Autor: Natasha Henschke, Boris Espinasse, Charles A. Stock, Xiao Liu, Nicolas Barrier, Evgeny A. Pakhomov
Publikováno v: Scientific Reports, Vol 13, Iss 1, Pp 1-8 (2023)
Abstract Salpa thompsoni is an important grazer in the Southern Ocean. Their abundance in the western Antarctic Peninsula is highly variable, varying by up to 5000-fold inter-annually. Here, we use a particle-tracking model to simulate the potential

In the Southern Ocean, several zooplankton taxonomic groups, euphausiids, copepods, salps and pteropods, are notable because of their biomass and abundance and their roles in maintaining food webs and ecosystem structure and function, including the p

Mesozooplankton and Micronekton Active Carbon Transport in Contrasting Eddies
Autor: Lian E. Kwong, Natasha Henschke, Evgeny A. Pakhomov, Jason D. Everett, Iain M. Suthers
Publikováno v: Frontiers in Marine Science, Vol 6 (2020)
Mesozooplankton (June 2015 and September 2017) and micronekton (September 2017) were sampled along the eastern coast of Australia. Depth stratified mesozooplankton and micronekton were collected using a Multiple Opening/Closing Net and Environmental

Global ecological and biogeochemical impacts of pelagic tunicates
Autor: Jessica Y. Luo, Charles A. Stock, Natasha Henschke, John P. Dunne, Todd D. O’Brien
The pelagic tunicates, gelatinous zooplankton that include salps, doliolids, and appendicularians, are filter feeding grazers thought to produce a significant amount of particulate organic carbon (POC) detritus. However, traditional sampling methods

Large Vertical Migrations of Pyrosoma atlanticum Play an Important Role in Active Carbon Transport
Autor: Jason D. Everett, Amy R. Coghlan, Natasha Henschke, Iain M. Suthers, Evgeny A. Pakhomov, Leonardo Laiolo, Lian E. Kwong
Publikováno v: Journal of Geophysical Research: Biogeosciences. 124:1056-1070
Pyrosomes are efficient grazers that can form dense aggregations. Their clearance rates are among the highest of any zooplankton grazer, and they can rapidly repackage what they consume into thousands of fecal pellets per hour. In recent years, pyros

The Southern Ocean near the Western Antarctic Peninsula (WAP) is strongly affected by climate change resulting in warmer air temperature, accompanied with reduced sea ice coverage, increased sea water temperature and potential changes in the abundanc
