In a world-first, the extent of human development in oceans has been mapped. An area totalling approximately 30,000 square kilometres—the equivalent of 0.008 percent of the ocean—has been modified by human construction.

The extent of oceanmodified by human construction is, proportion-wise, comparable to the extent of urbanised land, and greater than the global area of some natural marine habitats, such as mangrove forests and seagrass beds.

Something as simple as black paint could be the key to reducing the number of birds that are killed each year by wind turbines. According to a study conducted at a wind farm on the Norwegian archipelago of Smøla, changing the color of a single blade on a turbine from white to black resulted in a 70-percent drop in the number of bird deaths.

..in 2013, each of the four turbines in the test group had a single blade painted black. In the three years that followed, only six birds were found dead due to striking their turbine blades. By comparison, 18 bird deaths were recorded by the four control wind turbines—a 71.9-percent reduction in the annual fatality rate.

The National Science Foundation is awarding Ohio Wesleyan University a one-year, $86,735 grant to oversee the creation of online teaching tools that advance field ecology and data science.

Laurel J. Anderson, Ph.D., OWU’s Morris Family Professor of Natural Sciences, is the principal investigator on the federal grant. She also is president of the Board of Directors for the Ecological Research as Education Network (EREN), a consortium of colleges and universities that will work together to create the new teaching tools. Dr. Anderson will partner with Dr. Tim McCay from Colgate University to administer the project.

“The pandemic has created an urgent need to reimagine our teaching of field ecology, which is usually done with in-person field trips,” said Dr. Anderson, who helped to found EREN in 2010.

“However, field ecologists also use computer technology extensively to explore natural patterns at large scales,” she continued. “These projects allow us to meet our need to socially distance and have students collecting data wherever they happen to be. Then, we use online tools and datasets to see how their data fits into large-scale patterns.”

In a world first, University of Hong Kong marine institute scientists lay clay tiles in marine park where coral was wiped out in twin ecological catastrophes

Seeded with living corals, the tiles quickly increased biodiversity. If found to work, they could transform reefs damaged by pollution, fishing and bleaching

There probably is more carbon dioxide in the air now than at anytime in 3 million years

The coronavirus pandemic’s economic downturn may have set off a sudden plunge in global greenhouse gas emissions, but another crucial metric for determining the severity of global warming — the amount of greenhouse gases actually in the air — just hit a record high.

According to readings from the Scripps Institution of Oceanography and the National Oceanic and Atmospheric Administration (NOAA), the amount of CO2 in the air in May 2020 hit an average of slightly greater than 417 parts per million (ppm). This is the highest monthly average value ever recorded, and is up from 414.7 ppm in May of last year.
