Bioenergetics and behavior of the krill Euphausia pacifica in the California Current System off the Oregon coast

Creator:: Lindsey, Brie J.
Abstract:: Euphausia pacifica, the North Pacific krill, is a key grazer in the California Current System and an important prey item for consumers such as salmon, seabirds, and whales. As a crucial link between phytoplankton and higher trophic levels, it is essential to understand both the behavior and bioenergetics of this...

Transport of the copepod, Calanus finmarchicus, in the northwest Atlantic during diapause

Creator:: Kowalke, Gregory L.
Abstract:: The copepod Calanus finmarchicus is the most important and biomass dominant mesozooplankter in the temperate-boreal North Atlantic. C. finmarchicus has an overwintering phase, termed diapause, during which it descends to great depths (300-2000m) and is metabolically quiescent for up to ten months. Changes in the currents at depth due to...

Bioenergetics individual based model explorations of juvenile coho salmon growth during their first summer on the Oregon shelf

Creator:: Reser, Brendan Alexander
Abstract:: Salmon survival and eventual recruitment success have long been thought to be determined within the first summer following ocean migration. Juvenile growth during this period is largely influenced by ocean conditions such as temperature, prey availability, abundance, and quality. Shifts in these conditions due to climatic perturbations are particularly prevalent...

Phytoplankton balance in the oceanic subarctic Pacific: Grazing impact of Metridia pacifica

Creator:: Batchelder, Harold P.
Abstract:: Ingestion and respiration by Metridia pacifica, the dominant large copepod during autumn and winter in the subarctic Pacific, were investigated by shipboard and laboratory experiments. Diel variation in the rate of grazing on phytoplankton by M. pacifica was determined from measurements of gut pigment content and gastric evacuation rate. Both...

Forward-in-Time-/Backward-in-Time-Trajectory (FITT/BITT) Modeling of Particles and Organisms in the Coastal Ocean

Creator:: Batchelder, Harold P.
Abstract:: Lagrangian particle-tracking models (LPTMs) were used to identify sources, destinations, and transport pathways of particles (plankton). The LPTM simulations were forced using stored fields from the Spectral Element Ocean Model simulation for a coastal upwelling system having idealized geometry, bathymetry, and simple wind forcing. Forward-in-time-trajectory (FITT) simulations are common in...

Development, performance evaluation and application of a physical model of the Kenyan-Tanzanian coastal region

Creator:: Mayorga Adame, Claudia Gabriela
Abstract:: A Regional Ocean Modeling System (ROMS) application for the coastal region of Kenya and Tanzania (0-10° S, 38.7-46.98° E) was developed with the aim of better resolving the circulation patterns in the coastal region that is poorly represented in global models. The model has a horizontal resolution of 4 km,...

Modeled Larval Connectivity Patterns in two Coral Reef Regions : the Western Caribbean and the Kenyan-Tanzanian Shelf

Creator:: Mayorga Adame, Claudia Gabriela
Abstract:: Tropical coral reef ecosystems are very important from both the ecological and economical points of view. However, they are also particularly fragile, and have been declining in recent years in most regions of the world, since they are highly susceptible to anthropogenic stressors operating at global scales (e.g., global warming...

Zooplankton of the Galapagos Islands

Creator:: Figueroa, Diego
Abstract:: The marine climate of the Galapagos is spatially and seasonally heterogeneous. A taxonomically comprehensive study of Galapagos zooplankton has never been done. This study is an initial effort to establish the distribution and community structure of zooplankton in the Archipelago. I collected zooplankton samples by vertical tows over the Galapagos...

Modeling Transport, Retention, and Growth of Early Life Stages of Small Pelagic Fishes in the Southern Humboldt System

Creator:: Gomez, Fabian A.
Abstract:: Small pelagic fishes (SPF), such as anchovies and sardines, are ecologically important due to their large abundance and intermediate trophic position that links plankton production to upper trophic levels. They are also economically important, supporting large fisheries that contribute to one fourth of the world fish landings. Reproductive success in...
