Integrating Biodiversity Science with Remote Sensing: The BioSCape (SAEON Seminar, March 2024)

Dr Anabelle Cardoso (University at Buffalo & University of Cape Town) Title: Integrating Biodiversity Science with Remote Sensing: The Biodiversity Survey of the Cape (BioSCape) Abstract: This seminar will give an overview of the BioSCape project, including an introduction to its expected datasets. BioSCape is NASA's first biodiversity-focused integrated airborne field campaign. It took place in South Africa in Oct-Nov 2023 and investigates the structure, function, and composition of ecosystems, and how and why they are changing in time and space. BioSCape's airborne dataset is unprecedented in its instrument combination and level of detail, with near complete coverage of the electromagnetic spectrum at high resolution and coincident full-waveform lidar acquisitions. BioSCape's field datasets quantify the diversity of plant communities including alien invasives and kelp, phytoplankton functional types, phylogenetic histories, eDNA in watersheds, bird and frog acoustics, plant functional and spectral traits, blue carbon, and in-water radiometry. BioSCape is committed to facilitating Open Science and all datasets will be delivered to one of NASA's Distributed Archive and Analysis Centers. South Africa is ideally placed in the crossroads of three ocean basins and three massive and distinct ocean boundary currents. Observations need to be made in such a way that they complement modelling studies and operational activities, such as global weather forecast models, provide insights to unique ocean processes and are able, to some degree, provide the information needed to mitigate against extreme weather and ocean phenomena. So where should we deploy ocean observing infrastructure to provide the best bang for our buck? In this presentation we explore the possibilities within the boundary currents around South Africa, look at existing initiatives undertaken by various South African teams, and try to work out where the gaps are.
