Why in news
INCOIS scientists identified marine heatwaves and coastal upwelling as primary drivers behind unusual sardine strandings along India's west coast.
Background
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.
