Using model simulations of the movement of tuna distributions across the tropical Pacific subject to projected ocean changes, the researchers found that without strong mitigation efforts, tuna distributions are likely to shift away from island fishing zones.
This study uses a high‐resolution climate model to investigate how and why marine heatwaves would change for the Australian region. The relative impacts of increases on background ocean temperature and changes to intrinsic temperature variations are compared.
In a new study published in Nature Scientific Reports, a group of oceanographers, atmospheric scientists, ecologists and fisheries experts got together to identify the most severe marine heatwaves over recent decades. The objective was to understand what triggered these events and led to their ultimate demise.
Climate models project that all circulation features of the South Indian Ocean, including the Leeuwin Current and Undercurrent, North and South East Madagascar Currents, transport through the Mozambique Channel and Agulhas Current are projected to weaken significantly in the last half of the 21st century with unchecked greenhouse gas emissions.
The Climate Variability program has seen an extraordinary amount of activity over the past four months with new arrivals, a clutch of thesis submissions, awards, research voyages and a wealth of research.
The past four months have seen a lot of activity around workshops, the continuing submission of research briefs (which allows us to post about the research on social media), plenty of classic traditional media activity and a new social media account.
In this project we will look at one of the two following questions: Do marine heatwaves occur preferentially in certain seasons, and if so why? Do marine heatwaves produce a consistent response in ocean primary production?
Indian Ocean convection caused a powerful planetary wave that led to a drought in South America and a marine heatwave in the South Atlantic that lasted for months.
Nova pesquisa desvendou que a seca severa que ocorreu no sudeste do Brasil no verão de 2013/14 associada a calor extremo tem uma causa comum, um evento climático distante que ocorreu no Oceano Índico. O estudo liderado pela professora da Universidade Federal de Santa Catarina Dra. Regina R. Rodrigues com colaboração de pesquisadores do Centro de Excelência em Extremos Climáticos (CLEX) da Austrália e NOAA dos EUA, sugere que não é a primeira vez que o Oceano Índico levou a...

Un nuevo estudio científico ha demostrado que la secuencia de eventos climáticos en Sudamérica en 2013/14 que incluyó sequía y olas de calor terrestres y marinas se originó a partir de un fenómeno climático en el lado opuesto del mundo –en el Océano Índico. Los resultados del estudio que fueron publicados en Nature Geoscience por un grupo internacional de científicos de la Universidad Federal de Santa Catarina en Brasil, del ARC Centro de Excelencia de Extremos Climáticos en Australia y...
