The site of the HyCODE field experiment is the New Jersey shelf of the NYB and the MAB in 24 m water depth.
We placed newly-developed optical and physical instruments at several depths on a mooring and a bottom tripod
at 39o20.47’N, 74o05.05’W from 16 May to 15 September 2000. Most of the instruments were recovered
and redeployed on 25 July 2000. A third deployment was conducted from 19 June through 6 August 2001. Physical and bio-optical instruments on the mooring include:
1) Wet Labs, Inc. ac-9s for absorption and attenuation at nine wavelengths
(5, 11, and 20 m);
2) Biospherical Instruments, Inc. PAR sensors
(QSP-200) for photosynthetically active radiation (5, 11, and 20 m);
3) Wet Labs, Inc.
fluorometers and transmissometers (WETStars and C-stars) for chlorophyll-a concentration and beam
attenuation at 660 nm, respectively (5 and 11 m);
4) Satlantic, Inc Minispecs for hyperspectral (3.3 nm resolution from 350-800 nm)
upwelling radiance (2, 5, and 11 m) and downwelling irradiance (surface, 5, and 11 m);
5) Hobi Labs Hydroscat-6
for backscattering at six wavelengths and fluorescence at two wavelengths (5 m);
Sea-Bird Electronics, Inc. SEACATs and MICROCATS for temperature and salinity (5, 11, and 20 m);
7) Onset Computer Corp. Tidbits for temperature (0.5, 11, 14, 17, 20, 22, and 23 m);
8) Sea-Bird Electronics, Inc. temperature sensors (SBE-39; 1, 3, 8, and 21 m); and
9) Sea-Bird Electronics, Inc. pressure sensor at 21 m.
10) An uplooking RD Instruments, Inc.
Acoustic Doppler Current Profiler (ADCP) was placed on a bottom tripod for currents binned every meter. The ADCP was not
recovered on 25 July 2000; it remained in the water continuously between 16 May and 15 September 2000. A water level sensor was
also mounted on the bottom tripod for wave height.
Sea-Bird Electronics, Inc. SBE 5T submersible pumps were also deployed at 5, 11, and 20 m for use
with the WET Labs, Inc. ac-9 and WETStar fluorometers.
The fluorometers and transmissometers were sampled every minute at a four second period. The sampling rate for the SBE-39
temperature sensors and SEACAT and MICROCAT temperature and salinity sensors was once per minute. The Tidbit temperature sensors sampled
once every five minutes. The sampling rate for the Hydroscat-6 was once per hour. The PAR was sampled eight times per hour.
The Minispecs sampled once per hour between 6 am and 6 pm, EDT. Lastly, the sampling rate for the ac-9 was once per hour for 30 seconds.
The ac-9 wavelengths are: 412, 440, 488, 510, 532, 555,
650, 676, and 715 nm.
