Sub-Milankovich millennial cycles in proxy (UK37) sea surface temperatures for the Okinawa trough, W Mediterranean Sea, NW Atlantic Ocean and Southern Ocean

Sea surface paleo-temperatures for the Holocene deduced using the UK37 proxy are studied for four sites; the Okinawa trough (IODP hole 1202B); western Mediterranean Sea (Core 293G); NW Atlantic ocean (off-shore Portugal Core MD95-2042); Southern Ocean (off-shore S Australia, Murray Canyon, core MD03-2607). Data lengths are to 100-20K, 100-20K, 100-70K and 1100-134K years BP respectively. The sampling in time provided by the four data sets differs by an order of magnitude, ranging from the very high sedimentation rate in the Okinawa trough (84m of core over 20K years, time samples range from 20 yr to 100yr over the core length) tomodest rate of the Murray Canyon (2.4 m core over 20K yr or 15 m over 134K yr, time sampling 300 yr).
