Biological Characterization of the Mediolittoral and Infralittoral Zones of the West Coast of Anticosti Island (2021-2024) | Caractérisation biologique des zones médiolittorale et infralittorale de la côte ouest de l'Île d'Anticosti (2021-2024)

This dataset includes measurements of abundance, density, biomass and length of macroalgae from the Algae-WISE project and data on landscape description, macroalgae cover and biomass as well as the abundance and length of benthic macrofauna from the project for the optical and biophysical characterization of the mediolittoral and infralittoral zones of the southwest coast of Anticosti Island. The objective of the Algae-Wise project is to demonstrate the potential of hyperspectral and multispectral imaging for the detection and quantification of three types of marine algal biomass, which are the basis for the productivity and vitality of the ecosystem: phytoplankton, fixed macroalgae and drifting macroalgae. The objective of the optical and biophysical characterization of the mediolittoral and infralittoral areas of the southwest coast of Anticosti Island is to characterize and map shallow coastal ecosystems in order to offer a description of a reference state. In the context of the Algae-WISE project, intensive field campaigns were carried out on the southwest coast of Anticosti Island during the summer period (between June and September) in the summers of 2021, 2022 and 2023. As part of the characterization project, an intensive campaign in July 2024 was carried out on the southwest coast of Anticosti Island.
