Research suggests Saturn’s moon Dione may harbor a subsurface ocean

Research suggests Saturn’s moon Dione may harbor a subsurface ocean

A subsurface ocean could lie deep within Saturn’s moon Dione, according to a new study using publicly available data from the Cassini mission to Saturn. In 2013, images from NASA’s Cassini spacecraft hinted that Dione had a subsurface ocean when the moon formed, but the new study suggests the ocean could still exist today.

New research explores how wetlands and agriculture could be causing a global rise in methane

New research explores how wetlands and agriculture could be causing a global rise in methane

New research shows recent rises in methane levels in the atmosphere are most likely driven by biological sources, such as swamp gas, cow burps, or rice fields, rather than fossil fuel emissions.

Ms. Callaghan’s Classroom: The Underwater Flying Glider

Ms. Callaghan’s Classroom: The Underwater Flying Glider

What’s a glider? It is an underwater robot that “flies” around the sea going from the surface to the bottom of the seafloor collecting different types of science data.

Sikuliaq week 2 recap

Sikuliaq week 2 recap

We’ve done a lot of science this week! Since the last update, we’ve successfully towed the super sucker, started multi-coring, and upped our CTD tally to a whopping 87 casts, plus all the continuous surface underway data we’ve collected while steaming between sites. The scientists have some preliminary results and ideas about where they’d like to visit again (the beginning of the Wainwright line is of particular interest).

Human activities rattle natural rock of Utah’s Rainbow Bridge

Human activities rattle natural rock of Utah’s Rainbow Bridge

Utah’s iconic Rainbow Bridge hums with natural and man-made vibrations, according to a new study accepted for publication today in Geophysical Research Letters, a journal of the American Geophysical Union. The study found both natural waves in Lake Powell and induced earthquakes in Oklahoma cause the rock bridge to vibrate at different resonant frequencies.

Ms. Callaghan’s Classroom: Multi-coring

Ms. Callaghan's Classroom: Multi-coring

It was so cool to watch pieces of ice float by as we were working on deck! I’m standing next to the hose because we wash off the utensils (the metal sheet for cutting, the spatula used for scraping it into the bag, and the plastic ring) in between samples so that we don’t contaminate one layer with mud from another!

New study “reels in” data on Utah’s winter ozone problem

New study “reels in” data on Utah’s winter ozone problem

A deep sea fishing rod is probably not the first tool that comes to mind when thinking about how to study air pollution in a remote inland desert, but it’s the heart of a new system that has given scientists a minute-by-minute look at how quickly the sun can convert oil and gas emissions to harmful ground-level ozone.

Scientists investigate how atmospheric rivers may change as climate warms

Scientists investigate how atmospheric rivers may change as climate warms

A high-resolution climate model based at the National Center for Atmospheric Research (NCAR) is able to accurately capture the ribbons of moist air that sometimes escape the sodden tropics and flow toward the drier mid-latitudes, allowing scientists to investigate how “atmospheric rivers” may change as the climate warms.
