The EIDO is a low cost, real-time sensing platform, specifically designed for the measurement of organic water quality parameters. Following the success of the award-winning Proteus, the EIDO has been specifically designed as a low-cost option for the measurement of organic parameters. The EIDO has been designed for its ease of use, reliable data and economical operation even in the toughest applications. Available in two sizes, the EIDO 30 provides turbidity, TSS, temperature and two fluorometers; while the EIDO 35 provides turbidity, TSS, temperature and up to four fluorometers.

Have You Heard? AI Buoys Revolutionizing Marine Mammal Monitoring in Whangārei Harbor, New Zealand

In one history, Whangārei Harbor, nestled in the lush hills of New Zealand’s North Island, gets its name from the Māori, “waiting for the breastbone of the whale.” It seems fitting, then, that it’s now home to state-of-the-art acoustic monitoring buoys listening for marine mammals around the clock. In September 2024, a team from Auckland-based underwater acoustics firm Cetaware Ltd installed NexSens buoys in Northport, a major commercial port at the entrance to the Whangārei Harbor. The first buoys to be installed by Cetaware in a permanent setting running 24/7, they use real-time artificial intelligence (AI) models to passively sense Delphinidae–from common dolphins to orcas.

Wildfires and Wildlife: Relocating Coastal Rainbow Trout to the Arroyo Seco Stream

Human interaction has negatively impacted the hundreds of streams that run through Southern California. Man-made river and stream diversions, channeling, and damming have changed the physical and chemical characteristics of these waterways. In addition to physical impairments, climate change is increasingly impacting the ecosystems of streams. To evaluate and mitigate these negative impacts, local groups are monitoring the riparian habitats of these streams and are conducting water surveys that document rainbow trout populations and evaluate water quality .

Bringing Fish Back: Reviving Britain’s Freshwater Habitats with the Wild Trout Trust

Freshwater covers less than 1% of the Earth’s surface but has an outsized impact on global ecosystems, supporting more than 10% of all known species, reports the World Wildlife Fund . Freshwater environments such as rivers and wetlands provide significant scientific, economic, and cultural value. But pressure from climate change, biodiversity loss, and a lack of prioritization in environmental policies mean freshwater habitats are recognized as one of the most threatened in the world–something scientists have dubbed an “invisible tragedy. ” [caption id="attachment_39210" align="alignnone" width="940"] Remedial works underway to shore up the banks of the River Ecclesbourne.
