Interdecadal changes in intensity of the oxygen minimum zone off Concepción, Chile (~ 36° S), over the last century

Creator:: Srain, B., Pantoja, S., Sepúlveda, J., Lange, C. B., Muñoz, P., Summons, R. E., McKay, J., and Salamanca, M.
Abstract:: We reconstructed oxygenation changes in the upwelling ecosystem off Concepción (36° S), Chile, using inorganic and organic proxies in a sediment core covering the last ca. 110 years of sedimentation in this area. Authigenic enrichments of Mo, U and Cd were observed between ca. 1935 and 1971 CE, implying a...

Artificial means of distinguishing smooth-line map unit boundaries : an examination of Oregon soil survey maps

Creator:: Yulin, Sun and Noller, Jay S.
Abstract:: This data set is used in the Master thesis of Yulin Sun (2017). It contains geospatial vector data (shapefiles), Microsoft Excel spreadsheets, and Portable Document Format (PDF) files. The geospatial vector data include both the data of original soil delineations and that of the convex hull of individual soil delineations....

Quantification of Habitat and Community Relationships among Nearshore Temperate Fishes Through Analysis of Drop Camera Video

Creator:: Easton, Ryan R., Heppell, Selina S., and Hannah, Robert W.
Abstract:: Temperate nearshore reefs along the Pacific coast of North America are highly valuable to commercial and recreational fisheries yet comprise a small fraction of the seabed. Monitoring fisheries resources in this region is difficult; high-relief structural complexity and adverse sea conditions have led to a paucity of information on temperate...

GRACE storage-streamflow hystereses reveal the dynamics of regional watersheds

Creator:: Sproles, E. A., Leibowitz, S. G., Reager, J. T., Wigington, P. J. Jr., Famiglietti, J. S., and Patil, S. D.
Abstract:: We characterize how regional watersheds function as simple, dynamic systems through a series of hysteresis loops. These loops illustrate the temporal relationship between runoff and terrestrial water storage using measurements from NASA's Gravity Recovery and Climate Experiment (GRACE) satellites in three regional-scale watersheds (>150 000 km² ) of the Columbia...

A new instrument to measure plot-scale runoff

Creator:: Stewart, R. D., Liu, Z., Rupp, D. E., Higgins, C. W., and Selker, J. S.
Abstract:: Accurate measurement of the amount and timing of surface runoff at multiple scales is needed to understand fundamental hydrological processes. At the plot scale (i.e., length scales on the order of 1–10 m) current methods for direct measurement of runoff either store the water in a collection vessel, which is...

Patterns of loggerhead turtle ontogenetic shifts revealed through isotopic analysis of annual skeletal growth increments

Creator:: Ramirez, Matthew D., Avens, Larisa, Seminoff, Jeffrey A., Goshe, Lisa R., and Heppell, Selina S.
Abstract:: Ontogenetic changes in resource use often delimit transitions between life stages. Ecological and individual factors can cause variation in the timing and consistency of these transitions, ultimately affecting community and population dynamics through changes in growth and survival. Therefore, it is important to document and understand behavioral and life history...

The VAMOS Ocean-Cloud-Atmosphere-Land Study Regional Experiment (VOCALS-REx): goals, platforms, and field operations

Abstract:: The VAMOS Ocean-Cloud-Atmosphere-Land Study Regional Experiment (VOCALS-REx) was an international field program designed to make observations of poorly understood but critical components of the coupled climate system of the southeast Pacific. This region is characterized by strong coastal upwelling, the coolest SSTs in the tropical belt, and is home to...

Non-Invasive Sampling of Schistosomes from Humans Requires Correcting for Family Structure

Creator:: Steinauer, Michelle L., Christie, Mark R., Blouin, Michael S., Agola, Lelo E., Mwangi, Ibrahim N., Maina, Geoffrey M., Mutuku, Martin W., Kinuthia, Joseph M., Mkoji, Gerald M., and Loker, Eric S.
Abstract:: For ethical and logistical reasons, population-genetic studies of parasites often rely on the non-invasive sampling of offspring shed from their definitive hosts. However, if the sampled offspring are naturally derived from a small number of parents, then the strong family structure can result in biased population-level estimates of genetic parameters,...
