| Summary: | Initiatives to study the impact of climate change on carbon sequestration in the subantarctic Southern Ocean have led to regular research voyages and the establishment of long-term moorings at the Southern Ocean Time Series site (47oS, 140oE) in the region. The subantarctic zone plays an important role in the physical uptake and sequestration of carbon dioxide due to the formation and subduction of water masses. However, while extensively studied in other parts of the world's ocean, the biological production, transformation, and transport of particulate material is not well documented for the subantarctic zone. In particular, the role of zooplankton in the biological gravitational, mesopelagic-migrant, and seasonal lipid pumps has received less attention. Current knowledge gaps extend across zooplankton species composition in subsurface waters and its seasonal development, zooplankton mortality that leads to downward carbon ux by carcasses and quanti _cation of zooplankton respiration in the water column. ... |
