The Brest workshop on environmental physics and signal processing (EPSP) aims at bringing together first-line scientists from different domains: physics, mathematics, signal processing, oceanography, climate, remote sensing, etc in order to facilitate discussions and promote a better understanding of the environment. The first edition of EPSP is devoted to ocean and climate science and presents four main topics, each one with two invited speakers:

• Lagrangian ocean dynamics

• Inga Koszalka (Stockholm University)

• Erik van Sebille (Utrecht University)

• Causality relationships in signal processing

• Nicolas Brodu (Inria Bordeaux)

• Milan Palus (Czech Academy of Sciences)

• IA and ocean: downscaling and interpolation

• Daniele Ciani (National Research Council of Italy)

• Julien Le Sommer (National Research Council of France)

• Multiscale modelling and signal processing methods

• Jordi Isern Fontanet (National Research Council of Spain)

• Ivica Vilibic (Ruđer Bošković Institute)

The workshop is structured in two talks per topic followed by scientific discussion and its vocation is to be a catalyst for new collaborations and to promote interactions between scientists from different fields.

Organizing committe:

• Lucas Drumetz (IMT Atlantique)

• Carlos Granero (IMT Atlantique)

• Ronan Fablet (IMT Atlantique)

• Pierre Tandeo (IMT Atlantique)

The full program with the titles and abstracts of the presentations is now available at this link.

Venue

The Brest workshop of Environmental Physics and Signal Processing will take place between 19th and 21st June 2023 at Technopole Brest Iroise. Seminars will take place at the amphiteater of IMT Atlantique (see here for a map of the campus).

Invited Speakers

Erik van Sebille

Erik van Sebille is a physical oceanographer at Utrecht University in The Netherlands. His research focuses on how ocean currents transport heat, nutrients, marine organisms and plastic litter. He builds computer models to simulate the transport of this ‘stuff’ in the ocean. He is the lead developer of the OceanParcels code, an open-source framework for Lagrangian Ocean Analysis. He led two large collaborative review articles, on the fundamentals of Lagrangian Ocean Analysis in 2018 and on the physical oceanography of floating plastic in 2020. He is also affiliated with the Freudenthal Institute, where he leads research into the effectivity of Public Engagement activities, within the context of Open Science.

Inga Koszalka

I am Associate Professor of Coastal Oceanography at the Department of Meteorology, Stockholm University (MISU) and a research fellow (Baltic Sea Fellow) at the Stockholm University Baltic Sea Centre. The focus of my current research is on mesoscale- and regional ocean circulation, its variability as well as ocean interactions with atmosphere, cryosphere and biosphere. In my research, I employ observations, idealized ocean models and regional ocean model output, Lagrangian analysis and modelling, statistical methods, and theory. My studies often address ocean turbulence and turbulent dispersion which are not well understood yet important element of the climate system and require hollistic and novel approaches. My study domain considers primarily the Atlantic Ocean, the Nordic Seas, Greenland shelves and fjords as well as the Baltic Sea where I started my oceanographic studies as an undergraduate student. I have a broad background and scientific interests spanning various topics of Geophysical Fluid Dynamics.

Nicolas Brodu

My research domain is the study of complex systems, and more specifically building new tools for their investigation. This includes exploiting statistical properties, modeling non-linear dynamics, pattern detection at multiple scales, etc. More generally, I seek to extract most information out of experimental data, and I investigate how that information can be used to build better models of their dynamics. I favor multi-disciplinary applications and in particular the study of natural sciences and the environment.

Milan Palus

M. Paluš is a Senior Researcher in nonlinear dynamics and complex systems theory, namely in analysis of (multivariate, multiscale) time series recorded in complex systems, and an expert in applications of methods from information theory and statistics in nonlinear signal analysis. He pioneered applications of information theory for the detection of causality in time series. In this area, he is an author or co-author of influential papers with more than 1200 citations according to the Web of Science. Further interests include the detection of structures in complex datasets, synchronization, predictability, nonlinearity, nonstationarity, fractality, chaos. He has experience in interdisciplinary cooperation with results published in prestigious journals such as Nature Neuroscience or Nature Communications. His works have been applied in diverse fields from physics, geophysics, meteorology, climatology, air pollution, through electrophysiology and neuroscience to finance.

Daniele Ciani

Daniele Ciani is a researcher in marine sciences at the National Research Council of Italy (Institute of Marine Sciences). He holds a master degree in physics (University of Rome, IT) and a PhD in physical oceanography (University of Brest, FR). His education is based on geophysical fluid dynamics and environmental remote sensing. His main interests are mesoscale and submesoscale ocean circulation, eddy dynamics and ocean surface currents/sea surface temperature remote sensing. He was/is involved in ESA projects for the monitoring of the ocean surface (ESA-CIRCOL, ESA-WOC, ESA-RACE), for the development of future satellite missions (ESA-CIMR, ESA-Earth Explorer 10 Harmony) and in R&D activities within the Copernicus Marine Service Multi Observations Thematic Center (MOB TAC). Recently, he joined the Group of High Resolution Sea Surface Temperature (GHRSST) Science Team.

Julien Le Sommer

I am physical oceanographer, interested in cross-scale interactions in the ocean and the climate system. I am working for CNRS in the MEOM group at IGE (Grenoble, France). My work involves designing and analysing realistic ocean model simulations that describe oceanic physical processes over a wide range of space and time scales.

Jordi Isern Fontanet

My main interests are the understanding of ocean turbulence and its role in Earth’s climate, with particular attention to the upper layers of the ocean between sub-mesoscales and mesoscales. My research combines theoretical developments with the analysis of ocean numerical models and ocean observations, such satellite data.

Ivica Vilibic

Ivica Vilibić is senior research scientist at the Ruđer Bošković Institute, Croatia. Ph.D. in ocean sciences obtained in 2002. His research interests cover: sea level changes and variability - including meteotsunamis, ocean climate changes and projections at coastal scales - including (sub-)kilometre-scale numerical modelling, marine biogeochemistry, coastal hazards, and other. He leaded or participated in various international (EU FP5 to Horizon Europe, USA NOAA, Interreg), bilateral (HR-USA, HR-IT), and national projects. He has published more than 150 peer-reviewed scientific papers, and presented more than a hundred of communications to international meetings. Reviewer to a hundred of articles and research projects (USA NSF, Canada, Israel, Estonia, Italy, Croatia). Acted as a national or institutional representative or expert group member in Intergovernmental Oceanographic Commission (https://ioc.unesco.org), EU Programme Committees, BlueMed Initiative (www.bluemed-initiative.eu), European Network of Research Integrity Offices (ENRIO, www.enrio.eu), European Marine Board (EMB, www.marineboard.eu), and other.
