Within minutes of walking on a San Diego beach, marine ornithologist Tammy Russell found the feathered carcasses – one after another.
Some were mixed in with washed up kelp. Others were under rocks.
Each month, scientists and volunteers conduct surveys of dead seabirds and find what Russell describes as a grim assessment of the impact of a massive marine heat wave that has lingered for months off parts of the California coast.
The surveys that have been carried out by various organizations for decades help build a baseline of information on beached sea life to detect threats and their impact.
Many seabirds, including California brown pelicans, loons and grebes, starved to death in recent months as record-setting ocean temperatures decreased the band of cold, nutrient-rich surface water where krill, anchovies and sardines thrive near the shore, said Russell, a postdoctoral scholar at the University of California, San Diego’s Scripps Institution of Oceanography.
A well-worn expression among oceanographers and others who explore the watery depths of planet Earth is that we humans “know the surface of Mars better than our ocean floors.” Covering more than 70 percent of the world’s surface, oceans are notoriously difficult to study—not to mention pretty inhospitable to any creatures sans gills.
Sometime on Oct. 21 of last year, high above the Arctic Circle, a lone missile shot skyward from a Russian island.
‘This would have been a wild dream a year ago,” says Andrea Ceccolini, standing on Arctic sea ice just a 4-mile snowmobile ride from the Inuit town of Cambridge Bay, northern Canada. To his left are sky blue ponds of meltwater created in the last few days by a sun that no longer sets in the high north summer. To his right, the sea ice is still a brilliant white, the light dusting of snow on top continuing to sparkle.
Time to look up, stargazers – there’s going to be a planetary "kiss" on June 9.
Standing in his laboratory, Harvard professor Sean Eddy gazes at a row of vacant work stations. More than a year ago, this lab was filled with over a dozen researchers. On a given day they might be working independently on analyzing genomic sequencing or gathered around the group table, drinking coffee and helping each other troubleshoot questions about genomic data from different species.
Brilliant splashes of green, purple and pink will streak the night sky for many stargazers in North America on Saturday and Sunday night, as energized particles from space collide with the Earth's atmosphere to create the dazzling effect, known as the Northern Lights or aurora borealis.
