Overview
The Zebra-Tech LI-COR LI-192 Hydro-Wiper is a mechanical wiper system designed to fit easily to the LI-COR LI-192. Using a regular gentle brushing action, the Hydro-Wiper keeps the optical window of the LI-COR LI-192 clean from bio-fouling and other unwanted deposits such as mud. The Hydro-Wiper reduces the need for costly site visits to manually clean the instrument, maintaining data integrity throughout long deployments.
Self-Contained
The Zebra-Tech LI-COR LI-192 Hydro-Wiper consists of a wiper unit attached via a purpose-designed clamp. The wiper is connected to a rugged underwater housing, which contains the batteries, control electronics, diagnostic LED and wipe interval select switch.
Data Logger Controlled
The wiper is connected to the Hydro-Wiper control module by an electrical cable. To initiate a wipe, the data logger simply sends a trigger signal to the control module. Synchronizing the wipe with measurements ensures data quality is consistent throughout the deployment.

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.

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 .

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. ”
