A-NET

Led by Ohio State University, A-NET is a GPS/Seismic network spanning West Antarctica. A-NET is unique in that its backbone network consists of both GPS and seismic instrumentation, allowing for a more complete understanding of the interactions between the ice sheets and the underlying bedrock. A-NET is using improved technologies to record measurements year-round and to transmit data from remote sites to archives in the USA.

A-NET Partner Project: GIACAP
GIA Constraints for the Antarctic Peninsula

Eight new GPS receivers will be installed on bedrock in the southern Antarctic Peninsula for improvements in GIA model accuracy and GRACE-based ice mass change estimates. These sites will act as a regional densification of the A-NET project, a major part of the IPY POLENET project.

Participants:
Newcastle Upon Tyne, United Kingdom

A-NET Partner Project: VLNDEF
Victoria Land Network for DEFormation Control

VLNDEF consists of 28 GPS sites on bedrock in northern Victoria Land, led by Dr. Alessandro Capra of University of Modena and Reggio Emilia, Italy and supported by Progetto Nazionale di Ricerca in Antartide (PNRA). VLNDEF includes the continuously-operating GPS station at Mario Zuchelli Station and 4 remote GPS stations operating quasi-continuously.

A-NET Partner Project: LARISSA
LARsen Ice Shelf, Antarctica

LARISSA is a multi-disciplinary NSF-funded study of the LARsen Ice Shelf System, Antarctica, led by Dr. Eugene Domack, Hamilton College, USA. In 2008-9 and 2010-11, 6 new continuous GPS systems will be installed on bedrock by UNAVCO to measure GIA in the region of the former Larsen B embayment as part of LARISSA and the A-NET project of POLENET.
