Project description

The hadal zone is commonly defined as areas deeper than 6,000m and comprises the deepest 45% of the ocean’s depth range, yet accounts for more than 2% of the Earth’s surface.

Globally, 37 trenches and troughs form geographically disjunct deep-sea ecosystems.

These differ from the continuum of the abyssal plain ecosystems due to trench-specific conditions (e.g., depth, isolation and funneling of organic material) and geomorphological characteristics.

My PhD aims to increase our understanding of hadal ecology by focusing on scavenging amphipods.

To this aim, I am characterising the scavenging amphipod community structure across the abyssal-hadal transition zone of the Wallaby-Zenith Fracture Zone, Indian Ocean.

I am using an integrative taxonamic approach to describing new amphipods species.
