Larissa Macedo


Larissa obtained her Bachelor in Geology from Universidade Federal de Sergipe, Brazil in 2019 and a technical degree in Information Technology from Instituto Federal de Sergipe in 2018. She has worked as an undergraduate researcher in Palaeontology of Cretaceous marine environments, Coastal Sedimentology and Hydrogeology. In 2019, Larissa joined the Marine Geology Research Group project as an MSc by Research student in the MMMonKey_Pro project with the research “Advancing seabed mapping techniques for deep-water habitat classification in Submarine Canyons” (ASMaT). In 2020, Larissa obtained a scholarship award from the Government of Ireland Postgraduate Scholarship to further develop her current research as a PhD in UCC. She is working under the supervision of Dr Aaron Lim, Professor Andy Wheeler and Professor Luis Conti (Brazil).

Larissa’s project focuses on advancing seabed mapping techniques for deep-water habitat classification in Submarine Canyons. She is currently working on the application of novel and existing multiscale mapping methods for 3D images to further understand CWC features in the Porcupine Bank Canyon (PBC), NE Atlantic. The key aims of Larissa`s research are to develop a 3D imaging classification workflow for deep-water habits as well as determining the appropriate mapping scale for different research objectives in Cold Water Coral habitats. For that, Larissa utilises a set of 3D models reconstructed from ROV’s high-resolution video recording with Structure-from-Motion (SfM) and combines different image processing techniques into frameworks to analyse 2D and 3D data deliverables and losses.
