The Australian bushfires of the 2019/2020 summer had far-reaching effects. It has now been revealed in new research published in Nature that the smoke produced a phytoplankton bloom larger in area than all of Australia, thousands of kilometres away in the Southern Ocean between New Zealand and South America.
This study looks at 6 months of under-ice zooplankton observations from the N-ICE2015 expedition from January to June 2015 in the Eurasian sector of the Arctic Ocean north of Svalbard.
It has been remarkable how much we have achieved in this extraordinarily difficult year. Research coming out of the Teleconnections and Variability program over the past four months has strongly focused on how influences in one part of the world can have direct impacts on another.

In this paper, the researchers investigated how a major glacier tongue break in the Mertz polynya in Antarctica impacted phytoplankton blooms. Larger phytoplankton blooms increase the amount of carbon that can be stored in the deep ocean.
Tiny microbes at the base of the ocean food chain will be increasingly affected by marine heatwaves as the climate changes.
CLEX researchers evaluate the performance of satellite chlorophyll observations in the tropical Pacific Ocean and suggest algorithm improvements.
In this project, the selected student will use a one-dimensional numerical ocean model to simulate and understand the physical and biogeochemical processes in the ocean near Australia. The student will utilise the long-term oceanographic measurements conducted at one of the National Reference Stations maintained by the Australian Integrated Marine Observing System (i.e., the Maria Island, the Port Hacking, and the Rottnest Island).
Joan Llort Jordi (IMAS) Farewell Seminar: Decadal changes in Tasman Sea phytoplankton induced by atmospheric dust
The study finds important regional consequences for precipitation and clouds formation if large changes in dimethyl-sulfide emissions were to occur. In a hypothetical case where all marine DMS emissions cease completely, we find the Earth would warm by approximately 0.5 degrees C over a ten-year period.
