US AMLR Program zooplankton dataset

Metadata Updated: March 1, 2024

Zooplankton research in the US AMLR Program focuses on the link between prey production, availability, and climate variability in relation to predator and fishery demands. Annual studies include estimates of krill abundance, and experiments to develop and enhance hydro-acoustic methodologies. Long-term objectives include quantifying the inter-annual and decadal mesoscale (10's to 100's of kilometers) variability in water mass structure, phytoplankton biomass and productivity, and zooplankton (especially krill) associated with potential basin scale climate forcing. Conversely, the microscale (1 to 10's of kilometers) features of the distribution and abundance of krill within the foraging range of krill predators breeding at Cape Shirreff and Admiralty Bay is also studied to resolve local and remote forcing effects on predator foraging success.
