Through the Looking Glass: Peering Through the Bottom of the Ocean
Alice stepped through the mirror to see the world beyond, and we peer through the bottom of the ocean to see what is below. Short pulses of sound from the ship are focused on the seafloor, and we listen to the echo and reverberations that return.

Calmer Seas Ahead
After a short break due to weather and a bit of fun with Styrofoam cups, we are back in the lab sampling phytoplankton in the Bering Sea. We are using a specialized instrument to determine how well these small plant-like creatures are able to photosynthesize in the ocean, and we continue to learn fun facts…

Exploring the Bering Sea Ecosystem
Our stations have continued to be rich in phytoplankton, while our colleagues are excited by the larval fish they are finding in the southern Bering Sea. Wildlife sightings have included whales, dolphin, and the jawless lamprey fish, and we are settling in for potentially bumpy seas ahead.

Switchyard 2012: Climate Change in the Arctic
Arctic summer sea ice is declining rapidly: a trend with enormous implications for global weather and climate. Now in its eighth year, the multi-year Arctic Switchyard project is tracking the Arctic seascape to distinguish the effects of natural climate variability from human-induced climate change. The University of Washington is leading the project. A) The Canadian…

The Double-Edged Sword of Geoengineering
Shooting sulfur particles into the stratosphere to reflect the sun? Dumping iron into the ocean to boost the absorption of carbon dioxide? Could these far-fetched and dangerous-sounding schemes—geoengineering—help avert potentially catastrophic effects of climate change, or would they exacerbate conditions on our ever warming planet?

World Climate Policies: Substantial Progress But Enormous Challenges Remain
Recent analysis by Deutsche Bank Climate Change Advisory (DBCCA) in conjunction with the Columbia Climate Center, shows that the existing world climate policies have the potential to substantially reduce CO2 emissions, but are not aggressive enough to meet the suggested 450 ppm stabilization pathways.
