Presentation Transcript

  1. GRADES-QWAD • – marine geology • CACHE-PEP RRS James Clark Ross Cruise JR179 Scientific Programme • Stanley – Stanley (inc. last call Rothera) • 19th February – 10th April 2008 • Involves three BAS core projects: BIOFLAME-BIOPEARL – marine biology

  2. P I B W A I S E A I S South Pacific and West Antarctic Topography ? Topography data north of 72oS courtesy of W.H.F. Smith (NOAA) Antarctic topography data from SCAR Antarctic Digital Database

  3. Quaternary West Antarctic Deglaciations (QWAD): • Objectives • How large was the glacial maximum ice sheet? • Retreat of the ice sheet • Thinning of the grounded ice sheet • Relative sea level change at the periphery of the ice sheet • Evidence for earlier Quaternary instability of the ice sheet

  4. Pole-Equator-Pole (PEP) • Objective • High-resolution records of climate over past 10,000 years

  5. NOCS piston corer NOCS multicorer Box corer Multibeam echo sounder TOPAS sub-bottom profiler Conductivity-temperature-depth (CTD) system Marine Geological Equipment Dredge Acoustic Doppler Current Profiler Expendable bathythermograph (XBT) probes Towed magnetometer Shipboard Three-Component Magnetometer

  6. Shipboard Scientific Party QWAD – 5 GSD scientists + 3 students (through CGS) PEP – 1 GSD scientist + 1 GSD technician + 1 student (through CGS) BIOPEARL – 4 BSD scientists + 1 scientist from NHM (through CGS) LTMS-B – 2 BSD scientists IPY-CAML – 2 international collaborators NMF – 1 technician BAS AME/ICT – 2 technicians TOTAL = 23

  7. Summary • Seven week research cruise to Amundsen and Bellingshausen seas, serving three BAS core projects (10 days science time each). • to look for evidence of past ice sheet instability • to obtain high-resolution palaeoclimate records • to study deep-water benthic biological communities
