Ocean inundation is exacerbating erosion at Seal Rocks in Victoria, Australia and affecting breeding areas of Australian fur seals. Projections of 60cm increase in storm inundation by 2100 are being surpassed and storm frequency is increasing.
From design to implementation, ‘Lost at Sea’ is a partnership between Phillip Island Nature Parks, Monash University, Bunurong Land Council Aboriginal Corporation (BLCAC) and ecotourism provider Wildlife Coast Cruises. BLCAC, the Traditional Custodians of the region, identify a significant and deep connection to this landscape that is multi-faceted and interconnected and an urgent Cultural Values Assessment was performed in 2024 to capture critical information.
Pup mortality may exceed 35% of pup production, with inundation increasing the risk of drowning and cold exposure for young pups. Modelling using LiDAR drone surveys and in-situ wave loggers confirm the inundation extent and causes of erosion, while temperature loggers confirm extreme temperature ranges experienced by the fur seals.
This research has contributed to the protection of tangible and intangible Bunurong cultural heritage associated with Seal Rocks and Wunmarrinh (Western Port Bay). The research will also communicate impacts of climate change for a broad audience and identify potential refuge areas for the fur seals should they become climate refugees.
