AKA: none

Other ID: W-1-97-NC

Status: Completed

Organization(s):

Funding Program(s): Internal Waves over the Upper Continental Slope off Northern California (MU150)

Principal Investigator(s): George Tate

Affiliate Investigator(s):

Information Specialist(s): Joanne C. Ferreira

Data Type(s): Time Series: Mooring (physical oceanography), Environmental Data: Temperature, Environmental Data: Current, Environmental Data: Conductivity, Environmental Data: Turbidity, Sampling: Geology

Scientific Purpose/Goals: To measure the internal wave field on the upper continental slope over long time duration (> 1 year), and to estimate the effects of internal waves on the transport of sediment over the slope.

Vehicle(s):

Start Port/Location: Newport, OR

End Port/Location: Newport, OR

Start Date: 1997-01-22

End Date: 1997-01-22

Equipment Used: instrumentmooring, temperature, currentmeter, tempsalinometer, transmissometer, sedimenttrap

Information to be Derived: Seasonal changes in the internal temperature field over the slope, with analysis of the internal waves in this region.

Summary of Activity and Data Gathered: Time-series measurements (hourly) of temperature at 12 depths, currents and light transmission at three depths for over one year. This mooring was in 450m water depth; USGS had 11 temperature sensors at 150m, 200m, 250m, 300m, 320m, 340m, 360m, 380m, 400m, 420m, and 437m; University of Washington had current meters, conductivity gauges, temperature sensors, and light transmission meters on the mooring at 60m, 180m, and 435m; and SUNY had sediment traps on the mooring.
