October 4, 2024 Jeremy Day, _University of Newcastle_ Sharks easily consumed large, spiky sea urchins – sometimes in just a few gulps. See it for yourself, in our new Footage from the Field

Series. May 27, 2024 Albert Pessarrodona Silvestre, _The University of Western Australia_; Karen Filbee-Dexter, _The University of Western Australia_; Mirjam van der Mheen, _The University

of Western Australia_, and Thomas Wernberg, _The University of Western Australia_ Underwater rivers ferry large volumes of seaweed from shallow seas into the deep, where its carbon is stored

naturally April 10, 2024 Samuel Starko, _The University of Western Australia_; Brian Timmer; Christopher Neufeld, _University of British Columbia_, and Julia K. Baum, _University of

Victoria_ Kelp forests around the world, and in Canada, are under threat. New research sheds further light on the health, and resilience, of these crucial ecosystems. March 25, 2024

Catherine Wilding, _Marine Biological Association_ and Hannah Earp, _Newcastle University_ Kelp seaweed spores are being grown on small rocks and waste scallop shells as part of a trial

exploring how to regenerate the UK’s coastal kelp forests. January 21, 2024 Tim Flannery, _The University of Melbourne_ To fight global warming we will soon have to try to remove carbon

dioxide from the skies or find ways to reflect the Sun’s heat. Such radical paths must be examined, but risky experiments avoided. November 3, 2023 John Keane, _University of Tasmania_ and

Scott Ling, _University of Tasmania_ Controlling invasive sea urchins is expensive. Why not make it profitable by fishing for them and selling their roe as a delicacy? July 11, 2023 Reina

Veenhof, _Southern Cross University_; Curtis Champion, _Southern Cross University_; Melinda Coleman, _The University of Western Australia_, and Symon Dworjanyn, _Southern Cross University_

New findings suggest animal-mediated plant reproduction might have originated in the ocean. April 18, 2023 Aaron Eger, _UNSW Sydney_ We cannot afford to ignore kelp – these vibrant

underwater forests have sustained people and ecosystems for centuries, and continue to do so today. March 30, 2023 Aaron Eger, _UNSW Sydney_ and Adriana Vergés, _UNSW Sydney_ When we stopped

whaling, the whales recovered. But our vital kelp forests won’t return without our help February 1, 2023 Peter de Menocal, _Woods Hole Oceanographic Institution_ The ocean twilight zone

could store vast amounts of carbon captured from the atmosphere, but first we need a 4D monitoring system to ensure ramping up carbon storage does no harm. December 6, 2022 Neil Andrew,

_University of Wollongong_ A solution for managing the growing populations of long-spined sea urchins may not be clear at the moment, but there is a path forward. September 15, 2022 Albert

Pessarrodona Silvestre, _The University of Western Australia_; Karen Filbee-Dexter, _The University of Western Australia_, and Thomas Wernberg, _The University of Western Australia_ Our

ocean forests of seaweed are enormous. But these quick-growing, life-supporting forests are already vanishing. March 11, 2022 John Barry Gallagher, _University of Tasmania_ Seaweed was

thought to be a vital tool in the fight to slow climate change. But it turns out seaweed ecosystems may be a natural source of carbon dioxide – and not a sink. October 26, 2021 Alistair

Hobday, _CSIRO_; Dan Smale, _Marine Biological Association_; Kathryn Smith, _Marine Biological Association_, and Thomas Wernberg, _The University of Western Australia_ The indirect losses

from one heatwave in Western Australia caused A$4.14 billion per year worth of damage. April 1, 2021 Diane Kim, _USC Dornsife College of Letters, Arts and Sciences_; Ignacio Navarrete, _USC

underwater Arctic kelp forests are proliferating, and might be a potential resource. March 4, 2019 Dan Smale, _Marine Biological Association_ and Thomas Wernberg, _The University of Western

Australia_ Marine heatwaves, like their land counterparts, are growing hotter and longer. Sea species in southeastern Australia, southeast Asia, northwestern Africa, Europe and eastern

Canada are most at risk. July 16, 2018 Adele Morrison, _Australian National University_; Andy Hogg, _Australian National University_; Ceridwen Fraser, _Australian National University_, and

Erik van Sebille, _Utrecht University_ A chance discovery of some kelp that floated for 20,000km before washing up on an Antarctic beach has opened up a new chapter in our understanding of

the currents that swirl around the Southern Ocean.
