Accumulation rates and chemical compositions of material collected in particle interceptor traps (PIT's) compared favorably with the naturally- calibrated laminated and preserved bottom sedi- ments of 3 California basins; the PIT design appears to collect a representative sample and provide a good estimate of particle flux.

Determinations of sediment flux and composition were similar for 4 traps of radically different design: paired cones, folding box, cylinder, closing box. These are encouraging results for directly measuring oceanic particulate flux. Oregon State Univ., Cor- vallis, Oreg. 97331, USA. (dme)

Classical geodetic methods are insufficiently accu- rate to measure tectonic plate movement and deformation, in addition to being impractical and prohibitively expensive at the level of detail required. Long-baseline microwave int, rferometry and laser ranging to satellites are two space-based techniques which show promise of attaining movement meas- urement accuracies within 2-3 cm in the very near future. Coordinated national and international re- search programs are underway to study polar motion, plate movements, Earth rotation, crustal deformation, etc. NASA, Geodynamics Program, Washington, D.C. 20546, USA.

A relatively small self-contained sediment trap with a timed closing system was deployed in Dabob Bay, Washington, for 1 yr. An in-situ calibration was obtained by comparin$ the capture and retention of unsupported 2z°Pb by the traps with the steady state accumulation rate of unsupported 21°Pb in the

underlying bottom. Dept. of Oceanography WB-10, Univ. of Washington, Seattte, Wash. 98195, USA.

Tectonism, volcanism, glaciation, and sedimentation have shaped the shelf morphology of the Ross Sea. Seafloor provinces are described geologically, geo- physically, hydro-glaciologicatly and sedimento- logically. Some plate reconstruction models are discussed.
