🌊🌊New study shows how changes in the Malvinas Current shape phytoplankton blooms on the Patagonian shelf (SWAO), linking offshore circulation pathways with year-to-year shifts in marine productivity and fisheries-relevant ecosystems.🌊
New paper out! 🌊 Using 20 years of satellite data, we identify 5 phenoregions and show the Patagonian Shelf Break as a dynamic mosaic of seasonal productivity pulses — a global hotspot shaping marine ecosystems and fisheries.🌊

#EcosDe2Cañones
🌊En “The southern gap in ocean microbiome science” destacamos la gran brecha geográfica en la investigación del microbioma oceánico.
Desde el sur, aportamos nuestra voz para promover colaboraciones más equitativas, fortalecer redes y construir una ciencia oceánica verdaderamente inclusiva 🌊
The #Ecosde2Cañones team collected oceanographic data to better understand how the shape of the seafloor & powerful currents influence productivity in Argentina; they will return home w/new questions & the memory of seeing life pulsing through these canyons.

🌊 Agradezco al SOI por brindarnos la oportunidad de explorar los secretos de nuestro mar: su extraordinaria biodiversidad planctónica, así como su dinámica hidrográfica y geomorfológica, desde una perspectiva verdaderamente interdisciplinaria! 🌊

into smoke, into a spiral,
into a building, a fish, a stone, a rose.

The #Ecosde2Cañones team is studying the intricate interplay of ocean features such as currents, wind, circulation, density, temperature, and salinity as they examine the exchange of energy between the atmosphere, the Ocean, and the Earth.

Fitoplancton: el bosque invisible que respira el océano 😍🌊
Estudiar los microorganismos del plancton 🔬 implica no sólo identificar sus increíbles formas, tamaños y comportamiento, sino también comprender sus pulsos de productividad 🦀🦐🐳🐠 regulados por la mezcla vertical y las corrientes oceánicas🌊🌊🚢
🌊Our group will study phytoplankton communities through taxonomic and functional analyses, pigment and toxin profiling, bio-optical traits, and genetic diversity. This research will reveal how canyon–current interactions shape nutrient fluxes and bloom dynamics along the Argentine Coninental Margin.
Our mission: to understand how bio-physical coupling drives massive phytoplankton blooms, fueled by nutrient-rich waters from the Malvinas Current interacting with transversal submarine canyons along the shelf break.

😍🌊🚢Excited to join the Falkor (too) expedition: A Tale of Two Submarine Canyons! From Sep 28 to Oct 30, 2025, we’ll be onboard this amazing scientific adventure exploring the outer Patagonian Shelf, SW Atlantic Ocean. 🌊🔬

Hermoso trabajo Pablo! Gran equipo en esa campaña!! Felicitaciones! 😍🌊🔬🧑🎨⛵
When Chief Scientist Daniel Lauretta & #TaludContinental_IV team encountered a seafloor blooming w/these animals, he nicknamed it: beet field. While rich in color, they're not related to the ruby red root vegetable & likely a type of Anthomastus, a genus of soft corals in the family Alcyoniidae.
Octopus locomotion 🐙
We believe this warty deep-sea octopus to be in the Graneledone genus of octopuses, and ROV pilots collected this footage in the #MarDelPlataCanyon in Argentina.

ROV pilots filmed these sea spiders in #MarDelPlataCanyon during #TaludContinental_IV expedition in Argentina, where Argentine people are teaching us all how to experience the wonder of all deep-sea animals, many-legged and otherwise. 🇦🇷 Read full caption on Insta: www.instagram.com/reel/DNBy1Bx...

🌊 El mar profundo argentino cubre más del 70% del territorio marítimo nacional y alberga una biodiversidad única pero vulnerable al cambio climático. Un nuevo artículo destaca la urgencia de fortalecer el conocimiento científico y la gestión ecosistémica para su protección.🌊

Art in the seawater. We caught a massive toxic phytoplankton bloom retained for 10 days in a mesoscale eddy in the Argentine Sea. These nanodinoflagellates — Amphidomataceans — were super happy!
Happy to share our last work!!
🌊🔬A survey with two vessels in the Argentine Sea caught a massive toxic phytoplankton bloom retained for 10 days in a mesoscale eddy. Interdisciplinary approaches shed light on the biophysical coupling behind its development.🌊⛵⛵

🌊Integrative work like this by J. Cloern & A. Jassby, compiling global time series, is so valuable and needed.🌊 Glad I could contribute a drop to the ocean of what we still need to learn about aquatic systems!🌊

Ever wondered how we can track #phytoplankton across the vast, dynamic global #ocean? A new #satellite-derived dataset is making this task much easier. This blog post by the Ocean Sciences (OS) Division shares more details.
