An impounded estuary was employed to study primary productivity, community respiration, and community structure as they
related to seasonal and temporal succession, salinity, and water
temperature. Plankton metabolism was studied by means of the
light-and dark-bottle technique. Benthic community metabolism
was determined by using the "diurnal oxygen curve" method.

Samples of benthic organisms off the coast of Oregon, taken
from depths varying from 50 to 2900 meters, have been analyzed in
terms of diversity at a given station, and similarity and ecological
distance to other stations. Estimates of epifauna abundance were
also made. In the analysis an important distinction...
Netarts Bay is a coastal lagoon on the northern Oregon coast. Four major sedimentary environments are recognized including channel, sand flats, mud flats, and marsh. Fine-grained sediment is carried in by streams and deposited in the marshes and mud flats. Fine sand for the channel and sand flats is derived...
Studies on elemental and energy transfer in lower trophic levels in
the marine environment were initiated in July 1962 after receipt of AEC
contract AT(45-1)1751. It should be pointed out that this report covers
only a six-month period, because for bookkeeping purposes the contract
was made retroactive to 1 April...
A study of the effect of mixing on the oxygen uptake rate of
estuarine bottom deposits is presented. The method of study involved
the mixing of samples of bottom deposits with the overlying water to
result in concentrations of suspended matter in the same order as
observed in the estuary....
