The AUStralian Tidal Energy (AUSTEn) project was a three year project (2018 - 2020) funded by the Australian Renewable Energy National Agency (agreement number G00902) led by the Australian Maritime College (University of Tasmania), in partnership with CSIRO and University of Queensland. The project had a strong industry support (Atlantis Resources Limited, MAKO Tidal Turbines Ltd, Spiral Energy Corporation Ltd). The aim of the project was to assess the technical and economic feasibility of tidal energy in Australia, based on the best understanding of resource achievable.

This record provides an overview of the scope and research output of NESP Marine Biodiversity Hub project E7 - "Assessing the feasibility of restoring giant kelp beds in eastern Tasmania". For specific data outputs from this project, please see child records associated with this metadata. -------------------- This project will extend an externally funded project conducted through UTAS commencing in 2018 to select for thermally tolerant and low-nutrient-tolerant giant kelp (Macrocystis pyrifera) genotypes, and to examine effects of acclimation of selected genotypes by pre-exposure to warm, nutrient-poor conditions. The proposed project will outplant pre-exposed selected genotypes of giant kelp as micro-sporophytes in an experiment with and without provision of an added source of nutrient. The work is designed to assess the feasibility of this approach as a means to develop minimum patch sizes for giant kelp that can be self-replacing and self-expanding, thus providing restoration and future climate-proofing options for this EPBC-listed marine community. Planned Outputs • Experimental data from macrocystis restoration • Final report

This record provides an overview of the scope and research output of NESP Marine Biodiversity Hub Project D6 - "Socioeconomic benchmarks". For specific data outputs from this project, please see child records associated with this metadata. -------------------- Social and economic values are key drivers for marine science and marine policy but are too rarely integrated with marine biodiversity monitoring programs. In close consultation with Parks Australia (PA) we will review existing metrics used to survey social and economic values associated with marine parks. This review will include consulting with national and international expertise and actively consulting with State and other Commonwealth agencies, some of whom are currently conducting reviews or have existing frameworks for surveying social and economic values (e.g Great Barrier Reef Marine Park Authority (GBRMPA), NSW Department of Primary Industries (DPI)). In collaboration with national partners and PA we will organise a national methods workshops to discuss and refine metrics and methods to quantify social and economic benchmarks for State and Australian Marine Parks (AMPs) and produce Standard Operating Procedure’s (SOP) relevant to AMPs taking into consideration the Department of the Environment and Energy’s (DoEE’s) environmental accounting processes and PA’s Monitoring, Evaluation, Reporting and Improvement (MERI) framework. Planned Outputs • SOP for measuring social and economic metrics for AMPs • Final report on essential (key) AMP social and economic metrics • Summaries of research and surveys made available through the Marine Parks Science Atlas

Antarctic krill (Euphausia superba) have a keystone role in the Southern Ocean, as the primary prey of Antarctic predators. Any decreases in krill abundance could result in a major ecological regime shift, but there is currently limited information on how climate change may affect krill. Increasing anthropogenic carbon dioxide (CO2) emissions are causing ocean acidification, as absorption of atmospheric CO2 in seawater alters ocean chemistry. Ocean acidification increases mortality and negatively affects physiological functioning in some marine invertebrates, and is predicted to occur most rapidly at high latitudes. Here we show that, in the laboratory, adult krill are able to survive, grow, store fat, mature, and maintain respiration rates when exposed to near-future ocean acidification (1000 – 2000 μatm pCO2) for one year. Despite differences in seawater pCO2 incubation conditions, adult krill are able to actively maintain the acid-base balance of their body fluids in near-future pCO2, which enhances their resilience to ocean acidification.

This record provides an overview of the scope and research output of NESP Marine Biodiversity Hub Project D5 - "A standardised national assessment of the state of coral and rocky reef biodiversity". For specific data outputs from this project, please see child records associated with this metadata. -------------------- This project will involve integration of a national suite of reef biota Underwater Visual Census (UVC) monitoring datasets (Reef Life Survey (RLS), University of Tasmania (UTAS), Australian Institute for Marine Science (AIMS), Parks Victoria (PV), SA Department of environment, water and natural resources (DEWNR)) to provide a comprehensive update to the state of Australian Reefs report for the next national State of the Environment Report. Maps and indicator trends will show changes in the health of rocky and coral reefs nationally from 2005 to 2020. The update will include addition of a new index which summarises the population trajectories for 600-1000 reef species nationally. Individual species trajectories will provide the only threat status information for the majority of these species, assisting future listing of previously unassessed species if significant declines are detected. Planned Outputs • Maps and trends in SoE indicators • Raw data underlying SoE analyses (data use agreement must be signed with AIMS for access to that data) • Various scientific papers
