June GeoRoundUp: the best of the Earth sciences from around the web

June GeoRoundUp: the best of the Earth sciences from around the web

Drawing inspiration from popular stories on our social media channels, as well as unique and quirky research news, this monthly column aims to bring you the best of the Earth and planetary sciences from around the web.

Major Story

With June being the month when the world’s oceans are celebrated with World Ocean Day (8th June) and the month when the UN’s Ocean Conference took place, it seemed apt to dedicate our major story to this precious, diverse and remote landscape.

In fact, so remote and inaccessible are vast swathes of our oceans, that 95% of them are unseen (or unvisited) by human eyes. Despite their inaccessibility, humans are hugely reliant on the oceans.  According to The World Bank, the livelihoods of approximately 10 to 12% of the global population depends on healthy oceans and more than 90%of those employed by capture fisheries are working in small-scale operations in developing countries. Not only that, but the oceans trap vast amounts of heat from the atmosphere, limiting global temperature rise.

Yet we take this valuable and beautiful resource for granted.

As greenhouse gas emissions rise, the oceans must absorb more and more heat. The ocean is warmer today than it has been since recordkeeping began in 1880. Over the past two decades this has resulted in a significant change in the composition of the upper layer of water in our oceans. Research published this month confirms that ocean temperatures are rising at an alarming rate, with dire consequences.

Corals are highly sensitive to changes in ocean temperatures. The 2015 to 2016 El Niño was particularly powerful. As its effects faded, ocean temperatures in the Pacific, Atlantic and Indian oceans remained high, meaning 70 percent of corals were exposed to conditions that can cause bleaching. Almost all of the 29 coral reefs on the U.N. World Heritage list have now been damaged by bleaching.

This month, the National Oceanic and Atmospheric Administration (NOAA) declared that bleaching was subsiding for the first time in three years. Some of the affected corals are expected to take 10 to 15 years to recover, in stress-free conditions. But as global and ocean temperatures continue to rise, corals are being pushed closer to their limits.

Warmer ocean temperatures are also causing fish to travel to cooler waters, affecting the livelihoods of fishermen who depend on their daily catch to keep families afloat and changing marine ecosystems forever. And early this month, millions of sea-pickles – a mysterious warm water loving sea creature- washed up along the western coast of the U.S, from Oregon to Alaska. Though scientists aren’t quite sure what caused the bloom, speculation is focused on warming water temperatures.

It is not only warming waters which are threatening the world’s oceans. Our thirst for convenience means a million plastic bottles are bought around the world every minute. Campaigners believe that the environmental crisis brought about by the demand for disposable plastic products will soon rival climate change.

In 2015 researchers estimated that 5-13 million tonnes of plastics flow into the world’s oceans annually, much coming from developing Asian nations where waste management practices are poor and the culture for recycling is limited. To tackle the problem, China, Thailand, Indonesia and the Philippines vouched to try and keep more plastics out of ocean waters. And, with a plastic bottle taking up to 450 years to break down completely, what happens to it if you drop it in the ocean? Some of it, will likely find it’s way to the Arctic. Indeed, recent research suggests that there are roughly 300 billion pieces of floating plastic in the polar ocean alone.

And it’s not only the ocean waters that are feeling the heat. As the demand for resources increases, the need to find them does too. The sea floor is a treasure trove of mineral and geological resources, but deep-sea mining is not without environmental concerns. Despite the ethical unease, nations are rushing to buy up swathes of the ocean floor to ensure their right to mine them in the future. But to realise these deep-water mining dreams, advanced technological solutions are needed, such as the remote-controlled robots Nautilus Minerals will use to exploit the Bismarck Sea, off the coast of Papua New Guinea.

Lightning reportedly ignited a deadly wildfire in Portugal, seen here by ESA’s Proba-V satellite on 18 June.

“On June 17, 2017, lightning reportedly ignited a deadly wildfire that spread across the mountainous areas of Pedrógão Grande—a municipality in central Portugal located about 160 kilometers (100 miles) northeast of Lisbon”, reported NASA – National Aeronautics and Space Administration. The death toll stands at 62 people (as reported by BBC News). The fires were seen from space by satellites of both NASA and ESA – European Space Agency satellites.

Large wildfires are also becoming increasing common and severe in boreal forests around the world. Natural-color images captured by NASA satellites on June 23rd, shows wildfires raging near Lake Baikal and the Angara River in Siberia. At the same time, a new study has found a link between lightning storms and boreal wildfires, with lightning strikes thought to be behind massive fire years in Alaska and northern Canada. This infographic further explores the link between wildfires triggered both by lightning and human activities.

Meanwhile, in the world’s southernmost continent the crack on the Larsen C ice-shelf continues its inexorable journey across the ice. The rift is set to create on of the largest iceberg ever recorded. Now plunged in the darkness of the Antarctic winter, obtaining images of the crack’s progress is becoming a little tricker. NASA used the Thermal Infrared Sensor (TIRS) on Landsat 8 to capture a false-color image of the crack. The new data, which shows an acceleration of the speed at which the crack is advancing, has lead scientists to believe that calving of the iceberg to the Weddell Sea is imminent.

The EGU story

This month saw the launch of two new division blogs over on the EGU Blogs: The Solar-Terrestrial Sciences and the Geodynamics Division Blogs. The EGU scientific divisions blogs share division-specific news, events, and activities, as well as updates on the latest research in their field.

And don’t forget! To stay abreast of all the EGU’s events and activities, from highlighting papers published in our open access journals to providing news relating to EGU’s scientific divisions and meetings, including the General Assembly, subscribe to receive our monthly newsletter.

Announcing the winner of the EGU Best Blog Post of 2016 Competition

Announcing the winner of the EGU Best Blog Post of 2016 Competition

There is no doubt that 2016 was packed full of exciting, insightful and informative blog posts. An impressive 360 posts were published across the EGU’s official blog, GeoLog, as well as the network and division blogs!

In December, to celebrate the excellent display of science writing across the network and division blogs, we launched the EGU Blogs competition. From a list of posts selected by our blog editors, we invited you, the EGU Blogs readers, to vote for your favourite post of 2016. After a little over three weeks of voting, the winners are finally in!

Without further ado, we’d like to extend a big congratulations to the Cryosphere Blog, who take this year’s crown, with a 58% share of the votes, for their post following the journey of a snowflake! From the water vapour in a cloud to the snowman in your garden, find out what leads to the complex structure you can see on in the image below!

All the posts entered into the competition are worthy of a read too, so head over to the poll and click on the post titles to learn about a variety of topics: from the fate of Fukushima Iodine-129 in rain and groundwater, to exploring whether letters of recommendation are the key to the leaky pipeline in academia and how common soft sediment structures like slumps and flames form.

If the start of a new year, with its inevitable resolutions, along with the range and breadth of posts across the EGU Blogs have inspired you to try your hand at a little science writing then remember all the EGU Blogs welcome (and encourage!) guest posts.  Indeed, it is the variety of guest posts, in addition to regular features, which makes the blogs a great read! If you would like to contribute to any of the network, divison blogs or GeoLog, please send a short paragraph detailing your idea to the EGU Communications Officer, Laura Roberts at networking@egu.eu.

 

Revamping the EGU blog network: call for bloggers

Revamping the EGU blog network: call for bloggers

The EGU blog network is getting a make-over! Since 2013 the network blogs have enjoyed thought-provoking and engaging contributions by Simon Redfern, Dan Schillereff and Laura Roberts, Jon Tennant, as well as Will Morgan on a range of topics: from the workings of the inner Earth, through to geomorphology, palaeontology and air quality. However, the individual circumstances of the bloggers now mean that it is no longer viable for them to regularly update their blogs. As such, it is with sadness that we announce that we are saying goodbye to Atom’s Eye on the Planet, Geology Jenga, Green Tea and Velociraptors and Polluting the Internet. From the EGU, we thank Simon, Dan, Laura, Jon and Will for contributing excellent content to the blogs and wish them the very best of luck for the future.

To complete the make-over, we’d like to find new blogs to take the place of the departing network blogs. If you are an Earth, planetary or space researcher (a PhD student, an early career scientist, or a more established one) with a passion for communicating your work, we’d like to hear from you!

We currently feature blogs in international development (Geology for Global Development), geochemistry (GeoSphere), volcanology, (VolcanincDegassing) and geopolicy (Four Degrees). We’d love to receive blog proposals from fields within the Earth, planetary and space sciences we don’t yet feature. The network aims at fostering a diverse community of geoscience bloggers, sharing accurate information about geoscientific research in a language understandable not only to fellow scientists but also to the broader public. You, as an expert in your own research area, are in a better position than we are to share recent development in your area of research.

The benefits: apart from your site gaining exposure by having its posts listed on the front page of the EGU website, we will also share highlights of your work on our social media channels (Twitter, Facebook, LinkedIn, Google+, Instagram) and advertise the blog network at our General Assembly, which has over 12,000 attendees. And, of course, you’ll get to join a great community of bloggers!

With the exception of VolcanicDegassing, the network blogs are authored by early career researchers. In this call for bloggers we are particularly keen to add diversity to the network, and particularly welcome applications from more established scientists.

Having an existing blog is not a requirement for application. However, if you don’t have a blog already, we’d like you to have at least some experience of writing for a broader audience, be it as a guest blogger, or contributing to outlets such as The Conversation, for instance. In this case, let us know what you’d like your blog to be called, what topics you would cover, and link to articles you’ve published in the past.

If you’d like your blog (or blog idea) to be considered for our network, fill out this form by 8th August.

Please note that only blogs in English will be considered, as this is the EGU working language, and the language of the blog network. We particularly encourage applications from all European countries, not just English-speaking countries, but bloggers from outside Europe can also apply.

Feel free to contact the EGU Communications Officer Laura Roberts if you have any questions. In the meantime – happy blogging!

After announcing earlier this week that we are sadly saying goodbye to the EGU network blog Between a Rock and Hard Place, the time has come to find a new blog to take their place. If you are an Earth, planetary or space researcher (a PhD student, an early career scientist, or a more established one) with a passion for communicating your work, we’d like to hear from you!

We currently feature blogs in palaeontology (Green Tea and Velociraptors), international development (Geology for Global Development), geochemistry (GeoSphere), atmospheric sciences (Polluting the Internet), and more! Initially, we are looking to fill the gap left in the network by Between a Rock and Hard Place, which covered broad themes within volcanology and petrology. But, with so much great geoscience out there, we’d love to receive blog proposals from more fields within the Earth, planetary and space sciences we don’t yet feature on the network. This also means we may not limit the addition to the EGU network to one blog; if there is more than one strong candidate we’ll consider expanding the network further.

The network aims at fostering a diverse community of geoscience bloggers, sharing accurate information about geoscientific research in a language understandable not only to fellow scientists but also to the broader public. You, as an expert in your own research area, are in a better position than we are to share recent development in your area of research.

The benefits: apart from your site gaining exposure by having its posts listed on the front page of the EGU website, we will also share highlights of your work on our social media channels (Twitter, Facebook, LinkedIn, Google+) and advertise the blog network at our General Assembly, which has over 12,000 attendees. And, of course, you’ll get to join a great community of bloggers!

With the exception of An Atom’s-Eye View of the Planet, the network blogs are authored by early career researchers. In this call for bloggers we are particularly keen to add diversity to the network, and particularly welcome applications from more established scientists.

Having an existing blog is not a requirement for application. However, if you don’t have a blog already, we’d like you to have at least some experience of writing for a broader audience, be it as a guest blogger, or contributing to outlets such as The Conversation, for instance.
