Measurements were collected using an RDI 600 kHz Workhorse Sentinel ADCP beginning 2005-12-15. The instrument depth was 015 meters, in an overall water depth of 015 meters (both relative to Mean Sea Level, MSL). The instrument was programmed with a sampling interval of 2.0 minutes and a vertical resolution of 1 meter.EARTH SCIENCE: Oceans: Ocean Circulation: Ocean CurrentsEARTH SCIENCE: Oceans: Ocean Temperature: Water TemperatureEARTH SCIENCE: Oceans: Ocean Pressure: PressureGlobal Change Master DirectoryTemperatureIntegrated Ocean Observing SystemIOOSIOOS Vocabulary Version 1Oceanographic Sensor DataBottom-mounted ADCP Current Profile DataNational Marine Sanctuary Program DataPISCO Categoriescontinental shelfcurrentsADCPPISCOCaliforniaUnited States of AmericaCINMSPISCO, CINMS and NOAA request that end-users acknowledge both entities in any publications using these PISCO/Sanctuary data. The acknowledgement should read: "This study utilized data collected by the Partnership for Interdisciplinary Studies of Coastal Oceans: a long-term ecological consortium funded by the David and Lucile Packard Foundation and the Gordon and Betty Moore Foundation. Some PISCO data are also provided by the National Oceanic and Atmospheric Administration." PISCO also requests that end-users provide PISCO with copies of any published manuscripts using the PISCO/Sanctuary data. Manuscripts should be sent to the PISCO Program Coordinator (contact information available at www.piscoweb.org.)

The base of the mooring is in 15 meters of water below Mean Sea Level (MSL), and it extends up to 4 meters below MSL. The altitudeMinimum and altitudeMaximum tags in this initial coverage section refer to the ADCP measurement range and are also referenced to MSL. They do not represent the overall water depth. Note the nominal range of the ADCP may extend from near-bottom (a depth expressed as a negative altitude) to slightly above MSL (a height expressed as a positive altitude).-120.311210-120.31121034.04017034.040170-0154meter2005-12-1518:18:40Z2006-03-2320:16:40ZThese data were collected by PISCO to understand the physical processes of the inner continental shelf and their potential effects on marine ecology.Physical Oceanographic Data ManagerPISCOphys-ocean-data-manager@lists.piscoweb.orghttp://www.piscoweb.orgMethods for PISCO bottom-mounted ADCP collection and quality-control are available online, see the protocol citation.PISCOhttp://www.piscoweb.org/data/protocols/UCSB_moored_ADCP_protocol_No_1.pdfRDI 600 kHz Workhorse Sentinel ADCPIn this sampling section the altitudeMaximum tag refers to the altitude of Mean Sea Level (MSL), and altitudeMinimum tag refers to the nominal altitude of the sea floor.

An interdisciplinary collaboration of scientists from four universities, PISCO integrates long-term monitoring of ecological and oceanographic processes at dozens of coastal sites with experimental work in the lab and field. We explore how individual organisms, populations, and ecological communities vary over space and time. Findings are applied to issues of ocean conservation and management, and are shared through our public outreach and student training programs.PISCO is funded by the David and Lucile Packard Foundation and the Gordon and Betty Moore Foundation.cn=data-managers,o=PISCOGROUPS,dc=ecoinformatics,dc=orgallpublicreadBAYXXX_015ADCP015R00_20051215.40.2.txtBAYXXX_015ADCP015R00_20051215.40.2168959163ASCII1#x0Acolumn#x20ecogrid://knb/BAYXXX_015ADCP015R00_20051215.40.2dateGreenwich Mean Time calendar date of each ADCP measurement record, using ISO 8601 standard format YYYY-MM-DDdateYYYY-MM-DD1 daytimeGreenwich Mean Time of each ADCP measurement record, to the 1/100th of a second, using ISO 8601 standard format hh:mm:ss.ssZ.
