attribute NC_GLOBAL acquisition_description String These data include total anchovy and sardine biomass west and southeast of\nCape Agulhas (sampled in November), and anchovy and sardine recruitment west\nof Cape Infanta (sampled in May). Seabird variables included % of the diet\ncomprised of anchovy, % of the diet comprised of sardine, breeding success,\nand survival. African penguin data were collected at Dassen and Robben\nIslands, South Africa. Cape gannets data were collected at colonies on Malgas\nIsland and in Lamberts Bay, South Africa.\n \nThese variables were entered into path analyses, run in Stata v. 11.1\n(StataCorp). Path models were designed a priori with upwelling as the base\npredictor variable, fish biomass (both species) and anchovy recruitment as\nintermediate predictors, and a seabird metric as the response variable. Path\nanalysis produces beta coefficients for each path segment of the model. To\ndetermine the dominant path of effect, the beta coefficients for each indirect\npath were multiplied together, then summed. This sum of the products of all of\nthe indirect paths was compared to the beta coefficient of the direct path of\neffect. The greater value indicated if the dominant path was direct or\nindirect. If indirect, the path with the largest beta coefficient product was\nconsidered the dominant path of the model. Note that fish biomass, and anchovy\nrecruitment data were ln-transformed prior to analysis. Anchovy and sardine\nbiomass were lagged one year for analyses of penguin responses, to precede the\npenguin breeding season when those measurements were collected.

attribute NC_GLOBAL projects_0_description String Desciption from NSF award abstract:\nAlong the west coasts of North and South America, Africa, and Iberia, alongshore equatorward winds bring nutrient-rich waters to the sunlit surface of the ocean, stimulating phytoplankton blooms that support robust, rich and diverse ecosystems. This process is known as \"upwelling\". Because upwelling is driven by winds, and winds are related to atmospheric conditions, upwelling is highly vulnerable to the effects of climate change. However, the potential impacts of climate change on upwelling and biology remain largely uncertain. In earlier work in the California Current upwelling system, off the west coast of the United States, researchers found that upwelling occurs in distinct winter and summer \"modes\" that have different impacts on biology. In this project, oceanographic and atmospheric data from the Benguela Current system, off South Africa and Namibia, will be analyzed for similar seasonal patterns and relationships with the ecosystem. Comparisons between these two upwelling systems will allow researchers to investigate if previous findings of regional climate impacts on biology are applicable at a global scale and consider how these systems may change in the future. The project will facilitate collaboration between researchers from South Africa, Namibia, and the United States, integrating a team of young and senior scientists from the three countries and providing them with opportunities for broad-scale scientific synthesis early in their careers.\nThis project will be a comparative analyses of climate forcing and biological responses in the California Current (CCS) and Benguela Current systems (BCS), the two upwelling systems with the most similar time series of atmospheric and oceanographic conditions, seabird demography, and lower (chlorophyll) and mid (forage fish) trophic data. The project will determine whether changes in the ecosystems can be attributed to regional or global climate processes. Growth-increment chronologies from fish in the BCS (deep-water hake) will be developed as indicators of upper-trophic fish growth, and compared to rockfish growth chronologies developed in the CCS. Mid-trophic level fish abundance will be modeled as indices of prey availability for integration between climate and upper-trophic-level parameters. Oceanographic and atmospheric data will be analyzed from global observational and reanalysis data sets, as well as from earth system model projections of climate change. The project will address the following questions:\n1) are seasonal upwelling modes (winter and summer) discernible in the BCS as they are in the CCS?\n2) are upwelling modes forced by similar or contrasting atmospheric forcing mechanisms?\n3) is there evidence of coherence/covariance among mid-trophic fish, upper-trophic fish, and seabirds (and at which lags) within and between the CCS and BCS?\n4) will the positioning and amplitude of the atmospheric pressure systems that result in upwelling-favorable winds change coherently between ecosystems under various climate-change scenarios? and\n5) what are the fisheries and wildlife management implications for variability in the seasonality and spatial distribution of upwelling in a changing climate?
