Secchi Dip-in encourages citizen monitoring this summer

A monitoring initiative named for Secchi disks encourages people across the world to test the water nearby from the end of June through mid-July. It’s called the Secchi Dip-in and its organizers want anyone with the means to test their local water to do so and report back.  The database is open to contributions from June 29 through July 21. Volunteers, monitoring groups and professionals alike can contribute data to the Secchi Dip-in database.  Turbidity data is the main information Secchi Dip-in organizers want to see, but they won’t turn down any kind of water quality data people contribute. They encourage interested environmentalists to go out with someone who is experienced in testing for water quality to ensure data is accurate.

Extreme Wave Heights, Ocean Winds Increasing Globally

Around the world, extreme wave heights and ocean winds are increasing. The greatest increase is happening in the Southern Ocean, according to recent research from the University of Melbourne , and Dr. Ian Young corresponded with EM about what inspired the work. “Our main interest is ocean waves, and we are interested in wind because it generates waves,” explains Dr. Young. “Ocean waves are important for the design of coastal and offshore structures, the erosion of beaches and coastal flooding, and the safety of shipping.” Waves also have a role in determining how much heat, energy and gas can be trapped in the ocean. “The major reason why changes in wave height may be important is because of sea level rise,” details Dr. Young.
