Frequently anticipated questions:

What does this data set describe?

Moored ADCP Current Measurements from Mamala Bay, Oahu, Hawaii during 1997-1998 (NODC Accession 0000624)
A downward-looking moored ADCP instrument was deployed at the surface about a mile south of Honolulu Harbor in waters of about 280 feet. The instrument was in operation from May 1997 - August 1998, when it was tangled in the mooring line of a ship and made unoperational. The data are one-minute samples taken from 20 to 62 m at 2 m depth intervals. Primary processing was done by Oceanit. Michelle Eich, a graduate student at the University of Hawaii, applied quality control to select time periods of the data. Some of the other periods have remaining questionable features.

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: Unknown (process 1 of 1)
    ADCP mooring string deployed.

    Some of the data received quality control by Michelle Eich of the Oceanography Department at the University of Hawaii. Obvious spikes were replaced with missing data flags.

    Deepest two depth cells have questionable data quality due to proximity to the bottom.

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

  1. How well have the observations been checked?

  2. How accurate are the geographic locations?

  3. How accurate are the heights or depths?
