How do you get heavy machinery, such as a drill spool onto an ice sheet? This week’s imaggeo on Mondays’ photography captures the freighting of components of a hot water drill to directly access and observe the physical and geothermal properties at the ice-bed interface. In the image, SAFIRE principal investigator Bryn Hubbard and post-doc Sam Doyle help fly in the drill spool at the start of the Summer 2014 field campaign on Store Glacier, Western Greenland. Freighting several [...]
I spent the weekend reading the new paper in Nature last week that made a lot of news. (Justin Gillis at The NY Times has an excellent summary of the paper here). If you missed it, the short version is that for the first time, researchers used a series of coupled models to produce a more realistic look at what will happen to Antarctica in the coming decades and centuries. There

This month’s GeoEd post is brought to you by Dr. Mirjam S. Glessmer. Mirjam is a physical oceanographer turned instructional designer. She blogs about her “Adventures in Teaching and Oceanography” and tweets as @meermini. Get in touch if you are interested in talking about teaching and learning in the geosciences! Sometimes we look for new ways to engage our students or the general public in discussions about our science. Today I would like to suggest we use art! Someone recently told me [...]

This month’s GeoEd post is brought to you by Dr. Mirjam S. Glessmer. Mirjam, is a physical oceanographer and now works as Coordinator of Teaching Innovation at Hamburg University of Technology. Mirjam blogs about her “Adventures in Teaching and Oceanography” and tweets as @meermini. Get in touch if you are interested in talking about teaching and learning in the geosciences! “For the best hands-on outreach experiences, just provide opportunities for playing!” I claim. Seriously?

Nestled in the Arctic is a glacier like no other. This glacier quakes once a minute creating seismic events that rattle the earth—more frequently than scientists have ever seen. Understanding why these icequakes are so common may help researchers predict future ice flow, a process that propels climate-driven sea level
With the new science-based interactive app, users can explore ocean depths, ice sheet thicknesses, even the economic risks posed by flooding and sea level rise around the
By studying modeled climate evidence from the last interglacial period, the team concluded that the warming going on today risks setting off “feedbacks” in the climate
Will coral reefs and atolls (coral islands) be able to keep pace with the current and projected sea level rise and remain geologically stable in the coming decades and centuries? Will atolls in the Pacific and Indian Oceans remain habitable?
Regarding the first question, I came across a couple of recent studies that suggest that reef growth in the Pacific, Indian and Caribbean seas

Sea level rise from melting ice sheets in Antarctica and Greenland threaten catastrophe for coastal cities within decades unless strong measures are taken to reduce CO2 emissions from the use of fossil fuels, argues climate scientist James Hansen. Hansen’s warnings about the dangers of climate change are not new, but a new paper written by... read
While the ice sheets on West Antarctica and the Antarctic Peninsula are usually the ones to make the news in relation to climate change, recent studies have documented transformations that are taking place on the East Antarctic Ice Sheet as well. On the continent as a whole, large areas of ice have already melted and this trend shows no sign of slowing, meaning the implications for global sea level rise in this century could be more dramatic than earlier projections
Trying to define pornography, a frustrated U.S. Supreme Court Justice Potter Stewart once famously declared “I know it when I see it”, and perhaps you can say the same thing about critical thinking. Greg Laden (at Science Blogs) wrote a great post today about Bjorn Lomborg, a “famous” climate denier, and a statement he made about sea level rise. Laden then goes on to show just how ridiculous the argument

Guest post by Sarah G. Purkey and Gregory C. Johnson University of Washington / NOAA I solicited this post from colleagues at the University of Washington. I found their paper particularly interesting because it gets at the question of sea level rise from a combination of ocean altimetry and density (temperature + salinity) data. This
Glaciers in one part of West Antarctica are melting at triple the rate of a decade ago and have become the most significant contributor to sea level rise in that region, a new study says. The study found that the glaciers in the Amundsen Sea Embayment of West Antarctica have shrunk by an average of 83 gigatons a year for two decades—the equivalent of the weight of Mount Everest every two
The Earth’s surface temperatures can have a profound effect on the Earth’s ice sheets, the huge layers of ice thousands of metres thick that cover Greenland and Antarctica. Over the past few decades, satellites have monitored the changes of these icy landscapes, revealing that parts of Greenland and West Antarctica are melting. This is important as it contributes to sea level rise, which can have significant impacts on vulnerable coastal lands. So far, however, East Antarctica’s ice [...]
Up to $106 billion worth of coastal homes and businesses in the U.S. are likely to be underwater by the year 2050 due to rising sea levels, and up to $507 billion in coastal property will likely be below sea level by 2100, according to a new report released today. The report is based in part on a new study on sea level rise in Earth’s Future, a journal of the American Geophysical
U.S. News & World Report has a speculative article about using geoengineering to curb Antarctic ice loss and sea level
“A new study has found that the Antarctic Ice Sheet began melting about 5,000 years earlier than previously thought coming out of the last ice age – and that shrinkage of the vast ice sheet accelerated during eight distinct episodes, causing rapid sea level rise.” Quoted from the Oregon State University press
