—2. Plus 59 jars of additional dried material (200 g each) from samples included in the above count. Initial processing phase complete as of 23 February 1973. Vegetation, other terrestrial biota (3002 samples to be processed): Initial processing (LLL) - 138 vegetation samples completed. Seawater (58 samples collected): Chemical separation (LLL) - total of 58 samples; adding carriers and tracers, sequential separation of various elements; in process with a rate of 8-12 samples per week anticipate 6 weeks of additional effort. Plankton (17 samples collected): 17 samples in process (LLL) - dry, weigh, package. Core samples (36 samples collected): Total of 36 collected. In various stages of processing at LLL. These are being sectioned into 5-cm slices, dried, ground, and analyzed. A total of 165 samples will result from 36 cores. Air filters (61 samples collected): High-volume samples gamma counted (LLL) ~- 11 samples. Wet chemical analysis for 239py (MCL) - 7 (in process). Remainder will be processed as soon as results are in on first batch. Gamma counting, precision Ge(Li) detector spectroscopy: t
