitrogen they also needed. Seeding Atlantic Ocean with Volcanic Iron Did Little to Lower CO2 2013-03-21T17:45:03.610Z Once phytoplankton and algae were deprived of a needed nutrient, scientists and hydrologists reasoned, the toxic blooms would be a thing of the past. Harmful Algal Blooms Increase as Lake Water Warms 2013-01-08T16:45:09.030Z Algae need light, so must live near the surface—as must the zooplankton and other animals that need the phytoplankton.

But Controversial Fertilization Experiment May Produce Little Science 2012-10-23T17:41:37Z The researchers found that phytoplankton in polar and temperate regions grow best at temperatures higher than the average annual temperatures of the oceans in which they live. Oceans Getting Too Hot to Handle? 2012-10-25T21:40:37Z The scientists observed that the phytoplankton, called Heterosigma akashiwo, swam away from zooplankton, its natural predator, yet remained undaunted by the presence of predators with an appetite for other things. Marine Plant Flees Predators 2012-10-05T10:15:00.170Z In lakes, predator fish keep the smaller fish from eating all the phytoplankton, thus sustaining the lake’s rate of carbon uptake.

Boat turbulence kills zooplankton 2011-04-19T08:32:56Z However, physical drivers such as light supply, nutrient supply, and stratification are known to have an extremely important role on determining phytoplankton chlorophyll – dominating it on seasonal to inter-annual time scales. Dot Earth: On Plankton, Warming and Whiplash 2011-04-26T19:04:43Z These sensitivity analyses revealed that our results are robust and that a long-term decline in phytoplankton is unequivocal.

Ocean-Studying Satellite 'No Longer Recoverable' 2011-03-16T17:23:00Z But these vital annual blooms of phytoplankton are now peaking up to 50 days earlier than they did just 14 years ago, satellite data show. Shifting spring: Arctic plankton blooming up to 50 days earlier now 2011-03-06T23:39:03Z The BAS scientists suggest this means that the bryozoans are now eating for longer, which means they are eating more phytoplankton - the tiny marine plants that draw dissolved CO2 from seawater. Scott samples give climate clues 2011-02-21T17:40:43Z As data from the Ross Sea is analyzed, Asper and his colleagues plan to build computerized models that help them visualize the phytoplankton blooms below the surface.
