In 1960 a program of monitoring the zooplankton populations of Yaquina Bay, Oregon, was begun. The frequency of sampling was maintained at close to weekly intervals after 1 January 1963, usually at five stations. Abundances of all the species found in the bay of both meroplankton and holoplankton have been...
Lamellar x-ray diffraction was studied from thin films of L-α-1,2-dipalmitoyl lecithin (DPL) and a 1:1 mixture (BrDPL) of L-α-l-palmitoyl-2-(9- bromopaimitoyl) lecithin and its 10-bromo analog. The specimens had high lamellar order, with an upper bound on the mosaicity of 6 mrad (0.4°) for DPL and BrDPL. With various water contents,...
A workshop was held in Santa Barbara, California, associated with assessing the populations of nekton animals such as squids, shrimps and fishes. Sessions four major methods of assessing nekton populations:
(1) Net collections
(2) Acoustics
(3) Egg/larval surveys
(4) Visual methods, remote sensing and feeding habit studies
An attempt was...
Eleven hand specimen whole rock (WR) samples (25-200 g each) and
33 fragments (0.5-0.8 g each) from a single basaltic flow at Picture
Gorge, Oregon were analyzed via instrumental neutron activation
analysis (INAA) for 12 elements (Na, Fe, Cr, Sc, Co, La, Sm, Eu, Yb,
Lu, Hf and Ta). Standard...
