Figure F34. Catwalk temperature and light intensity recorded during Expedition 311. Measurements were made 2.35 m from the core 0 point (end of catwalk closest to rig floor). Diurnal temperature changes that were characteristic of the early days of the expedition, when days were bright and sunny, were muted during the latter part of the expedition. Note the large, abrupt change in temperature that occurred during coring at Site U1326. Times (open symbols) of collecting individual cores are shown at the top of the figure for all sites. Each symbol corresponds to a single core. GMT = Greenwich Mean Time.
