Why was the data set created?

As part of an integrated study to assess projected impacts of land-use and climate change on nearshore habitat conditions and coral health, the U.S. Geological Survey (USGS) Pacific Coastal and Marine Science Center (PCMSC) initiated an investigation of nearshore water properties and coral health indicators along the west Hawaii Island coast. The project and data generated provide fundamental baseline data to track change and important boundary condition data to interpret characteristics of coral health related to water quality along a gradient in exposure to urban impacts and submarine groundwater discharge.

How was the data set created?

  1. From what previous works were the data drawn?
  2. How were the data generated, processed, and modified?
    Date: 09-Nov-2011 (process 1 of 1)
    Data were collected by divers on scuba along three randomly selected swath transects at each site location. The location where divers descended at the beginning of each transect was noted using a portable GPS unit in a waterproof housing. Once at the seafloor, a bearing was noted for the direction the divers swam and distance from start to each station noted along a 10-m measuring tape. Data observed along the transects were noted on divers’ slates using underwater paper.
  3. What similar or related data should the user be aware of?

How reliable are the data; what problems remain in the data set?

  1. How well have the observations been checked?
    No formal attribute accuracy tests were conducted.
  2. How accurate are the geographic locations?
    Stated horizontal accuracy of the Garmin GPS is +/- 3.2 m.
  3. How accurate are the heights or depths?
    Stated vertical accuracy of the Suunto Dive Computer is+/- 0.3 m.
  4. Where are the gaps in the data? What is missing?
    Data are complete as presented. Users are advised to read the rest of the metadata record carefully for additional details.
  5. How consistent are the relationships among the observations, including topology?
    No formal logical accuracy tests were conducted.

How can someone get a copy of the data set?
