The three stations are located in remarkably quiet sites that are close to the sea ice, which is still formed at that time of the year. The absolute gravity measurements at Thiel-1 and SBG-1 stations are the first direct observations, whereas Terra Nova Bay AB Station had already been occupied in 1995 and 1997. From 17 until 28 November 2009, Hut Point Station and Radarsat building at McMurdo Station and ROBE and CRN2 benchmarks at Cape Roberts have been tied to Thiel-1 Station, MMD-N benchmark at Scott Base has been tied to LINZ SBG-1 Station, and the absolute gravity reference station IAGS and relative gravity station IRGS at Mario Zucchelli Station have been tied to Terra Nova Bay AB Station with a Scintrex CG-5 gravimeter.

It originally consisted in making Absolute Gravity (AG) and Relative Gravity (RG) measurements at McMurdo Station (McM), Scott Base (SB), Mario Zucchelli Station (MZS) and Dumont d’Urville (DdU), as well as RG measurements at Cape Roberts (CR). However, because of logistical incompatibilities, the observation at DdU was cancelled. In the following chapters, we successively report on the observations made at McM, SB, CR and MZS. Where available, we compare the observations to measurements previously made at the same location. 1.2 Financial and logistical supports Initiated as a part of project 337 Variation de gravit´eet mouvement vertical dans les r´egions polaires - Apport aux probl`emes du rebond post-glaciaire et de la d´eglaciation actuelle funded by the French Institut Paul-Emile Victor (IPEV) and led by Jacques Hinderer (IPGS), the 2009 AG survey in Antarctica also benefited from the support of the Italian Programma Nazionale di Ricerche in Antartide (PNRA), Land Information New Zealand (LINZ), Antarctica New Zealand (ANZ), and US Antarctic Program (USAP) managed by the National Science Foundation (NSF). It is a part of the international Polar Earth Observing Network (POLENET) project. 1.3 Equipment The AG observations were conducted with the free-fall FG5 #228 gravimeter designed by Micro- g Solutions Inc., owned by the French Institut National des Sciences de l’Univers (INSU), run by G´eosciences Montpellier and operated by Nicolas Le Moigne who was assisted by Rachelle Winefield, Dave Collett, Larry Hothem and Yves Rogister. Observations consisted of sets of 100 drops, one drop every 10 seconds, which were hourly repeated. The AG raw data are corrected for Earth tide, ocean loading, polar motion and atmospheric pressure. The corrections and instrumental parameters are given, for each station, in Appendix E. The RG observations were made with a Scintrex CG-5 gravimeter owned and run by G´eosciences Montpellier. The operators were RW, NLM, LH, DC and YR. 6 Chapter 2 McMurdo Station (US) 2.1 AG at Thiel-1 Station Brief history and description of McMurdo gravity stations can be found in the technical report by Diehl (2008). Thiel gravity station, whose geographical coordinates are given in Table 2.1, was established in Building 146 (Fig. 2.1) in 2000-2001 to replace the SATGRAV station.

No direct AG measurements had been made at Thiel station before November 2009, but the AG had been determined by means of gravity ties (Table 2.2).

OPENING The second planning meeting for the Year of Polar Prediction (YOPP) in the Southern Hemisphere (YOPP-SH) subcommittee was held from 28–29 June 2017 at the National Center for Atmospheric Research in Boulder, Colorado, USA. David Bromwich, member of the Polar Prediction Project Steering Group (PPP-SG), opened this second meeting (YOPP-SH2). He welcomed participants and explained the two key goals of the meeting. One of these was to compile information on the national activities that will contribute to YOPP-SH (during the June 28th afternoon session). Bromwich pointed out the benefits that all nations will have from a joint effort to improve forecasts in the Southern Hemisphere, in particular with regards to logistics needed to carry out research in and around Antarctica.
