Title:
Currents in Kaneohe Bay, Oahu, Hawaii 2005 - 2007 in Support of Fresh Water Plume Studies Performed by the Department of Oceanography at the Univesity of Hawaii (NODC Accession 0040251)
Abstract:
Freshwater plumes from rain run-off into Kaneohe Bay is the focus for the investigation. Measurements in this data set are currents as measured by an moored Acoustic Doppler Current Profiler (ADCP) and a Nortek current meter. Data were collected during November 2005 - March 2007 by members of the Department of Oceanography at the University of Hawaii. The ADCP sensor includes temperature at the transducer depth of 13 m. The Nortek current meter included ancillary measurements including temperature and pressure.

Temperature and salinity data taken at 24 stations as part of this project are available from NODC accession 0039532.

Why was the data set created?

Data from this study were supportive in describing the temporal and spatial variability of freshwater plumes from Kaneohe Stream, Hawaii, USA, following storm events in the Kaneohe Bay watershed.

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)
    The Teledyne RDI ADCP is an upward-looking instrument mounted at 13m depth. It was deployed over two four-month periods centered on the rainy season. Measurements of current velocity in three-dimensions and acoustic backscatter intensity were made at 1 m intervals from 2 m above the bed to the surface. The ADCP averaged 50 pings every ten minutes and provided observations of current magnitude and direction at 13-15 different elevations above the bottom.

    The Nortek current meter (Aquadopp 3D with Aquafin) was deployed at 2 m depth over two four-month periods in-line with a thermistor chain.
