Spatial patterns and key drivers of zooplankton in the north central Indian Ocean
Zooplankton is a vital component in the pelagic marine ecosystems, linking lower to higher trophic levels. A survey was conducted with R/V Dr. Fridtjof Nansen in Sri Lankan waters in summer 2018 to explore zooplankton dynamics in relation to abiotic and biotic variables. A distinct pattern in physic...

Zooplankton is a vital component in the pelagic marine ecosystems, linking lower to higher trophic levels.
