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.

Acidification May Ease Struggle to Survive for Herring Larvae

Survival in the ocean is no easy task, especially for ichthyoplankton, the eggs and larvae of fish. For most, including herring larvae, once they're released into the water, they're on their own, with survival as their sole goal. Climate change is making that goal more difficult to obtain for many species, but the changes to the marine atmosphere that come along with a warming climate are complex, and they affect various species in different ways. Scientists are still trying to research what some of those differences might look like. Struggle for survival Ichthyoplankton are vulnerable to predators, of course, but they are also highly sensitive to their environment. This means changes in dissolved oxygen levels, temperature, and pH can all be dangerous to fish eggs and larvae.

WHO also indicates that 2.1 billion people cannot access clean drinking water in their homes, while nearly 1 billion people lack access to clean drinking water at all—and of course those figures will grow more dire as climate change alters the environment and reduces. However, heavy metals find their way into water in multiple ways. Industrial concerns cause metals to leach into the water supply, either accidentally or by actively dumping waste .
