Surface transports into the California Current are calculated from TOPEX/POSEIDON altimeter surface height slopes during the 9.5 year period from October 1992–May 2002. These quantify the anomalous onshore and southward displacements of the water column during the 2000–2002 period, which had been hypothesized by others based on anomalous water properties...
In this paper, we evaluate the temporal and horizontal resolution of geostrophic
surface velocities calculated from TOPEX satellite altimeter heights. Moored velocities
(from vector-averaging current meters and an acoustic Doppler current profiler) at depths
below the Ekman layer are used to estimate the temporal evolution and accuracy of
altimeter geostrophic...
Satellite-derived data provide the temporal means and seasonal and nonseasonal
variability of four physical and biological parameters off Oregon and Washington
(41°–48.5°N). Eight years of data (1998–2005) are available for surface chlorophyll
concentrations, sea surface temperature (SST), and sea surface height, while six years of
data (2000–2005) are available for...
Two methods of estimating surface velocity vectors from advanced very high resolution radiometer (AVHRR) data were applied to the same set of images and the results were compared with in situ and altimeter measurements. The first method used and automated feature –tracking algorithm and the second method used an inversion...
Two ocean general circulation models are used to test the ability of geostrophic velocity measurement systems to observe the meridional overturning circulation (MOC) and meridional heat transport (MHT) in the South Atlantic. Model sampling experiments are conducted at five latitudes (between 15° and 34.5°S) spanning the range of extratropical current...
Geologic carbon sequestration is being considered in target basalt and sandstone formations. The chemical
effects of CO2 exposure on the interface between Class H Portland cement paste and Grande Ronde
Columbia River basalt, or between cement paste and Mt. Simon sandstone, has been examined at a
microstructural level. This bonding...
We evaluate the impact of the Gambian hardship allowance, which provides a salary premium of 30‐40% to primary school teachers in remote locations, on the distribution and characteristics of teachers
across schools. A geographic discontinuity in the policy’s implementation and the presence of common
pre‐treatment trends between hardship and non‐hardship...
Satellite‐derived sea surface salinity (SSS) data from Aquarius and SMOS are used to study the shelf‐open ocean exchanges in the western South Atlantic near 35°S. Away from the tropics, these exchanges cause the largest SSS variability throughout the South Atlantic. The data reveal a well‐defined seasonal pattern of SSS during...
Altimeter sea surface height (SSH) fields are analyzed to define and discuss the seasonal circulation over the wide continental shelf in the SW Atlantic Ocean (27°–43°S) during 2001–2012. Seasonal variability is low south of the Rio de la Plata (RdlP), where winds and currents remain equatorward for most of the...
Recent trends in librarianship point to themes of crafters, artisans, and makers in library spaces. The American Library Association's Center for the Future of Libraries includes the Maker Movement as one of its trends. Librarians can support these makers and entrepreneurs by thinking of libraries as a place to create...
