Two deployments were made at this site.The first deployment was between Oct 28, 1994 andJan 21, 1995.The second deployment was between Apr 2, 1995 andSep 30, 1995.During the second deployment the transmissometer record appears to decline at a steady rate during mid-record.This maybe due to biofouling, but this trend does not appear in the fluorometer.

[ table of contents | back to top ] a slow response, frequency output temperature sensor manufactured by Sea-Bird Electronics, Inc. (Bellevue, Washington, USA).It has an initial accuracy of +/-0.001degrees Celsius with a stability of +/-0.002degrees Celsius per year and measures seawater temperature in the range of -5.0 to +35 degrees Celsius.more information from Sea-Bird Electronics Bird SBE-4 conductivity sensor is a modular, self-contained instrument that measures conductivity from 0 to 7 Siemens/meter.The sensors (Version 2; S/N 2000 and higher) have electrically isolated power circuits and optically coupled outputs to eliminate any possibility of noise and corrosion caused by ground loops.The sensing element is a cylindrical, flow-through, borosilicate glass cell with three internal platinum electrodes.Because the outer electrodes are connected together, electric fields are confined inside the cell, making the measured resistance (and instrument calibration) independent of calibration bath size or proximity to protective cages or other objects.Transmissometer can be deployed in either moored or profiling mode to estimate the concentration of suspended or particulate matter in seawater.The transmissometer measures the beam attenuation coefficient in the red spectral band (660 nm) of the laser lightsource over the instrument's path-length (e.g.20 or 25 cm).This instrument designation is used when specific make and model are not known.The Sea Tech Transmissometer was manufactured by Sea Tech, Inc. (Corvalis, OR, USA).chlorophyll-a fluorometer has internally selectable settings to adjust for different ranges of chlorophyll concentration, and is designed to measure chlorophyll-a fluorescence in situ.The instrument is stable with time and temperature and uses specially selected optical filters enabling accurate measurements of chlorophyll a.It can be deployed in moored or profiling mode.
