Outline of field observations during Observations of surface snow accumulation on the East Antarctic ice sheet have been conducted as part of a monitoring program for assessing the surface mass balance of the ice sheet. Since 1992, 1

2 H. Motoyama et al. Japanese Antarctic Research Expedition (JARE) members have measured surface snow accumulation during traverse surveys between coastal point S16 and the inland Dome Fuji region. Motoyama et al. (2008) reported on the glaciological data collected by the 45th, 46th, and 47th JARE surveys during A new, relatively flat route between Mizuho Station and Relay Point was established during the 51st JARE survey in 2010 (Fig. 1). The observational data collected during by the 48th through 54th JARE surveys are reported here. Snow accumulation data near the coast collected intermittently during these years are also included. Tables 1-1, 1-2, 1-3, and 1-4 summarize the dates of the overland traverses and observations carried out during this period. 2. Net snow accumulation measured by the stake method Net accumulation of snow was measured by the stake method along the traverse routes during (Fig. 1) Route S-H-Z (Mizuho route) Stake heights along the S-H-Z route, between point S16 and the Mizuho Station, were measured 11 times from January 2007 to October The height differences, which approximate the net balance of snow during the observation intervals, are tabulated in Table 2-1. Minimum readings were 1.0 cm. Recent stake positions measured with a handheld global positioning system (GPS) unit are shown in the same table. The coordinate system used was WGS Route MD (Dome Fuji route) Stake heights along the route from Mizuho Station (IM0) to MD738 to point DF80, just beyond Dome Fuji Station, were measured five times from January 2007 to January All data along the route are shown in Table 2-2. Minimum readings were 1.0 cm. Recent stake positions measured with a handheld GPS unit are shown in the same table. The coordinate system used was WGS-84. 2

3 JARE Data Reports, No. 341 (Glaciology 35), November Route NMD (New Mizuho-Relay route) Stake heights along the route from Mizuho Station (IM0) to Relay Point (MD364) were measured three times from December 2009 to December All data along the route are shown in Table 2-3. Minimum readings were 1.0 cm. Recent stake positions measured with a handheld GPS unit are shown in the same table. The coordinate system used was WGS Setup of stake farms and stake rows Stake farms consisting of 36 stakes, separated by 20 m in an orthogonal array covering 100 m 100 m (Fig. 2), were set up at points S16, H68, H180, S122, and Z40 along the Mizuho route and at Dome Fuji Station. Stake heights of these farms were measured several times from 2007 to The results for S16, H68, H180, S122, Z40, and Dome Fuji Station are shown in Tables 2-4, 2-5, 2-6, 2-7, 2-8, and 2-9, respectively. The tables include the averages and standard deviations for the net accumulation of snow during each period. Because some of the stakes were too short, we set up new and longer stakes near the old ones during the survey. A 100-m row consisting of 101 evenly spaced stakes at Mizuho Station was measured 10 times from January 2007 to October The results of the measurements are given in Table The stake numbers are shown in Fig. 3. Again, some of the stakes were too short, so we set up new and longer stakes near the old ones during the survey. Four 100-m rows consisting of 50 evenly spaced stakes at points MD180, MD364, MD560, and DF80 were measured five times from January 2007 to January These stake rows are perpendicular to the prevailing wind direction (Fig. 4). The results are shown in Tables 2-11, 2-12, 2-13, and Recent stake positions measured with a handheld GPS unit are shown in Table The coordinate system used was WGS Snow accumulation near the coast Stake heights along the route near the coast between Tottsuki and S16 were measured several times a year. However, snow accumulation data were few in this region because the snow stakes were 3

4 H. Motoyama et al. damaged by strong winds, glacier flow, and surface ice melt. The height differences, which approximate the net balance of snow during the observation intervals, are tabulated in Table 3. Minimum readings were 1.0 cm. Recent stake positions measured with a handheld GPS unit are shown in the same table. The coordinate system used was WGS Digital data archive All digital data will be archived and available from the online Science Database of the National Institute of Polar Research ( Inquiries about details of the data records should be addressed to the following scientist: Hideaki Motoyama National Institute of Polar Research motoyama@nipr.ac.jp Acknowledgments We express our sincere thanks to all members of JAREs 48, 49, 50, 51, 52, 53, and 54, who extended generous and long-term support.
