Estimation of the feedback parameters in a closed-loop system : a geophysical problem

Creator:: Cid, Luis Serrano
Abstract:: The presence of feedback in an inputoutput system associated with an oceanographic phenomenon is determined. A testing procedure to determine the presence of feedback is given. The ordinary transfer function model is determined not to be appropriate in modeling the system. The two and three stage least squares methods are...

A study of El Niño/southern oscillation : numerical experiments and data analysis

Creator:: Ahn, Joong Bae
Abstract:: For the purpose of investigating the fundamental nature of the interannual oscillation observed in the tropical Pacific in conjunction with El Nino/Southern Oscillation (ENSO), the Comprehensive Ocean Atmosphere Data Set was analyzed. Based upon this analysis, an "intermediate" tropical atmosphere-ocean coupled model was developed. For reason of their particular importance...

Simulation of tropical pacific circulation anomalies with linear atmosphere and ocean models

Creator:: Dixit, Sanjay
Abstract:: A simple atmosphere and ocean model of relevance to El Nino and Southern Oscillation (ENSO) is discussed. Both the atmosphere and ocean models are two layer, three dimensional, linear and baroclinic, and generally follow the Oregon State University coupled general circulation model. However, the parameterization differs considerably from previous work...

El Nino related variations in nutrient and chlorophyll distributions off Oregon

Creator:: Corwith, Holly L.
Abstract:: The Oregon continental shelf waters are typically characterized by four to five major upwelling events that occur between May and October. The upwelled water is rich in nutrients, which fuels an increase in phytoplankton biomass. The onset of El Nino, however, can disrupt the normal physical processes along the Oregon...

Current measurements off the west coast of South America: November 1981 - March 1985

Creator:: Knoll, Michaela, Paluszkiewicz, Theresa, Pittock, Glenna, Still, Robert E., Smith, Robert L., and Huyer, Adriana
Abstract:: Several current meter moorings were deployed over the continental margin of Peru along 5° and 10°S to study the Peru current system. The observation period from November 1981 to March 1985 covered the occurrence of El Nino 1982-83. This report presents the six-hourly low-passed data sets of each mooring. Progressive...

ENSO impacts on pelagic ecosystems in the Eastern Pacific, with emphasis on fishery resources

Creator:: Alvial, Adolfo L.
Abstract:: Many new research and monitoring projects, developed or initiated during ENSO 1982-83, constituted detailed descriptions of changes in specific taxa or specific processes. However, only a few projects were opportunely started or continued as regional efforts in the eastern Pacific. For those reasons, the information obtained is difficult to compare....

Oceanographic effects on the dynamics of food habits and growth condition of some groundfish species of the Pacific Northwest

Creator:: Lee, Yong Woo
Abstract:: Marine fish are subject to direct and indirect oceanographic variations operating at short and long time scales. In this study feeding habits and long-term growth condition of several groundfish species of the Pacific Northwest are examined to understand the relationship between variations in the fish's biological and life history components...

The role of herbivores and productivity on community structure of rocky shores of the Galapagos Islands, Ecuador

Creator:: Vinueza, Luis R.
Abstract:: Ecosystems are facing increasing threats from human related activities, such as overfishing, pollution, habitat destruction, species invasions, and diseases, among others. While oceanic islands provide natural laboratories to understand ecological and evolutionary process, they are also particularly vulnerable to these impacts, given their usual isolation from the mainland and the...
