Broadband body waves recorded at 15 digital seismic stations worldwide are used to study the rupture process of the May 23, 1989 Macquarie Ridge earthquake. The centroidal solution (strike 211°, dip 86°, rake 180°, and depth of 10 km below the seafloor) indicates shallow rupture with pure right-lateral strike-slip motion...
We quantified both in situ predation on Pacific herring (Clupea haregus pallasi ) larvae by soft-bodied zooplankton, and microzooplankton prey of herring larvae in Kulleet Bay, Vancouver Island, British Columbia. Samples were collected at 0 to 5 m depth daily at peak larval hatching from 14 to 21 April 1985....
Control charts are designed to monitor population parameters. Selection of a
control chart sampling plan involves determination of the frequency of samples, size
of each sample, and critical values to determine when the system is sending an out-of-control signal. Since the main use of control charts is in industry, a...
