• 29/05/2014 - 13/07/2024: French-Vietnamese PLUME campaign.

The French-Vietnamese oceanographic campaign PLUME (Particle transport along river pLUmes and their iMpact on coastal ecosystems off ViEtnam), will be held in Vietnam from May 28 to July 11, 2024. The PLUME cruise is taking place in an extremely solid French-Vietnamese partnership and programmatic context. Managed by the French National Research Institute for Sustainable Development (IRD) and the Vietnam Academy of Science and Technology (VAST), the campaign is conducted aboard the research vessel Antea of the French Oceanographic Fleet (FOF), operated by IFREMER (French Research Institute for Exploitation of the Sea) with the support of the French National Centre for Scientific Research (CNRS).

PLUME aims to better understand and quantify the transport of water, particles, natural and anthropogenic materials, their mixing, evolution, distribution and fate along the river-estuary-ocean continuum, as well as their impact on the coastal area, mainly around Vietnam's three largest river systems, namely the Red River, the Mekong River, and the Saigon-Dong Nai river system, during the wet (rainy) season.

This oceanographic campaign represents the highlight of the celebrations in Vietnam of the 80th anniversary of IRD.

• 5-8 December 2023 : The first regional workshop on "Southeast Asia environmental systems" organised at the USTH-VAST by LOTUS and the SOOT-SEA IRN, in partnership with their partners from the CARE IRN, the JEAI WATER-4C and the IRN PASSPORT-2C, was held in Hanoi from 5 to 8 December, with the support of the IRD and the USTH.

The aim of the workshop was to bring together scientists from different disciplines, methodologies and fields working on common issues (climate, pollution, continent-ocean continuum, marine and coastal ecosystems, etc.), in order to encourage the emergence and construction of collaborative research and training projects on a regional scale.

This interdisciplinary workshop brought together 80 participants from laboratories and institutes in Vietnam, Cambodia, Thailand and France, who presented their work on subjects relating to the evolution of regional systems and coastal, deltaic and marine environments in the face of various natural and anthropogenic factors of variability: estuarine and coastal hydrodynamics, sea-level rise, delta subsidence, sediment transport, fate of contaminants, regional and urban climate, vulnerability and adaptation of populations.

Satellite altimetry techniques have been developed for over 25 years, providing a huge amount of information about the ocean, coastal surfaces, hydrology and ice surfaces. In an era that sees a wealth of information coming from nadir, SAR and, in a couple of years, interferometric altimeters., it is important to know what information is available, how to use it, and what are their limits. In this perspective, we organized a 3 day altimetry course at USTH, Hanoi, from April 16th to April 19th 2019 with 15 participants from public and private Vietnamese institutions
