Lake Superior has algae blooms, too | The Narwhal Long a threat to southern Ontario lakes, climate change is making even the coldest of the Great Lakes home for cyanobacteria — or blue-green algae

As Lake Superior warms, it's growing greenish clouds of blue-green algae, which is actually a bacteria. One researcher is tracking it himself, saying authorities aren't acting fast enough to educate the public about preventing blooms and avoiding their dangers. thenarwhal.ca/lake-superio...

The Great Lakes are powerful. Learning about ‘rip currents’ can help prevent drowning To ensure a safe trip to the beach, seek out information about rip currents and other surf hazards in the Great Lakes.

🌊 Heading to the beach this summer?


Water Institute researcher Dr. Chris Houser explains how learning to spot rip currents and surf hazards in the Great Lakes can help keep you—and others—safe.

🔎 In The Media: Water Institute researcher Dr. Luna Khirfan says expanding urban water bodies can help cool our cities during extreme heat.

But it takes more than one solution—cities need a coordinated, nature-based approach.

How salty is that urban creek? - Article - DataStreamHow salty is that urban creek? - Article - DataStream For the past five years, Ottawa Riverkeeper volunteers have been heading out to collect water samples during nasty weather, measuring the impact of road salt on urban creeks.

During blustering winter snowstorms, @ottriverkeeper.bsky.social volunteers have been bracing the cold to find out how much road salt is in local waterways, and their data is changing how Ottawa and Gatineau use road salt.

Looking east from Union Street bridge to the FishPass facility on the Boardman Ottaway River in Traverse City, Michigan. Fish sorting channel will be on the left; natural flowing river on the right.

Looking north at water flowing over the labyrinth weir, part of the FishPass facility on the Boardman Ottaway River in Traverse City, Michigan. Workers are watching a crane removing the barriers in the river to restore the flow. They'll be closing off flow on the northern section to begin work on the fish sorting channel.

A crane doing the heavy lifting to dismantle the barrier on the south side of the Boardman Ottaway River at the FishPass facility.

Enjoyed tour of #Fishpass yesterday. Removing barrier & water flowed over labyrinth weir for the first time! Shifting work to north side of river to begin work on fish-sorting channel. Visit www.glfc.org/fishpass.php for info & webcam views. Globally significant project here in Traverse City. Cool!

#IAGLR25 had a lot of great science to share, but with concurrent sessions it's impossible to catch them all in realtime. Now you can catch up on the one's you missed, as talks are available online for attendees.

We are still buzzing from our event with @janegoodall.org!!

We had so many students join in and get a chance to ask Jane questions about her life and experiences in conservation.
