This Earth Day weekend, over 100 students from 20+ U.S. states, including Alaska and Hawaii, will chart their course to the University of Colorado Boulder, to match wits in the National Ocean Sciences Bowl. The student finalists will put their knowledge to the test—expertly answering Jeopardy-style trivia questions on topics including marine chemistry, policy, biology, and more. CIRES will host the competition here in Boulder—it’s the first time the nationals have been held in a fully landlocked state.
National Ocean-Science Competition Makes a Splash in Colorado
Arctic Sea Ice Maximum Second Lowest in Satellite Record
Sea ice over the Arctic Ocean likely reached its maximum extent for the year, at 14.48 million square kilometers (5.59 million square miles) March 17, the second lowest in the 39-year satellite record, falling just behind 2017. This year’s maximum extent is 1.16 million square kilometers (448,000 square miles) below the 1981 to 2010 average maximum of 15.64 million square kilometers (6.04 million square miles).
Detecting Methane from Miles Away
A new field instrument developed by a collaborative team of researchers can quantify methane leaks as tiny as 1/4 of a human exhalation from nearly a mile away. CIRES, NOAA, CU Boulder, and NIST scientists revamped and “ruggedized” Nobel Prize laser technology—turning a complex, room-sized collection of instruments into a sleek, 19-inch portable unit to tote into the field near oil and gas operations. The instrument collects precise, nonstop data, providing game-changing information critical for safe industry operations and controlling harmful greenhouse gas emissions.
