A high-resolution numerical model with idealized topography is used to investigate the degree to which a coastal upwelling jet separates from the shelf as it flows around a submarine bank depending on the wind strength and the horizontal scale of the bank. Experiments were run using several wind forcing magnitudes...
Data from the SeaWinds scatterometer on the
QuikSCAT satellite are used to estimate upwelling around
Cabo Frio, Brazil, due to Ekman transport and Ekman
pumping. The region close to shore (up to 200 km from the
coast) is characterized by negative wind stress curl
(upwelling favorable) year-round, with maximum values...
Repeated mesoscale surveys of waters over the shelf and slope off Oregon were
conducted during spring and summer of 2001 to study the spatial structure of the velocity
and hydrographic fields. The ocean response to wind forcing is compared between a
region of relatively simple topography with alongshore uniformity and...
Data from Geostationary Operational Environmental
Satellites are used to study the seasonal evolution of
temperature fronts in the northern California Current
System (CCS), focusing on the interactions with
topographic features. Fronts first appear close to the coast
in response to upwelling winds, moving offshore with the
continuous input of energy...
Sea surface temperature (SST) fronts are determined for the 2001–2004 time period
from Geostationary Operational Environmental Satellites (GOES) data in the California
Current System (CCS). The probability of detecting a SST front at an individual pixel
location in the CCS is presented as a bi-monthly climatology. Fronts clearly indicate the...
The effects of alongshore variability in topography (banks and capes) and spatial variability in the wind forcing, including the wind-stress curl, on coastal ocean circulation are studied using a combination of observations and model simulations. Satellite sea surface temperature observations are used to describe the seasonal evolution of temperature fronts...
Recently generalized Fibonacci numbers have received increasing attention. Some properties that are well known for traditional Fibonacci numbers do not generalize easily, some others do not generalize at all. In this paper we report some properties that we have generalized. Section 1 introduces the notation and a theorem due to...
During summer 2001, high-resolution hydrographic, velocity, and bio-optical surveys
were conducted over Heceta Bank off central Oregon. North of the bank, upwelling
over simple bottom topography exhibited a classic response with a midshelf, baroclinic
coastal jet and upwelled isopycnals. The coastal upwelling jet follows the bank
topography as it widens...
It is well known that the Fibonacci numbers can be expressed in the
form Round {1/√5 λ₀[superscript n]} where λ₀ = (1 + √5)/2. [Knu75] We look at integer sequences which are solutions to non-negative difference equations and show that if the equation is 1-Bounded then the solution can be...
The study of the effects of diethyldithiocarbamate (DEDTC) in some diseases is in focus for many years. However, DEDTC is a metal chelator that can present neurotoxicity as side effects. Here we investigate the effect of DEDTC on brain Zinc (Zn) content and behavior. To address this issue we used...
