. Atoll research bulletin. Coral reefs and islands; Marine biology; Marine sciences. METHODS Field Work A total of 19 vibracores were collected along north/south and east/west transects across Twin Cays (Fig. 1). The first 6 cores were collected by a team led by Lighty in 1984. In the following year, Macintyre's group collected an additional 13 cores. Continuous sediment and peat sections were vibracored using 9 m-long, cm-diameter aluminum core tubes, each fitted with a core catcher (Fig. 2). Offshore work was relatively easy compared with the movement of this heavy equipment in
