Study reveals colonization wiped out nearly 90% of marine food ecosystems in Vancouver's coastal waters | CBC News A new research partnership between the University of B.C. and Tsleil-Waututh Nation indicates impacts of colonization, including smallpox, overfishing and industrialization, destroyed nearly 90 per ce...

Canadian wetlands are treasures that deserve protection Canada is home to a quarter of the world’s remaining wetlands. Despite decades of efforts, wetlands continue to be under threat around the world.

COP15 of the Ramsar Convention starts today. Here in Canada we have the privilege of being home to a quarter of the world's remaining wetlands. Let's not forget what a treasure they are.

If you want to reminisce about some #EGU25 inland water GHG highlights, I wrote a little something for the BG division blog! ✍️

Yeah… the EGU ones seem to appear automatically, maybe there is a way to get rid of them?! Although I’ll take ‘em to beef up my meagre publication list 😂

We found some mixed results: no observed effect of the impoundments on leaf litter decomposition, a longitudinal effect on organic matter stocks, and a local effect of high diffusive CO2 and CH4 emissions downstream of one of the two impoundments.

We measured upstream and downstream of two small impoundments like this one, as well as at other reaches along the Tarentaine river network in France.

Small Water Impoundments Have Local and Longitudinal Impacts on Carbon Cycling Along a River Network Damming may be one of the most significant anthropogenic modifications fragmenting river networks. Damming alters the transport and processing of coarse particulate organic matter (OM), hence influen...

Our article about the local and longitudinal effects of small water impoundments on riverine carbon cycling is out now in River Research and Applications @tdatry.bsky.social @rsarremejane.bsky.social onlinelibrary.wiley.com/doi/full/10....

Visited some lowland peat ditches in East Anglia with @peatymike.bsky.social to collect CH4 ebullition measurements for the LowlandPeat3 project. Some of the ditches were dry, others covered in duckweed, and we even spotted a fish in one!

A big tour of fenland ditches with @tksilver.bsky.social today for the Defra-funded Lowland Peat 3 project. Samples collected for dissolved GHGs and dissolved organic carbon, and 24hr chambers deployed to capture total CH4 emissions.

No advert out yet, but I will recruiting a 2yr postdoc, start date autumn 2025, at @livunigeog.bsky.social soon. Lowland and upland peatlands, GHGs, DOM and water chemistry. Plenty of fieldwork. Feel free to drop me a DM or email if you might be interested, and please spread the word.

Lovely to be once again back in Uppsala. Visited five rewetted/restored peatlands today to measure aquatic GHG emissions with @laurabaugh94.bsky.social & @tksilver.bsky.social

An excellent few days in Aarhus, Denmark for the Beyond the Surface symposium on inland water greenhouse gas emissions! So many inspiring talks and discussions

Stoked to be kicking off a week of science at EGU in Vienna! #EGU25

Laura, wearing a black ball cap, light blue long-sleeved top, black trousers, and hiking boots, is standing on a boardwalk in a peatland and smiling at the camera. There are trees in the background. Behind Laura is a pool, and to the left are a couple of floating chambers stacked up which are used to measure greenhouse gas fluxes from peatland waterbodies.

The second recipient for the April round of #PeatNeeds is Laura Baugh (laurabaugh94.bsky.social). Laura is interested in GHG fluxes from waterbodies in rewetted peatlands, with a specific focus on methane. 1/2

Announcement of projection of documentary "Salbia, a salinity threat to the river Gambia" during the EGU25 conference in Vienna. This will take place 1st of May 2025, 18:10, room E1 at the Conference Center.

We went to the #Gambia to evidence how rising salinity in the river is affecting both local communities and the ecosystem, and @milevafilms.bsky.social made a documentary about it.
It will be shown for the first time to the public next week at @egu.eu #egu25.
Don't miss it if you are there!

A week until EGU25. My group from @livunigeog.bsky.social
will be there presenting our peatland research.

First up, @tksilver.bsky.social, Monday 15:00, Room 2.23, will be talking about UK lowland peatland management and ditch GHGs.

Our new paper, led by colleagues at the Chinese Academy of Sciences, out now in early view.

"Agricultural ditches and stream networks are overlooked hotspots of carbon emissions"

@livunigeog.bsky.social

It's Ditchmas Eve! Tonight @tksilver.bsky.social and I will welcome the early arrivals for our symposium happening tomorrow:

"Towards net zero: accounting for and mitigating greenhouse gas emissions from ditches and canals".

Looking forward to lots of ditchey talk. @livunigeog.bsky.social

Ditches and canals are a big, yet overlooked, source of greenhouse gas emissions – new study The global length of ditches is unknown, but these unassuming bodies of water play a significant role in the global climate crisis.

The global length of ditches is unknown, but these unassuming bodies of water play a significant role in the global climate crisis.

And here's our article with @tksilver.bsky.social about our new paper.

Climate, trophic state, and drying influenced N2O emissions from ditches, while CO2 emissions had complex drivers difficult to disentangle at the global scale

Including ditches in global inland water emission budgets (where they are currently omitted) would increase CO2 emissions by 0.6%–1% and N2O emissions by 3%–9%

We synthesized global ditch GHG data and found that ditches emit notable CO2 and N2O--at higher rates than ponds, lakes and reservoirs

The Importance of Ditches and Canals in Global Inland Water CO2 and N2O Budgets We synthesized data across global climate zones to show, for the first time, that global ditches and canals emit notable amounts of carbon dioxide and nitrous oxide, at higher per area rates than pon...

More Fenland ditch GHG sampling today with @tksilver.bsky.social for the Defra-funded Lowland Peat Project 3. Lots of mud today, and sadly no "nice" ditches; just bleak & dismal.

A long day in the East Anglian Fens with @tksilver.bsky.social taking samples of ditch greenhouse gases for the Defra-funded Lowland Peat Project 3.

Excited to be able to share this paper soon! Great collaborative effort with an awesome group of co-authors! 🤩
