My research revolves around improving our understanding of modern and ancient phytoplankton and their relationships with the environment - now, in the past and in the future. I maintain a broad, interdisciplinary background in marine science, biological oceanography, micropaleontology and marine and paleo-genomics. I am particularly passionate about ship work at high latitudes and exploring marine sediment records to investigate phytoplankton-environment relationships over geological timescales.
Currently, I am working with ancient phytoplankton DNA from sediment cores taken along the coast of Australia. Genetic community data from these samples will be correlated with the timing and distribution of harmful algal blooms, and the spread of invasive microalgal species, along the East Australian coastline.
Recently, I have also been part of IODP Exp. 382 'Iceberg Alley and Subantarctic Ice and Ocean Dynamics' on board the RV Joides Resolution between March and May 2019 (https://joidesresolution.org/expedition/382/). My personal expedition blog can be found here: https://lindaarmbrecht.home.blog/. An overview about my research on marine sedimentary ancient DNA can be found in this short video, produced by Lee Stevens/IODP: https://www.youtube.com/watch?v=j23I1Quv0nM

Marine phytoplankton are globally important microorganisms that live in the ocean’s surface. When these tiny organisms die, they sink to the seafloor and over time build up complex layers in the ocean sediments. By extracting ancient DNA from such sediments, past phytoplankton communities can be reconstructed, providing information on past environmental conditions and climate. This novel knowledge about past marine community adaptation to previous regional and global warming periods helps inform predictions of future marine ecosystem resilience guiding management efforts of marine ecosystems during present-day climate change.
Study opportunities on all levels (Internships, Honours, Masters, PhD) are available with regard to the reconstruction of Antarctic phytoplankton communities and their responses to variations in climate. Sediment cores used for this research were collected off East and West Antarctica, and are dated to the Last Glacial Maximum (~20-25 kyr). This research is highly interdisciplinary, spanning across marine science, biological/palae-oceanography, and palaeo-genomics, and a good understanding in at least one of these disciplines is required. Study activities include, for example, marine field-work (topic-dependent), laboratory tasks, bioinformatics and data analysis.
