Acoustic Mooring Data Taken during the TOGA COARE Intensive Observing Period (IOP)Entry ID: COARE_lso_mooring_acoustic
Abstract: DATA ACCESS
Thermistor chain data and limited acoustic instrument time series for
the acoustic mooring are available upon request from Steven Hill at
the Institute of Ocean Sciences in Canada.
TOGA COARE data is available from the TOGA COARE Data Information System
http://www.ncdc.noaa.gov/oa/coare/index.html, the NOAA National Oceanographic
Data Center http://www.nodc.noaa.gov, and the ... National Center for
Atmospheric Research (NCAR) in Boulder, CO
BACKGROUND - TOGA COARE
TOGA COARE was a multidisciplinary, international research effort that
investigated the scientific phenomena associated with the interaction
between the atmosphere and the ocean in the warm pool region of the
western Pacific. The field experiment phase of the program took place
from 1 November 1992 through 28 February 1993 and involved the
deployment of oceanographic ships and buoys, several ship and
land-based Doppler radars, multiple low and high-level aircraft
equipped with Doppler radar and other airborne sensors, as well as a
variety of surface based instruments for in situ observations.
The acoustic mooring was operated at 1 30 S, 155 45 E to estimate
surface winds, surface wave field, occurence of wave breaking and
rainfall, and entrainment of air and resultant organization and
distribution of bubble clouds.
The top of the acoustic mooring was approximately 30 m below the
surface. The mooring was equipped with the following instruments/
- ELSI acoustic instrument (four upward-looking sonars, four 100-kHz
side scan sonars, and a hydrophone)
- SeaCat at 30 m
- Interocean S4 current meter (34 m, sampling every 30 min, 2-min vector
- Aanderaa TR2 thermistor chain (50 m long, 11 sensors at 5 m spacing,
sampling every 30 min, suspended 10 m below the primary acoustic
instrument) from 35 m to 85 m
- WOTAN (Weather Observation Through Ambient Noise, sampling 16 times per
hour) at 87 m.
The following datasets are available:
+ Thermistor chain data: Data were sampled and stored every 30 min, and
good data are available for the period starting 12:00UTC on 22 October
1992 through 24:00UTC on 12 February 1993. Note: Since the instrument
was bottom-moored, the depth of the thermistor chain varied throughout
the deployment, from a minimum of 33 m to a maximum of 48 m at the top
of the chain.
+ Primary acoustic instrument data: The instrument collected an hourly
series of measurements of instrument depth, water temperature, and
conductivity. These data are available for the period starting
12:05UTC on 22 October 1992 through 02:04UTC on 6 March 1993. Sensor
depths range from 23 m through 38 m during that period.
