Scientists Believe Ocean Floor Is Sinking : A Well Thought Out Scream by James Riordan

Now here’s something I bet you haven’t thought about. Many scientists now believe that the ocean floor is sinking and that’s very bad – as if you didn’t have enough to worry about.  Another side effect of global warming is that melting glaciers are adding so much extra water into the world’s oceans that the ocean floor is sinking underneath its increasing weight.  Bet you didn’t see that one coming.  This deformation of the ocean floor also means that we have miscalculated just how much ocean levels and the coming deformation of the ocean floor are rising and the problem could be far worse than previously believed.

OceanSink3Decades of measurements and predictions of sea level rise could have underestimated the scale of the problem, experts warn, due to scientists not accounting for the weighty, warping effects of our ever burgeoning oceans. Existing assessments of sea level rise haven’t factored in that as the total ocean mass increases due to melting glaciers and ice sheets, the weight of all that extra water pushes down on the sinking ocean floor, deforming the seabed – and disguising just how much the oceans are truly swelling.  Over the past 20 years, ocean basins have sunk an average of 0.004 inches per year. This means that the ocean is 0.08 inches deeper than it was two decades ago. While this small fragment of an inch may not seem much, oceans cover 70 percent of our planet, making the problem bigger than it seems at an initial glance.

In a study published online in Geophysical Research Levels researchers explain how they used a mathematical equation known as the elastic sea level equation to more accurately measure the ocean floor. This allowed them to see how much the bottom of the ocean floor has changed from 1993 to 2014. While they are not the first scientists to look at the ocean floor, this is the first time that researchers have taken into account how additional water from melted ice may have further stretched the ocean floor.  The results show that the ocean is changing in ways that we previously did not realize and is sinking further into the earth’s crust. As a result, scientists have underestimated how much sea levels are rising by as much as 8 percent. The study concludes by emphasizing that future sea level measurement should take ocean floor deformation into account in order to more accurately understand how our oceans are changing.

OceanSink5“The Earth itself is not a rigid sphere, it’s a deforming ball,” geoscientist Thomas Frederikse from the Delft University of Technology in the Netherlands said. “With climate change, we do not only change temperature.”

The implications, according to Frederikse and his team, is that as the ocean bottom subsides elastically, the actual increasing volume of the ocean – called barystatic sea level rise – is masked from measurements based on satellite observations.

That’s because satellite readings only tell us one side of the story: geocentric sea level rise, as seen from the surface side. “Because satellite altimetry observes sea level in a geocentric reference frame, global mean sea-level estimates derived from altimetry will not observe the increase in ocean volume due to ocean-bottom subsidence, and hence, they may underestimate [global mean sea-level] rise,” the researchers explain in a new paper.

All the water on the planet today is all the water that has ever existed on the planet, but not all water is in its liquid form. Recently, rising temperatures have caused much of the frozen water on the planet’s glaciers to melt and join the ocean as liquid. This mass melting ice rising sea levels, a problem whose consequences we’re already starting to see. The first to notice the repercussions of rising sea levels are those who live in coastal areas. Rising waters mean less land to live on. In addition, more water in the ocean means that ocean storms, such as hurricanes, have the potential to be stronger and more devastating.  Small coastal areas won’t be the only ones to disappear due to rising waters and if current estimates are correct, by 2100 the ocean will rise between 11 and 38 inches, a number that could mean that much of the U.S. east coast will be covered in water.

Undersea Vocanoes

 

To quantify how much the bottom of the ocean is deforming under the extra load of meltwater, the researchers used various estimates of mass loss from glaciers, the Greenland and Antarctic ice sheets, and land water storage, including groundwater depletion and dam retention.

For roughly the last two decades (the period 1993–2014), the team calculates the increase of the total ocean load has pushed the seabed down by about 0.13 mm (0.005 inches) per year, or around 2.5 mm (almost 1 inch) in total for the period.

 

At the mid-ocean ridge, molten material rises from the mantle and erupts. The molten material spreads out, pushing older rock to both sides of the ridge. This process that continually adds to the ocean floor is sea floor spreading.

That might not sound like much, but in some regions the deformation is significantly greater – up to 1 mm (0.04 inches) per year over the Arctic Ocean, and 0.4 mm (0.016 inches) per year in the South Pacific.

Overall, the researchers say purely satellite-derived assessments of sea level rise for the period could have underestimated barystatic sea level rise by as much as 8 percent – which is definitely something we need to think about in the future, especially this hidden variable will only become more significant as the world gets hotter and sea level rise accelerates. “In a future warming climate, the sea-level rise induced by ice sheets will increase, and therefore, the magnitude of the bias due to elastic ocean-bottom deformation will grow,” the team writes. “To increase the accuracy of sea-level estimates, the effect of ocean-bottom deformation should be taken into account, either based on modeled estimates of ocean mass change, as was done in this study, or using more direct observations.”

James Riordan

Rare is it that any author will have one of his books described as the definitive work on a particular subject, but such a distinction has been bestowed by critics on no less than four books written by James Riordan. The New York Times Bestseller Break on Through, Riordan’s biography of Doors lead singer Jim Morrison, has not only been called “the most objective, thorough and professional Morrison biography” by the Times Book Review but also named as one of the Ten All Time Best Rock Biographies by Amazon.com. Riordan’s The Platinum Rainbow (written with Bob Monaco) was called “One of the best how-to books ever written” by the Los Angeles Daily News and “The ultimate career book on the music industry” by Recording, Engineer & Producer. Critics described Riordan’s The Bishop of Rwanda as “one of the most important books you’ll ever read.” and The Coming of the Walrus, Riordan’s novel about the 60s as “the definitive book on the era” and “a hilarious tale of a harrowing search for the greatest truth of all”. With the release of A Well Thought Out Scream and Madman in the Gate, Riordan pushed the boundaries again with poetry/song lyric books that contain hundreds of stunning, beautiful and poignant images from artists and photographers from all over the world. In the summer of 2013 a new edition of The Coming of the Walrus was released to rave reviews followed by The Kill Switch. The author of thirty-three books, James Riordan’s career began in the music industry where as a songwriter, manager, producer and concert promoter he worked with several well known artists. In 1976 he began writing a newspaper column, Rock-Pop, which he later syndicated. Riordan soon became one of America’s premier rock journalists with articles reaching millions of readers including those of Rolling Stone, Crawdaddy, Circus, Musician, and newspapers like The Chicago Daily News and The Kansas City Star. His reputation for relating on a one-to-one level soon led to interviews with George Harri-son, Bob Dylan, Fleetwood Mac, Frank Zappa, The Doobie Brothers, Kenny Rogers, Barbra Mandrell, Crosby, Stills & Nash and countless others. His first book, The Platinum Rainbow (written with Bob Monaco in 1980) became the largest selling book ever written about the music business. The guide to “succeeding in the music business without selling your soul” was praised by Variety ,The Chicago Tribune, The Los Angeles Times, The Las Vegas Sun, The Minneapolis Tribune, Billboard, Record World and many more. The Platinum Rainbow became an industry-wide phenomenon and interviews with James Riordan were aired on over 1200 radio stations and numerous television talk shows. Next Riordan collaborated with Pulitzer Prize winner Jason Miller on a mini-series for network television (The Irish) and a movie of the week for CBS (Bless Me Father). In June 1991, William Morrow & Co. published Break On Through to outstanding sales and reviews. Riordan worked as a consultant on Oliver Stone’s film of Morrison’s life, The Doors, which led to his writing Stone’s biography. Published by Hyperion /Disney in December 1995, Entertainment Weekly called STONE “an unflinching biography... enough spectacle to fill a month of daytime-TV talk shows.” The New York Post said reading the book was like “the sensory overload of watching all of Oliver Stone’s movies back to back.” Riordan was interviewed by Inside Edition, People Magazine, The Tom Snyder Show, and many others. From 1997-2000, Riordan created and co-starred in a local television program, Kankakee Valley Prime Time, which won six Crystal Communicators, three Tellys, and earned Riordan a Chicago/ Midwest Emmy Nomination for Writing the program. In the summer of 1999, James Riordan wrote, directed and starred in Maddance, an hour long dramatic project which won Crystal Communicators for Drama, Writing, Acting and Directing. On April 9, 2000, James’ 16 year old son, Jeremiah, was killed as a passenger in an accident that involved three drunk drivers. Shortly after this, James founded Make it Stick which works to warn teens of the dangers of substance abuse and publishes a magazine distributed to high school students. In 2001, he founded Jeremiah’s – A Place to be Yourself to give teens a place to hang out away from the dangers of drugs and alcohol. Force to close by its incredible growth rate, Jeremiah’s was recognized as one of the fastest growing and most successful teen centers in the United States. In 2004, Toastmasters International named Riordan Communicator of the Year for Central Illinois, the YMCA gave him their Service to Youth Award and the United Way named him the Outstanding Volunteer of Kankakee County. Returning to writing, Riordan went to Africa to write The Bishop of Rwanda, (with an intro by Purpose Driven Life author Rick Warren). In November of 2006, Harper Collins released a new edition of Break On Through followed by The Coming of the Walrus (Image Workshop) in December and The Bishop of Rwanda (Thomas Nelson, Inc.) to rave reviews (“Powerful …plumbs the depths of God’s forgiveness and finds no bottom – Publisher’s Weekly). In 2011, he won the Pledge For Life Harold Award for his work with area youth. In the summer of 2012, Lee and Shane Stanley (Gridiron Gang) optioned Maddance as a feature film followed by Apothecary Films optioning The Kill Switch in 2013 and Omni Films optioning Final Service to film in May. Riordan joined the staff of the Mancow Syndicated Television and Radio show in January of 2014 and is now seen and heard across America on a weekly basis. His biography is included in Who’s Who in Entertainment , Who’s Who in Poetry and Contemporary Authors of America.
