EBUS Webinars

EBUS Webinars was created and run by a group of early-career ocean scientists between 2018 and 2021 to make the scientific knowledge exchange on the ocean's eastern boundary upwelling systems (EBUS) more inclusive and sustainable. The webinar series hosted 37 online talks.

In EBUS, the upwelling of nutrient-rich water to the sunlit surface results in high primary production and fish catch. Thus, these regions are of huge socio-economical importance. EBUS Webinars aimed to foster regular and effective exchange between the physical, biogeochemical, and biological scientific communities to better understand how climate change will impact EBUS.

The project has ended, there are no upcoming talks.



Soeren Thomsen

Soeren is an EU funded CNRS postdoctoral fellow at LOCEAN in Paris. For his interdisciplinary research, he carries out and analyzes observations and numerical model simulations focusing on the Peruvian and West African upwelling systems and oxygen minimum zones. Soeren initiated the EBUS Webinars project in 2018. He now coordinates all efforts, contributes by moderating sessions, and also organizes the streaming in his lab.


Elisa Lovecchio

Elisa is a postdoc at the National Oceanography centre of Southampton (NOCS). During her PhD at ETH-Zurich, she studied the lateral redistribution of organic carbon from the N-W African EBUS to the open ocean through coupled physical-biogeochemical ocean simulations. In her current project at NOCS, she uses glider and model data to study the mesoscale influence on export fluxes in the Benguela EBUS. Elisa moderates the EBUS Webinars, and created this website.


Véra Oerder

Véra is a postdoctoral researcher at the Escuela de Ciencias del Mar from the Pontificia Universidad Católica de Valparaíso (PUCV), Chile and belongs to the Millennium Institute of Oceanography (IMO, Chile). Her main research field is the Peru-Chile EBUS and she works with numerical models (both atmospheric and oceanic). She collaborates with the EBUS Webinars scheduling and moderation.


Eike Koehn

Eike is a PhD student in the department of Environmental Systems Science at ETH Zürich in Switzerland. He mainly uses regional ocean models to study the biogeochemistry in the EBUS of the Pacific, with a focus on extreme events in the Peruvian upwelling system. He contributes to the EBUS Webinars series by moderating sessions and organizing the streaming of presentations in his lab.


Suresh Iyyappan

Suresh is a scientist at the National Institute of Oceanography, Goa, India. Using a linear ocean model, he investigated the processes controlling the sea-level variability along the west coast of India that hosts the only EBUS in the north Indian Ocean. He is also interested in understanding how the ocean dynamics controls the biogeochemistry, using both observations and coupled physical-biogeochemical models. Suresh organizes and moderates in the EBUS Webinars.


Parvathi Vallivattathillam

Parvathi Vallivattathillam is a postdoctoral associate at the Center for Prototype Climate Modeling (CPCM) at New York University Abu Dhabi. In her research, she explores the bio-physical interactions in the Indian Ocean and their response to climate change using numerical models. She contributes to the EBUS Webinars by managing the website and sourcing speakers.


Khassoum Correa

Khassoum is a PhD student

at LOPS (UBO-BREST) and 

LPAOSF (UCAD-DAKAR). Using remote sensing products he 

studies the response of phytoplankton functional groups to the dynamics of the Senegalese plateau. He contributes to the EBUS Webinars series by managing the YouTube channel and organising 

the lab viewing at his university.


Maria-Elena Vorrath

Maria-Elena Vorrath is a DAAD postdoctoral fellow at LEMAR, Brest,
France. She investigates marine trace metal cycles in the Pacific and
Indian Ocean. In the past, she studied particle fluxes in the Benguela
Upwelling System and used organic biomarkers to reconstruct past sea ice
in Antarctica. Fascinated by the biological carbon pump she enjoys
interdisciplinary research approaches in marine science. She contributes
to EBUS Webinars by managing the YouTube channel.


“EBUS Webinars represent the best opportunity to share, and learn about, the most current research on EBUS - this is the only place where all EBUS researchers from around the world can regularly get together.” Monique Messié, Monterey Bay Aquarium Research Institute, CA, USA

“I watch EBUS Webinars to compare these productive ecosystems in the context of climate change and fisheries pressures.” Jorge Tam, Instituto del Mar del Perú Callao, Lima, Peru

“Thanks for providing these EBUS Webinars! I enjoy learning about other EBUS research and connecting with researchers around the world.” Caitlin Amos, University of Georgia, USA

“I am watching because I am working on the biogeochemistry of the eastern South Pacific and North Atlantic upwelling systems!” Pierre-Amaël Auger, IRD, Brest, France

“Webinars are a wonderful tool, it was before the global pandemic and it is all the more now. The EBUS Webinar group makes it easy to stay informed on what people are doing and it's a unique way to interact, especially for young scientists in countries where research is not as developed and funding is scarce. It allows to avoid redundancy and fosters collaboration.” Alice Pietri, FONDECYT-IMARPE, Lima, Peru

“It’s an awesome and unique opportunity to be able to attend EBUS presentations of speakers from around the world. We made it a habit to follow them up with a discussion on the topic in our lab and a cold beer.” Carolin Loescher, University of Southern Denmark, Odense, DK
