The marine waters of SE Australia are in a global warming hotspot where the East Australian Current is extending pole-wards, warming the ocean at more than four times the global average. Anecdotal evidence from the Southern and Eastern Scalefish and Shark Fishery (SESSF) that operates in the region indicates that the ecosystem has changed but the reasons are unclear. The South-East Australian Marine Ecosystem Survey (SEA-MES) is revisiting a survey conducted 30 years ago to understand what is driving the changes being seen and why, with a focus on climate change, and bottom contact fishing (trawling).
SEA-MES is a comprehensive multi-year biophysical research project on RV Investigator, Australia's multi-purpose oceanographic research vessel. Sampling methods consist of demersal and mid-water trawl, deep-towed video, and physical analysis of the water column. Prospective technologies are also being tested.
The ecosystem is a busy and valuable place, containing industries such as oil and gas, shipping and a developing offshore wind sector. It also holds important cultural heritage in the Australian Southeast Marine Park Network, and proposed indigenous Sea Country such as the tayaritja Sea Country IPA. Understanding the pressures on it, what has changed and why, is important for protecting environmental and cultural heritage.
