In May of 2012 we completed a month-long cruise of the Line Islands region aboard the R/V Marcus G. Langseth. The Line Islands are a relatively shallow chain of atolls created by hot spot volcanism and were targeted for sediment coring because the bathymetry indicated that the preservation potential for calcareous sediments might be high. Climatically, the area is situated beneath the seasonally shifting ITCZ and is influenced by ENSO making it an ideal area for paleoclimatic reconstructions aimed at evaluating shifts and changes in these two ocean-atmosphere phenomena. We recovered 41 sediment cores from the area, including three which are currently the focus of my doctoral research (ML1208-37BB, 31BB and 17PC). The cores are archived at the Lamont-Doherty Earth Observatory Core Repository
