Tina Brenneis

Tina Brenneis is a Researcher at the Alfred Wegener Institute, contributing to marine biogeochemistry and phytoplankton ecology. She focuses on the impacts of ocean acidification, iron availability, and environmental stressors on Southern Ocean and Arctic phytoplankton communities. Her work bridges laboratory studies and field observations to understand ecosystem responses to climate change.

Her research spans topics like phytoplankton physiology, trace metal dynamics, and carbon cycling, with a focus on species such as Phaeocystis antarctica, diatoms, and coccolithophores. Recent studies include investigations into omega-3 fatty acid depletion in Arctic marine algae and the effects of dissolved domoic acid on iron-stressed phytoplankton.

Brenneis collaborates internationally on projects addressing climate change impacts in polar regions. Her publications highlight interdisciplinary approaches to understanding marine ecosystem resilience under environmental shifts.
