The MX20L Water Level Logger brings all the same great features as the U20L and more! Integrating Bluetooth for fast and reliable data download, the MX20L logger eliminates the need to plug your logger into a base station or shuttle to offload data in the field, ensuring continuous water level and temperature monitoring. With options to measure at depth ranges of 13, 30, or 100 feet in a wide range of underwater environments, this rugged logger features 0.1% measurement accuracy, a durable polypropylene housing for use in both freshwater and saltwater, and a non-vented design for convenient and reliable deployment.

The MX20L comes with a magnetic activation fob that can "wake up" the logger to activate its Bluetooth communication for configuration and data download. The included fob comes with a lanyard to prevent losing or dropping the fob in the field.

This logger records absolute pressure, which is later converted to water level readings by HOBOconnect software. To compensate for barometric pressure changes, another HOBO MX20L Water Level logger can be used as a barometric reference.

  • Self-contained, non-vented design enables easy deployment
  • Ideal for use in both freshwater and saltwater environments, including wells, streams, lakes, wetlands, and tidal areas
  • Depth measurement options of up to 13, 30, or 100 feet depending on model
  • Durable ceramic pressure sensor withstands freezing
  • Streamlined data offload via Bluetooth to the free HOBOconnect app
  • HOBOconnect app provides easy extraction and visulization of water level data
  • Extended battery life up to 10 years (power-saving mode requires magnetic fob to activate Bluetooth for data download)
  • (1) HOBO MX20L water level & temperature logger
  • (1) HOBO magnetic activation fob

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.
