Tidal flats, the muddy reaches of estuaries unveiled at low tide, support rich ecosystems and fisheries worldwide. But these habitats are under threat from climate change, as sea level rise overwhelms the landscape and heavy rainfall scours away the sediment – impacts that scientists are only just beginning to explore. In an effort to understand how shellfisheries are affected by climate change, a ...[Read More]
Hello Alessandro. Thank you for joining me for this edition GeoTalk! Could you tell our readers about your background before we dive in? I am an oceanographer based at the University of Southampton (UK). I am interested in polar oceanography and ice-ocean interactions. The focus of my work is to understand the processes that control ocean heat transport toward rapidly-melting Antarctic glaciers. ...[Read More]
This week on 21st June, governments around the world observed World Hydrography Day to celebrate the role of hydrography in understanding the seas. Though initially thought to be a field limited to the navigation of ships, hydrography is being increasingly recognized for its knowledge contribution to the oceans, seas, coastal areas, lakes and rivers, as well as with predicting their change over ti ...[Read More]
Yesterday (8 June) was globally observed as World Oceans Day. The United Nations announced that it is joining forces with decision-makers, indigenous leaders, scientists, private sector executives, civil society, celebrities, and youth activists to put the ocean first. This year’s theme is “Planet Ocean: tides are changing,” to encourage everyone – whether as individuals or groups – to respect the ...[Read More]
“The ocean is not too big to fail, nor is it too big to fix, but it is too important to ignore.” Last week, Dr Jane Lubchenco voiced a thought we’ve all had at some point: that the ocean is so vast and bountiful, it is almost inconceivable that people could impact it. And yet… Speaking to more than 20 Heads of State and Government, and an audience of thousands of policymakers, ocean scientists, bu ...[Read More]
This year EGU published more than 3,375 peer-reviewed articles in our 19 Open Access journals. Upon learning about this impressive number of articles, we wondered: which of these were the most popular? You can find out in the following list of the most-read article for each EGU journal. From rainfall-runoff prediction, tipping points and open source hazard mapping, to the use of language around fr ...[Read More]
It’s been well established that tsunamis generate magnetic fields as they move seawater (which is conductive unlike freshwater) through the Earth’s magnetic field. Although researchers previously predicted that the tsunami’s magnetic field would arrive before a change in sea level, they lacked the means to simultaneously measure magnetics and sea level to confirm this phenomenon. Now, a new study ...[Read More]
Hello Meriel, thank you for speaking with us today! Could you introduce yourself? My name is Meriel Bittner and I am the Early Career Scientist Representative for the Ocean Sciences (OS) Division of EGU. Currently, I am a PhD fellow at the University of Copenhagen. Originally from Germany, I did my Bachelor and Master at the University of Vienna in Austria, hence I have attended multiple general a ...[Read More]
This year EGU published more than 3,300 peer-reviewed articles in our 19 Open Access journals. Upon learning about this impressive number of articles, which equates to just over 61,000 journal pages, we wondered: which of these were the most popular? You can find out in the following list of the most-read article for each EGU journal. From the substructure of extremely hot summers and the potentia ...[Read More]
Earlier this summer, as a global society we were reminded; our societies are riddled with inequalities. The deaths of Ahmaud Arbery, George Floyd, Breonna Taylor and other Black people over minor infringements of the law if any, flooded our news feeds; Black people like myself were reminded of just how dangerous our world is. The remnants of slavery and Jim-Crow era segregation are still felt in t ...[Read More]
