Why in news: INCOIS scientists identified marine heatwaves and coastal upwelling as primary drivers behind unusual sardine strandings along India's west coast.
The Indian National Centre for Ocean Information Services (INCOIS) identified a complex interplay of factors including marine heatwaves, coastal upwelling, ocean currents, tidal forcing, and extreme weather events. These disruptions are impacting the marine ecosystem and affecting local fishing communities.
