Dr Jan Jansen is a Postdoctoral Research Fellow at the Institute for Marine and Antarctic Studies. He investigates how physical and biological factors influence the distribution of marine biodiversity, how marine biodiversity changes through time, and how new research tools can be used to study these relationships more precisely and effectively. His research primarily focusses on diverse seafloor communities in the deep waters around the Antarctic and Australia. Research tools include statistical models, qualitative network models and deep-learning algorithms.
Jan completed his PhD in Quantitative Antarctic Studies at UTAS in 2019 investigating spatial, temporal and structural patterns in the distribution of Antarctic seafloor biodiversity.
Before starting his current position as a Postdoctoral Research Fellow at UTAS in March 2019, he has held various casual positions at UTAS focussing on field-work and teaching, and a short temporary full-time position as a quantitative ecologist at UTAS mapping the distribution of biodiversity on the seamounts of South Tasmania and creating an ecoregionalisation of the deep Great Australian Bight.

Jan’s research aligns largely to the University’s research themes of Marine, Antarctic and Maritime. His research interests focus on better understanding how the diversity of marine life is distributed, using a wide range of multidisciplinary approaches. His research focusses in particular on the distribution of Antarctic seafloor biodiversity, where he is leading a large international collaboration to map the distribution of biodiversity on the entire Antarctic continental shelf. The biodiversity of the Antarctic seafloor has never been mapped before because only very little data are available and because the tools to do so were missing. However, Jan’s previous work has helped to now make this achievable and the maps once produced will have a major impact on our ecological understanding of the continent and on how decisions to manage and conserve Antarctica can be made.
Dr Jansen is currently involved in a large international collaboration to map the distribution of seafloor biodiversity on the Antarctic continental shelf. He has established and fostered collaborations with researchers from CSIRO, Geoscience Australia, the Australian Antarctic Division, the Alfred-Wegener Institute in Bremerhaven (GER), the British Antarctic Survey in Cambridge (UK), the Sorbonne University in Paris (FR), the Muséum national d'Histoire naturelle in Paris (FR) and the National Institute of Water and Atmospheric Research (NIWA) in Wellington (NZ).

Machine-learning assisted annotation of seafloor images:
In collaboration with computer scientists from the University of Tasmania, Dr Jansen is developing deep-learning models to assist the detection and classification of animals in seafloor images. This research aims to speed up annotation and reduce human errors in analysis, critical for addressing the current bottleneck that exist in translating raw seafloor images into biodiversity data for management and conservation.
Predicting biodiversity distribution on the Antarctic continental shelf:
Antarctic seafloor communities are unique and highly diverse, but their distribution is poorly known because biological data are sparse. This project aims to develop an international database of underwater observations to, for the first time, predict the distribution of seafloor biodiversity over the entire Antarctic continental shelf for the present day and 2100. These predictions depend on a unique and validated approach to estimate the present and future distribution of surface primary production to the seafloor, and will enable calculating the amount of atmospheric carbon captured and stored at the seafloor. The maps will be at an unprecedented resolution (~2 km), and be invaluable tools underpinning policy, management and future science.

Dr Jansen has written several papers, some of which have received attention in the popular media and on social platforms. Altmetric scores for three of his papers are in the top 5% of all research outputs tracked, reflecting the high public attention these papers have received. In particular, Dr Jansen’s research has received worldwide attention in the news for his paper in Nature Ecology & Evolution (Jansen et al. 2018), with articles published in English, Chinese, Spanish, Swedish, Indonesian and Australian news-outlets. Videos explaining the research and showing footage of the Antarctic seafloor were widely shared and viewed close to a million times on social media, with contributions from National Geographic, the Australian Academy of Science and Australia’s Science Channel.
