Description

This project investigates the evolution, genome structure, and associated biomes of foraminiferan protists (forams) belonging to three distinct, early-evolving clades: notodendrodids, crithioninids, and astramminids. Researchers will dive under the sea ice at Explorers Cove, Cape Bernacchi, and McMurdo Station to collect forams and sediment cores. They will use next-generation sequencing (NGS) and simple microdissection methods to obtain and analyze nuclear and mitochondrial genomes of the forams. In an effort to better understand factors involved in both the large-scale and micro-scale distribution of forams, researchers will also use NGS to characterize the in-situ prokaryotic assemblages of notodendrodids and compare them to reference sediment microbiomes.


Field Season Overview

A team of six will travel by helicopter to New Harbor where they will stay at an established camp to conduct their dives. From there, they will make day trips by ATV and snowmobile to additional sea-ice dive sites. The divers plan to conduct an estimated 40 dive missions to collect forams and sediment cores.
