A massive ocean circulation that carries heat across the world and helps govern weather patterns in the North Atlantic appears to be slowing down. In fact, according to new studies, it is at its lowest point in the previous 1,000 years.
Recurring outbreaks of crown-of-thorns starfish (COTS) severely damage healthy corals, especially in the Western Pacific Ocean. To obtain a better understanding of population genetics of COTS and historical colonization across the Pacific Ocean, complete mitochondrial genomes were sequenced from 243 individuals collected in 11 reef regions. Our results indicate that Pacific COTS (Acanthaster cf. solaris) comprise two major clades, an East-Central Pacific (ECP) clade and a Pan-Pacific (PP) clade, separation of which was supported by high bootstrap value. The ECP clade consists of COTS from Fren...
How important it is to gaap more knowledge to better understand the process of those oceans that will again influence life on our planet. >> reporter: a region oceanographer is hoping to lead government ocean scientists industry and volunteers in a mission to map the world's sea bed by 2030. >> the shape of the sea bed and how deep it is and the ocean currents, and all influences to a great extent how climate will develop and how climate will change. therefore, if we let parts of the only if on which these climate images are based, our planet models are not as good as they could be. >> reporte...
Who has finally been in touch with herfamily in who has finally been in touch with her family in tonga. scientists have calculated the amount of meltwater dumped by the world's biggest iceberg. the a68 broke away from the antartic coastline in 2017, at one point releasing 1.5 trillion litres of fresh water into the ocean every day. that's nearly eight times the daily water consumption of the united states. researchers say the iceberg will have altered ocean currents in the south atlantic as it melted, and the dust it deposited will have boosted the production of plankton. a previously unknown ...
Knowledge to better understand the processes of those oceans that will, again, influence life on our planet. >> reporter: norwegian oceanographer evert is hoping to reed a network of government, scientists and volunteers in a mission to map the world's seabed by 2030. >> the shape of the seabed and how deep it is and the ocean currents all influences to a great extent how climate will develop and how climate will change. therefore, if we elect parts of the knowledge on which these climate models are based, our climate models are not as good as they could be. >> it also depends where the curren...
