Oceanographic conditions around the Galápagos Archipelago and their influence on cetacean community structure

Creator:: Palacios, Daniel Mauricio
Abstract:: The objectives of this dissertation were to describe the complex oceanographic conditions around the Galápagos Archipelago (eastern equatorial Pacific), their seasonal variability, and their effects on patterns of cetacean occurrence. The physical and ecological factors leading to a plume of high phytoplankton biomass in the wake of the Galápagos were...

Latitudinal distribution, calf growth and metabolism, and reproductive energetics of gray whales, Eschrichtius robustus

Creator:: Sumich, James L.
Abstract:: Gray whales accomplish an annual migration which spans as much as 50° of latitude in the northeast Pacific Ocean. This migration links their summer high latitude feeding grounds with winter calving and breeding areas. The purpose of this study was to determine how adult females apportion their stored lipid reserves...

Comparative study of the population dynamics, secondary productivity, and reproductive ecology of the euphausiids Euphausia pacifica and Thysanoessa spinifera in the Oregon upwelling region

Creator:: Gutierrez, Jaime Gomez
Abstract:: I compare the seasonal abundance variation, population dynamics, fecundity, egg hatching mechanism and success, and apostome ciliate parasites of the euphausiids Euphausia pac?fica and Thysanoessa spinfera from the Oregon coast, USA. Community structure and nearshore distributions were examined from bi-weekly oceanographic surveys (1970-1972). This region has a strong cross-shelf change...

Distribution, Abundance, and Settlement of Slope-spawning Flatfish during Early Life Stages in the Eastern Bering Sea

Creator:: Sohn, Dongwha
Abstract:: Changes in environmental conditions in marine ecosystems could directly or indirectly influence distribution, abundance, settlement, and size at settlement of flatfish. Understanding species-specific and age-specific responses to environmental variability is important for managing commercially important flatfish stocks. Slope-spawning flatfish whose offspring rely on extensive drift from the slope (spawning) to...

Tectonics of the East Pacific Rise, 5⁰ to 12⁰S

Creator:: Rea, David K.
Abstract:: The portion of the East Pacific Rise (EPR) between 5° and 12°S can be subdivided into three areas by fracture zones that offset the rise axis at about 6.5°S and 9°S. In all three regions, the spreading axis of the EPR is defined by a topographic block 300 to 350...
