Purpose
|
To measure current velocities, waves, wind speed and direction, and
suspended sediment concentrations on the continental shelf off Amapa.
|
|
|
Information to be Derived
|
Current velocities, waves, wind speed and direction, suspended sediment
concentrations, conductivity, temperature, depth, continuous sub-bottom acoustic
profiles.
|
|
|
Summary
|
Instruments were deployed to measure current velocities, waves,
windspeed and direction and suspended sediment concentrations on the continental
shelf off Amapa. the instruments, which belong to Institito de Oceanografia
Universidade de Sao Paulo and Woods Hole Oceanographic Institute, were deployed
from three moorintgs at 18 m, 63 m, and 101 m isobaths. Additionally, limited
CTD/transmissometer (conductivity, temperature and depth/ suspended sediment
measurements) casts were made and continuous sub-bottom acoustic profile records
were collected while underway. Instruments belonging to the University of
Washington and the USGS were deployed on a bottom mounted tripod at a 63 m water
depth at site M-2.
