Abstract: A radar experiment was conducted on August 18,
é
at Kwajalein
1978,
Atoll, Marshall Islands, to investigate the spatial relationship of l1-m
equatorial spread F irregularities to plasma bubbles (localized
depletions in F layer plasma density). East-west scans were made with
Altair,
an incoherent scatter radar,
to spatially map
(1)
the
backscatter produced by field-aligned irregularities and (2) the
electron density distribution of the background F layer. Plasma bubbles
were spatially mapped for the first time with an incoherent scatter
radar. By assuming invariance along the magnetic field lines (over
distances of less than 100 km) we show that 1-m field-aligned
irregularities are directly related to plasma bubbles.;

technique are compared with a radiochemical coprecipitation method.
Consistent results were obtained between the two methods for water
samples from the Pacific Ocean and Eniwetok lagoon. Different results
were noted from samples collected in the Eniwetok reef and groundwater
stations. We were able to demonstrate, using this preconcentration
technique and the coprecipitation method, that the physical-chemical
characteristics of Pu in Eniwetok reef and groundwater are different
from the lagoon and open ocean.;
