Sébastien Lavanchy

Aboard #FOREL in Greenland, @EPFL engineer Sébastien Lavanchy (SENSE unit, led by @ChappellazJ ) is deploying #SubOcean, a smart probe measuring methane in meltwater. 🎥 Richard Mardens / FOREL Watch the full reel here 👉 instagram.com/reel/DMP6TiWBL… #FOREL2025 #EPFL

The Nov. storm that brought plenty of snow to 🇨🇭, also brought record waves to LéXPLORE! Two records in our wave data set were broken within 24 hours. For how that impacted the lake below the surface, check out LéXPLORE Letters #60: lexplore.info/lexplore-lette…. 🙏📝@martin_wegmann

Ocean and atmosphere research in SW Greenland in full swing aboard RV Sanna! We are precisely aiming to better understand the role of melting ice on biological productivity, GHG fluxes and aerosol production @SwissPolar @_CARVICE_ @epflENAC @ISTE_UNIL @usys_ethzh

As part of the GreenFjord project (greenfjord-project.ch), 7 scientists are on board FOREL to better understand interactions between glaciers and the ocean in fjords of SW Greenland. photo:julien.girardot.photography @jaccsa @SwissPolar @unil @FGSE_UNIL @ETH_en @EPFL @ChappellazJ

After days of searching for ice-free passage, FOREL finally arrived at Narsaq. The GreenFjord science project (​greenfjord-project.ch ) can start now to investigate on the ice-land-ocean interface at ocean terminating glaciers. Julien.girardot.photography

The Forel Heritage Association thanks the Cité de la Voile and Lorient for their welcome. May this expedition be a success ! jugirardot.com @villarsinstitute @jaccsa @fgse_UNIL @SwissPolar @ChappellazJ @EPFL @unil @ETHZurich100110 @philbenthos @universitelaval

Son nom vient de François Alphonse Forel, pionnier de l'étude des lacs et initiateur de la première expédition au Groenland l.heidi.news/vGa

🧊Glaciers, végétation, biodiversité et population... Au Groenland, les enjeux du changement climatique sont déjà très concrets. Le Temps a eu l’opportunité de suivre des scientifiques de l’expédition suisse GreenFjord, menée par l’@epfl et @SwissPolar ➡️labs.letemps.ch/interactive/20…

La farine glaciaire, vous connaissez? Les chercheurs de #GreenFjord sondent les fjords à bord du RV Sanna pour déterminer la part de vivant et de minéral dans ces écosystèmes.

🌊Autumn has fully reached our platform. That means plenty of wind, waves and rain! Thanks to @martin_wegmann check out LéXPLORE Letters No. 33 to see some of the impacts this autumn weather had on Lake Geneva: lexplore.info/lexplore-lette…

Come be our new professor in water and wastewater chemistry at EPFL! epfl.ch/about/working/…

Coming out of a very warm early September, the surface water layers of Lake Geneva are still much too warm for the season. Check out LéXPLORE Letters No. 29 for more details: lexplore.info/lexplore-lette…

One of our last stations less than 5km away from Qajuuttap Sermia’s outlet #GreenFjord #RVSanna

aaaand here's the marine cluster team of #GreenFjord together with the fantastic crew of #RVSanna @GCRC_GINR

Doing science at sea sometimes requires patience and engineering! @ChappellazJ trying to fix the subocean in-situ methane probe with some remote support! @SwissPolar @epflENAC #GreenFjord

Ever wondered how one can (hopefully) measure pico-level dissolved trace metal concentrations sampling seawater onboard a ship made of TONS of steel? You build a custom made bubble with ultra-filtered air! Masterpiece by Christel Hassler! #GreenFjord @geotraces

Slowly getting ready for departure! We are interested in better understanding the consequences of glacier melt on the circulation and biogeochemistry of SW Greenland fjords #GreenFjord @SwissPolar @FGSE_UNIL @ELE_ETHWSL @NisotopesUCT

After a few battery problems Thetis is finally back to record all things Lake Geneva ! And to play in the waves after finishing his profile. Go check out the last LéXPLORE Letters issue #25 to see what the lake has in store for us! lexplore.info/lexplore-lette…

A technician position is open at the limnology centre @epflENAC to help us take care of the amazing @LexploreLeman research platform on #lakeGeneva! lexplore.info Apply if interested, or share to potential candidates 🙏 recruiting.epfl.ch/Vacancies/2977…
