Anderson et al. 2002 Faunal Abundance data from Arabian Sea Box Cores. Composite of Cores RC2730 and RC2735 Core RC2735 (18° 14'N, 57° 36'E, water depth 498 m, core length 42 cm) Core RC2730 (18° 13'N, 57°41' E, water depth 698 m, core length 51 cm) age_for_averages is the year AD mid-point of the 50 year age bin used to average all bulloides data 50_year average is the average G. bulloides percentage based on averaging all data points within a 50 year window avg-sqrt is the square root of the differences in G. bulloides percentage from the 1975 average (34 age is the year A.D. For the sediment sample g.bull is the percentage of G. bulloides relative to other planktonic foraminifers age_for_averages 50_year_avg avg-sqrt age g.bull core 1975 33.5 0.0 1986 34 rc2735 1925 28.4 2.2 1986 38 rc2730 1875 26.3 2.6 1973 29 rc2735 1825 16.8 4.0 1967 34 rc2730 1775 23.2 3.1 1960 32 rc2735 1725 23.2 3.1 1948 27 rc2730 1675 16.9 4.0 1947 27 rc2735 1625 10.2 4.8 1934 32 rc2735 1575 10.8 4.7 1929 24 rc2730 1525 13.9 4.4 1921 32 rc2735 1475 13.2 4.5 1910 25 rc2730 1425 15.0 4.2 1908 31 rc2735 1375 14.7 4.3 1895 29 rc2735 1325 17.1 4.0 1891 26 rc2730 1275 18.7 3.8 1882 28 rc2735 1225 17.9 3.9 1872 28 rc2730 1175 19.0 3.7 1856 31 rc2735 1125 13.3 4.4 1853 17 rc2730 1075 14.0 4.4 1842 23 rc2735 1834 15 rc2730 1829 29 rc2735 1816 24 rc2735 1815 21 rc2730 1803 25 rc2735 1796 18 rc2730 1790 27 rc2735 1777 28 rc2735 1776 15 rc2730 1764 26 rc2735 1757 25 rc2730 1751 24 rc2735 1738 26 rc2735 1725 20 rc2735 1719 23 rc2730 1712 24 rc2735 1700 15 rc2730 1699 23 rc2735 1686 20 rc2735 1681 15 rc2730 1662 10 rc2730 1660 18 rc2735 1643 7 rc2730 1634 14 rc2735 1624 8 rc2730 1610 14 rc2735 1605 8 rc2730 1587 13 rc2735 1586 10 rc2730 1567 9 rc2730 1564 12 rc2735 1548 17 rc2730 1540 14 rc2735 1529 12 rc2730 1517 14 rc2735 1510 13 rc2730 1494 15 rc2735 1491 10 rc2730 1472 9 rc2730 1470 23 rc2735 1453 9 rc2730 1447 21 rc2735 1434 8 rc2730 1424 19 rc2735 1415 12 rc2730 1400 15 rc2735 1396 8 rc2730 1377 22 rc2735 1376 16 rc2730 1357 12 rc2730 1354 20 rc2735 1338 14 rc2730 1330 22 rc2735 1319 13 rc2730 1307 20 rc2735 1300 17 rc2730 1284 18 rc2735 1281 15 rc2730 1262 14 rc2730 1260 28 rc2735 1243 12 rc2730 1237 29 rc2735 1224 11 rc2730 1214 22 rc2735 1205 15 rc2730 1190 25 rc2735 1186 14 rc2730 1167 11 rc2730 1167 27 rc2735 1148 12 rc2730 1144 16 rc2735 1129 8 rc2730 1120 21 rc2735 1110 10 rc2730 1097 17 rc2735 1091 9 rc2730 1072 16 rc2730 1053 14 rc2730
