Director's message

Welcome to the latest edition of the Marine National Facility (MNF) newsletter.

It’s been a big few months for the MNF and we’ve enjoyed plenty of opportunities to engage the wider community on a range of topics. 

In July, we called on the research community to provide input into our MNF Capability Needs Survey to help guide our future investment in capability enhancements and upgrades to research vessel (RV) Investigator. We were extremely pleased to receive more than 20 submissions from members of the research community and we thank everyone who took the time to make a submission in this first call. The information gathered is now helping inform the development of our MNF 5-Year Strategic Capital Expenditure Plan which will be designed to ensure we continue to support national priority research needs now and into the future.

Please note that capability proposals can still be made at any time and submissions will continue to be compiled at regular intervals for review by the MNF Technical and Innovation Advisory Group (TIAG).

In July, we had the pleasure of connecting with the research community at the Australian Marine Sciences Association Conference in Melbourne. This was another great opportunity to share information about upcoming MNF voyages and projects and to gather feedback from researchers on ways the MNF can support their work.

Last month we opened up RV Investigator to the public in Hobart, welcoming hundreds of people - and the team from the ABC Radio Hobart's Afternoons Program - on board to visit the vessel for our Ship Open Day. Thank you to everyone who came to visit Australia’s amazing science ship – we loved having you!

Now I’m going to ask our research community to do something to help support the MNF. When research infrastructure funding is being shared across more and more valuable facilities, it is clear to me just how important it is to have our researchers and collaborators - who use and benefit from our data and RV Investigator sea time in advancing their research - to acknowledge the MNF in research papers, media and other publications. Aside from being a requirement for using our scientific services, this acknowledgement is extremely important as it demonstrates to the wider public the value and impact of the MNF.

These acknowledgements will become increasingly powerful in assisting us when we are seeking future funding for the MNF so we thank you, in advance, for your support in this. 

Please reach out to the MNF team if you have a research paper coming up. We are always keen to promote the impact of our collective collaboration and highlight your work across our channels. 

For now, have a happy and safe few months and I wish all those heading to sea on RV Investigator safe and successful voyages.

Toni Moate
MNF Director

Investigating the 2022 eruption of Tonga's Hunga Volcano

Research vessel (RV) Investigator is currently on a 54-day voyage to Tonga to investigate the eruption, destruction and seafloor ecosystem recovery following the 2022 eruption of the underwater Hunga Volcano. Led by the University of Tasmania, a collaborative international science team will conduct more than 120 scientific operations in and around the volcano to gather vital data about the eruption and, importantly, how seafloor communities are recovering.

The 2022 eruption severely impacted Tonga's people and the knowledge generated from this voyage seeks to assist the continuing recovery of communities and help in planning to reduce the future risk from volcanic hazards.

Research on the radar

Welcome to our newsletter feature where we highlight recent publications from research delivered using MNF infrastructure and data.

Discovery of the William's Ridge and Rig Seismic Seamount Microcontinents, Kerguelen Plateau: Signatures of a Fragmented Rifted Margin
Jeremy L. Asimus, Jacqueline A. Halpin, Nathan R. Daczko, Joanne M. Whittaker, Millard F. Coffin, Ivan Belousov, Jacob A. Mulder, and Stijn Glorie| June 2025

Oceanic large igneous provinces are vast accumulations of mafic igneous rock in ocean basins formed by plate tectonic and mantle processes. While these features are mostly composed of igneous rocks, embedded fragments of continental crust are becoming increasingly recognized. Several such continental fragments have been identified in the subantarctic Kerguelen Plateau. Here, we examine the geology of William's Ridge and Rig Seismic Seamount, two previously understudied regions of the Kerguelen Plateau, using rock samples dredged during the RV Investigator voyage IN2020_V01.

Antarctic Krill with parasites grow slower than uninfected peers
A. C. Cleary, S. Kawaguchi, R. King, J. E. Melvin, and G. A. Tarling | June 2025

Antarctic krill, Euphausia superba, are both central ecosystem components in the Southern Ocean, and the target of a growing commercial fishery. Understanding the trophic interactions which shape krill population dynamics is essential to sustainably managing human impacts on this key species. While the roles of krill as grazers of phytoplankton and as prey for vertebrate predators are relatively well understood, very little is known about interactions with their smallest predators – the parasites. We investigated the assemblage of parasites present in E. superba, and the impacts of parasites on krill somatic growth.
