The Growth Of Theoretical Paleontology

In 2012, David Sepkoski published a book entitled “Rereading the Fossil Record”. One of the chapters, entitled “The Growth of Theoretical Paleontology”, goes in depth about how theoretical paleontology has evolved over the years. Scientists are viewing dinosaurs in many ways that we’ve never viewed them before. Several theories about dinosaurs, such as those pertaining

Saharan dust feeds Amazon rainforest just enough to replace lost nutrient 

AGU Meetings [2015-02-24 16:02:51]  recommend  recommend this post  (27 visits) info
The Sahara Desert is a near-uninterrupted brown band of sand and scrub across the northern third of Africa. The Amazon rainforest is a dense green mass of humid jungle that covers northeast South America. But after strong winds sweep across the Sahara, a tan cloud rises in the air, stretches between the continents, and ties together the desert and the jungle. It’s dust. And lots of it. Scientists have not only used a satellite to measure the volume of dust that makes this trans-Atlantic [...]

Life After the First Core Came Up

Yes! Life suddenly became different. Many of us, mostly the scientists, who were sailing on-board the JOIDES Resolution as well as on an International Ocean Discovery Program expedition for the first time, had been occupied for the first few days to adopt the new life on-board, and to learn techniques that would be used for the research during the cruise. read

Shifting to Shifts

As we approach our first drill site, the scientists and technicians onboard the JOIDES Resolution have started moving to their assigned shifts.  As so much effort has been invested in these expeditions, and as we have a limited amount of time at sea, the ship operates around the clock and everyone works 12 hours a day, 7 days a week.  read

Study Finds Genetic Clues to How Plants Adapt to Climate

Using supercomputers to analyze hundreds of thousands of genetic markers in a thousand plant samples, scientists say they have found how a common weed uses its genetic code to adapt to changes in its environment such as freezing temperatures and drought. The findings add to our knowledge of how plant life evolves, and could be used to help breed crops that are more adaptable to climate change, the researchers

The EGU General Assembly brings together geoscientists from all over the world to one meeting that covers all disciplines of the Earth, planetary and space sciences. Following from last year’s success, the EGU General Assembly will have a theme: A Voyage Through Scales. The theme is an invitation to contemplate Earth’s extraordinary variability extending from milliseconds to its age and from microns to the size of the planet. The theme does not constrain the topics to be presented at the [...]

Measuring the temperature of solar winds 

AGU Meetings [2015-01-05 16:16:13]  recommend  recommend this post  (30 visits) info

 US
The sun spews forth super-heated, charged particles, collectively called plasma, that fly out into the vacuum of space at speeds of 200 to 400 miles per second (300 to 700 kilometers per second). These waves of plasma make up the solar winds that spread across our solar system. Traveling across freezing space should suck all the heat from the plasma by the time it nears Earth, but the solar waves detected near our planet are still hot. Scientists think something is happening within the [...]

The Larsen Ice Shelf is a huge piece of ice that sits on the other side of the Antarctic Peninsula from Rothera Station. It is divided into sections, which are named, from north to south (left to right, in the map), the Larsen A, B, and C. Back in 2002, a large piece of the Larsen B broke off into the ocean. The piece that broke off was 1,250 square miles, about the size of Rhode Island! It broke apart and fell into the ocean over a course of about a month. (You can see the satellite images of [...]

There are a lot of neat creatures living in the ocean around Antarctica: not just whales, seals, and penguins! There’s quite a diversity of invertebrates (animals without backbones) living on the ocean floor. We call these benthic invertebrates. (“Benthic” means they live on the bottom.)There are several scientists at Rothera who study these benthic invertebrates, and they shared some of their animals with me. There are some animals you are probably familiar with: sea stars (or starfish), [...]

Veteran geophysical tool preps for new horizons at Europa

Jupiter’s moon Europa has tantalized scientists with its potential for harboring life ever since Galileo first spotted the icy satellite in 1610. If living matter is bubbling anywhere in our solar system, they suspect, it would be below the moon’s icy shell, where a presumed ocean of salty water meets a mineral-rich interior. But because scientists can’t peer beneath the ice, they must rely on data beamed back by passing spacecraft. A proposed NASA mission called Europa Clipper could be [...]

All warmed up and nowhere to go: The missing El Niño of 2014

 US,PE,
In 1997, a record-breaking El Niño event in the Pacific Ocean brought rain to California, flooding to Peru, and drought to Africa. Earlier this year scientists said that warm currents in the Pacific Ocean presaged the biggest El Niño event since the record-breaking 1997-1998 season. The National Oceanic and Atmospheric Administration put the likelihood of a major Northern Hemisphere El Niño at 80 percent. But despite high expectations, the predicted El Niño of 2014 has ultimately fizzled. [...]
