Like all good explorers who are preparing for the unknown, I went looking for information about what to expect in the place where we will spend the better part of two months. Thanks to Rob Larter who had tweeted information about the sea ice in December, I found Sentinel-1 SAR imagery imagery that shows the […]

THOR 2019 Cruise News- THOR team gets ready to set sail for Antarctica

In just a little less than one week, the THOR (Thwaites Glacier Offshore Research) science team members (including EEPS science writer Linda Welzenbach) will embark on a two month cruise to the Amundsen Sea, Antarctica. The mission: collect sediment cores from the seafloor beyond Thwaites Glacier that record its past behavior. They will also collect […]

Planetary collision that formed the moon made life possible on Earth

JADE BOYD – JANUARY 23, 2019 Study: Planetary delivery explains enigmatic features of Earth’s carbon and nitrogen Most of Earth’s essential elements for life — including most of the carbon and nitrogen in you — probably came from another planet. Earth most likely received the bulk of its carbon, nitrogen and other life-essential volatile elements from […]

Feds, states can help biochar live up to its soil-saving potential

MIKE WILLIAMS – JANUARY 11, 2019 Study shows how government promotes agricultural, environmental benefits – and could do more Even though every dollar spent on soil improvement can save much more in environmental costs down the road, startup costs can sometimes make it hard for farmers to implement best environmental practices. A team of researchers […]

‘True polar wander’ may have caused ice age

JADE BOYD – NOVEMBER 19, 2018 Rice U. scientists use Hawaiian hot spot to study movement of Earth’s poles Earth’s latest ice age may have been caused by changes deep inside the planet. Based on evidence from the Pacific Ocean, including the position of the Hawaiian Islands, Rice University geophysicists have determined Earth shifted relative […]

Ice-age climate clues unearthed

Rice scientist’s method helps interpret climate data from lake sediments MIKE WILLIAMS – OCTOBER 24, 2018 How cold did Earth get during the last ice age? The truth may lie deep beneath lakes and could help predict how the planet will warm again. Sediments in lake beds hold chemical records of ages past, among them the […]

Tiny northwest quakes tied to deep-crust structure

MIKE WILLIAMS – OCTOBER 25, 2018 Rice University scientists uncover relationship between tremors, water at the Cascadia margin HOUSTON – (Oct. 25, 2018) – The earthquakes are so small and deep that someone standing in Seattle would never feel them. In fact, until the early 2000s, nobody knew they happened at all. Now, scientists at Rice […]
