AKA: none

Other ID: J-13-94-MB,DSJ13

Status: Completed

Organization(s):

Funding Program(s): Monterey Bay National Marine Sanctuary (MU182)

Principal Investigator(s): Marlene Noble

Affiliate Investigator(s): Frank Schwing (National Marine Fisheries, NOAA)

Information Specialist(s):

Data Type(s): Environmental Data: CTD, Sampling: Biology, Sampling: Geology

Scientific Purpose/Goals: National Marine Fisheries (NOAA) provided the vessel to gather information on the density structure and water clarity of the water column during winter in and over Monterey Canyon. This information will be helpful in the interpretation of data from 6 current moorings that were deployed for a year in the canyon (Aug. 93-Aug. 94).

Start Date: 1994-11-13

End Date: 1994-11-16

Equipment Used: CTD, boxcore

Information to be Derived:

Summary of Activity and Data Gathered: CTD data was collected at 27 sites in the canyon in depths ranging from 80 to 2800 meters, this data will be processed and stored by MBARI. In addition to the CTD survey, 5 box cores were taken at various sites. One was collected in 1300 m, at a mooring site in Monterey Canyon that registered a probable turbidity current for a week or more last February. The others were in the head of Monterey canyon, head of Soquel canyon and at the junction where Soquel joins Monterey canyon.

Notes: We just got back from a great cruise on the David Star Jordan (even though it was November). National Marine Fisheries provided the vessel so we could gather information on the density structure and water clarity of the water column in winter over and in Monterey Canyon. This information will be helpful in the interpretation of data from the 6 moorings that we deployed for a year there. We also managed to collect 5 box cores. One was collected in 1300 m, at a mooring site in Monterey Canyon that registered a probable turbidity current for a week or more last February. The others were in the head of Monterey canyon, head of Soquel canyon and at the junction where Soquel joins Monterey canyon. These cores are part of our sediment budget program in the Monterey Bay Marine Sanctuary project.
