Title:
Water temperature time-series data from nearshore coral reef and anchialine pool locations along the west coast of Hawaii Island (2010-2013)
Abstract:
Time-series data of water temperature were collected at 33 locations along the west coast of the Island of Hawaii, including within Kaloko-Honokohau National Historical Park (KAHO), and Puu o Honaunau National Historical Park (PUHO) between 2010 and 2013 in nearshore coral reef and anchialine pool settings. Temperature sensors were attached to fossil limestone, rock or dead coral within otherwise healthy coral reef settings spanning water depths of 0.1 to 8.84 m (0.3 to 29.0 ft). Continuous measurements were made every 10 or 20 minutes. Due to the large amount of data, the dataset has been split into three files. WaterTempTimeSeries_KAHO-KC.csv includes data from nearshore coral reef locations within Kaloko Bay, which lies within the KAHO boundaries; WaterTempTimeSeries_KAHO.csv includes data from nearshore reef locations and two anchialine pools within the remainder of KAHO; WaterTempTimeSeries_westHawaii.csv includes data from nearshore coral reef locations along west Hawaii coastline, outside of the KAHO boundaries.

Why was the data set created?

Continuous quantitative data from a range of depths and distances from shore were collected to characterize the temporal and spatial variability in water temperatures that influence coral reef habitats, coral health and the vulnerability of coral to bleaching. These data also establish important baseline information with which to track and identify changes owing to climate and land use change, including changes in runoff of terrestrial water and contaminants that can affect the quality of habitat for corals, fish and other wildlife of concern. Along the arid west coast of Hawaii Island terrestrial inputs of water occur primarily in the form of groundwater and this study focused on examining the extent that groundwater inputs to the coast influences coral reef water temperatures, coral health, and potential cold water refugia where corals may find resilience in light of observed increases in global coral bleaching associated with rising sea surface temperatures.

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: 2016 (process 1 of 3)
    Hobo Temperature Pro V2 data loggers were attached to the seafloor beginning in June 2010. Continuous measurements of water temperature were made throughout sequential instrument turn-arounds and deployments until December 2013. Outliers associated with sensor out of water were removed. Data were not collected at every site during each time period; missing data are indicated by NaN.
    Date: 19-Oct-2020 (process 2 of 3)
    Edited metadata to add keywords section with USGS persistent identifier as theme keyword. No data were changed. Person who carried out this activity:

  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?
    Stated temperature accuracy of the Hobo Temperature Pro V2 data logger is +/- 0.21 degrees Celsius. 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. Data were not collected at every site during each time period; missing data are indicated by NaN. 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.
