Robotics has revolutionised ocean observation, allowing for regular high resolution measurements even in remote locations or harsh conditions. But the ice-covered regions remain undersampled, especially the ice-ocean interface, as it is still too risky and complex to pilot instruments in this area. This is why it is exactly the area of interest of the paper …[Read More]
When it comes to climate change, the Arctic and the Antarctic are poles apart. At the north of the planet, temperatures are increasing twice as fast as in the rest of the globe, while warming in Antarctica has been milder. A recent study published in Earth System Dynamics shows that the high elevation of Antarctica …[Read More]
The winter 2016-2017 has been one of the hottest on record in the Arctic. In our Image of the Week, you can see that air temperatures were positive in the middle of the winter! Let’s talk about the reasons and implications of this warm Arctic winter. But first, let’s take a tour in Svalbard, …[Read More]
While the first week of COP22 – the climate talks in Marrakech – is coming to an end, the recent election of Donald Trump as the next President of the United States casts doubt over the fate of the Paris Agreement and more generally the global fight against climate change. In this new political context, …[Read More]
Polar surface water, circumpolar deep water, dense shelf water, North Atlantic deep water, Antarctic bottom water… These names pop in most discussions about the ice-ocean interaction and how this will change in a warming climate, but what do they refer to? In our second “For Dummies” article, we shall give you a brief introduction to …[Read More]
The 30th August 2016 marks 100 years since the successful rescue of all (human) member of Shackleton’s Endurance crew from their temporary camp on Elephant Island (see map). Nearly a year prior to their rescue they were forced to abandon their ship – The Endurance – after it became stuck in thick drifting sea ice, known as …[Read More]
Antarctica is separated from the deep Southern Ocean by a shallow continental shelf. Waters are exchanged between the deep ocean and the shallow shelf, forming the Antarctic cross-shelf circulation: Very dense waters leave the shelf as Antarctic Bottom Water (AABW) that will then flow at the bottom of all oceans. Meanwhile, relatively warm water from …[Read More]
Living Planet Symposium Between the 9th and 13th May, Prague played host to the European Space Agency’s (ESA) fourth Living Planet Symposium. The event, the largest in its history with over 3300 attendees, brought together the earth observation community across multiple disciplines to discuss significant scientific results and the future developments of earth observation missions. …[Read More]
Why? When a river freezes over, it changes the amount of water that flows through the river system. River ice affects many of the world’s largest rivers, and in the Northern Hemisphere, approximately 60% of rivers experience significant seasonal effects. The formation and evolution of river ice changes river discharge and is not only of …[Read More]
Have you ever wondered how results from scientific studies make their way into policy and influence government decisions? Read about the experiences of Sammie Buzzard, University of Reading, who spent her summer working for a government body in Westminster, London, UK. This summer I had the opportunity to take some time away from my usual …[Read More]
