“We need to celebrate World Lake Day by acknowledging the benefits we derive from lakes, and then by returning the favour by taking action to ensure that our lakes remain healthy” John Smol, @sjcfishy.bsky.social & @sapnasharma.bsky.social reflect on #WorldLakeDay: bit.ly/45VwrGW

You are invited to submit a session to the 2026 Joint Aquatic Conference of the @iaglr.bsky.social and @Society of Canadian Aquatic Sciences (SCAS-SCSA), and hosted by @experimentallakes.bsky.social !!! Check out the call for sessions at: iaglr.org/iaglr-scas26... - Deadline: September 19.

I’m watching a live stream

At the American Theater in Canton NY. Small acts of resistance are resistance, too.

From friends, at a water festival in Lyon, France.

Beloit, WI revitalized its waterfront and chose this way to celebrate it: by bringing to life Georges Seurat's "A Sunday Afternoon on the Island of La Grande Jatte."

Happy Summer #Solstice 2025 - today on the TransCanada Highway outside of Banff, Alberta. Wet snow today - tomorrow daylight period gets shorter…..🧪

Setting up 24 x 1,400-L tanks contains St Marys River water, sediment and plants. Seen is high level light crude oil addition (time zero). Observations of biota (eDNA, phytoplankton, zooplankton, benthic inverts, and fish behavior) to follow. Funded by NRCan - MPRI project @algomau.bsky.social

If you need a breather from all this bullshit, here's a photo of Earth. From Saturn. We're that slightly brighter star at centre right.

Looking forward to tomorrow’s jump into Lake Ontario for Great Lakes Day celebration. The Great Lakes St Lawrence River watershed is an ecosystem of Biinaagami waters. We share with millions, from many nations, this life giving natural wonder. @swimdrinkfish ⁦‪@CanGeo

NOAA's National Mussel Watch Program - which has used invasive zebra + quagga mussels to track contaminants in the #GreatLakes since 1992 - finds that PFAS are ubiquitous in the lakes, with mussels in Lake Michigan having the highest average PFAS concentrations www.bridgemi.com/michigan-env...

My first Science feed contribution. Really enjoyed the Sci-Comm session at #IAGLR25! 🧪

DM me if you are going to IAGLR and are looking to stretch your legs - and link elbows - all for a good cause!

“When we remove protections for wetlands and ephemeral streams, the devastating impacts are seen in larger bodies of water like the #GreatLakes which are the main economic driver for our region and again, the source of drinking water for 40 million people." cleanwater.org/2025/05/05/c...

Heading to #IAGLR25 and want to participate in this event (skate as player or referee - no manuscript review required)? Want to pit yourself as a coach against an undefeated Defy Cup champion coach (@mjmcncycke.bsky.social)?- then send chat to me in bsky. I’m the one wearing the stripped sweater…

What follows if we imagine rivers as having lives, deaths––& even rights? I wrote this essay about water & hope; imagining rivers “otherwise”; nature’s rights; grammars of animacy; & how our fate flows with that of rivers—& always has. It’s from Is A River Alive? www.theguardian.com/books/2025/a...

RAEON has relied on @globservingsystem.bsky.social since day one. GLOS powers data that drives safety, science & the Great Lakes economy. Cutting funding risks it all.

Lake Huron's Middle Island could help us learn about what life on Earth was like billions of years ago, before we had oxygen in our atmosphere. #GreatLakes #Evolution www.discovermagazine.com/the-sciences...

We're thrilled to share that FACETS, a @cdnsciencepub.com journal, will be joining the BlueSky community soon! Stay tuned for updates as we prepare to connect, share, and engage with researchers and science enthusiasts in this exciting space. See you soon! 🌟 #ScienceCommunication #BlueSky

Once widely found across the #GreatLakes region, wild rice (manoomin) has largely disappeared due to colonization and environmental degradation - but a new stewardship plan is centering indigenous knowledge to restore + preserve wild rice for future generations www.bridgedetroit.com/groups-fight...

The tribes already had concerns about the process, but news that the Army Corps will likely fast-track the federal permit for the pipeline tunnel was "the final straw." Story by @iprnews.bsky.social: www.greatlakesnow.org/2025/03/seve...

Eye spy: USCG Spar hanging out in Whitefish Bay. As seen from Gros Cap, Ontario, today. Still feels like winter here. #lakesuperior

I love my job! Encourage young adults to learn about the Great Lakes, provide expert speakers from across the region; guide them into the multinational treaties in the region - then divvy them up into env governance work groups and listen to them solve a problem!! @algomau.bsky.social #greatlakes

Today is #WorldWaterDay. A day to honour, love and advocate for life-giving water. #WaterIife

With over 2.8 million anglers in the provinces and states surrounding the Great Lakes, we know how important the water is to our fisheries. #WorldWaterDay

Happy World Water Day! As part of this celebration, I attended the first Anishnabek Nation Water Consortium, held March 18 & 19 in Little Current, on Manitoulin Island. Learned a lot about our reciprocal responsibilities with #water. #anishnaabe #GreatLakes

CGLR announces that : Mark Fisher, CEO of the Council of the Great Lakes Region, to become the first President of the Canada Water Agency! Congratulations!

Beautiful landscapes abound. Enduring an afternoon outing on the east coast of Lake Superior. #greatlakes

So,... on the theme of the #gulfofmexico, today I joined Wikipedia in order to edit "The United Lakes of America, also called the Great Lakes of North America, are a ...." and "The United Lakes of America are the largest group....". #greatlakes

Great Lakes Now contributor @garyglx5.bsky.social was featured in a CBC Radio segment that looked at the question of water sovereignty — and whether Canada is ready to protect its resources. Listen to it here: www.cbc.ca/listen/live-...

Many thanks to my colleague @1pantunes.bsky.social for the help and good chat!

Very excited to see some of my PhD work published after much (much) too long! Using mesocosms and controlled ponds, we manipulated ice cover conditions and looked at the corresponding DO, light, and chlorophyll-a regimes. aslopubs.onlinelibrary.wiley.com/doi/10.1002/...

[RFP Please repost] The IJC GLRO (@IJCsharedwaters.bsky.social) is currently soliciting bids to undertake a pilot project of the Great Lakes Early Warning System. Interested bidders should contact [email protected] for a copy of RFP and to confirm intent. Proposals due Feb 4 2025, 11 am EST.

Ten years ago, scientists discovered ancient hunting camps beneath Lake Huron. Now, DNA samples from a submerged peat bog could produce more revelations about the prehistoric #GreatLakes 🌊 Story by @bridgemichigan.bsky.social: www.greatlakesnow.org/2025/01/a-gr...

As we head into 2025, and northern temperate lakes start to freeze, be sure to check out our manuscript on the environmental and societal consequences of lake ice loss! www.science.org/doi/10.1126/...

Another year, another record temperature... where will it end?

Good morning solstice sun from Baawaating- Saint Sainte Marie, Ontario!

A 92-year record of ice phenology is helping show how lakes worldwide could change in coming decades, thanks to new #AGUPubs research from @isabellaoleksy.bsky.social, @instaar.bsky.social and @richardsond.bsky.social.

“Clean up on isle Ottawa…”. (psst…@ottawacity.bsky.social) Noticed a salt dump that ought be gathered up. We know that salt makes slippery sidewalks safer but those spruce trees are stuck near this. Kindly clean up. Merci bien.

This what happens when an ice free #LakeSuperior happens to have very warm surface water at this time of year when cold winds blow from the west. This is Sault Ste Marie, ON. (nice sauna if you can get to it.)

Always fascinating to consider large scale extinctions (article in Eos by @agu.org). Do the same responses occur at other temporal and spatial scales? x.com/agu_eos/stat...

I am looking for a PhD student to start in fall of 2025 at MSU. Potential topics include trait-based approaches to plankton community resilience, temperature effects on communities, harmful algal blooms and many others. Please get in touch if interested. More info: www.kl-lab.group.

We (Algoma University, Lake Superior State University and several other institutions) are studying the impact of petroleum spills in the #GreatLakes with an emphasis on the #winter condition. See image ALT for more details. Thanks to NRCan for funding support. N
