Oceans under climate stress: AI, satellites, real-time data hold key to protecting global fisheries

Kochi, Nov 5 (UNI) Climate change is rapidly reshaping the world's oceans, with rising sea temperatures, marine heatwaves, shifting fish populations, coral bleaching and harmful algal blooms emerging as major threats to marine biodiversity, fisheries and the livelihoods of millions of coastal people, marine scientists have warned.
Calling for a globally integrated, technology-driven ocean monitoring network, experts stressed the need to harness satellite remote sensing, artificial intelligence (AI), oceanographic observations, climate models and real-time in-situ data to detect environmental changes, forecast extreme marine events and provide timely early warnings to fishing communities.
The warning came at the inaugural session of the three-day international TREVOR SAFARI (Societal Applications in Fisheries and Aquaculture using Remote Sensing Imagery) symposium, hosted by the ICAR-Central Marine Fisheries Research Institute (CMFRI) in Kochi.
The international gathering has brought together more than 300 scientists, researchers and specialists from 30 countries to explore how emerging technologies can strengthen fisheries and aquaculture, improve ocean observation and address the growing challenges posed by climate change.
Inaugurating the symposium, Dr Sophie Seeyavae, Chief Executive Officer of the Partnership for Observation of the Global Ocean (POGO), UK, underlined the importance of technological innovation in improving Potential Fishing Zone (PFZ) advisories, detecting harmful algal blooms, forecasting marine heatwaves and issuing reliable weather and sea-condition alerts to fishing communities.
She emphasised that strengthening global ocean observation capabilities and building scientific expertise were crucial to enhancing climate resilience, monitoring water quality and ensuring sustainable fisheries management.
POGO has trained nearly 1,500 early-career ocean scientists from 102 countries, contributing to the development of global expertise in ocean observation, she said.
Presenting research on the impact of climate extremes on marine ecosystems, John A Gittings of the National and Kapodistrian University of Athens, Greece, said extreme climatic events, particularly marine heatwaves, were triggering unusual changes in marine productivity across the world's oceans.
The increasing frequency of storms, droughts, wildfires and heatwaves was altering the physiology, abundance, geographical distribution and community structure of marine organisms, making continuous ocean monitoring essential to identify and understand emerging changes, he said.
Scientists also highlighted the need to integrate ocean observations with weather forecasts, wave data and ocean-current patterns to improve maritime safety advisories and help fishing communities prepare for unpredictable sea conditions.
The symposium is jointly organised by the Department of Chemical Oceanography of Cochin University of Science and Technology (CUSAT), Trevor Platt Science Foundation, CMFRI and the Marine Biological Association of India.
CUSAT Vice-Chancellor Prof M Junaid Bushiri presided over the inaugural function. Prof Shubha Sathyendranath, Principal Scientist at Plymouth Marine Laboratory, UK, Dr Grinson George, Director of CMFRI, Dr N Aparna, Deputy Director of the National Remote Sensing Centre (NRSC) under the Indian Space Research Organisation (ISRO), and Dr Shaju S S, Convenor of the symposium, also spoke.
