I investigated the emergence of marine benthic harpacticoid and cyclopoid copepods from subtidal sediment into the bottom water. Previous field studies with traps found that copepods emerge from the sediment within 2 h of dusk. I examined emergence in 20-min periods from 1200 h to 0100 h (13 h) in a laboratory flume under conditions of constant flow velocity and in-situ salinity and temperature. Light intensity was adjusted to field conditions every 20 min. I observed the largest peak in benthiccopepod emergence during the 20-min sampling period corresponding to the onset of darkness. This result will help set the stage for studies of emergence cues. The synchronicity of emergence observed in our study may be an antipredation strategy to swamp potential predators, reducing the probability of any one individual being consumed. / A Thesis Submitted to the Department of Oceanography in Partial Fulfillment of the Requirements for the Degree of Master of Science. / Fall Semester, 2003. / July 31, 2003. / Laboratory Study, Flume, Copepod, Benthic / Includes bibliographical references. / David Thistle, Professor Directing Thesis; Joel Kostka, Committee Member; Nancy Marcus, Committee Member.
