First saw this in my gr 8 sci text. Changed my perspective of oceans from featureless swaths of empty blue space between continents to a hidden world of diversity and wonder. Nice to finally learn about it's origins! Thanks Marie, Bruce, Heinrich, @_david_ho_, and @geosuzanne

[David Ho @_david_ho_]

A few people asked about the origin of this map. Every geoscientist knows it's from Marie Tharp and Bruce Heezen (painted by Heinrich Berann). This piece from @geosuzanne is a good place to learn some history.

It's not gracious, it's actually the law.

[Area Woman @heyjezka]

Stopping for a pedestrian who’s waiting to cross when you don’t have a stop sign isn’t the gracious gesture you think it is. Just go! There’s already a system in place here and it doesn’t need an override.

[David C @dwcapelle]

This is a huge loss. David gave me and so many others a chance to pursue Arctic research. His legacy will continue to do so for generations, even though he's gone. So grateful to have had the chance to know and work with him. My condolences to his family, friends, and colleagues.

We're extremely sad to share the news of the passing of Dr. David Barber. He was one of Canada’s most influential and accomplished Arctic researchers and will be dearly missed.

Our hearts go out to his family and friends.

For a century and a half, the world considered John Tyndall as the person who discovered the warming potential of carbon dioxide and water vapor—even though he published his findings three years after Eunice Foote. #IWD2022 https://t.co/xGvQEXJlIj

@polaur_ Finally!! 😅 Congrats Laura!

@carabonate @UConnMarineSci @UConn Looks amazing! Congrats Cara!

Ever wondered what it's like to live aboard a #research vessel? Our #Arctic Research Specialist, Maude Durand, found out firsthand during the #JamesBay2021 expedition, and has shared her experience in our latest blog! Read it now: https://t.co/rLPN1HoX4y #expedition

here's the GPS track from part of that cruise, showing the ship going back-and-forth every time we got stuck, to try and ram through the thick ice.

[David C @dwcapelle]

This was fun to be part of. Nobody on this expedition had seen mobile sea ice like this. Tens of meters thick and covered in sediment ranging from smaller than sand to small boulders. Too thick even for our icebreaker at times. Felt like trying to break through rock

[Dave Babb @dave_babb]

Just shy of 4 years ago, my colleagues sampled this lunar looking ice surface in southern Hudson Bay. The ice was covered in sediment & too thick for the Amundsen to break through. This thick 'dirty' ice hadn't been observed before in Hudson Bay, so we dove into it.

Big kudos to Madison for leading this massive collaboration! No easy task!

Great job by Kate publishing her undergraduate thesis using a novel incubator system to measure primary production and respiration in #LakeWinnipeg every ~30 mins on the #Namao. Highest PP was found in low-chlorophyll waters (early bloom), and net heterotophy in chl-rich waters.

Great work by Rachel publishing her undergraduate thesis - the first measurements of #LakeWinnipeg #methane (CH4) flux. Lakes are important natural sources of the greenhouse gas CH4 to the atmosphere, and emissions are expected to increase with continued #eutrophication

[David C @dwcapelle]

@Cmdr_Hadfield Amazing. The atmosphere looks as thin as the film of a soap bubble. Where life as we know it lives...

[David C @dwcapelle]

Great work leading this by Mohamed! I was surprised to see few signs of CO2 outgassing so soon after ice retreat - suggests ice melt and ice algae offset CO2 that builds up under ice during winter

[Mohamed Ahmed @MohamedMMAhmed]

Check out our recent paper published in @elementascience titled "Widespread surface water pCO2 undersaturation during ice-melt season in an Arctic continental shelf sea (Hudson Bay, Canada) ". The key findings are listed 🡇🡇 1/8

#MBFire risk remains very high across parts of southern & central MB due to extremely dry conditions.
