Dataset acquisition description

   PI:              Thomas Dickey and Dave Foley
   of:              University of California, Santa Barbara
   dataset:         Multi-Variate Moored Systems data from Instrument at 25m
   dates:           May 1, 1992 to September 14, 1992
   location:        equator at 140W
   project/cruise:  EqPac
 
 These data were taken as part of the EPOCS mooring PR07.  The data
 included with this set are those specific to the Multi-Variate Moored
 Systems (MVMS) deployed by Tom Dickey (USC).  In order to provide the
 community with manageable files, the original data (3.75 minute
 sampling period) has been averaged into 1 hour bins.  If higher time
 resolution is required, I can make the necessary arrangements.

	Complimentary data from the other instruments on the mooring
 are also available through Mike McPhaden's group (or through me, with
 their permission) at NOAA/PMEL.  These data include: ADCP (8m bins),
 Various temp. and mechanical current meters, and surface buoy
 meteorological data (winds, humidity, solar insolation, SST, air T).

Multi-Variate Moored System

Supplied Name: Multi-Variate Moored Systems

Supplied Description:

The mooring data are collected with Multi-Variate Moored Systems (MVMS) deployed by Tom Dickey (USC).

Instrument Type

Generic Name: Multi-Variate Moored System

Acronym: Multi-Variate Mooring

Community Identifier: http://vocab.nerc.ac.uk/collection/L05/current/102/

Generic Description:

The Multi-Variate Moored Systems deployed during the US JGOFS EqPac Process Study was a package of integrated meteorological instruments. The Multi-Variate Moored System included instruments for measuring bio-optical and physical variables including water temperature, current direction and velocity, PAR, Lu683 (upwelling radiance, chlorophyll a fluorescence), and salinity. Instrumentation included: (1) a vector measuring current meter (VMCM; EG&G; Weller and Davis, 1980); (2) a fluorometer measuring strobe-stimulated fluorescence (Sea Tech; Bartz et al., 1988); (3) a transmissometer measuring beam transmission at 660 nm (Sea Tech; Bartz et al., 1978); (4) a sensor measuring scalar irradiance or photosynthetic available radiation, PAR, (E-PAR) in the visible waveband (400 < 700 nm, in vacua; Biospherical Instruments, QSP-200; Booth, 1976); (5) a sensor for measuring downwelled vector irradiance at 488 nm (Ed(488); Biospherical Instruments, QCP-200); (6) a sensor for measuring upwelled radiance at 683 nm (Lu683); Biospherical Instruments MRP-200); (7) a dissolved oxygen sensor (ENDECO, Inc.) and thermistors for measuring temperature. (Dickey et al. 1993 and Foley et al. 1997).
