Title: Untangling the causes of change over 25 years in the southeast marine ecosystem - Voyage IV
Period: 2025-05-26 22:30 to 2025-06-27 22:00 UTC
Duration: 31.98 days
From: Hobart To: Hobart
Ship: Investigator (RV) [details]
Description: Our sampling protocol is driven by the effects that we have hypothesised to explain apparent trends in fish abundance. These impacts include changes that have occurred to the benthic habitat (H1: habitat modification hypothesis), changing food webs (H2: habitat hypothesis); water column (H3: climate hypothesis), and fishery catch. They are not independent of each other and can operate either directly on the species or indirectly through the supporting habitats and associated trophic systems.
