  15. Title: Sea Surface Temperature Anomaly, 2007-2008

    Contributors:

    Summary: This raster dataset is a model that measures the impact of sea surface temperature anomalies as a factor in global climate change. Potential for ecological change in response to changes in sea surface temperature can be measured as the frequency of temperature anomalies, where the temperature exceeds a threshold value like the long-term mean, or by a measure of the magnitude (°C) of the anomalies themselves.

  17. Title: Artisanal Fishing, 2007-2008

    Contributors:

    Summary: This raster dataset is a global model of artisanal fishing based on small scale fisheries data and population proximity to coastal areas. See the Lineage section for complete information regarding data sources and processes. This approach to estimating the impact of artisanal fishing cannot distinguish between methods that do and do not modify habitat. Some developing nations have a high rate of habitat-modifying artisanal fishing and our estimate of the impact of this activity in those locations will be underestimated. Unfortunately, the distribution of habitat-modifying fishing methods is currently unknown in a globally-comparable way. Artisanal fishing is notoriously difficult to estimate our approach uses coarse FAO estimates, models missing national data, and then models the small-scale distribution of national data. This dataset is part of the Global Map of Human Impacts to Marine Ecosystems, a collection of data and analyses related to anthropogenic drivers of change in marine ecosystems. The goal of this research is to estimate and visualize the global impact that humans are having on the oceans' ecosystems. National Center for Ecologial Analysis and Synthesis.

  20. Title: Ocean Acidification, 2007-2008

    Contributors:

    Summary: This raster dataset depicts the measurements of ocean acidification at global coverage. Changes in CO2 concentration alter the aragonite saturation state (ASS) of the ocean, among other chemical properties of seawater, and as ASS levels drop the ability of calcifying species such as corals, diatoms, and shelled invertebrates to create calcium carbonate structures declines. The global distribution of ASS values has been modeled at 1-degree resolution for pre-industrial (circa 1870) and modern times (2000-2009). We use the difference between these values as an estimate of the human-derived driver of changes in ocean acidification. This dataset is part of the Global Map of Human Impacts to Marine Ecosystems, a collection of data and analyses related to anthropogenic drivers of change in marine ecosystems. The goal of this research is to estimate and visualize the global impact that humans are having on the oceans' ecosystems. National Center for Ecologial Analysis and Synthesis.
