Population dynamics of Skeletonema costatum in high dilution rate chemostats

Creator:

Donaghay, Percy L.

Abstract:

A chemostatic system was developed for the long term studies of population dynamics of chain forming diatoms. Vessel volume rather than flow rate was varied in these systems to obtain different growth rates at steady state in systems with an equal capacity to produce. Population level responses to high dilution...

Vertical current measurement in the Oregon coastal upwelling region

Creator:

Deckard, Dennis E.

Abstract:

Direct measurements of vertical water motions were made in the Oregon coastal region during the 1972 summer upwelling season. The instruments used were the Webb-Voorhis vertical current meters which are freely drifting neutrally buoyant floats capable of sensing vertical motion. It was found that in the region studied, water tended...
