A. Lavrentiev. The primary objective of these cruises was mooring work in the Bering Strait region. Related high resolution CTD sections with nutrient sampling and some benthic grab work were performed as weather and time allowed, in order to provide context to the mooring data and to measure the hydrography of the southern Chukchi Sea. This dataset contains processed CTD data (temperature, conductivity, pressure, salinity, sigma-t) from 2005, 2006, 2007, 2010, 2011, and 2012. Bad weather in 2008 did not allow CTD casts to be taken during the cruise aboard the Academik M. A. Lavrentiev. Data from 2004 and 2009 were processed separately, though might be included in this data set at a later date. Nutrient data are not included here, though the voltages reported by auxiliary sensors (PAR, fluorescence, oxygen, altimeter) are included when available. Refer to the .readme files for listings of exactly what data are available for each cruise. Information on each year's cruise and data processing idiosyncrasies is included in a .readme file included with the year's .ascii data file. Information on station position and time are included in the .hdr file. More information on cruises can be found in the cruise reports posted at http://psc.apl.washington.edu/HLD/Bstrait/Data/BeringStraitCruiseDataArchive.html. This dataset is available to the public for a wide variety of uses including scientific research and analysis.

NOAA National Centers for Environmental Information custodian CTD CTD Conductivity-Temperature-Depth probe fluorometer fluorometer fluorometer oxygen sensor oxygen sensor Any instrument that measures oxygen content in a compound. PAR Sensor PAR Sensor Photosynthetically Active Radiation Sensor The PAR sensor measures global solar radiation from 400 to 700 nm, which approximates the spectral band active in photosynthesis. The response of the instrument falls sharply to zero on either side of this band, and between 400 and 670 nm it increases monotonically from about 50% to 100%. There is no protective glass dome over the receiving surface. Irradiance from the sun passes through a small white visible bandpass filter/diffuser in the shape of a horizontal disk at the top of the instrument. Within the instrument radiation is directed through a series of colored glass filters and onto a silicon photodiode detector. The factory-supplied calibration converts the signal from the detector to a flux of photons in micro-mole (of photons) s-1 m-2. (One micro-mole equals 6.022 E17 photons.) For the solar spectrum, these units may be converted to watts per square meter by dividing by 4.6. (http://www.srrb.noaa.gov/instrument/par.htm) Akademik M. A.
