SBC LTER: CTD profiles from UNOLS cruises in the Santa Barbara Channel: LTER08, 2003-10-08 to 2003-10-17

The data described here were collected on LTER08 which took place from 2003-10-08 to 2003-10-17 on the RV Pt. Sur. Cruises have been conducted in the Santa Barbara Channel, California, USA, 3-4 times per year since March, 2001 and are approximately 7 days in length. There are 4 basic types of measurements: Profiles at 25 grid stations unique to the SBCLTER and 7 cross-channel stations (also occupied by the Plumes and Blooms project). Measurements include primary production, basic CTD parameters (Seabird 911-plus), inorganic nutrients, phytoplankton pigments, particulate organic carbon and nitrogen, natural abundances of N and C isotopes, and occasionally biogenic and lithogenic silica, optics, and/or dissolved organic carbon. Two-dimensional sections of oceanic constituents are recorded in the top 120m with an undulating towed CTD scanning system (Triaxis) on both along shore and cross-channel transects. Underway measurements: fluorometry, salinity and temperature are collected at a depth of 3m with a flow-through system which also includes continuous climate measurements. Underway acoustic dopler current profiles were collected using a RDInstruments Workhorse 300kHz ADCP. On Cruise LTER08, additional CTD samples were collected document the counter-current eddy, sample additional Plumes and Blooms stations, and sample off Santa Barbara Point. On this cruise, additional stations and are identified as CO01 to CO16, PNB000, and SBP, respectively
