Adaptive responses of Phaeocystis populations in Antarctic ecosystems

Program Manager:
Dr. Charles Amsler

Event Number: B-244-N

ASC POC/Implementer:
Adam Jenkins

Dr. Kevin Arrigo (Principal Investigator)

Stanford University
Stanford, California

Supporting Stations:  RV/IB Nathaniel B. Palmer
Research Locations:  Ross Sea

Project Description:
Researcher's objectives are to use a combination of field and laboratory-based studies to identify the environmental factors that control the distribution of the unicellular algae, Phaeocystis antarctica, in the Southern Ocean and to identify the specific adaptive responses to these environmental factors.

Field Season Overview:
Field team members will sail on the R/V Nathaniel B. Palmer from Punta Arenas, Chile to collect water samples from the Ross Sea Polynya. While underway, they will sample open ocean waters of the Antarctic Circumpolar Current. Researchers will also conduct shipboard sampling and incubations in deck incubators under trace metal clean conditions to assess the factors that control the growth of Phaeocystis antarctica in different locations. They will take samples from the water column and conduct incubations for both physiological properties as well as genomic characteristics and diversity.

Deploying Team Members:
