This project will examine the effects of environmental change on a key Antarctic marine invertebrate — a pelagic mollusk, the pteropod, Limacina helicina antarctica. There are two main activities in this project: (1) To deploy oceanographic equipment — in this case, autonomously recording pH sensors called SeaFETs (sea field-effect transistors) and other devices that record temperature and salinity; and (2) To use these environmental data in the laboratory at McMurdo Station to study the response of the marine invertebrates to future changes in water quality that are expected in the next few decades. The researcher's objective this season is to retrieve three SeaFET sensors in early Mainbody from Cape Evans, the Jetty, and New Harbor.
Field Season Overview:
Our field requirements will be minimal this season: we are only sending one person to deal with the sensors. This individual will need to work with the divers and accompany them onto the sea ice in order to facilitate the sensor swap. We will need some access to bench space so that the sensors can be assembled and tested. The preparation process also requires that we submerge them in water for a few days before deployment so access to a seawater table to a tank will be needed.
