The overall objective of NECCTON is to enable Copernicus Marine Service to deliver products that inform marine biodiversity conservation and food resources management, by fusing ocean ecosystem models and data. This report provides a description of five data products that will be developed by NECCTON for trophic levels above zooplankton, broadly referred to as higher trophic levels (HTL) as future potential new products for Copernicus Marine Service: small pelagics biomass, large pelagics, demersal fish biomass, unspecified fish biomass, and marine mammals habitat (a proxy for potential species distributions).
