Sewage an Unseen and Ignored Threat to Coral Reefs and Human Health
It’s an open, dirty secret that the ocean is used as the ultimate sewage solution. Each year trillions of gallons of untreated waste are sent to the ocean due to a widespread lack of sanitation technology or infrastructure that needs updating as cities and populations grow. As the impact of untreated sewage on the ocean becomes clearer, attention to the problem and strategies for dealing with it have not kept up. “This is a massive problem and it’s been largely ignored,” said Stephanie Wear, senior scientist and strategy advisor for The Nature Conservancy. Wear has turned her attention to raising the alarm about the effects of sewage on coral reefs, which often loses airtime to other pressing issues like climate change and overfishing.

Monitoring OAE Efforts in Halifax: Fighting Climate Change with Emerging mCDR Strategies
Marine carbon dioxide (CO 2 ) removal (mCDR) is an emerging strategy that aims to fight climate change by taking advantage of the carbon capture potential of our oceans. There are multiple types of mCDR approaches being evaluated globally, one of which is ocean alkalinity enhancement (OAE). According to NOAA , OAE aims to increase the pH of water by either adding alkaline material to ocean surface waters or by removing acid from seawater. Due to the change in acidity, the chemistry of seawater changes, making it capable of absorbing greater volumes of CO 2 .

Lake Erie Volunteer Science Network: Building Trust in Citizen Science Programs
Citizen science programs have popped up across the United States, focusing on connecting local communities with nearby water resources and building a trustworthy data pool over the sampling period. While commonly utilized as a means of ensuring that large watersheds or lake regions are adequately sampled, the credibility and success of such programs have been called into question. [caption id="attachment_38996" align="alignnone" width="940"] HRWC volunteers measure stream velocity across a subsection of Woods Creek, a tributary of the Huron River near Belleville, Michigan. Stream velocity measurements can be combined with water level measurements to calculate stream flow and chemical parameter loads.
