Exploring Earth’s final frontier

Covering more than 70 percent of Earth’s surface, the oceans act as our planet’s heartbeat, with differences in depths, currents, temperature and salinity marking changes in its pulse. While these measurements are fairly straightforward, the information they relay about Earth’s health is much more complex. As the planet warms, much of the heat is absorbed in the oceans, resulting in rising sea levels and changes to how water mixes and currents move.

Could brighter clouds offset warming caused by greenhouse gas emissions?

Brighter clouds can increase reflectivity

Atmospheric Sciences’ Tom Ackerman and Rob Wood recently contributed to a proposal that would test the effectiveness of spraying sea-salt particles into marine clouds in order to make them brighter. According to The Economist, cloud physicist John Latham hypothesized that brighter clouds could cool the Earth enough to compensate for increased warming caused by greenhouse gas emissions in 1990. Several decades later and with the help of the two UW scientists, field tests on the subject could come to fruition.

Join expedition online: UW students help install cabled deep-sea observatory

NSF/-OOI/UW/CSSF

Students at the College of the Environment got a taste of what doing oceanographic research is all about this summer, spending numerous days at sea aboard the UW’s giant research vessel, the Thomas G. Thompson. The project: installing an underwater, cabled ocean observatory that will give scientists a continuous presence in the Pacific waters off of Oregon and Washington.

Tethered robots tested for Internet-connected ocean observatory

The University of Washington this fall will complete installation of a massive digital ocean observatory. Dozens of instruments will connect to power and Internet cables on the seafloor, but the observatory also includes a new generation of ocean explorers: robots that will zoom up and down through almost two miles of ocean to monitor the water conditions and marine life above.

Embarking on geoengineering, then stopping, would speed up global warming

Earth

Spraying reflective particles into the atmosphere to reflect sunlight and then stopping it could exacerbate the problem of climate change, according to new research by atmospheric scientists at the University of Washington. Carrying out geoengineering for several decades and then stopping would cause warming at a rate that will greatly exceed that expected due to global warming, according to a study published February 18 in Environmental Research Letters.
