En avril 2017, une équipe internationale de scientifiques part étudier les écosystèmes inconnus d'un mont sous-marin reculé du sud-ouest de l'océan Indien à bord du MARION-DUFRESNE, navire océanographique français opéré par l'Institut polaire français IPEV. Le Banc WALTERS, une montagne submergée située au-delà des juridictions nationales, est étudié par les scientifiques du Muséum National d'Histoire Naturelle et de l'IRD (Institut de Recherche pour le Développement) pendant l'expédition de 26 jours. 'La Dernière Frontière' est un documentaire produit par l'UICN en partenariat avec et grâce au soutien financier du Fonds Français pour l'Environnement Mondial (FFEM) qui relate cette expédition et ses enjeux. Il appelle à plus de science pour la haute mer, et une meilleure gouvernance des eaux internationales. Ecrit par James NIKITINE, il est réalisé par James NIKITINE et Fabiano D'AMATO, avec une narration d'Alain GHAZAL et une musique de Woodkid. La haute mer constitue #LaDernièreFrontière à nos connaissances. Pour plus d'informations rendez-vous sur le site: https://www.iucn.org/science4highseas

Strange and unusual deep sea creatures revealed by CSIRO scientists off north-west WA.

Around 60 years ago, marine scientists on an armada of ships from 14 countries combined their efforts to explore the largest unknown area of earth, the deep waters and seafloor of the Indian Ocean.

Kenya needs tight laws to protect its rich ocean wealth.

Marine scientists are using portable ship-borne aquaria in the search for heat-resistant corals that could survive warming ocean temperatures caused by climate change.

Twenty three scientists set sail on a research vessel off the eastern coast of India (14 March 2021) on a three-month-long quest to map the genomic and proteomic diversity of the Indian Ocean.

CSIRO's research vessel (RV) Investigator departed Darwin for a 45-day voyage of biodiversity discovery in the tropical waters of the Indian Ocean.

* Enhancing the readiness of Western Indian Ocean researchers to use marine robots. * Exposing LDCs to robotics increases readiness for technology transfer. * Artisanal fishing communities respond positively introduction to new technologies. * Further investment and commitment at both national and regional levels is required. * Scalable funding options are available to accelerate regional development.

SONNE Expedition SO305 Creates First Comprehensive Dataset on Biogeochemistry.

Accurate estimation of air-sea fluxes is essential for advancing ocean modeling, observational studies, and understanding air-sea interactions. To address this need, the Indian National Centre for Ocean Information Services (INCOIS) developed and deployed a Flux Reference System (INCOIS-FRS) onboard ORV Sagar Nidhi. This article provides an overview of the system, its components, data acquisition methods, flux computation techniques, and preliminary results. The INCOIS-FRS integrates an Eddy Covariance Flux System (ECFS) and an Automated Weather Station (AWS). The ECFS collects high-frequency (20 Hz) data to directly estimate the latent heat flux (LHF), sensible heat flux (SHF), and momentum flux (τ) using the Eddy Covariance (EC) method. The AWS records meteorological and oceanic variables at 1 Hz, enabling flux estimates using the COARE 3.5 algorithm. A spectrally flat Class-A pyranometer and a pyrgeometer provide climate-grade measurements of downward shortwave and longwave radiation, which, combined with EC-derived SHF and LHF, yield the net heat flux. This article presents preliminary results inferred from data collected by INCOIS-FRS during a cruise in the Arabian Sea from 1-16 July 2023. Data from this system are useful for validating model outputs and satellite observations, refining flux parameterizations, marine boundary layer studies, and improving air-sea interaction models. INCOIS-FRS represents a first step toward equipping more oceanographic platforms, both crewed and uncrewed, with flux reference units. Future plans include expanding such deployments to enhance observational coverage and support research on air-sea fluxes across the Indian Ocean and other regions.
