The data described here were collected on LTER02 which took place from 2001-09-07 to 2001-09-15 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 (Scanfish) 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 LTER02, additional CTD samples were collected to cross-calibrate between CTD and scanfish. On this cruise, additional stations and are identified as calibcast
