  16. Title: World (Ore deposits, 2003)

    • Point data
    • 2003
    Contributors:

    Summary: Ore deposits.MRDS contains variable-length records of metallic andnonmetallic mineral resources of the world. A recordcontains descriptive information about mineral deposits andmineral commodities. The types of information in the database include deposit name, location, commodity, depositdescription, geologic characteristics, production,reserves, potential resources, and references. The MineralResource Data System master database is not accessible viathe WWW. The large number of multi-valued fields make itdifficult to import all the fields into a data format thatcan be utilized by the ArcView Internet Map ServerSoftware. This dataset contains all MRDS locations, butonly 44 of the possible 226 fields. A data structure wascreated in Access 97. Data was imported into the filestructure and then processed into Arc View, where it wastransformed into shape files that are used by the IMSsoftware to serve the MRDS data and permit access via the www.

  17. Title: Ocean Tipping Points

    Contributors:

    Summary: The Ocean Tipping Points collaborative research project seeks to understand and characterize tipping points in ocean ecosystems. This idea is not new. Many scientists before us have studied the complex dynamics of marine ecosystems, highlighting the potential for rapid, dramatic changes in ocean conditions. However, past science has done little to influence the way we manage marine ecosystems. We have an opportunity to change this, as promising new science converges with a paradigm shift toward ecosystem-based management of our coasts and oceans. Tipping points occur when small shifts in human pressures or environmental conditions bring about large, sometimes abrupt changes in a system – whether in a human society, a physical system, an ecosystem or our planet’s climate. System requirements: Geographic Information Systems (GIS) software that reads GeoTIFF format.

  18. Title: Nitrogen Flux from Onsite Waste Disposal Systems

    Contributors:

    Summary: This raster data layer represents the nitrogen flux coming from onsite waste disposal systems (OSDS) (e.g. cesspools and septic tanks). OSDS point data was obtained from UH/DOH (Bob Whittier & El Kadi) that estimates nitrogen flux from each TMK parcel with OSDS. We converted the points to raster by summing nutrient flux values within 500 m x 500 m pixels. Then focal statistics was used to calculate the total flux within a 1.5 km radius of each oceanic cell. Units are in grams/day per km2. This layer was developed as part of a geospatial database of key anthropogenic pressures to coastal waters of the Main Hawaiian Islands for the Ocean Tipping Points project (http://oceantippingpoints.org/). Ocean tipping points occur when incremental changes in human use or environmental conditions result in large, and sometimes abrupt, impacts to marine ecosystems. The ability to predict and understand ocean tipping points can enhance ecosystem management. The goal of the Hawaii case study of the Ocean Tipping Points project was to gather, process and map spatial data on environmental and anthropogenic drivers of coral reef ecosystem states. Understanding direct anthropogenic drivers is critical for coral reef management and implementing policies to protect ecosystem services generated by coral reefs. Ocean Tipping Points Project. (2016). Nitrogen Flux from Onsite Waste Disposal Systems. Ocean Tipping Points Project. Available at: http://purl.stanford.edu/gh467sr9939. This layer is presented in the WGS84 coordinate system for web display purposes. Downloadable data are provided in native coordinate system or projection.

  19. Title: SST Long-term Mean, 2000-2013

    Contributors:

    Summary: Sea surface temperature (SST) plays an important role in a number of ecological processes and can vary over a wide range of time scales, from daily to decadal changes. SST influences primary production, species migration patterns, and coral health. If temperatures are anomalous warm for extended periods of time, drastic changes in the surrounding ecosystem can result, including harmful effects such as coral bleaching. This layer represents the mean sea surface temperature (SST) (degrees Celsius) of weekly time series from 2000 – 2013. A continuous, 5km gap-filled weekly SST data set available from 1985 – 2013 was produced from a variety of sources. Please see Lineage Statement for more details. This layer was developed as part of a geospatial database of key anthropogenic pressures to coastal waters of the Main Hawaiian Islands for the Ocean Tipping Points project (http://oceantippingpoints.org/). Ocean tipping points occur when shifts in human use or environmental conditions result in large, and sometimes abrupt, impacts to marine ecosystems. The ability to predict and understand ocean tipping points can enhance ecosystem management, including critical coral reef management and policies to protect ecosystem services produced by coral reefs. The goal of the Ocean Tipping Points Hawaii case study was to gather, process and map spatial information on environmental and human-based drivers of coral reef ecosystem conditions.

Please contact the Ocean Tipping Points project in advance of applying these data sets to project work so the PI can track and communicate data uses and ensure no duplicate efforts are underway. When applying these data for publication, please reference and cite the complete journal article, Wedding et al. 2017. This layer is presented in the WGS84 coordinate system for web display purposes.
