Over the continental shelf at 15°S off Peru, sigma-t is a well-defined
function of temperature (Figure 1) and hence temperature alone may be used
to monitor the changes in stratification, to test the thermal wind equation,
and to monitor the hydrographic response to wind events. In this report we
present...
Salinity, temperature, oxygen phosphate, nitrate and silicate
observatIons were taken by Oregon State University on 21 hydrographic
cruises in the Northeastern Pacific Ocean during 1968. Alklinity , pH
and total CO2 were taken on special occasions. Fifteen cruises were
taken along the Newport line. The rest were special cruises made...
Salinity, temperature, oxygen, phosphate, nitrate and silicate
observations were taken by Oregon State University on 17 hydrographic
cruises in the Northeastern Pacific Ocean during 1966. Alkalinity, pH
and total CO2 were taken on special occasions. Nine cruises were
taken along the Newport line. The rest were special cruises made
off...
This is the fourth data report of a study designed to determine
the current patterns and water mass characteristics along the
Oregon coast.
All data in this report were collected at stations occupied by
Research Vessel ACONA (Burt and Pattullo, 1961). The
This is the third data report of a study designed to determine the
current patterns and water mass characteristics along the Oregon coast.
The first report covered the period July 1958 to July 1959 (Wyatt and
Callaway, 1961). During that year observations were taken to a maximum
depth of 30...
Diatom floral analysis of 116 sediment surface samples obtained off Peru reveals a boundary in the sediments between coastal upwelling influenced sediments and sediments outside the highly productive realm. Sinuous patterns of relative abundance for meroplanktic species (Actinocyclus octonarius, Actinoptychus senarius, and Cyclotella striata/stilorum) may preserve the meander-like patterns of...
Oregon State University installed and recovered moorings along the coast of Peru during the period late March 1976 through mid-May 1977. A mid-shelf mooring near 15°S (MILA)
was maintained for the full duration of the experiment, through five successive installations. This site was complemented by six other moorings in the...
Recent organic-rich deposits on the Peru continental margin
occur along the upper slope (100-450 m) between about ll°S and 16°S
and along the lower continental slope (>2000 m). The upper slope
deposits reflect high biological production in response to coastal
upwelling, but preservation of organic matter is enhanced by the...
